Filter Element With Integrated Outlet Pipe for Lower-Cost Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing filter devices with replaceable elements are complex and costly to manufacture due to the need for separate components like a filter head and outlet pipe, which are not replaced with the element.
Innovation Solution
Integrating the outlet pipe into the filter element, eliminating the need for a separate filter head, and using a simplified structure with annular guides and support tubes made of lightweight materials to facilitate assembly and reduce manufacturing costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separate filter head and outlet pipe are used in the filter device, then the structural integrity and functionality are maintained, but the device complexity and manufacturing cost increase
Solution Approach 1:
The outlet pipe is integrated directly into the filter element, eliminating the need for a separate filter head and outlet pipe assembly. The filter element now serves dual functions: filtration and fluid conduit, reducing the number of components while maintaining functionality
Solution Approach 2:
The filter element is designed to perform multiple functions simultaneously: it acts as both the filtration medium and the outlet pipe for fluid discharge. This multi-functional design simplifies the overall device structure while maintaining all necessary functions
2Reliability
If a separate filter head and outlet pipe are used in the filter device, then the functional requirements are met, but the manufacturing cost increases
Solution Approach 1:
By combining the outlet pipe function into the filter element itself, the number of parts to be manufactured, assembled, and inventoried is reduced, directly lowering manufacturing costs while maintaining all functional requirements
Solution Approach 2:
The outlet pipe function is extracted from the separate filter head assembly and integrated into the filter element, eliminating the need for complex multi-component manufacturing processes and reducing overall production complexity
3Manufacturing precision
If tight manufacturing tolerances are applied to the outlet pipe and filter head, then the assembly precision is improved, but the manufacturing complexity and cost increase
Solution Approach 1:
Integrating the outlet pipe into the filter element eliminates the need for precision alignment and assembly between separate components, thereby reducing manufacturing tolerances requirements while maintaining assembly precision
