Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If electronic elements are mounted inside the lamp cap during assembly, then the LED lamp bulb can be manufactured, but a special locating device is needed which increases assembly difficulty and lowers production efficiency
Solution Approach 1:
The electronic elements are pre-mounted on the conducting wires before the final assembly into the lamp cap. This preliminary action allows the electronic elements to be positioned and secured in advance, eliminating the need for special locating devices during the final assembly process and significantly improving production efficiency
2Ease of manufacture
If electronic elements are mounted inside the lamp cap, then the LED lamp bulb can be manufactured, but the high cost of electronic elements increases the overall production cost
Solution Approach 1:
The electronic elements are integrated directly onto the conducting wires, merging the electronic component mounting function with the electrical connection function. This integration eliminates the need for separate mounting structures and reduces the overall bill of materials cost, thereby lowering production cost while maintaining manufacturing capability
