156B Week 5

Overview of Status of Analysis, Design, Fabrication, Tests, etc.

Accomplishments from Previous Week

● Combination materials testing (Garrett and Miles)

● Waterlogged testing (Garrett)

● Composite sole (Garrett and Miles)

● Field Testing select materials (Garrett and Jordan)

● Making water sock with zipper and strap (Ho)

● Field Testing two different water socks (Ho)

Goals for Next Week (list names after each item). Use specific and measurable objectives.

● Field test insole and determine better manufacturing process (All)

● Keep brainstorming the outer material for the water sock (All)

● Testing insole prototype with water sock (Jordan)

● Finding an alternative to hot glue (All)

● To make a water sock for Jordan to test (Ho)

● Find shorter length zippers (Jordan and Ho)

Sponsor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)

● The zipper and velcro methods seem to be very viable for the design

● Continue testing, a wider range or ideas is best

● Even though prototyping is moving forward, don’t forget that a cobbler is still an unused resource

Instructor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)

● In reference to our insole prototype:

○ Try replacing hot glue with silicone

○ Contact Tom/Ian or other labs about teflon

○ Try different durometers of Urethane. They can be easily mix and poured

○ A mold could be created for quicker repetitive prototyping

○ Putting silicone/etc under a vacuum will ensure no bubbles, but for a quick prototype bubble may not matter too much

● The overall design might want to float or have neutral density, so as to not weigh the user down too much

Risks and Areas of Concern

● Reducing drag

● Ability to be taken on/off
