Removable Valve Group for Vehicle Cooling Pump Adaptability
Find Innovative SolutionsGenerate Solutions
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
Engineering 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
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.
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
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.
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.
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
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.
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
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.
