Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the function switch is designed on the back surface or side surface of the sensor, then the sensor can be installed in a lamp, but the function switch is surrounded by the lamp and requires rotation or disassembly to operate
Solution Approach 1:
The patent moves the function switch from the traditional back/side surface design to the front surface of the sensor, positioned between the Fresnel lens and the user. This dimensional repositioning allows the switch to be directly accessible without requiring rotation or disassembly, resolving the contradiction between ease of operation and device complexity.
Solution Approach 2:
The patent introduces a key component that bridges the user and the function switch. The key is installed on the Fresnel lens and connects to the function switch, serving as an intermediary mechanism that enables easy operation of the switch while maintaining a simple overall structure.
2Ease of operation
If the function switch is surrounded by the lamp shell, then the sensor can be installed in the lamp, but the lamp shell must be opened to expose the function switch
Solution Approach 1:
By repositioning the function switch to the front surface of the sensor rather than the back or side surfaces, the patent enables direct accessibility without requiring lamp shell disassembly. This dimensional change eliminates the need for complex installation procedures while maintaining ease of operation.
3Ease of operation
If the sensor requires rotation to expose the function switch, then the switch can be accessed, but the operation becomes troublesome and time-consuming
Solution Approach 1:
The patent eliminates the rotation operation by repositioning the function switch to the front surface, making it directly accessible to users. This dimensional repositioning removes the time-consuming rotation step while maintaining easy access to the function switch.
