Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional air flow cooling methods are used, then the cooling system is simple, but the cooling effectiveness is insufficient in extreme temperature environments

Engineering Contradiction:
Improvecooling effectivenessVSAvoidcooling system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines the support structure for electronic components with the cooling fluid conduit system into an integrated assembly. The conduit is formed as part of the support structure itself, eliminating the need for separate external conduits and reducing overall system complexity while maintaining effective cooling performance in extreme environments.

Inventive Principle:
Principle #5Merging (Combining)

2Device complexity

If external conduits are used to supply cooling fluid, then the fluid delivery system is simple to manufacture, but the overall assembly becomes more complex and heavier

Engineering Contradiction:
Improveassembly complexityVSAvoidassembly weight
Core Design Contradiction:
Device complexityVSWeight of stationary object

Solution Approach 1:

The support structure and cooling conduit are merged into a single integrated component. The conduit is formed directly as part of the support structure, eliminating separate external conduits and reducing the number of parts, assembly steps, and overall weight of the assembly.

Inventive Principle:
Principle #5Merging (Combining)

3Weight of stationary object

If a compact integrated structure is used, then the assembly is more weight-efficient and compact, but the assembly process becomes more complex

Engineering Contradiction:
Improveassembly weightVSAvoidassembly ease
Core Design Contradiction:
Weight of stationary objectVSEase of manufacture

Solution Approach 1:

The conduit is pre-formed as an integral part of the support structure during manufacturing, before final assembly. This preliminary integration of the conduit into the support structure simplifies the final assembly process, as the conduit is already in position and does not require separate installation steps.

Inventive Principle:
Principle #10Preliminary action

4Device complexity

If tubes are inserted into the support structure, then exposed fluid conduits are minimized, but the insertion process requires precise positioning

Engineering Contradiction:
Improveconduit exposureVSAvoidtube positioning precision
Core Design Contradiction:
Device complexityVSManufacturing precision

Solution Approach 1:

The tube is merged with the support structure to form an integrated conduit system. The tube is pre-positioned and integrated during manufacturing, eliminating the need for precise field positioning and reducing exposed conduits. The integration ensures proper positioning without requiring complex alignment procedures during assembly.

Inventive Principle:
Principle #5Merging (Combining)
