Executive Summary

The goal of this phase of our design project was to generate design ideas that would answer stakeholders needs on today's commercial snowboards. Our group conducted an extensive market research in order to identify the main stakeholder needs, so that we can come up with appealing design ideas for the snowboard. Because the rider is the main user of the snowboard, we decided to target our market research toward the needs of the end user. After doing anthropological observations based on previous experiences and online videos, interviewing users, reviewing online product reviews and doing an online survey, we narrowed our list of user's needs from Report 1 down to the most important ones, and we found many other areas for improvement. These product opportunity gaps include the problem that users have when they try to skate with their board in the ski lift line, the long time needed to adjust the angle of the bindings, or the difficulties that snowboarders experience when they try to take the T-lift or J-bar. We then came up with a list of 100 design ideas, and selected the 3 top ideas based on the most important needs identified and what would feasible within one semester. These top ideas are a foldable snowboard with adjustable dynamics, easily turnable bindings and easy release bindings. After comparing each of these ideas with relevant competitor products on two separate Pugh charts, we decided to choose the foldable snowboard as our main design ideas. In addition to answering the need for easier storage and transport, this design idea would enable the snowboarder to ride in different conditions, as the flexibility of a snowboard affects its handling. A softer flex makes turning easier, while a harder flex provides more stability at high speed. There are currently on the market different kinds of snowboards to suit these different riding styles, and the foldable snowboard would combine the riding advantages of all of them. Finally, we set a plan for the remaining of the semester by making a Gantt chart.

Market Research

Anthropological Observation

From our groups past experience of going several times a year to different ski resorts in the US and Europe, coupled with online video research we made several observations.

The first step to snowboarding is getting to a ski resort. The majority of snowboarders arrive in cars to the resort. Those who live far from the resort will often have to fly to somewhere close to the resort before renting a car or use public transport to get to the resort. Many snowboarders prefer using their own board rather than to rent. Most airlines count one snowboard bag and one bag containing only boots and bindings together as 1 piece of luggage [1]. This means in order to bring another bag with clothes a snowboarder must check in at least two pieces of luggage. Therefore many snowboarders at airports end up carrying a bag with a snowboard, a bag with bindings and a bag with clothes which is bulky and inconvenient. For car transport, the majority of snowboarders transport their boards on a ski rack on the roof of the car, as most cars do not have space for them inside. This causes drag and loss in fuel economy, as discussed in the DFE analysis of our previous report.

When moving from their cars to the ski lift, snowboarders seem to be quite confortable as they only have one piece of equipment and fairly confortable boots, especially when observed next to skiers who have two skis and two poles to carry and have much more unconfortable boots. There are several different ways to carry a snowboard the most common being holding it at their side. Other common possibilites are behind their back, or on their shoulders. [2]

However one of the most common problems experienced by snowboarders is struggling getting on and off ski lifts. Snowboarders, especially beginners have great difficulties getting on J-bar(button lift) and T-bar lifts. These lifts originally designed for skiers requires that the snowboarder places the bar or disc agaist the inside of their leg. As the lift is moving at fairly high speeds when placed between the snowboarders leg, it can cause the snowboarder to lose balance and fall. This is an issue which can be both painful and embarrassing for the snowboarder, as not only does he/she fall but can risk getting dragged along on the ground by the lift still between the legs. This problem also affects the other users and ski resort owners as it increases queue time, as several lifts are wasted during the time the snowboarder gets back up and attempts again, often several times. Due to some snowboarders lack of confidence in these lifts they also often waste time by letting several lifts pass them by before attempting to mount the ski lift. Although less common than the T-lifts, J-bar lifts cause even greater problems for snowboarders as the disc surface designed to attach between the legs of skiers has very little surface that can be placed parallel to the snowboarders leg. [3] [4]

Furthermore we looked at snowboarders taking chairlifts. When taking ski lifts (either chairlifts or bar lifts) snowboarders detach their back foot from their binding. Getting on chairlifts does not cause many problems for either skiers or snowboarders. However this is not true for getting off chairlifts. When exiting a chairlift, one moves at the speed of the lift as one slides off. This does not generally cause skiers any problems as their boots remain in skiing position during the chair lift, but for snowboarders it can be difficult to get their balance with only one foot strapped in which often cause them to fall over as they exit the chair lift. One person falling can cause a chain reaction as they block the exit area, making it more difficult for those on the next lift to remain on their feet. [5]

