Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If separate elements are used for cooling and power supply, then the functions are clearly separated, but the device complexity and heat generation increase

Engineering Contradiction:
Improvefunctional separationVSAvoiddevice complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines the power supply function and cooling function into a single integrated element. The first layer serves dual purposes: it conducts electricity to supply power to electronic components while simultaneously conducting heat away from them. This merging eliminates the need for separate power supply traces and cooling structures, thereby reducing device complexity while maintaining functional reliability.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The first layer of the cooling module is designed to perform multiple functions simultaneously. It acts as both an electrical conductor for power distribution and a thermal conductor for heat dissipation. This multi-functionality allows a single element to replace what would traditionally require separate components, reducing overall system complexity.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Ease of manufacture

If separate elements are used for cooling and power supply, then each function can be optimized independently, but the number of components and heat generation increase

3Power

If more power is supplied to increase computational power, then processing capability improves, but heat generation increases

Engineering Contradiction:
Improvecomputational powerVSAvoidheat generation
Core Design Contradiction:
PowerVSTemperature

Solution Approach 1:

The patent converts the harmful heat generated by high-power electronic components into a manageable thermal flow. The first layer is positioned to receive heat directly from the components and conduct it to the second layer, which dissipates the heat. This approach transforms the unwanted byproduct of high computational power into a controlled thermal management process, enabling sustained high performance without excessive temperature rise.

Inventive Principle:
Principle #22Blessing in disguise (Convert harm into benefit)

Solution Approach 2:

The cooling module with its two-layer structure acts as an intermediary between the heat-generating electronic components and the external environment. The first layer collects heat at the source, the intermediate structure (with thermal insulation) prevents heat spread to unwanted areas, and the second layer dissipates heat to the surroundings. This intermediary system enables high power operation by mediating the heat transfer process.

Inventive Principle:
Principle #24Intermediary (Mediator)
