Executive Summary

Provide a brief executive summary that describes your key findings and recommendations.


Market Research

Provide a description of your market research and observations. Include pictures to communicate key observations where possible. Summarize top stakeholder product needs in a list.

Competitor Products

These reviews were collected by interviewing users who have used the standard peeler and online reviews of each competitor products.

The following are the user reviews of different competitor products. Contradictory statements are made by different users.

Standard Peeler

Pros

  • Easy to clean.
  • Easy to use.
  • Can peel vegetable such as potatoes and other firm vegetables but not as easy as apples.
  • Can be used for other purposes other than peeling, such as making curly fries and hash browns.
  • Suction cup base is much better than the model with clamp.
  • Metal structure more preferable over plastic device.
  • Safer than conventional hand held peeler.
  • Even kids are able to use it with not problems.
  • Relatively robust for apples of various sizes and shapes.
  • Core removing mechanism is favorable.

Cons

  • Core is wasted if corer/slicer is used to slice the potatoes.
  • Suction cup loses its adhesion capability if immersed in water, but recovers after time.
  • Butterfly nut cannot be hand tightened, or the corer/slicer will move. Pliers are required.
  • Corer/slicer is hard to realign once removed.
  • Only peels fraction of the apple even with fine tuning.
  • Core broke in half during the process making clean up difficult.
  • Device is too small for medium to large potatoes.
  • Suction cup loses its suction while the peeling process.
  • Spring which hold the peeler blade is too strong which causes the peeler to peel off more than desired.
  • Handle disconnects from the arm.
  • Device rusts after a period of time.
  • Leaves skin at top and bottom.
  • Some apple wasted since the blade digs deeper than desired.
  • Hard to clean the device with all the screws, springs and nuts.
  • Blade exposure is dangerous.
  • Do not want to eat apple in slices/spirals.
  • Usage is confusing when first seen without user manual.
  • Not a favorable aesthetic, the design is outdated.
  • Too heavy.
  • Concerned with potential rusting which may cause food contamination.

Hand Held Peeler

Pros

  • Small and simple. Storage is easy.
  • Easy to clean.
  • Cheap.

Cons

  • Tiring and time consuming to peel.
  • Chance of injury is very high.
  • Irregular peeling.

Electric Peeler

Pros

  • Easy to clean.
  • Very fast.
  • Very robust. Can peel potatoes of different sizes and shapes with no problem.
  • Does not peel excessively.

Cons

  • Noisy.
  • Does not peel the skin off the 'eye'.
  • Relatively expensive for a single purpose device.

Top Stakeholder Product Needs

  • Maintainability
  • Easy to clean.
  • Reduced risk of rusting.
  • Safety
  • No blade exposure.
  • Aesthetics
  • Device design need to be favorable.
  • Performance
  • Skin need to be completely peeled.
  • Variability in processing style.
  • No excessive peeling.
  • Ease of use
  • Use and function of the device must be intuitive.
  • Single or two step process is much preferred.
  • Device must be stable for satisfactory performance.
  • Light weight and compact.
  • Value for money
  • Device may have better performance but the value for money may be low.

Project Plan

Gantt Chart

Gantt Chart is convenient for project planning.
1) Divides a complex project into smaller tasks.
2) Organize tasks in a chronological order.
3) Estimates how long a project required.
4) Allow user to know what tasks are dependent on other tasks to be completed first.




All works have been assigned to team members.

We will follow this sechdule as much as we possibly can.

Team Member Roles

Findings and Recommendations

Appendix

Initial Ideas

1) Eliminate all the screws
2) Motorize the peeler
3) Lazer!!!
4) Tray to hold the peeler
5) Circular 1-step Blade
6) Better Appearance Design
7) Grow an apple that would automatically have the skin peel off by itself (after taking out from the fridge?)
8) Solution that would dissolve the skin (?)
9) Cut up the apple completely, and then filter out the skin, then reform it back to the shape of the apple
10) Freezing up the apple so the skin cracked
11) Have a mate to peel the apple for us
12) Container that holds the apple, you turn the handle bar, then it peel the apple
13) Centrifugal Force Apple Peeler
14) Separate the corer, blade and the slicer
15) Foldable peeler
16) Adjustable size peeler
17) Using scruber(?) to peel the skin instead
18) Glue, Clamp instead of suction cup
19) Part of the kitchen part
20) Rotate the blade instead of rotating the apple
21) Detachable blade? (combine the traditional peeler and the conventional one)
22) Scanner that detect the soft/rotten part of the apple
23) Automatic Super Fridge that peels every for you
24) Optimize peeling process such that only the skin is being taking off
25) New generation of apple!!! NO SKIN!!! WOHOOOOOO
26) Use fertilizer that is not harmful
27) Ultra sound to pulverize the skin
28) Sand paper instead of the blade! 
29) A sphere with sand paper in so when one spin the sphere it peels the skin off
30) Make the skin sweet so that you would love to eat the skin
31) Adjustable size of the body so you can fit different size of apple/ vegetables on it
32) Better grib
33) Greener Material to plastic, no rusting, easier to manufacture
