Solution Overview
Problem
Existing fluid cleaning systems face challenges in reducing the effort required for arranging sealing elements and improving the function and reliability of these elements, particularly in fluid cleaning elements used for filtering and water separation.
Innovation Solution
The design incorporates an end body holding contour with a projection that tapers radially outward and a V-shaped recess in the sealing element, allowing for improved force transmission and precise fit, reducing material expenditure and enhancing the sealing element's functionality and reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a conventional sealing element design is used without a V-shaped recess, then the sealing element has sufficient material for basic sealing, but the material expenditure is high and the fit precision with the end body is insufficient
Solution Approach 1:
The sealing element features a V-shaped recess localized at the sealing surface that engages with a projection on the end body. This local geometric feature concentrates the sealing function at the critical interface, improving fit precision without requiring excess material throughout the entire sealing element structure.
Solution Approach 2:
Instead of providing a complete circumferential sealing groove that requires substantial material, the design inverts the approach by creating a V-shaped recess that receives a projection from the end body. This inversion allows the sealing element to achieve precise fit through the interlocking geometry rather than relying on material volume.
2Reliability
If the sealing element is designed with complex contours for improved sealing, then the sealing performance improves, but the effort for arranging and installing the sealing element increases
Solution Approach 1:
The V-shaped recess and projection are pre-formed during manufacturing, establishing the sealing geometry in advance. This preliminary action ensures that when the sealing element is installed, the precise fit is already built-in, reducing the effort required for arrangement and installation while maintaining high sealing performance.
Solution Approach 2:
The V-shaped recess introduces asymmetric geometry to the otherwise radially symmetric sealing element. This asymmetric feature creates a directional engagement with the projection on the end body, improving sealing reliability through precise geometric interlocking while the overall simple form factor keeps installation effort low.