After exiting a ski lift, skiers can begin skiing straight away, often using the speed of the lift to get to the inclined slope, or using their poles to take them there. Snowboarders usually sit down after the ski lifts in order to strap their boots into the binding, thus losing the speed from exiting the ski lift. There is often a flat part between the ski lifts and the inclined part of the slopes and snowboarders either have to push along with their free foot, which is difficult given the approximately 90 degree angle between the board and the binding or acwardly step with one foot lifting the board. [6]

Certain ski resorts have slopes which have an incline followed by a flat part. Many riders, both skiers and snowboarders do not have enough speed from the incline to get past the flat part of the slope. Skiers can use their poles to move forward if stuck on the flat, and can also move their skis to create forward motion. Snowboarders either have to unstrap and slide along as described before or use their board to either wiggle or jump forward, another possibility is leaning down and pushing with their hands, all methods are slow, uncomfortable and requires a lot of energy. [7] [8] [9]

User Interviews

We conducted two user interviews with Evan Waldens brother and Erik Ringvolds mother Trude.

Trude is a 56 year old, very active woman who runs, bikes or skis (depending on the season) at least 6 times a week. However, she has arthritis making her fingers very weak. This condition is worsened by the cold, which means strapping on ski boots sufficiently tight on top of a mountain is impossible. Also the weigth of carrying skis from the car to the ski lift can be challenging for her, especially if the car is parked far away. Another point brought up, was that she belives snowboarders have much less control in the slopes than skiers, and she tries to keep away from them as she had an accident 2 years ago, where a snowboarder collided into her causing several months of pain and disability to do sports.

Conclusions: Although snowboard bindings are different than ski boots, they work on the same principle, and people with arthritis would probably struggle with their snowboard bindings, especially if their fingers are cold. The weigth of a snowboard is also a little less than skis but for older users or children it can be difficult to carry the board. However statistics from the National Institute of health shows that its not true that snowboarders have less control than skiers. They are equally prone to accidents altough snowboard accidents tend to be less severe. [10]

Adam is a 42 year old who has been snowboarding since 1993 (about 19 years). He mostly does resort snowboarding in USA, but has done some snowboarding off of Helicopters and off of snow cats. Helicopter snowboarding take people to mountains that have never been boarded on and allows for bordering on extremely powdery snow.

Adam owns his own snowboard. When he goes snowboarding locally he puts his snowboard in a bag and sticks it through a slot between the drunk and the back seat. However, for longer trips and trips that require him to drive more than one other person he must rent a snowboard rack. On trips where he has to fly Adam must check his snowboard as a separate bag of luggage.

Adam uses step in bindings. He doesn't remove his bindings from his board because it takes a while to attach them. He folds the back support of the binding down so the board takes up a little less space. Adam tends to keep his back foot out of the bindings when he rides the ski lift. He has a black pad on the board near the back binding that he puts his foot on when he is getting off the lift.

Snowboard can be either asymmetrical or symmetrical. This has to do with binding placement and whether or not a board can be ridden "goofy". Adam uses a semi-asymmetric board where the bindings are slightly off-center towards the back of the board. When riding on more powdered snow a boarder wants to be farther back on the board.

Adam doesn't know much about the dynamics of a board; however, he does know that boards often vary in degree of stiffness. A stiffer board offers more control and translates a person's movements to the board better. A softer board can move around a bit more on it's own, but is better for doing jumps and tricks.

Adam replaces his snowboard about once every 8 years. He only gets new boards because of the new technology that comes out. His board doesn't wear out because he rides mostly on powdery snow; however, a board that is ridden on ice will need to be replaced more often.

Adam is uses to skating on a board with his foot at the typical awkward angle. He enjoys being able to kick off on both the toe side and the heel side of the board. He also enjoys being able to glide on the board in his typical snowboarding stance after he kicks off. He acknowledges that a rotating binding might be more useful for a beginner who isn't used to the awkward motion.

Adam is interested in a fold-able snowboard, but he is very concerned with what he would be losing with regards to stiffness and rigidity. If the fold-able board maintains the dynamics of a regular board then he would appreciate the portability of a fold-able snowboard.

Some other innovations Adam is interested in is include terrain mapping goggles and snowboards with motorized tank tracks. Terrain mapping can be included in the helmets that most snowboarders wear now days. Additionally, Adam remembers the pain that accompanies the steep snowboarding learning curve. He believes their is an opportunity for snowboards that help keep people from catching edges and going into trees. A snowboard can also be designed for teaching kids. A tandem snowboard might be useful as well.

