Liquid Filter Module Securing Element Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing liquid filter modules with bayonet locks for securing bypass valves are structurally complex, expensive, and increase storage and logistics costs, requiring additional assembly work and separate sealing plugs when a bypass valve is not desired.
Innovation Solution
A simpler securing element, such as a sleeve or positioning pin, is used to secure the built-in part within the liquid filter module, eliminating the need for complex fastening technologies like bayonet locks and allowing existing components to serve additional functions, thereby reducing design effort and manufacturing costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a bayonet lock is used to secure the bypass valve on the intermediate piece, then the valve is firmly fixed, but the structure becomes complex and expensive with additional components
Solution Approach 1:
The patent combines the fastening function with the intermediate piece itself by integrating a threaded bore directly into it. The closure element is screwed directly into the intermediate piece, merging the fastening mechanism with the structural component, thereby eliminating the need for separate bayonet lock assemblies while maintaining secure fixation
Solution Approach 2:
The intermediate piece is designed with multi-functionality: it serves both as a structural spacer and as a fastening element. The threaded bore in the intermediate piece allows it to perform both structural support and valve securing functions, reducing the need for additional specialized components
2Reliability
If a bayonet lock is used for fixing the valve, then the valve is securely mounted, but assembly and disassembly require additional work and time
Solution Approach 1:
By integrating the threaded fastening mechanism directly into the intermediate piece, the patent reduces the number of assembly steps. The closure element is screwed directly into the intermediate piece's threaded bore, eliminating the need for separate bayonet lock assembly steps and reducing overall assembly time while maintaining secure mounting
3Reliability
If a separate sealing plug is installed when a bypass valve is not desired, then sealing is achieved, but costs increase
Solution Approach 1:
The closure element serves multiple functions: it acts as both a sealing component and a fastening element. By integrating the sealing function into the closure element that is already screwed into the intermediate piece, the patent eliminates the need for separate sealing plugs, reducing part count and manufacturing costs while maintaining reliable sealing
Solution Approach 2:
The patent merges the sealing function with the closure element. The closure element itself provides the sealing interface when screwed into the intermediate piece, combining what would traditionally be separate sealing and fastening components into a single integrated element, thereby reducing overall manufacturing cost
4Ease of manufacture
If existing components are used for additional functions, then design effort and manufacturing costs are reduced, but the components must handle additional loads and stresses
Solution Approach 1:
The intermediate piece is designed with multi-functionality from the outset, incorporating a threaded bore to serve both structural and fastening purposes. This design consideration ensures that the intermediate piece can handle both its structural load and the additional fastening loads without requiring separate components, maintaining strength while reducing manufacturing cost
