Innovation Solution

A heat transfer liquid distribution device with a conduit, seal, and fixing means that allows for a sealed junction with the cooling plate using a compressible seal and reversible fixing mechanism, enabling easy assembly and separation without damage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If welding is used to join the distribution duct with the cooling plate, then sealing effectiveness is improved, but ease of repair deteriorates

Engineering Contradiction:
Improvesealing effectivenessVSAvoidease of separation
Core Design Contradiction:
ReliabilityVSEase of repair

Solution Approach 1:

The connection system is divided into separate components: a distribution duct with an external thread, a cooling plate with an internal thread, and a separate sealing element (O-ring or gasket). This segmentation allows each component to be independently replaced without affecting the others, resolving the contradiction by enabling easy repair while maintaining sealing effectiveness through the dedicated sealing element.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

A threading mechanism acts as an intermediary between the distribution duct and cooling plate, providing both mechanical connection and sealing capability. The threaded connection allows for reversible assembly and disassembly, while the accompanying sealing element ensures leak-free operation. This intermediary solution replaces the permanent weld with a controlled mechanical fastening system.
