Compressor Filter Assembly with Reusable Holder
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional compressor system filters, particularly cartridge filters, result in significant material waste and increased costs due to the need for frequent replacement of entire filter units, rather than just the filter media.
Innovation Solution
A reusable filter element holder and replaceable filter element design, where the filter medium is easily swapped out once its service life ends, reducing material waste and lowering servicing costs by decoupling the filter media from the structural components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of substance
If conventional cartridge filters are used in compressor systems, then filtration function is provided, but entire filter units must be replaced frequently resulting in material waste and increased costs
Solution Approach 1:
The filter assembly is divided into distinct segments: a reusable holder assembly and a replaceable filter element. The holder assembly includes a housing and mounting structures that remain in the system, while only the filter element (containing the media) is replaced after service life expiration. This segmentation eliminates the need to discard the structural components, reducing material waste while maintaining ease of replacement operation.
Solution Approach 2:
The filter media is extracted from the conventional integrated cartridge filter design and positioned within a separate, reusable holder assembly. This allows the filter media to be independently replaced without removing or discarding the holder, mounting structures, or housing components. The extraction enables selective replacement of only the consumable filter element.
2Reliability
If entire filter units are replaced frequently, then filtration performance is maintained, but servicing costs increase due to disposal of functional structural components
Solution Approach 1:
By segmenting the filter assembly into reusable structural components and replaceable filter elements, the system maintains reliable filtration performance through regular element replacement while significantly reducing servicing costs. The holder assembly and mounting structures are manufactured once and reused indefinitely, eliminating the need to manufacture and dispose of entire filter units with each service interval.
Solution Approach 2:
The design enables discarding only the consumable filter element after its service life expires, while recovering and retaining the reusable holder assembly, mounting structures, and housing components for continued use. This selective discarding approach maintains filtration reliability through element replacement while recovering valuable structural components, reducing overall servicing costs.

AI summary
A compressor system includes a compressor and a filter assembly that includes a holder and a replaceable filter element positioned via the holder. The holder is formed in part of a perforated wall such as a metallic mesh material wall, forming a cavity wherein the replaceable filter element is positioned. An end cap traps the replaceable filter element within the cavity. The holder is reusable, so as to reduce material waste and cost.