Conclusions: Adam doesn't have any big complaints with regards to his snowboarding experience. After 19 years of experience, he has gotten used to many things that he once would have called awkward/annoying. He is most interested in snowboarding accessories and novelty features. The three innovations he is most interested in are the board that prevents the rider from catching an edge, the terrain mapping goggles, and the fold-able snowboard.

Online Product Reviews

From product reviews at amazon.com we were able to exctract information about possible opportunities to improve todays snowboards. The reviews of the board itself were generally extremely positive. Most people commented positively on the boards dynamics such as flexibility, stable at high speeds, soft landings, good on all terrain and there were comments on boards being lightweight. The only negative comment was about a board getting cracks on the top surface, but after being left in a moist bag for several months. We looked at reviews for snowboard wall racks, where we saw comments on people being satisified to get more space in their room, due to this device [11]. The reviews for bindings was much more negative, the vast majority concerned parts not working correctly or breaking after using them only a few times. Users also complained about children not being able to put on their own bindings, the plastic bindings become stiff and hard to manipulate during winter temperatures, bindings unlocking while riding, bindings filling up with snow while riding [12]. Another comment described how the strap was too long and ended up touching the snow and acting like a break, which is a serious design flaw. [13]

We drew the following conclusions from the product reviews:

- The board is very optimized, litte room for improvement
- Some users would benefit from an easily storable snowboard
- There are several problems with the bindings, manufacturing as well as design flaws

Online Forum Survey

We conducted a survey [14] on reddit.com a snowboard forum, asking snowboarders if they would benefit from the idea of a foldable snowboard, considering it had the same dynamic properties as a regular snowboard. The answers consisted mostly of people thinking that it can not be done. One person expressed interest in this kind of snowboard and another said it would not be useful as the snowboard was not the most ackward thing to transport, but rather the boots, helmet and clothing.

Top Stakeholder Product Needs

We identified four major stakeholders in the life cycle of the competitor's product: the user, the retailer, the manufacturer and the shipping company. After the market research we decided to focus on the user product needs. The product is produced for the user, therefore his needs are the ones that should be first taken into consideration when redesigning the competitor's product.

This is the list of user needs from our initial report completed with needs found from market research:

  • Low price
  • Light with sufficient rigidity and flexibility
  • Durable
  • Board should have sharp edges but remain safe to carry
  • Adjustability and strength of bindings
  • Ergonomics of bindings: they should be easy to strap on and release
  • Appearance, branding
  • Easy to transport
  • Easy to store

Top Design Concepts

Through careful market analysis and numerous idea generation sessions several design concepts were developed and are presented below.

Foldable Snowboard

Foldable snowboard concept
Foldable snowboard concept

The top design concept developed was for a foldable snowboard with adjustable dynamics. Transportation of snowboards is a critical concern throughout all market segments, from amateur weekend warriors to seasoned professionals. The dimensions of commercial snowboards often necessitate the use of specialized bags and car racks, which can be expensive and inefficient (in the case of roof mounted racks). By redesigning the snowboard to fold in half, standard bags can be used when travelling to the resort and equipment can more easily fit within smaller vehicles, thereby improving fuel economy and decreasing transportation costs. In addition, the foldable design allows for more efficient storage of the board when not in use. Splitting a snowboard in half, however, affects the spring and damping coefficients of the board, thereby influencing the riding experience. To counteract this effect, this design introduces an adjustable spring damper mechanism, which can be tuned to restore the dynamic properties of the board. Furthermore, this setup also allows riders to tune their boards to their particular riding style or the terrain they will be riding on. This feature allows beginning riders to experiment with different board dynamics without purchasing additional boards, and can potentially replace several boards from a more experienced rider's collection.

Easily Turnable Bindings

Rotating binding concept

The rotating binding is an innovation that will make it easier for people to go from lift to lift on a snowboard. It will also allow people to customize the angle of their bindings more easily. When the lever on the back of the binding is pressed down it releases the top part of the binding. This allows the user to lift the top layer far enough so that the interlocking teeth are no longer engaged. With the teeth not engaged the user can rotate the binding to whatever position he/she wants before lowering the top part until the teeth are engaged in their new position and the lever locks back into place. Many users have complained about the difficulty of skating with a snowboard because of the awkward angle their front foot is placed at during conventional use. This is especially true for beginning snowboarders who haven't yet gotten used to the awkward skating. The rotating binding allows users to rotate their front binding into a position that is more suitable for skating.

