Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If multiple heat generators are arranged on different container surfaces to increase light output, then luminance and light utilization efficiency are improved, but heat generation increases and cooling efficiency deteriorates
Solution Approach 1:
The patent divides the heat dissipation system into multiple independent heat dissipation members (first, second, and third heat dissipation members) corresponding to different container surfaces (first, second, and third surfaces). Each heat dissipation member is thermally connected to a specific container surface and has dedicated air intake and exhaust ports, allowing independent heat dissipation pathways for each heat generator group. This segmentation enables efficient heat removal from multiple heat generators arranged on different surfaces without thermal interference.
2Productivity
If heat generators are densely arranged to improve light utilization efficiency, then compactness is improved, but heat accumulation increases and cooling becomes less effective
Solution Approach 1:
The patent utilizes three-dimensional spatial arrangement by placing heat generators on multiple different surfaces (first surface, second surface, third surface) of the container rather than concentrating them on a single plane. This dimensional distribution, combined with heat dissipation members positioned on corresponding external surfaces with dedicated air flow paths, creates independent heat dissipation channels that prevent heat accumulation even when heat generators are densely arranged across multiple surfaces for high light utilization efficiency.
