Filter Device Bypass Valve Segmentation for Metal-Free Disposal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing filter devices face challenges in achieving a simple and compact design while ensuring operational reliability and low manufacturing costs, particularly in the design of the bypass valve, which requires decoupling from the closing spring for cost-effective and safe replacement of filter elements.
Innovation Solution
The filter element incorporates a bypass valve integrated with an end cap, where the closing body can be moved against the force of a compression spring, allowing for a fluid-tight closure and opening, and is designed to be removable from the casing, with a shaft and projection mechanism ensuring functional reliability and easy separation from the closing spring, allowing for metal-free incineration of the filter element.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the bypass valve is integrated with the filter element including the closing spring, then the design is simpler and more compact, but the filter element cannot be disposed of metal-free and replacement costs increase
Solution Approach 1:
The bypass valve is segmented into two separable parts: the closing body (with valve seat and shaft) integrated with the filter element, and the closing spring remaining in the housing. This segmentation allows the filter element to be removed and disposed of metal-free while the spring remains behind, resolving both the complexity and disposal cost issues.
Solution Approach 2:
The closing spring is extracted from the filter element and left in the housing, separating it from the disposable filter component. This extraction enables the filter element to be metal-free and environmentally friendly while maintaining the bypass valve's functional integrity through the remaining closing body components.
2Reliability
If the closing body is made of metal for durability, then operational reliability improves, but the filter element cannot be incinerated and disposal costs increase
Solution Approach 1:
Different materials are used for different parts of the bypass valve: the closing body and shaft are made of metal for durability and reliability, while the filter element housing is metal-free for incineration. This local quality differentiation allows the critical functional parts to be metal while enabling environmentally friendly disposal of the non-critical housing.
Solution Approach 2:
The bypass valve components have asymmetric material composition where only the essential closing body and shaft are metal, while the filter element housing is metal-free. This asymmetric design ensures operational reliability where needed while enabling eco-friendly disposal where not critical.
3Ease of manufacture
If the bypass valve closing body is integrated with the filter element, then manufacturing cost decreases, but the valve may fail when the filter element is removed
Solution Approach 1:
The closing body, valve seat, and shaft are merged into a single integrated component that remains with the filter element during removal. This merging ensures the bypass valve remains functional and complete when the filter element is extracted from the housing, maintaining reliability while reducing manufacturing costs.
Solution Approach 2:
The closing body serves multiple functions: it acts as both the valve closure component and the mounting structure for the shaft and valve seat. This multi-functionality reduces the number of separate parts needed, lowering manufacturing costs while ensuring the bypass valve remains operational when the filter element is removed.

AI summary
The invention relates to a filter device. The invention further relates to a filter device comprising a filter element (1), which can be removably accommodated in a sheathing (13) and the filter material (9) of which, through which the fluid to be cleaned can flow, separates a space (3) forming the dirty side during the filtration process from a space forming the clean side, and comprising a bypass valve, the closing body (41) of which, when the pressure difference in the spaces exceeds a limit value range, can be moved counter to the action of a closing spring (21) into an open position that allows the pressure difference to be reduced, is characterized in that the closing body (41) as part of the filter element (1) can be removed from the sheathing (13) while attached to the filter element and can be spatially separated from the closing spring (21) in doing so.