Easy Release Bindings

Conventional and easy release binding overview

Easy release binding detail
Easy release binding detail

The innovation of the easy release binding is to reuse most of the conventional binding. Normally, a disk mounted to the board at 4 points, is used to hold the baseplate to the board. Both the disk and the baseplate are notched to allow many orientations of the baseplate to acommodate different riding stances. The radius of the hole in the baseplate is smaller than the radius of the disk by the width of the notches. The redesign shrinks the disk to allow it to be mounted permanently. Its radius is shrunken such that the base plate will fit over it. To mount the baseplate securely, the user simply places it over the permanent disk, and twists the center knob clockwise. This turns an inner disk with 4 curved slots which push pins outward that are connected to 4 wedges that slide out of the top half of the disk. The wedges engage with the notches in the baseplate and hold it firmly in place. The center knob is low enough not to protrude into the sole of the users boot when the boots are strapped in conventionally. To remove the binding, the user turns the knob counter clockwise and lifts the baseplates out. This system is advantageous because it reuses most of the binding hardware already present, which helps improve its DFE score. If the easy release binding is adopted, manufacturers could sell bindings without the disk, given that a customer already owns one set of easy release disks. If reliability and durablility can be proven, the easy release binding provides a viable alternative for the high-end snowboard consumer.

Competitor Products

We begin by reviewing the different kinds of conventional snowboards that exist on the market. Then, we take a look at three innovations that have appeared recently: the splitboard, the Magne-Traction Snowboard and the Swivler Rotating Binding Attachment.

Common Snowboards

Snowboarding is a sport that has developed into various styles, the most common ones being freeride, freestyle and freecarve. Each snowboarding style requires a specific equipment that suits the technique needed for that particular style. While all common snowboards are constituted of a board and two bindings, there are various kinds of snowboards that have different shapes and flexibility, and different kinds of bindings. [15] [16]

Freestyle

Fig. 2: Strap-in Binding
Fig. 2: Strap-in Binding
Fig. 3: Step-in Binding
Fig. 3: Step-in Binding

Freestyle snowboarding consists of performing tricks on man-made terrain features such as rails, jumps and boxes. It usually takes place in parks and urban areas. The snowboards used in freestyle are twin-tipped, which means that both ends have an identical shape. They have a short length, are quite flexible and are used with soft boots. The bindings used are either strap-in bindings, where the boot is retained by an ankle strap and a toe strap, or step-in bindings, where a locking mechanism automatically secures the boot when it is inserted into the binding. Freestyle snowboards are the most popular kind of snowboards, also being used by people going down groomed slopes in ski resorts. The snowboard dissected in Report 1 belongs to this category. For it is the most common kind of snowboard, this is the competitor product against which we will oppose our design ideas.

Freeride

Fig. 4: Freeride Snowboard
Fig. 4: Freeride Snowboard

Freeride snowboarding consists of riding down any terrain available, but most often groomed runs. Freeriding includes aerial tricks, borrowed from freestyle, and deep carve turns, common in alpine snowboarding. The snowboards used are longer than freestyle boards and have a moderate to stiff flexibility. They have a directional shape, with a wider and longer nose for more flotation on the powder. Like in freestyle, soft boots are used with either strap-in or step-in bindings.

Freecarve

Fig. 7: Plate Step-in Binding
Fig. 7: Plate Step-in Binding

Freecarve or alpine snowboarding takes place on groomed slopes and consists of making clean and smooth turns. In order to achieve the most efficient carved turn, the snowboards used are long, very stiff and narrow. They have a directional shape and a larger sidecut radius to facilitate carved turns at high speed. They are used with hardshell boots and plate bindings. Plate bindings exist either as manual bail bindings, where the boot is retained by a heel bail and a manual toe clip, or step-in bindings, where the boot is secured by a toe bail and an automatic heel locking mechanism. [17]

Splitboard

Fig. 8: Splitboard
Fig. 8: Splitboard

A splitboard is a snowboard made of two halves secured together by the bindings. When the bindings are removed, the snowboard splits in half lengthwise. By connecting each binding longitudinally on one half, the snowboard is transformed into a pair of cross country skis. The user then covers the bottom surface with a removable skin that enables him to travel into the backcountry and climb to the top. Once the user is ready to descent, he only has to take off the skin and bindings, join back the two halves together and put the bindings back into snowboard configuration. Splitboards are less efficient than snowboards but are very convenient for trek enthusiasts.

