Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a light emitting device has only two power feeding parts for LED, then the structure is simple, but it cannot accommodate additional components requiring electrodes
Solution Approach 1:
The holder is designed to serve multiple functions: it provides mechanical support for the light emitting device, acts as a heat dissipation structure through the heat dissipating plate, and provides electrical connections through multiple terminals. This multi-functional design allows the single component to accommodate not only the LED but also additional components like photodiodes and thermistors without requiring separate mounting structures.
2Adaptability or versatility
If multiple components are mounted on the light emitting device, then functionality is enhanced, but the device size increases
Solution Approach 1:
The patent combines the mounting function, heat dissipation function, and electrical connection function into a single integrated holder structure. The heat dissipating plate serves as both the mounting substrate for multiple components and the thermal management system, while the terminals integrated into the holder provide electrical connections. This merging eliminates the need for separate mounting plates, heat sinks, and connection structures, thereby reducing overall module size.
3Adaptability or versatility
If a holder is added to secure additional components, then power supply capability is improved, but the overall structure becomes more complex
Solution Approach 1:
The holder is designed as a universal mounting and connection structure that simultaneously provides mechanical support, thermal management, and electrical connectivity. The multiple terminals are integrated directly into the holder body, eliminating the need for separate connection structures. This design allows the holder to accommodate various components requiring different numbers and arrangements of electrical connections without increasing structural complexity.
