Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If ultrasonic sealing is used to fix the lamp holder, then the fixing strength is improved, but the manufacturing complexity and cost increase
Solution Approach 1:
The patent combines the fixing function and sealing function into a single integrated structure. The lamp holder uses a unified component design where the fixing mechanism and waterproof sealing are achieved through the same structural elements, eliminating the need for separate ultrasonic sealing processes and reducing manufacturing complexity while maintaining fixing strength.
Solution Approach 2:
The patent replaces the ultrasonic sealing process with a mechanical sealing structure. Instead of using ultrasonic vibration to create seals, the design employs mechanical features such as interference fits, snap-fit connections, and integrated gasket structures that achieve both fixing and sealing through mechanical means, thereby simplifying the manufacturing process.
2Device complexity
If traditional screw fixing is used, then the manufacturing complexity is reduced, but the waterproofing performance deteriorates
Solution Approach 1:
The patent merges the fixing and sealing functions into a single integrated mechanism. The lamp holder design uses a unified structure where the same components that provide mechanical fixing also create the waterproof seal, eliminating gaps and crevices where water could penetrate while maintaining manufacturing simplicity.
Solution Approach 2:
The patent incorporates flexible sealing elements such as rubber gaskets or elastomeric rings within the lamp holder structure. These flexible components conform to mating surfaces and create effective waterproof seals while allowing for simple assembly and disassembly, achieving both waterproofing and ease of manufacture.
3Device complexity
If the lamp holder is exposed at the pin connection area, then the assembly is simplified, but the electrical safety deteriorates due to electric shock risk
Solution Approach 1:
The patent uses a nested structure where an inner insulating component is placed within the outer lamp holder body. The insulating element is nested inside the exposed area near the pin connection, providing electrical isolation without adding external complexity to the assembly process.
Solution Approach 2:
The patent introduces an insulating material or insulating component as an intermediary between the conductive parts and the exposed external environment. This insulating mediator prevents direct contact with conductive elements while maintaining the simplicity of the overall assembly structure.
4Ease of manufacture
If conventional lamp holder design is used, then the manufacturing cost is reduced, but the waterproofing and safety features are insufficient
Solution Approach 1:
The patent combines multiple functions (fixing, sealing, and safety protection) into a single integrated lamp holder design. By merging these functions into one component rather than using separate parts, the manufacturing cost is reduced while achieving improved waterproofing and electrical safety performance simultaneously.
Solution Approach 2:
The patent designs the lamp holder as a multi-functional component that performs fixing, sealing, and electrical insulation functions all in one structure. This universal design approach eliminates the need for multiple separate components, reducing manufacturing complexity and cost while enhancing overall reliability and safety.
