Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
High pressure fluid processing devices require complex maintenance due to numerous parts, making quick replacement and servicing challenging, especially when compared to designs with similar functions.
Innovation Solution
A high pressure processing device with a dual check valve setup featuring independently attachable and detachable subassemblies, reducing the total number of parts and eliminating the need for gaskets, o-rings, and other deformable materials, allowing for simplified maintenance by threading subassemblies directly into recesses within the body.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a complex design with multiple parts is used to achieve high pressure fluid processing, then the device can perform its function, but maintenance becomes difficult and time-consuming
Solution Approach 1:
The device is divided into separate subassemblies (first subassembly with first check valve, second subassembly with second check valve, third subassembly with fluid driving mechanism) that can be independently attached and detached from the body through recesses, allowing individual maintenance without disrupting other components
2Reliability
If numerous parts are used in the device design, then the device can achieve high pressure fluid processing, but the total number of parts increases making maintenance challenging
Solution Approach 1:
Multiple functional components (check valves, sealing elements, mounting structures) are merged into integrated subassemblies that function as unified units, reducing the overall part count while maintaining high pressure fluid processing capability
3Reliability
If traditional sealing methods with gaskets and o-rings are used, then the device can seal properly, but maintenance requires replacement of deformable materials
Solution Approach 1:
The check valves utilize the fluid pressure itself and elastic deformation of the ball elements to automatically seal and open the flow paths, eliminating the need for separate gaskets, o-rings, or other deformable sealing materials that would require periodic replacement
