Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If different special collection terminals are used for different motion modes, then measurement precision for specific motion types is improved, but device complexity and ease of operation deteriorate due to needing multiple devices
Solution Approach 1:
The collector is designed with a universal interface that can detect multiple types of motion signals through the same detection pin group. By establishing correspondence relationships between different detection signals and motion types, a single collector can perform multiple motion detection functions, eliminating the need for multiple specialized terminals.
Solution Approach 2:
The detection system is segmented into modular components: the fixed portion with probe groups and the movable collector with detection pin group. This segmentation allows the collector to be universally applied to different motion scenarios while maintaining specialized detection capabilities through signal correspondence relationships.
2Measurement precision
If different special collection terminals are used for different motion modes, then measurement precision for specific motion types is improved, but ease of operation deteriorates due to needing multiple devices
Solution Approach 1:
The collector serves as a universal motion detection terminal that can be used across different motion modes. The processor automatically determines motion types by matching detection signals with pre-established correspondence relationships, making the device easy to operate without requiring users to switch between multiple specialized terminals.
3Adaptability or versatility
If a single collector is used for multiple motion modes, then adaptability is improved, but measurement precision may deteriorate due to general-purpose design
Solution Approach 1:
While the collector has a universal structure, the detection system achieves specialized precision through local signal processing. The processor applies specific correspondence relationships for different motion types, ensuring high measurement precision for each specific motion mode while maintaining overall adaptability across multiple scenarios.
