Here is the outline for all of the steps we took in our design process. We broke down the design process into various steps to fully represent how we came to our final prototype.

3. This is an investment opportunity to address a market need for a low cost water based game.
Nina
something about an investment opportunity capturing a market that’s been untapped

We recognized the investment opportunity in creating a low cost water based game. There are many expensive water games including the Flyboard Pro Series that’s pictured on the screen. This specific model sells for $5399

4. While children prefer entertainment, parents value safety of the game.

We first interviewed people of all age groups to narrow down our target audience. We found our target audience to be kids that are age 8-12 as well as their parents or guardians. After speaking to several kids under the age of 18, kids in the age range 8-12 were both capable of swimming and still being imaginative enough to have fun with the game. Most kids above 12 find little to no interest in such a game at that age. We created a detailed survey for kids and for their parents, and these are the results we found. Kids seemed to be more concerned with the entertainment factor while parents were mainly concerned with the safety of the product.

5. Stakeholders seem to have similar preferences regarding the requirements for the water game.
TOP STAKEHOLDERS
Dr. Thomas Colledge
Users and Consumers
Angel Investors
Table 1. Stakeholders
Nina
Dr Colledge has supervised us along the way and taught us the process to create our designs. Ultimately we are pitching our design process and prototype to him.
Users and Consumers are important because even if we create a good design, people must want to use it and buy it or else it is pointless
Furthermore, angel investors are an important stakeholder because we would not be able to get our design into production and into sales without the financial backing and support
We also surveyed these stakeholders along with our target audience to see what functionality preferences they valued most.
Other stakeholders that we had to take into consideration are ...
Garbage men/disposal crew
regulators of the game (follows UL game regulations)
makers of the game (low cost and not difficult to assemble)
sales person (made it as marketable as possible)
every person that has some stake in this
Write top 2 or 3 stakeholders
Mention “additional stakeholders which we took into account were…”

6. After evaluation of user requirements and constraints, specifications were formed to build a prototype.
Price
Must be less than $40
Safety
Must meet UL standards for children 8-12
Weight
Supports 90 pounds or less
Environmentally Sustainable
Must meet waste management standards
Durability
Remains intact after dropping from 2 feet 3 times

TALK ABOUT UL STANDARDS***
TALK ABOUT WASTE MANAGEMENT STANDARDS****
just say additional specs
elaborate must be safe in safety spec on slide. Use UL regulations
durability -- as measured by dropping from certain distance this many times

7. Entertainment was found to be the predominant specification to the stakeholders.

8. There are multiple designs that satisfy the problem statement.

9. We ranked each idea according to specific criteria in order to determine the best design.

10. The Ring Skis were found to be the best design after evaluating the specific criteria.

11. We calculated the buoyancy and found that our design does float with a 77 kg person.
Nina
First we calculated the downward force of a 77kg person and the raft.
We then calculated the depth that the raft would sink under the water if the person put all of their weight into one foot on one side of the raft.
To find the buoyancy force we first calculated the surface area and used it in the equation for the buoyant force.
We found that the buoyant force was larger than the downward force of the person and the raft, so ultimately our model would float.

12. The object of the game is to walk the treasure across the ocean!
Ricky
After the first half of the game described by the previous team, the participants make a handoff of the “treasure” they sorted in the first few minutes of the game to the member of the team who is going to then try to carry the “treasure” across the length of the pool where the game is taking place.
Describing the game, why is it going to be fun?
This is the big picture of the game

13. An important constraint was keeping the design under $40.

Ricky
The supplies we used for our prototype we chose specifically to satisfy the constraint assigned to us of producing it under $40. the materials we used in production were plywood, paracord. gorilla tape, a bucket and 5 inner tubes.

14. The prototype dimensions were designed to fit the desired age range.

16. Testing our prototype allows us to identify ways in which we can improve our model.
REVISIONS
Cover front and back edges of plywood with tape
Inflate inner tubes more
Adjust string length between feet
Reinforce design with tape
Table 6. Revisions
Ricky
A few last minute revisions we made demonstrated their necessity during our test run, where the tubes sank a little more than anticipated so we decided to fill them each with more air. we also decided to use more tape in order to increase durability and make it safer by removing some of the edges. also we decided to decrease the amount of paracord between the feet to help increase the stability.

17. We have created a fun and safe game that targets an untapped market for low cost water games.
Mario
what’s good about this? Its fun, cost effective, how to sell it

18. The project tasks were distributed among group members based off of our time constraint.
