The 2nd Annual Cardboard Canoe Challenge!

OUR TEAM EARNED ELEVEN ACHEIVEMENTS TOTAL
DESIGN ACHIEVEMENTS Define and Brainstorm the Design:
We need to create a boat made of completely cardboard and duct tape that will float in a body of water.
Brainstormed Ideas: Flat bottom, longer length, high walls, low walls, shorter length, v-shaped bottom, pointed front, angled front, pointed back, flat back, completely covered in duct tape, duct tape only covering cardboard exposed to water, wide bottom, narrow bottom, oars, pull with a rope, push with swimmers, paddle by yourself, one person in boat, two people in boat, lay down flat, sit up on butt, kneel in boat, stand in boat
Big Brain: I think I had the most brainstorm ideas WRITTEN DOWN; however, our whole team contributed to the entire brainstorm list
Criteria:

- Build a watercraft that allows you to traverse the CHS swimming pool.

- Your "boat" must float at least one student through the course of the competition.

- Protect your workspace from damage!

- Implied: Keep your workspace clean

Constraints:
- You may only use Cardboard and Duct Tape for this event.
- All Staples or other foreign material must be removed from your cardboard. If we trash the pool, we will not be invited back for other activities during the year (yes, we have other activities in mind for 2nd semester).
- Cardboard must meet our quality standard and be approved by the instructor (more info to follow)
- Each boat must have a minimum of a 3" tall "sidewall" (no completely flat designs).
- All exposed cardboard must be covered in duct tape (this will reduce cardboard disintigration in the pool).
- Each team will be provided one "versa table" cardboard box piece and two 60yrd rolls of duct tape. Any materials beyond this (likely need more cardboard) need to be resourced by your team.
- Implied: The boat must fit out of the doorway
- Implied: The boat must be able to be transported from the classroom to the pool
- Implied: The boat can not pose any threat to the students in or around the boat while it is in the water

PROTOTYPES:

First Prototype:

- Flat Bottom

- Curved, pointed bow

- High Walls

Second Prototype:

- V-Shaped Bottom

- High Walls

- Short Length

Third (Final) Prototype:

- Flat Bottom

- Not so high of walls (easier paddling?)
- Rectangle with a pointed front (stable)
DESIGN SELECTION:
First Idea:
+ - flat bottom for stability
Change - High walls
? - What is the optimal boat length?
! - Shorten the walls and make it longer
Second Idea:
+ - V bottom for straightness
Change - High Walls
? - Should a flat bottom or v shaped bottom be used?
! - Use a flat bottom and shorten the walls and make it longer
Final Idea:
+ - Flat bottom and optimal length
Change - Final Idea- no need for a change
? - How should we propel the boat? (pulling or paddling)
! - Pulling could be faster and easier for the pilot to keep the boat stable
MATRIX:
First: short, high walls, flat bottom, one point in front, curved bow
Second: short, high walls, curved bottom, two points, looks a lot like a regular canoe
Third: longer (optimal lengthe between speed and handling), shorter walls, flat bottom, one point in front, point is slightly curved
We will use the third and final prototype for our cardboard boat.

The Deep Dive

1. “From the buildings in which we live and work, to the cars we drive, or the knives and forks with which we eat, everything we use was designed to create some sort of marriage between form and function.”

2. The folks at IDEO state that they are not experts in any given area. But, they do claim to be experts on the "They are the experts on the process to design stuff", which they apply to the innovation of consumer products.

3. After the team of designers is brought together, told the problem, and informed they have five days to “pull it off,” what phase of the design process do they immediately engage in?
The team splits into groups to brainstorm.

4. Give two examples of what the team members did during this phase.

a. The split into different groups and took pictures of shopping carts.

b. They asked questions with experts and users of shopping carts and the builders of them for details.

5. List five rules-of-thumb that IDEO employees follow when they share ideas during the brainstorming phase:

a. One conversation at a time

b. Stay focused on topic

c. Encourage wild ideas

d. Defer judgement

e. Encourage ideas of others

6. Why should wild (and sometimes crazy) ideas be entertained during the brainstorming phase?
It could give other people ideas and show another side of ideas. The wild idea could also maybe work. If they think about it, maybe this idea could work the best.
7. After the brainstorming phase was over, the team narrowed down the hundreds of ideas by using sticky notes for those ideas that were not only “cool” but also build able in a short period of time. What phase of the design process is this called?

8. IDEO believes that the ideas and efforts of a group will always be more successful than the planning of a lone genius.

9. Once the ideas were narrowed down and divided into categories, the group was split into four smaller teams. What phase(s) of the design process was each of these groups responsible for?
Model and build a prototype
10. The leaders at IDEO believe that playful behavior and a fun environment are two important reasons why their employees are able to think quickly and creatively to produce innovative results.

11. Sometimes, people come up with great solutions that work by trying their ideas first, and asking for opinions later.

12. Design is often a process of going too far and having to take a few steps back. What phase of the design process would the critique of the four mock-ups come under?
Refining and communicating results
13. Upon critique of the four teams’ models, it was obvious that none of the teams had developed an optimum solution. However, the people at IDEO believe that it is important to fail often in order to succeed sooner.

14. What percentage of the entire week’s time did it take to fabricate the final prototype?
About 14% of the week's time
15. Instead of showering his design team with a tremendous amount of praise, what did the boss require his employees to do with their new design?
Improve it
16. Of all the things that we are surrounded by every day, what has not been placed through the design process?
Nature
Conclusion

1. What did you find to be the most impressive part of the team’s effort?
It was interesting to watch the teams break off into groups and researched different aspects of the project at hand. This way they could accomplish multiple parts of research at one time.
2. What advantages are there to having a design team with members that have non-engineering backgrounds?
They all have different specialties so they can each contribute differently to the cause.
3. There was a point in the process where a self-appointed group of adults stepped up, stopped the ideas, and redirected the group to break up into teams. Why was this done?
They did this so they could get more research and ideas in a more timely fashion. This could also give the team the option to focus more on the smaller parts of the project.
4. At the end of the video, Dave Kelly states, “Look around. The only things that are not designed are the things we find in nature.” Can you think of anything that would contradict this statement?
Rivers are designed by nature to allow direct flow of water in the direction of gravity.

$150 Duct Tape

This was a killer price for this much Duct Tape (about half of what it would be anywhere else):

(A very helpful Costcoer that saved the day for the 2nd Annual CHS Cardboard Canoe Challenge)

I had been to the Costco on Morena with no luck on finding tape. I followed up at the Business Costco in Kearny Mesa to find this good price. It's important to me to be a good steward of our Engineering Lab Donation fund.

I nearly missed the tape in the Kearny Mesa store and have a good story regarding the importance of communication and an outgoing demeanor for anyone that's interested in hearing it.

? - Why is Duct Tape called "Duct Tape"? What is the purpose for which the tape is named?
It is called "Duct Tape" because it is used to close ducts in which fluid, air, or other substances pass through. This tape is highly water resistant and strong so it does its job well at sealing air/fluid/electricity ducts.

Design/Build

Jason and Joe make progress on their cardboard canoe build:


Meanwhile, Putnam and John make progress on testing a prototype:










































? - Even though this team is already under way with the construction of their boat, how might the prototype support the construction of their project?

It can show what works on the boat and what the flaws are that can be improved.
? - How effective does their model appear to be? What useful information might the team discover with their test?

The model was not a scale model but it had some of the general characteristics such as a longer length, a pointed bow, and a flat bottom. With the test we can find what will work well and achieve the goals of the craft and what needs to be changed to meet our goals.
