Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the induction sensor and induction LED lamp are arranged on separate mounting seats, then the induction lamp can be assembled, but the structure becomes complicated and aesthetics are degraded
Solution Approach 1:
The patent merges the sensor mounting seat and LED lamp mounting seat into a single integrated mounting structure. The sensor is mounted on the same PCB board as the LED lamp, eliminating the need for separate mounting seats. This integration simplifies the overall structure, reduces the number of components, and improves aesthetics while maintaining assembly feasibility.
2Ease of manufacture
If the induction sensor is arranged on a different plane from the induction LED lamp, then separate mounting is possible, but the connecting location becomes irregular affecting appearance and mounting angle accuracy
Solution Approach 1:
The patent positions both the induction sensor and induction LED lamp on the same plane, specifically on the same PCB board. This arrangement ensures that the connecting location is flat and regular, improving appearance and ensuring accurate mounting angles. The integrated PCB mounting structure eliminates the problems associated with multi-plane arrangements.
3Ease of manufacture
If the outer surface of the sensor shield is directly connected to the light guide plate, then assembly is simple, but the appearance is degraded and induction accuracy is reduced
Solution Approach 1:
The patent designs the outer surface of the sensor shield to be smoothly connected to the outer surface of the light guide plate, forming a curved surface. This curved transition improves appearance quality by creating a seamless, aesthetically pleasing interface. The curved design also helps maintain uniform light distribution and does not interfere with the induction sensor's detection accuracy.
4Ease of manufacture
If the sensor shield has a flat inner surface, then manufacturing is simple, but the induction detection of moving human bodies is inaccurate
Solution Approach 1:
The patent applies different surface qualities to different regions of the sensor shield. The outer surface maintains a smooth curved shape for aesthetic purposes, while the inner surface facing the induction sensor is designed with concave and convex textures. This textured inner surface improves the induction detection of moving human bodies by enhancing the sensor's ability to detect infrared radiation patterns, while the smooth outer surface maintains appearance quality.
