VSEngineering Contradiction Analysis

1Reliability

If conventional heat dissipating modules are used with simple fin structures, then the device complexity is low, but the heat dissipation efficiency is insufficient due to limited contact area with working fluid

Engineering Contradiction:
Improveheat dissipation efficiencyVSAvoidstructure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The heat dissipating module is divided into multiple heat dissipating fins, each containing multiple groove assemblies with groove units. This segmentation creates numerous interconnected channels that increase the contact area between the working fluid and the heat dissipating surface, thereby improving heat dissipation efficiency while maintaining a modular structure

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The invention introduces groove structures that extend into the thickness direction of the heat dissipating fins, creating three-dimensional interconnected channels. This dimensional transformation from simple planar fins to fins with depth-wise grooves significantly increases the surface area contact with working fluid without substantially increasing the overall footprint of the heat dissipating module

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

Solution Approach 1:

By dividing the heat dissipating fins into multiple groove assemblies with multiple groove units, the complex three-dimensional channel structure is created through systematic repetition of standardized groove patterns. This segmented approach allows for more straightforward manufacturing compared to creating entirely custom complex geometries, as the groove assemblies can be formed using standardized machining or molding processes

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The groove units are nested within groove assemblies, which are in turn arranged within the heat dissipating fins. This nested structure allows the complex interconnected channels to be formed through hierarchical organization of simpler geometric elements, facilitating manufacturing through staged processing or modular assembly

Inventive Principle:
Principle #7Nested doll (Nesting)
