Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If wireless electric radar detection or optical radar detection is used for spatial environment information acquisition, then detection range and power can be sufficient, but device complexity and cost increase significantly, making them unsuitable for typical IoT devices with limited power and simple application scenarios
Solution Approach 1:
The patent combines sonar detection functionality with IoT device integration, merging the detection system into the IoT device structure. This allows the IoT device to perform spatial environment detection without requiring separate complex radar systems, thus reducing device complexity while maintaining adequate detection capability through the integrated sonar module
Solution Approach 2:
The patent replaces electromagnetic-based detection systems (wireless electric radar and optical radar) with acoustic-based sonar detection. This substitution uses sound wave propagation and reflection principles instead of electromagnetic waves, enabling spatial detection with simpler hardware suitable for IoT devices while operating effectively in various media environments
2Adaptability or versatility
If sonar sensor modules are integrated into IoT devices for spatial detection, then adaptability to various media and device complexity are reduced, but detection range and signal processing capability may be limited
Solution Approach 1:
The patent employs multiple sonar sensor modules arranged in different spatial directions to segment the detection space. This segmentation approach enables comprehensive coverage of the spatial environment while maintaining individual module simplicity. The distributed arrangement of multiple modules extends the overall detection range beyond what a single module could achieve
Solution Approach 2:
The sonar sensor module is designed with universal applicability across different media environments (gas, liquid, etc.). The same basic sonar principle of sound wave emission and reception works across various media, providing multi-functional adaptability without requiring media-specific detection systems, thus achieving versatility while keeping individual modules compact
