Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pump designs for fluid conveyance lack ease of serviceability and efficient fluid conveyance, with complex assembly and potential for high maintenance costs due to intricate component interactions.
Innovation Solution
A pump design featuring a conveyor device with a dimensionally stable conveyor chamber element and an elastically deformable conveyor element, where the conveyor chamber element can be removed as a whole from the housing, allowing for easy exchange and maintenance, and utilizing a spring-elastic conveyor element to facilitate efficient fluid conveyance through a bulging-in effect.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the conveyor device is integrated into the housing as a single unit, then the structural integrity and sealing are improved, but the serviceability and ease of maintenance deteriorate
Solution Approach 1:
The pump is divided into two separable parts: the housing and the conveyor device. The conveyor device can be removed as a complete unit from the housing, allowing maintenance without disassembling individual components while maintaining sealing integrity when assembled.
Solution Approach 2:
The conveyor device is extracted as a removable module from the housing. This allows the conveyor device to be taken out for maintenance or replacement while leaving the housing intact, resolving the contradiction between integrated sealing and serviceability.
2Stability of the object's composition
If the conveyor chamber element is made dimensionally stable, then the structural integrity is improved, but the ease of manufacture deteriorates due to complex material requirements
Solution Approach 1:
Different parts of the pump have different dimensional stability requirements. The conveyor chamber element requires high dimensional stability, while the housing can be made of more easily manufactured materials. This local differentiation of material properties simplifies overall manufacturing.
Solution Approach 2:
The conveyor chamber element is designed with an asymmetric structure that includes an outer face for connection to the housing and an inner face for fluid conveyance. This asymmetric design allows optimized manufacturing for each surface's specific function.
3Productivity
If the conveyor element is made elastically deformable, then the fluid conveyance efficiency is improved through the bulging-in effect, but the reliability deteriorates due to potential deformation and wear
Solution Approach 1:
The elastically deformable conveyor element is combined with the dimensionally stable conveyor chamber element. The deformable element provides efficient fluid conveyance through bulging, while the stable chamber element provides a reliable structural framework that prevents excessive deformation and wear.
Solution Approach 2:
The conveyor element is made as a flexible, elastically deformable component that can bulge during operation to efficiently convey fluid. The flexibility is controlled within elastic limits to maintain reliability over time.
