Team Vision for System-Level Design Phase

Our Plan For This Phase

During the Systems-Level Design Phase, our goal as a team was to begin determining how to translate our customer & engineering requirements into practical design concepts. At the end of this phase, we hoped to have a solid baseline of tangible system ideas to build off of going into the Preliminary Detailed Design Phase.

What We Accomplished In This Phase

During this phase, our team was able to formulate a variety of different concepts in an attempt to satisfy the necessary functions we had previously defined for the product. The electrical side of our team conducted research on user feedback, inputs/outputs and possible switches/connectors to use, and also created flowcharts and block diagrams to conceptualize processes. The mechanical side of our team began to brainstorm methods to allocate more space for the electrical components of the car, as well as completed some initial modeling of the car's subsystems.

Feasibility

Our selected concept retains many of the elements from the original NXP car, while enhancing the areas identified in our customer and engineering requirements. The original car is proven in its ability to traverse the track but has shortcomings in the electrical and mechanical systems that make the iterative process of control system tuning and debugging inconvenient for users. We also aim to mitigate issues caused by unintentional overcurrent of the motor control board which caused PCB traces to vaporize.

Concept Development

No Suspension

No Suspension

Above shows a simplified concept of our ideal chassis with no rear suspension. This option would reduce weight and simplify the chassis assembly.

Rear Suspension

Rear Suspension

Above shows a simplified concept of our revision on the rear suspension. The Goal of this design is to create more space in the chassis for electrical components.

Plans for next phase

For the preliminary detailed design phase we will be deciding on the critical components for the drive system, control board and chassis, working on initial designs for board layout and chassis, and generating test plans to verify our designs against our requirements.
