Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the transformer and battery cell are integrated into a same shell with close proximity to ensure portability, then the portability is improved, but the heat of the transformer is easily conducted to the battery cell, affecting the safety of the battery cell
Solution Approach 1:
The patent divides the transformer into multiple transformer modules (first transformer module, second transformer module, third transformer module) that are spatially separated from the battery cell. Each transformer module is positioned at different distances from the battery cell, creating a segmented heat dissipation structure that reduces overall heat conduction while maintaining compact form factor for portability.
Solution Approach 2:
The patent introduces a heat dissipation structure that acts as an intermediary between the transformer modules and the battery cell. This heat dissipation structure includes heat dissipation fins and is positioned between the transformer modules and battery cell to intercept and dissipate heat before it reaches the battery, thereby protecting the battery from thermal damage while allowing close integration for portability.
2Temperature
If multiple transformer modules are used to increase heat dissipation area, then the heat dissipation efficiency is improved, but the device complexity increases
Solution Approach 1:
The patent arranges the first, second, and third transformer modules in a nested or layered configuration around the battery cell, with each module positioned at different radial distances. This nested arrangement maximizes the use of available space within the compact shell, increasing the total heat dissipation surface area without significantly increasing the overall device volume or complexity.
Solution Approach 2:
The patent transitions from a single-plane transformer configuration to a three-dimensional multi-layered arrangement of transformer modules surrounding the battery cell. This spatial distribution in multiple dimensions increases the heat dissipation surface area exponentially without proportionally increasing device complexity, as the modules utilize vertical and radial space efficiently within the compact portable form factor.

Implementation Method 1
the two power modules have a larger surface area than a single power module under the same power, which can effectively increase the heat dissipation area, improve heat dissipation efficiency, and thus minimize the temperature of the cell module