Magne-Traction Snowboard

Fig. 9: Magne-Traction Snowboard (notice the seven small bumps on each side)
Fig. 9: Magne-Traction Snowboard (notice the seven small bumps on each side)

Magne-Traction is a new design for snowboard sidecuts that tries to solve the problem of loss of control during turns on icy surfaces. Rather than the sidecut being only one concave curve, Magne-Traction features many wavy bumps along each side of the sidecut, in an attempt to provide more contact points between the ice and the cutting edge of the board when turning. As a consequence, the edge hold and control during icy conditions should be improved. [18]

Swiveler Rotating Binding Attachment

Fig. 11: Swiveler Rotating Bindings

Fig. 12: Swiveler Rotating Bindings

This innovative product tries to solve the problem of moving on a flat surface with one foot attached to the snowboard. What happens usually is that users struggle to advance on flat surfaces (for instance in the ski lift line), because the foot is attached perpendicularly to the board, making skating on the board very awkward. The Swiveler Rotating Binding Attachment is a swivel pivot plate that goes between the bindings and the board. By pulling a cord, the plate can easily swivel, allowing the user to rotate its foot to an angle parallel to the board. He can then skate with his front foot straight as if he was on a skateboard. Also, during the ride on a ski lift, this position eliminates the pain caused by the board twisting the knee. [19]

Conclusions

Commercially available snowboards are designed to provide various dynamic properties to suit the styles of individual riders, but do little to address the problem of efficient and convenient board transportation. The available snowboard form factor calls for specialized bags to house the board during air or bus travel or rooftop racks when the board is too large to fit within the vehicle. While commercial split board designs can reduce the width of the board for transportation, the problematic length of the board remains unchanged. This suggests a potential area for innovation where a snowboard could be spilt in half width-wise, to decrease the total length of the board and allow for easier transportation.

  • Foldable Snowboard with Adjustable Dynamics
    • The foldable board is designed to split in half for transportation and easily bolt together once on location. After the board is assembled, it can be used just as easily as a regular snowboard or split board. The value of the design is clear when considering ease of transportation and storage. Because the length of the foldable board is half of competing snowboards, more generic bags can be used and boards can more easily fit inside vehicles, eliminating the need for a rooftop rack and thereby improving fuel economy. The decreased dimensions of the board also make it easier to store for users and retailers alike. Splitting a snowboard in the middle unfortunately changes the dynamic properties of the board, however, this offers the opportunity of developing a new adjustable dynamics feature. By adding spring dampers to the board, the original board dynamics can be restored and tuned to match individual riding styles or terrain conditions. While the spring damper mechanism will add weight to the board, increase manufacturing costs, and provide an additional point of failure, the demand for such a feature spans multiple market segments from amateurs to professionals. One area that will require particular investigation is the degradation of the board's turning performance due to the split in the edges of the snowboard. If this effect is negligible or at least on par with the performance hit split boards introduce, we believe consumers will tolerate the increases in weight, cost, and potential for board failure in order to take advantage of the tremendous transportation benefits and the new adjustable dynamics feature.

Conclusions

The standard snowboard binding is tested and proven. It is durable and simple, which make it safe, easy to manufacture, and relatively easy to use. Any improvement to binding design needs to match the customers expectations of durability and saftey of the standard binding. Areas identified for improvement are

  • Facilitating scooter-like self propelled forward motion of the rider while on flat ground using the rear foot
    • The Easily Turnable Bindings allow rotation of the forward foot, so a rider can face forward while pushing with the rear foot. Rotating the front foot reduces strain on the riders ankle. The Easily Turnable Binding can take on any angle, as it uses a toothed locking mechanism similiar to the disk-baseplate interface. The market niche for a rotating front binding may be saturated already, however, as the "Swiveler" rotatiting binding attachment has made inroads. The Swiveler's innovation is that it is designed to interoperate with as opposed to replace current bindings. It is a thin disk that fits between the binding attachment disk and the mounts on the board. A shortcoming of the Swiveler is that it only allows rotation to two fixed positions, one for riding and one for scooting. The swiveler does not seem widely used or marketed, so introducing a competitive product is unlikely to yield widespread adoption.
  • Reducing the time spent replacing a board's set of bindings.
    • The Easy Release Bindings address this need by providing a quick release mechanism for binding removal. This mechanism is easy to install and use because it is designed to interoperate seamlessly with exsisting bindings. Current bindings use a disk which is mounted to the board at 4 points, and holds the baseplate in place. The disk and baseplate are notched to allow rotation of the baseplate to accommodate the stances of different riders. The Easy Release Binding replaces only the disk which holds the baseplate, and allows for quick baseplate removal, while remaining permanently attached itself. Provided that durability and safety are at least equivalent, the Easy Release Binding could make a very effective addition to the equipment of many an advanced snowboarder. Since it only caters to advanced riders, the market may be too small to justify mass production.

