Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If separate circuit boards are used for radar antenna and controller with a base plate between them, then the system structure is stable, but the number of components increases, cost increases, and size increases
Solution Approach 1:
The patent combines the radar antenna circuit board and controller circuit board into a single integrated circuit board. The antenna module and controller module are mounted on opposite sides of the same board, eliminating the need for separate boards and base plates. This merging reduces the total number of components while maintaining structural stability through the unified board design.
2Adaptability or versatility
If separate circuit boards are used for radar antenna and controller, then component placement is flexible, but manufacturing difficulty increases and cost increases
Solution Approach 1:
By integrating both the antenna module and controller module onto a single circuit board, the patent simplifies the manufacturing process. Instead of assembling multiple separate boards and base plates, the integrated board can be manufactured as a single unit with pre-positioned mounting areas, reducing assembly steps and manufacturing complexity while maintaining component placement flexibility.
3Reliability
If electronic components are mounted on circuit boards, then the radar system functions properly, but heat is generated that reduces reliability and durability
Solution Approach 1:
The patent extracts the heat dissipation function from the traditional enclosed circuit board structure by providing a recessed space within the housing that exposes the circuit board to the external environment. This allows heat generated by electronic components to be dissipated more effectively to the surroundings, reducing temperature buildup and improving reliability.
Solution Approach 2:
The patent changes the thermal parameter of the system by modifying the housing structure to include a recessed space that increases the surface area exposed to ambient air. This structural parameter change enhances heat dissipation capability, allowing the system to operate at lower temperatures and improving overall reliability and durability.
4Adaptability or versatility
If multiple separate components are used in the radar system, then functional requirements are met, but the overall size of the system increases
Solution Approach 1:
The patent merges multiple functional components into a compact integrated assembly. The antenna module, controller module, and housing are integrated into a single unit with reduced overall dimensions. By eliminating separate base plates and stacking components vertically on opposite sides of the circuit board, the system achieves full functional capability in a smaller volume.
