Reusable Spin-On Filter Housing with Coreless Element
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional spin-on filter assemblies generate significant waste and volume due to their metal housing, making disposal difficult and environmentally unfriendly, and there is a need for a cost-effective and efficient design with a reusable housing and replaceable eco-friendly coreless elements.
Innovation Solution
A spin-on filter assembly with a reusable housing and a replaceable coreless element, featuring a filter bowl and a reusable adaptor with threads and radially spaced openings for fluid communication, allowing for easy decoupling and replacement of the filter element, which can be crushed or shredded for reduced waste.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a traditional metal canister housing is used in spin-on filter assemblies, then the housing provides structural strength and durability, but it generates significant waste and volume that makes disposal difficult and environmentally unfriendly
Solution Approach 1:
The filter assembly is divided into two segments: a reusable metal canister housing and a disposable paper filter element. The housing is separated from the filter element, allowing the housing to be retained and reused while only the consumable filter element is disposed of. This segmentation resolves the contradiction by maintaining the structural strength of the metal housing while eliminating the waste problem of disposing of entire metal canisters.
Solution Approach 2:
The design enables discarding only the disposable paper filter element while recovering and reusing the metal canister housing. The housing is specifically designed to be reusable across multiple filter elements, thereby recovering valuable metal resources and reducing waste generation. This principle directly addresses the contradiction by separating what should be discarded (filter element) from what should be recovered (housing).
2Strength
If a disposable metal-cored filter element is used, then the element provides structural support, but the metal core increases disposal costs and volume by preventing incineration
Solution Approach 1:
The filter element material is changed from metal-core construction to paper-based construction. This parameter change in material composition allows the filter element to be incinerated for disposal, dramatically reducing disposal volume. The paper material maintains sufficient structural strength for filter functionality while enabling environmentally friendly disposal through combustion, resolving the contradiction between strength and disposal volume.
3Object-generated harmful factors
If a reusable housing with replaceable elements is implemented, then waste is reduced and environmental friendliness is improved, but the device complexity increases due to the need for adaptors and coupling mechanisms
Solution Approach 1:
The metal canister housing is designed with universal adaptability to accommodate different disposable filter elements through standardized coupling mechanisms. The housing can accept various filter element types (different sizes, shapes, or media) while maintaining the same basic structure and coupling interface. This universality reduces environmental impact by enabling reuse of the housing across multiple applications while managing complexity through standardization rather than custom designs for each filter type.

AI summary
A spin-on filter assembly with replaceable coreless element includes a reusable spin-on housing including a filter bowl; a reusable adaptor removeably coupled to the reusable spin-on housing, including a coupling, such as a threaded coupling for removably coupling the reusable adaptor to a filter head; and a replaceable disposable nonmetal coreless filter element removably mounted on the reusable adaptor.
