Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a robust framework is used to support sensors and withstand environmental conditions, then reliability and stability are improved, but device complexity and weight increase
Solution Approach 1:
The framework is divided into modular components including a base structure, housing, duct system, and mounting mechanisms. This segmentation allows each component to be optimized independently for strength and stability while simplifying the overall assembly and maintenance process.
Solution Approach 2:
The framework is designed with universal mounting interfaces and standardized connection points that can accommodate various sensor types and configurations. This multi-functionality reduces the need for custom fabrication while maintaining structural integrity and reliability.
2Measurement precision
If alignment mechanisms are added to optimize sensor positioning, then measurement precision is improved, but device complexity increases
Solution Approach 1:
Alignment features such as precision-machined mounting surfaces, locator pins, and pre-positioned sensors are incorporated into the framework design before final assembly. This preliminary action ensures accurate sensor positioning is achieved through the manufacturing process itself, eliminating the need for complex post-installation alignment mechanisms.
3Adaptability or versatility
If multiple sensor types are supported in the assembly, then adaptability is improved, but device complexity and manufacturing difficulty increase
Solution Approach 1:
The framework employs universal mounting interfaces, standardized electrical connections, and modular sensor housings that can accommodate various sensor types including LIDAR, cameras, and radar. This standardization allows different sensor configurations to be produced using the same base framework, significantly simplifying manufacturing while maintaining high adaptability.
