Solution Overview

Problem

Existing cooling pump designs for vehicles lack an efficient and easily modifiable valve group that can effectively manage liquid flow based on temperature conditions, leading to suboptimal performance and production inefficiencies.

Innovation Solution

A mechanically driven cooling pump with a valve group comprising a cartridge-style valve body, an obturator, and drive means, including a shaft, disc, pin, and rod, which can be actuated to control liquid flow through a delivery chamber and pipe, with integrated heat detection for adaptive operation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a traditional integrated valve group design is used, then the pump structure is simpler, but the valve cannot be easily modified or optimized separately from the pump body

Engineering Contradiction:
Improvevalve modifiabilityVSAvoidpump structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The valve group is separated from the pump body into an independent, removable module. The valve body can be extracted from the pump housing through a housing compartment, allowing the valve to be designed, manufactured, and optimized independently while maintaining a relatively simple overall pump structure.

Inventive Principle:
Principle #1Segmentation

2Ease of manufacture

If the valve group is made as a separate removable module, then the valve can be optimized independently and produced separately, but the assembly and sealing requirements become more complex

Engineering Contradiction:
Improvevalve productionVSAvoidassembly sealing
Core Design Contradiction:
Ease of manufactureVSManufacturing precision

Solution Approach 1:

The valve group is designed as a separate module that can be manufactured independently and then assembled into the pump. This segmentation allows for specialized valve production facilities and processes while maintaining manageable assembly requirements through standardized interfaces.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

A sealing element acts as an intermediary between the valve body and pump housing, facilitating the connection while ensuring proper sealing. This intermediary component handles the sealing requirements, allowing the valve and pump to be manufactured separately with controlled precision requirements.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Ease of repair

If the valve group is integrated into the pump body, then assembly is simpler, but the valve cannot be easily replaced or upgraded

Engineering Contradiction:
Improvevalve replacementVSAvoidvalve group structure
Core Design Contradiction:
Ease of repairVSDevice complexity

Solution Approach 1:

The valve group is segmented from the pump body as a removable module, enabling easy replacement and upgrading of the valve without affecting the pump body. The valve can be extracted through the housing compartment, facilitating maintenance and upgrades while keeping the overall structure relatively simple.

Inventive Principle:
Principle #1Segmentation

4Adaptability or versatility

If a fixed valve design is used, then the pump structure is more stable, but the pump cannot adapt to different temperature conditions and flow requirements

Engineering Contradiction:
Improvetemperature adaptationVSAvoidvalve control mechanism
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The valve is designed with movable components including a disc and pin mechanism that can change the valve opening degree dynamically. The pin can be positioned at different locations on the disc, allowing the valve to adapt to different temperature conditions and flow requirements while maintaining a relatively simple control mechanism.

Inventive Principle:
Principle #15Dynamics
