Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If a single fluid flow path is used in the cooling system, then the device complexity is reduced, but the heat dissipation efficiency is limited

Engineering Contradiction:

Solution Approach 1:

The cooling system is divided into multiple independent fluid flow paths (first fluid flow path, second fluid flow path, etc.), each capable of carrying cooling fluid separately. This segmentation allows parallel heat removal from different heat transfer elements, increasing overall heat dissipation efficiency while maintaining manageable system complexity through modular path design.

Principle #1Segmentation

2Productivity

If multiple heat transfer elements are used to increase heat dissipation, then the heat removal capability is improved, but the thermal contact area with the heat-generating component is limited

Engineering Contradiction:

Solution Approach 1:

The patent transitions from a single-plane heat transfer approach to a multi-dimensional heat removal system. Multiple heat transfer elements are arranged in different spatial configurations (e.g., stacked or distributed across multiple surfaces), allowing heat to be removed from various zones of the heat-generating component simultaneously. This dimensional expansion effectively increases the total thermal contact area without concentrating all heat transfer in one location.

Solution Approach 1:

The cooling system is divided into multiple independent but identical modules, each consisting of a heat transfer element connected to a fluid flow path. This modular segmentation allows for standardized manufacturing of individual units that can be assembled in series to achieve the required heat dissipation capacity. Each module can be manufactured and tested independently, simplifying the overall manufacturing process while scaling the heat dissipation capacity by adding more modules.
