Criteria & Constraints - List or reference the specified Criteria and Constraints you're designing for. List at least one implied criteria. List at least three implied contsraints.
Criteria
• Build a watercraft that allows you to traverse the CHS swimming pool.
• Protect your workspace from damage!
Implied: get your boat to float.
Constraints
• 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: fit through the door. You boat must becovered in ductape. You can only use carboard and ductape.
Define the Problem and Brainstorm Solutions - State the problem you are designing a solution for. List at least 20 ideas you have regarding your solution.
- Tape everything
- Wight name on boat
- Make corners better
- Use stiff carboard on base
- Use flimsy on walls
- Make a strong bow
- Put the fatter part at the back
- Make front thinner than back
- Make it big enough for 2 people
- Make shure the walls dont give in
- American flag
- Stiff Carboard
- Ores
- Harness on swimmers
- Fat bottom
- Mermaid
- Stiff carboard
- Ductape rope
- Yubes in front and back
- Hook tubes to bow and stern
- Large amount of surface to distribute weight
- Hydrodynamic
Sketch Ideas
Prototype Ideas - Craft physical prototypes (models) of each of your three sketches. Use a notecard or post it note to call out at least one key feature on each model. Post the images to your blog and describe the key feature that you've pointed out on each.

Select an Approach - Generate feedback (+, change, ?, !) and make a decision matrix regarding your sketches/prototypes. Specify the approach you've chosen and justify your selection.
We did number 2.
Design 1 ( Ruy ) 8 6 9 23
Design 2 ( Mike ) 10 0 10 16
Design 3 ( Staney/ 10 6 10 26
Armoundo)
Test Achievements:
• The Longest - Awarded to the team with the watercraft that floats the longest (multiple teams may be awarded this achievement if multiple boats remain afloat at the end of our competition period). - Build your watercraft. Document it with a presentable photo.
Reflection Achievements:
• Feedback - Generate ten items of feedback for your effort (from the design/build process and/or the actual product). Make sure you include at least one item of feedaback in each of our four feedback areas (+, change, ?, !)
•• Redesign - The same boat. Iwould get better swimmers though.
• Massive Cargo- Have 3 peope in you boat and not sink.
Nice job sharing your design/build experience. You're the first student to actually "claim" your achievements! Very helpful for me to verify rather than count (I always miss one or two that way).
ReplyDeleteGood job calling out the features on your prototype models.
I like your achievement, I may add that to the mix next time... especially if I explicitly limit the materials. That would creat a neat "competing" demands situation which would require some solid strategic choice making.
Thank you Mr. Olson. That would make this challange more interesting.
