Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a fan is provided inside the lamp to cool the light emitting body, then heat dissipation is improved, but the manufacturing complexity and assembly difficulty increase
Solution Approach 1:
The light emitting body is segmented into multiple LED substrates (first LED substrate, second LED substrate, third LED substrate, fourth LED substrate) arranged in a cylindrical configuration. Each substrate is independently mounted on the assembling stand with specific orientations, allowing modular manufacturing and assembly while maintaining effective heat dissipation through the fan.
2Strength
If welding is used for assembly, then structural strength is improved, but assembly convenience deteriorates
Solution Approach 1:
The patent replaces the welding process with a mechanical mounting system. LED substrates are fixed to the assembling stand using mounting structures that provide structural strength without requiring welding operations. This substitution maintains assembly convenience while ensuring the structural integrity of the light emitting body.
