Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If cables with conductors are used to conduct electrical energy through the base, then electrical connection is achieved, but assembly complexity increases and manual assembly is required
Solution Approach 1:
The patent extracts the cable from the system by establishing direct electrical connections between the circuit board and base contact pins, eliminating the intermediate cable component and simplifying the assembly process while maintaining reliable electrical connection
Solution Approach 2:
The base is divided into separate functional parts (fixing part and connecting part) that can be assembled independently, with the circuit board directly connected to the base, eliminating the need for complex cable routing and folding operations
2Reliability
If cables are folded into the housing after soldering, then electrical connection is established, but installation space increases
Solution Approach 1:
The cable is completely removed from the system by establishing direct solder connections between the circuit board and base contact pins, eliminating the space that would otherwise be occupied by folded cables in the housing
Solution Approach 2:
The electrical connection function is merged directly into the base structure through contact pins that connect the circuit board to the lamp socket, eliminating the separate cable component and reducing installation space
3Reliability
If manual assembly is used to handle and fold cables, then electrical connection is achieved, but assembly cost increases
Solution Approach 1:
The cable handling operation is extracted from the assembly process by establishing direct connections between the circuit board and base, eliminating the need for manual cable folding and reducing assembly cost
Solution Approach 2:
The manual mechanical operation of cable folding and positioning is replaced by a simplified assembly process where the circuit board is directly soldered to the base contact pins, which can be more easily automated
