Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Power sources with multi-channel units face uneven heat distribution issues when not all channels operate simultaneously, leading to local overheating and reduced conversion efficiency.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If all channel power units operate at the same period of time, then current sharing technology can be employed to make power distribution even, but local overheating occurs when only some channel power units operate
Solution Approach 1:
The patent applies asymmetry by arranging channel power units in a staggered configuration rather than a symmetric uniform distribution. Specifically, first channel power units and second channel power units are positioned at different locations within the heat dissipation device, creating an asymmetric layout that enables more uniform heat distribution when only some channels are active, thereby preventing local overheating
2Loss of energy
If only some channel power units operate, then power loss is reduced, but uneven heat distribution causes local overheating
Solution Approach 1:
The asymmetric staggered arrangement of power units allows the system to reduce power loss by operating only necessary channels while maintaining uniform heat distribution through the strategic positioning of active and inactive units at different locations within the heat dissipation structure
Solution Approach 2:
The patent implements local quality by creating different thermal zones through the staggered arrangement, where first and second channel power units occupy different spatial regions. This allows heat from active units to be distributed across different local areas rather than concentrating in one region, preventing overheating while allowing selective operation
3Temperature
If channel power units are arranged in a staggered manner, then heat distribution becomes even, but device complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the channel power units into distinct groups (first channel power units and second channel power units) that are staggered within the heat dissipation device. This segmented approach achieves uniform heat distribution through systematic arrangement while maintaining manageable device complexity through modular organization
