Concept Screening And Scoring

Concept Scoring

 

Concept Screening

Description of Criteria

  • Stability: keeping the AEV parts stable
  • Blockage: making movements of parts impossible
  • Maintenance: ability to withhold the parts without breaking
  • Durability: security to withhold pressure
  • Safety: secure parts to protect against any problems
  • Weight: overall weight of all parts of AEV
  • Cost: overall cost of all parts of AEV
  • Aerodynamics: minimizing air resistance acting on AEV

Abbie’s Design

Abbie’s AEV design had a small bottom which is less surface area which means less weight so it will be easier to move on the track. This design scored a yes on the concept scoring but a no on the screening. The group’s decision was to keep this design and build off of some of these ideas with the cars that tested later in the lab.

Ellie’s Design

Ellie’s design had propellers on the back and front in hopes to make the car move more efficiently. Being on the safe side, the group decided this wasn’t a good idea since the Arduino board couldn’t be placed on one side or the other fearing that one of the propellers would hit it. Also she had a flat base to eliminate wind drag. Ellie’s design scored a no on both tests so an executive decision was made to not go on with this design.

Jacob’s Design

Jacob’s AEV design had a curve in the front of the car which will make it more aerodynamic. He also added angled walls around both the battery and Arduino board to reduce air resistance.  This design scored a yes on both tests so it will continue and be built off of like Abbie’s design for in the future.

Erin’s Design

Erin’s design had some of Jacob’s and Abbie’s thoughts into one design. She thought to put the curve on the front and back to make it move efficiently in both directions. Also she had the smallest design which would eliminate some weight from the car as well as making it cost less to produce. Erin’s design scored a no from the concept scoring but a yes on the screening. The group decided to continue in the making of this design.

Final Decision

We decided to continue with parts of Abbie, Jacob, and Erin’s designs of the AEV. Once we were done in this lab, we put ideas from each car together and agreed on one AEV that had many different aspects that were similar in all of the individual AEV sketches.
