Our investigative processes include testing of two types of water guns, the Saturator Ak-47 and the Banzai Color Stream Blaster Water Gun. We wanted to understand the difference between the pressurize water gun (Banzai) and the motorized gun (Saturator). 
Overall, the Saturator AK-47 Water Gun performs at the average standard for toy water guns. While the water container or clip stays in place, the gun needs to be refilled very often during play.

Stakeholders

The primary stakeholders for the product are the user, the consumer, retailer, manufacturer, and shipping/transportation of the product.

Consumer

With relation to the Saturator water gun, there are two major consumers: adult (i.e parents) and the users -children and young adults. The needs and requirements of these two consumers are drastically different as shown below.

Buyer (Adults): Consumers are adults including young adults but our primary consumers are parents. Parents of the user will monitor the use of the product and their concerns will mainly be with safety. The needs of the adults are listed below:

  • Low cost
  • Safe
  • Easy for child to use & store
  • Durable
  • Long product lifespan
  • Non-threatening
  • Non-toxic

User (Children): The users of the product are children and this categorey also include and are not limited to children over the age of 16. For the primary user the product needs are:

  • Visually attractive
  • Fun to play with
  • Long range of shooting
  • Quick & easy to refill
  • Accurate & precise shooting
  • Lightweight
  • Easy to operate

Retailer

Retailers: Retailers are also stakeholders of the product. Their needs are as follows:

  • Satisfying to customer
  • Easy to shelve and store
  • Easy to sell
  • Durable

Manufacturer

Manufacturers: Manufacturers as stakeholders of the product have needs including but not limited to:

  • Few parts & materials
  • Minimize manufacturing processes
  • Efficient assemble process
  • Low cost production
  • Standard parts across a range of models

Shipping/Transport

  • Easy to stack
  • Small & lightweight product
  • Durable

Usage

How It's Used

When initially removed from the packaging, the Saturator requires 4 AA batteries for operation (batteries not included). The batteries are inserted through the butt of the water gun. After battery insertion, the Saturator needs to be filled with water before it can be used. This process is described in the image below.

User Studies

Our investigative processes include testing of two types of water guns, the Saturator Ak-47 and the Banzai Color Stream Blaster Water Gun. We wanted to understand the difference between the pressurize water gun (Banzai) and the motorized gun (Saturator).

Overall, the Saturator AK-47 Water Gun performs at the average standard for toy water guns. While the water container or clip stays in place, the gun needs to be refilled very often during play. Another negative aspect of this product is the range of shooting. Although it is advertised as a gun that can shoot over 25 feet, the stream of water barely makes it a distance of 15 feet.

In comparison to the Banzai Color Stream Blaster Water Gun, the Saturator is lighter and easier to maneuver.....
