Preliminary Design


Figure 1: Concept Sketch Design A

Explanation: The concept behind this design was to have high stability. All the parts were designed to be in a line to maintain as much stability as possible.

Pros: Very stable, which would limit rolling resistance. This would allow more efficiency, therefore reducing wasted energy.

Cons: Has aerodynamic blockage, causing more air resistance. The vehicle is also not safe due to the wing being higher up on the vehicle.

 

 

 

Figure 2: Design Concept Sketch B

Explanation: This design was created to have minimal air resistance while also being safe. The design is also balanced to allow for a stable foundation.

Pros: Has minimal aerodynamic blockage, has structural integrity, and safety is a high priority.

Cons: There are concerns with the vehicle maintaining stability. Concerns include placement of parts, such as the Arduino, which would cause it to incline to one side or the other based on orientation on the track.

 

 

 

Figure 3: Design Concept Sketch C

Explanation: This design was intended to be structurally stable, as well as having low maintenance. It also emphasized durability and simplicity.

Pros: The design is highly stable, easy to maintain, durable, and safety is a high priority.

Cons: The design does not have outstanding issues, although it is not the most aerodynamic.

 

 

 

 

Figure 4: Design Concept Sketch D

Explanation: This design was created to be practical, easy to use, and maintain. Research and development will be less complex with these aspects.

Pros: This design has low maintenance, high durability, and safety along with practicality.

Cons: Like design C, design D didn’t have any outstanding issues. However, the amount of drag created could compromise the efficiency and energy conservation.

 

 

Figure 5: Design Concept Sketch E

Explanation: This design was intended to be aerodynamic, to reduce air resistance, and be safe. The design was also intended to be highly stable.

Pros: This design has an aerodynamic shape, which creates minimal air resistance. This design also takes safety into high consideration.

Cons: Unlike most of the other designs, there is considerable maintenance. Since the Arduino could not be accessed without the removal of one wing, this consumed a lot of time, especially if used in Advanced R&D and Performance Tests. The stability of the vehicle was also poor, as there is a lack of proper balancing.
