Weekly Report 2/2/18

This week we met to actually order some parts. We ordered the floor pump, inflatable seat for bladder, and the hand/foot pump from online. We tried to order everything else as well but the shipping was roughly an extra $10, so we are going to the store this weekend, probably Saturday, to get the rest such as tubing, rubber, and valves. We also updated our website with the last 3 weekly updates, the last presentation, and a few tweaks to our scope from the last paper.

Additionally, we came up with an outline for our verification plan. It is below:

Spec: size

Verification: measure with ruler

Spec: weight

Verification: measure with scale

Spec: ease of use

Verification: ask random people to use prototype with a set of instructions; at least 90% of individuals must be able to use the prototype without asking any questions

Spec: material stress/strain

Verification: place 182 kg onto the system and see how long it lasts. Weights will be used from the weight room

Spec: material cost

Verification: look up prices for individual pieces/materials that were used in the prototype and sum the total cost

Spec: fabrication time

Verification: call industry professional for quote

Spec: material flex

Verification: use a ruler to measure flex while the system is under stress/strain of 182 kg

Spec: test time

Verification: place stress/strain onto system for 26 continuous hours and re-measure all specifications

Spec: storage

Verification: use a ruler to measure prototype in its smallest/compressed state

Spec: adjustability

Verification: test prototype on a variety of car types

Spec: operation time

Verification: time the random users mentioned previously; also time ourselves when using prototype

Spec: user stress/strain

Verification: Use Widder’s lab to get EMG recordings of quadriceps during STS with and without our device
