Concept Screening
Table 1: Concept Screening Spreadsheet
This matrix shows the groups criteria efficiency, weight, cost, stability, and design. Efficiency is how well the AEV is expected to move up and down the track. The weight is just how much the AEV is expected to weigh that’s not to heavy and not too light. The cost is just the overall cost of the AEV based on the cost of each part the design has in it. The stability is just how stable the design will be on the track and its overall balance. The design is the overall appeal and effectiveness in placement of the Arduino and motors with the body of the AEV
Concept Scoring
Table 2: Concept Scoring Spreadsheet
Michael’s Design:
My AEV design scored above average compared to the sample AEV. This was something that was aimed for was less weight to maximize efficiency. That is exactly how the scoring ended up in the concept screening and scoring. Due to the fact I included the back side wings my concept wasn’t the cheapest or lightest, but I believe it was important for balance and security of the Arduino. I feel confident after these matrices moving forward with this design and finding more ways to improve it. I am hoping that the object will have enough weight to it to move efficiently down the track and this is something that will be studied going forward.
Ryan’s Design:
This AEV design was rated about the same as the sample AEV. Its scores, however, varied in both the efficiency and weight categories. The cone on the front of the AEV improved efficiency but also increased both the weight and cost. While the design had some improvements, it did not make the final cut to continue development.
Bob’s Design:
Initially in concept screening my design was average. As my design was catered more towards luxury and stability than speed or efficiency the weight and cost of the AEV would be more than other proposed concepts. Afterwards, in the concept scoring process my design performed poorly as the team was more heavily concerned about efficiency cost and stability, of which only stability my design performed well. As of now the luxury AEV design will be tabled until the needs of the project change more towards stability and design more than efficiency and cost.
Jack’s Design:
My design performed well in both screening and scoring matrices, having the most points in both. I designed it to be as simple as possible. It is symmetric, light, and only uses one piece of plastic driving its costs down. I am worried that my design is too light and won’t be able to go full speed safely. As a group we feel confident with this being one of the design that we will continue with and attempt to develop.
