Multiple-Threaded Filter Connector Adapter for Simplified Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing filter assemblies for internal combustion engines face challenges with increased manufacturing complexity and cost due to the use of nut plates and threaded connections, which require larger shell diameters and thicker walls, making adaptation difficult and expensive.
Innovation Solution
A filter assembly design featuring a multiple threaded connector adapter that allows for a standard filter cartridge to be securely coupled with a wide-interface filter head using internal and external facing threaded connectors, reducing the need for direct threaded connections and minimizing parts, thereby simplifying assembly and reducing costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If nut plates and threaded connections are used for coupling filter components, then secure mechanical connection is achieved, but manufacturing complexity and cost increase
Solution Approach 1:
The patent removes the nut plate component entirely from the filter assembly. Instead of using a nut plate with threaded connections to couple the filter head to the housing, the design integrates the threading directly into the housing bore, eliminating the intermediate nut plate part and simplifying the overall structure while maintaining secure mechanical connection.
Solution Approach 2:
The housing bore is designed to directly receive and threadedly engage the filter head stem, merging the functions of the housing, coupling mechanism, and mounting structure into a single integrated component. This eliminates the need for separate nut plates and reduces the number of parts requiring manufacturing and assembly.
2Strength
If larger shell diameters and thicker walls are used to accommodate threaded connections, then structural integrity is improved, but manufacturing cost and adaptability decrease
Solution Approach 1:
The housing bore is designed with universal threading capabilities that can accommodate different filter head stem sizes and thread configurations. This multi-functional bore design allows the same housing structure to work with various filter elements without requiring custom-molded housings for each application, thereby reducing manufacturing costs and improving adaptability.
3Ease of operation
If multiple separate components are used for filter assembly, then ease of assembly is improved, but device complexity increases
Solution Approach 1:
The filter assembly is designed as an integrated unit where the housing, bore, and coupling structures are formed as a single piece. The filter element is directly inserted and secured within this integrated housing, eliminating the need for separate nut plates, gaskets, and multiple fastening components, thereby reducing part count while maintaining ease of assembly.
