Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If brazing coupling is used to form the heat exchanger, then heat exchange efficiency is improved, but the electrical device cannot be inserted after the insertion space is fixed

Engineering Contradiction:
Improveheat exchange efficiencyVSAvoidassembly ease
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The heat exchanger is divided into multiple modular units, each comprising a tube-type cooling path part and connection plates. These modular units can be independently assembled and then coupled together through connection blocks, allowing the electrical device to be inserted before final assembly. This segmentation resolves the contradiction by enabling both efficient brazing coupling within modules and easy insertion during assembly.

Inventive Principle:
Principle #1Segmentation

2Ease of operation

If the interval between tubes is widened to facilitate insertion of the electrical device, then assembly ease is improved, but the electrical device and tube are not tightly pressed against each other

Engineering Contradiction:
Improveinsertion easeVSAvoidheat exchange efficiency
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The connection plates and connection blocks are designed to apply pressing force that dynamically adjusts the interval between tubes. During assembly, the electrical device can be inserted with sufficient clearance, but after assembly, the connection components exert force to tighten the contact between the electrical device and tubes. This dynamic adjustment resolves the contradiction by providing both easy insertion and tight pressing contact.

Inventive Principle:
Principle #15Dynamics

3Force

If additional plates are provided to press the device, then pressing force is improved, but the device complexity increases

Engineering Contradiction:
Improvepressing forceVSAvoidstructure complexity
Core Design Contradiction:
ForceVSDevice complexity

Solution Approach 1:

The pressing function is merged into the connection blocks that already serve to couple the modular units together. The connection blocks simultaneously provide mechanical connection between modules and apply the necessary pressing force to ensure tight contact between the electrical device and tubes. This merging eliminates the need for additional separate pressing plates, resolving the contradiction by providing pressing force without increasing structural complexity.

Inventive Principle:
Principle #5Merging (Combining)

4Adaptability or versatility

If tanks are arranged in a zigzag pattern for multi-stage stacking, then adaptability is improved, but the connection part for inner tanks cannot be formed

Engineering Contradiction:
Improvestacking flexibilityVSAvoidconnection formation
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The connection blocks are designed with asymmetric features including protrusions and recesses that enable straightforward coupling in the stacking direction. This asymmetric design provides adaptability for multi-stage stacking while maintaining simple connection formation, as the protrusion-recess interface guides and secures the connection without requiring complex zigzag arrangements. The asymmetric connection blocks resolve the contradiction by enabling both stacking flexibility and easy connection formation.

Inventive Principle:
Principle #4Asymmetry
