Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If 3D VC-form heat dissipators are used for thermal relief in local high heat flow regions, then heat dissipation effectiveness is improved, but the risk of leakage increases and reliability decreases

Engineering Contradiction:

Improveheat dissipation effectivenessVSAvoidrisk of leakage

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The heat dissipation system is segmented into distinct functional components: a base plate for heat collection, a heat dissipation component with pipelines for fluid circulation, and a shell for containment. This segmentation allows each component to be optimized independently, improving overall reliability while maintaining heat dissipation effectiveness.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

A working fluid serves as an intermediary medium to transfer heat from the base plate through the heat dissipation pipelines to the shell. This intermediary approach eliminates direct thermal contact requirements and reduces leakage risks by using sealed fluid circulation paths.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Productivity

If 3D VC heat dissipation module is placed vertically, then heat dissipation performance is improved, but the top of heat collection cavity is prone to dry burning leading to over-temperature failure

Engineering Contradiction:

Improveheat dissipation performanceVSAvoidover-temperature failure risk

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The base plate is designed with a heat collection cavity that pre-positioned heat gathering structures to ensure uniform heat distribution before the working fluid enters the heat dissipation pipelines. This preliminary heat collection action prevents localized overheating and dry burning conditions.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system changes the physical state and circulation parameters of the working fluid to ensure continuous wetting of the heat collection cavity surface. By controlling fluid flow rate, pressure, and temperature parameters, the system maintains reliable heat transfer without dry burning.

Inventive Principle:

Principle #35Parameter changes

3Ease of manufacture

If heat dissipation assembly structure is simplified, then manufacturing ease is improved, but pressure-bearing capability and structural strength deteriorate

Engineering Contradiction:

Improvestructural simplicityVSAvoidpressure-bearing capability

Core Design Contradiction:

Ease of manufactureVSStrength

Solution Approach 1:

The base plate serves multiple functions simultaneously: it acts as a heat collection surface, a structural support element, and a mounting platform for the heat dissipation component. This multi-functionality reduces the number of separate parts needed while maintaining structural strength and pressure-bearing capability.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The heat dissipation component is merged with the shell structure, where the shell serves both as a containment housing and as part of the heat dissipation pathway. This merging simplifies the overall assembly while maintaining structural integrity and pressure resistance.

Inventive Principle:

Principle #5Merging (Combining)