Conclusion

Snowboarding is a relatively new winter sport (1965, http://en.wikipedia.org/wiki/Snowboarding#History), and is undergoing constant evolution. We have explored several innovations that build on the original snowboarding concept. Two areas selected for improvement were the bindings and the board itself. Snowboard bindings rigidly fix riders' feet to the board, which can be difficult when they attempt to efficiently propel themselves across flat ground. It is common practice to leave the front foot strapped in, while pushing oneself forward with the rear foot in a scooting motion. Stresses strain the front leg, since the front foot is pointed nearly perpendicularly to the direction of motion. A way to effortlessly rotate the front foot to point it forward could alleviate the issue. We considered the idea for a rotating front binding, but market research, including analysis of competing products, showed that the demand for such an improvement is relatively small. To achieve a broader impact, we considered the issue of snowboard transportation. Snowboards are large and unwieldy, especially in their long dimension. Transportation of snowboards requires specialized bags, car racks, or, during air travel, suitcases, and these present an added cost to the consumer and the environment. The innovation is to fold a snowboard in half, such that conventional, preexisting carrying devices can be used, and thus facilitate transportation. From the market research we definitly feel there is a market for snowboarders who would buy a foldable snowboard, if it could perform as good as, or close to a regular snowboard. Although the Pugh chart comparison was fairly equal for the regular board and the foldable board, we belive that for a certain group of users, the advantages gained by being able to fold the board are worth it. A foldable snowboard has a wide market, as its benefits are enjoyable by all types of riders in all parts of the world. Furthermore, a folding snowboard presents an exciting design challenge, as halving a snowboard and reattaching the halves severly impacts its mechanical properties. The hardware restoring these properties, including bending moments and frequency responses, must be efficiently designed to minimize additional weight to the board, while providing the boards original properties. This innovation can be taken further, since the property restoring hardware can be utilized to tweak the properties as well. Thus, a single board could be tuned to accomodate a variety of riding styles, and potentially replace an advanced riders collection of boards designed for various conditions. While the addition of a folding mechanism increases the cost of manufacture and retail, it introduces a slew of new efficiencies, from reduction of transportation cost, elimination of car roof racks, to consolidation of snowboard collections. As it has the farthes reaching impact, solves a common problem, and presents an exciting engineering challenge, we propose to build a folding snowboard.

Hypothetical User Scenario

David is a devoted snowboarder who makes the trip to his nearest ski resort every other week during snowboard season. David recently bought a foldable snowboard from FoldableSnowSports inc. David usually drives with several friends, one of whom has a car with a ski rack. Occasionally he drives to the resort himself, his car does not have a ski rack, but since his board folds in half, he easily places it in the trunk of his car, happily knowing he is not wasting fuel by placing his board on the roof. Once a season David gets on a plane and goes to a resort with better slopes. In previous years David always brough three bags with him, one for the board and one for the boots and bindings as well as one for his clothes and other stuff. The airlines charged him for two bags, as a snowboard bag and a boot-binding bag are charged as one piece of luggage. David still used to prefer this to renting a board once there, as this costs extra money, and he prefers using his own board and own bindings when snowboarding. Since he brought his new board however, he manages to place the board inside his regular luggage saving the cost of the extra bag and more importantly making the trip go much smoother as he only has one bag to deal with instead of his previous three bags. David is a student and lives in a small dorm room. His previous board used to take up a large amount of space on the floor of his room, as it was difficult to balance it in a vertical position. He now leaves his new board folded and in a vertical position, taking up only a fraction of the space of his old one. Although the board cost him 100$ more, and the dynamics of the board are sligthly worse than those of his old board, David is overall very happy with his choice as in his opinion the advantages outweigh the negatives. Finally he loves the attention he gets from other curious snowboarders as he carries his board in the folded position on the ski resort parking lot.
