Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If each solid state light emitting device is provided with a separate heat sink, then heat dissipation effectiveness is improved, but device size increases due to required installation area for multiple heat sinks
Solution Approach 1:
The patent merges multiple separate heat sinks into a single integrated heat releaser that cools multiple solid state light emitting devices simultaneously. The heat releaser includes a single heat dissipation structure with multiple cooling channels that receive heat from different light emitting devices, eliminating the need for separate heat sinks for each device while maintaining effective heat dissipation.
Solution Approach 2:
The heat releaser is designed as a universal cooling component that serves multiple functions by cooling several different solid state light emitting devices through a single structure. It includes multiple heat receiving portions that can interface with different light emitting devices, making it a multi-functional heat dissipation solution that reduces overall device size.
2Reliability
If multiple separate heat sinks are used for each light emitting device, then heat management reliability is improved, but device complexity increases due to multiple independent cooling components
Solution Approach 1:
The patent combines multiple independent cooling components into a single integrated heat releaser assembly. This unified structure includes multiple heat receiving portions and cooling channels that work together as one system, reducing the number of discrete components while maintaining reliable heat management through integrated thermal pathways.
Solution Approach 2:
The heat releaser is segmented into multiple functional regions including separate heat receiving portions for different light emitting devices and multiple cooling channels within a single structure. This segmentation allows independent heat management for each light emitting device while using a unified cooling system, balancing reliability with reduced complexity.
