Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Use of energy by moving object

If turbulence generators are installed inside block flow paths to enhance heat transfer, then heat transfer efficiency is improved, but the turbulence generators cannot be firmly fixed and deform

Engineering Contradiction:

Improveheat transfer efficiencyVSAvoidfixing reliability

Core Design Contradiction:

Use of energy by moving objectVSReliability

Solution Approach 1:

The cap integrates multiple functions: it seals the block body, provides flow path connections, and incorporates fixing protrusions that engage with recesses in the turbulence generator. This merging of functions into a single component solves the fixing reliability problem while maintaining heat transfer efficiency.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The fixing protrusion and recess structure acts as an intermediary mechanical connection between the cap and turbulence generator. This intermediate fixing mechanism enables reliable attachment without requiring separate dedicated fixing parts, resolving the contradiction between enhancing heat transfer and ensuring proper fixation.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Length of moving object

If caps are installed at both ends of the block body to connect flow paths, then the working fluid flow path is extended, but significant flow loss occurs in the connection flow paths

Engineering Contradiction:

Improveflow path lengthVSAvoidflow loss

Core Design Contradiction:

Length of moving objectVSLoss of energy

Solution Approach 1:

The connection flow path is designed with a curved surface instead of sharp angles or abrupt transitions. This curved geometry reduces flow separation and turbulence at the cap connections, minimizing energy loss while maintaining an extended flow path length for effective heat dissipation.

Inventive Principle:

Principle #14Spheroidality (Curvature)

3Reliability

If O-rings are placed between the block body and caps to prevent leakage, then sealing is provided, but the O-rings are not fixed at correct positions and shift during coupling

Engineering Contradiction:

Improvesealing reliabilityVSAvoidseal positioning accuracy

Core Design Contradiction:

ReliabilityVSManufacturing precision

Solution Approach 1:

The cap design incorporates the sealing function directly into its structure through integrated sealing surfaces and positioning features. The cap itself provides the sealing action and positioning, eliminating the need for separate O-rings that require precise manual positioning. This self-service approach ensures both sealing reliability and positioning accuracy.

Inventive Principle:

Principle #25Self-service

AI summary

Proposed is a heat dissipating device using turbulent flow. In the heat dissipating device, a plurality of block flow paths (12) are formed in parallel inside a block body (10), a first cap (16) and a second cap (28) are mounted on side surfaces (15) of the respective ends of the block body (10) so as to connect the block flow paths (12), a working fluid flows into the block flow paths (12), and the working fluid which has passed through the block flow paths (12) is transferred to the outside. Turbulence generators (38) are mounted inside the block flow paths (12), and finishing end portions (40) on the respective ends of the turbulence generators (38) are supported by the first cap (16) and the second cap (28) and are positioned inside the block flow paths (12).
