Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If heat dissipation fins are arranged on the housing outer surface, then heat dissipation capability is improved, but the overall weight of the converter increases
Solution Approach 1:
The patent applies local quality by creating different heat dissipation regions with varying fin lengths. The first heat dissipation region has longer fins for areas requiring greater heat dissipation, while the second region has shorter fins. This localized differentiation optimizes heat dissipation effectiveness in specific areas without uniformly increasing weight across the entire converter structure.
Solution Approach 2:
The heat dissipation fins are segmented into multiple regions with different characteristics. The housing outer surface is divided into a first heat dissipation region and a second heat dissipation region, each with fins of different lengths. This segmentation allows the system to address varying heat generation levels at different locations, improving overall heat dissipation efficiency while controlling total weight.
2Temperature
If heat dissipation fins are arranged to cover the housing outer surface, then heat dissipation efficiency is improved, but the device complexity increases
Solution Approach 1:
The patent implements local quality by differentiating the heat dissipation fin structure into two distinct regions. The first region features longer fins extending from the housing, while the second region has shorter fins. This localized variation targets heat dissipation resources to areas of highest thermal demand, improving efficiency without requiring a uniformly complex structure across the entire device.
Solution Approach 2:
The heat dissipation structure is segmented into multiple functional regions based on thermal requirements. By dividing the housing outer surface into a first heat dissipation region and a second heat dissipation region with different fin configurations, the patent simplifies the overall design compared to a uniform high-performance structure, while still achieving effective heat dissipation where needed.
