Concept Screening and Scoring

Concept Screening Matrix

Concept Scoring Matrix

 

 

Description of Criteria

Weight – The overall weight of the AEV. The goal is to minimize this while also keeping stability to improve the efficiency of the AEV.

Stability – The act of keeping the AEV stable and having it move in one solid direction to improve the efficiency.

Cost – How much the final AEV will cost, the goal is to minimize this criteria while also not jeopardizing the quality of the AEV.

Aerodynamics – The part of the AEV that minimizes the air resistance that will act against the AEV.

Appearance – The visual appeal of the AEV design. This includes the placement of components, the body design, and other aesthetic features.

 

 

Advantages and Disadvantages of Designs

Design A (Anthony)

  • Advantages: lightweight, efficient, least in cost,different approach with arm
  • Disadvantages: only one wheel, less aerodynamic

Design B (Joseph)

  • Advantages: lightweight, stable, placement with battery and Arduino
  • Disadvantages: high surface area

Design C (Trent)

  • Advantages: small, efficient, ramp on front for helping against air resistance
  • Disadvantages: maybe too heavy compared to some of the others, high cost, high surface area

Design D (Maxim)

  • Advantages: small, lightweight, efficient.
  • Disadvantages: front has a higher surface area; less aerodynamic.

Design E (Combined)

  • Advantages: aerodynamic, lightweight, efficient, good placement among battery and Arduino, moderate cost
  • Disadvantages: Arduino on bottom (must be careful)

 

 

 

 

Designs to be Continued

Design C and Design E will be carried forward in the design process. The designs were selected based on the Concept Scoring Matrix method. The key features of these designs are their low cost and low weight. Both of these designs are also somewhat aerodynamic.
