Criteria Description:
Stability: The stability of the design is dependent on the weight distribution, which is important for the AEV to remain on the monorail for the duration of its movement.
Lightweight: A lightweight design is important for allowing for faster acceleration and deceleration of the AEV.
Cost: Low cost is vital for the design, or else it won’t ever be able to be implemented.
Fix-ability: The more simple and minimalist the AEV design is, the easier and less costly it will be to fix in case of breaking.
Aerodynamics: An aerodynamic design is important for allowing the AEV to move as quickly and efficiently as possible. This would reduce the amount of power needed to accelerate.
Pros and Cons of Each Design:
Cameron’s Design:
Pros and Cons:
The nosecone at the front of the AEV makes this design extremely aerodynamic, however, the added weight from some of the extra features makes this design fail in the weight category.
Cole’s Design:
Pros and Cons:
This design has a very aerodynamic front, and is balanced out to preform as max stabability. However, the complexity of this AEV forces a sharp decline in the categories such as fixability, weight, and cost.
Duncan’s Design:
Pros and Cons:
Duncans simple yet useful design ensures that the AEV preforms exceptionally well at being stable, lightweight, fixable, and cost efficient, however, the wide base comes at a cost to the preferred aerdynamic nature of the other AEV designs.
Emily’s Design:
Emily’s design is much more complex than the other designs. Because of all the features, this design performs exceptionally well at all categories except for cost.
Team Design:
The team design, while combining features from all three designs, matches the references vehicle in cost and fixability, but excels in all other categories.
Final Designs:
After the screening and scoring process, you can see that the group has two designs left they can choose from and continue working with. These two designs are Duncan’s design and Emily’s designs. These two designs passed the screening selection and scored the two highest scores on the scoring selection. These two designs focus on the lightweight features of AEV, along with being stable. They also will combine to focus more on one of the main focal categories: cost. These two designs will now be modified after testing, and will be converged into one final design.
