Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If LED filaments are installed in the bulb shell directly, then the assembly process is simple, but the stability of LED filaments is poor and heat dissipation is insufficient
Solution Approach 1:
The patent introduces a template as an intermediary component between the LED filament and the bulb shell. The template provides a stable mounting structure with positioning holes and adhesive areas, ensuring the LED filament is firmly fixed while maintaining simple assembly process. The template acts as a mediator that resolves the conflict between simple assembly and stable fixation.
2Device complexity
If LED filaments are installed in the bulb shell directly, then the device structure is simple, but heat dissipation capability is insufficient
Solution Approach 1:
The template serves as a heat dissipation intermediary, conducting heat away from the LED filament through its material properties and structural design. The template's connection to the bulb shell creates a heat dissipation pathway without significantly increasing device complexity.
3Ease of manufacture
If traditional LED filament materials and specifications are used, then the production cost is high, but the lifespan and heat dissipation are insufficient
Solution Approach 1:
The patent changes the mounting parameters and structural configuration of LED filaments through the template design, improving heat dissipation and stability without requiring expensive material changes. This approach extends LED filament lifespan while maintaining cost-effectiveness.
4Ease of manufacture
If the assembly way of LED filaments is fixed, then the manufacturing process is simple, but the adaptability to different lighting types is poor
Solution Approach 1:
The template is designed with universal characteristics, featuring multiple positioning holes and adaptable structural configurations that can accommodate different LED filament types and lighting configurations. This multi-functional design allows the same template to serve various lighting types while maintaining simple manufacturing processes.
