Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Temperature

If multiple pumps are used to cool multiple heat sources, then heat dissipation effectiveness is improved, but device complexity and connection difficulty increase

Engineering Contradiction:
Improveheat dissipation effectivenessVSAvoidconnection complexity
Core Design Contradiction:
TemperatureVSDevice complexity

Solution Approach 1:

The patent combines multiple pump functions into a single integrated pump body with multiple pump chambers (first, second, third pump chambers). Each chamber has its own impeller driven by a common drive shaft, allowing multiple liquid flows to be generated from one unified structure. This merging approach maintains effective heat dissipation for multiple heat sources while eliminating the need for multiple separate pumps and their complex interconnections.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The single pump body performs multiple cooling functions simultaneously through its multiple pump chambers. The first pump chamber cools the first heat source, the second pump chamber cools the second heat source, and the third pump chamber provides additional cooling capacity. This multi-functional design allows one pump to replace what would traditionally require multiple separate pumps, simplifying the overall system architecture.

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

2Temperature

If multiple pumps are used for multiple heat sources, then cooling coverage is improved, but miniaturization becomes difficult

Engineering Contradiction:
Improvecooling coverageVSAvoiddevice size
Core Design Contradiction:
TemperatureVSVolume of moving object

Solution Approach 1:

The pump design features nested pump chambers where the second pump chamber is positioned within or adjacent to the first pump chamber, and the third pump chamber is integrated into the same pump body structure. The impellers are arranged concentrically or in close proximity, sharing common structural elements and the drive shaft. This nesting arrangement provides extensive cooling coverage for multiple heat sources while maintaining a compact overall pump volume that enables miniaturization.

Inventive Principle:
Principle #7Nested doll (Nesting)

3Device complexity

If a single pump is used, then device complexity is reduced, but heat dissipation effectiveness for multiple sources decreases

Engineering Contradiction:
Improvepump structure simplicityVSAvoidheat dissipation effectiveness
Core Design Contradiction:
Device complexityVSTemperature

Solution Approach 1:

The single pump body is segmented into multiple independent pump chambers (first, second, and third pump chambers), each capable of independently pumping liquid to different heat sources. Each chamber has its own impeller that can be independently controlled via the drive shaft. This segmentation allows the single pump to effectively dissipate heat from multiple sources by directing liquid flow to different locations, maintaining heat dissipation effectiveness while preserving structural simplicity.

Inventive Principle:
Principle #1Segmentation
