Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing air or gas filtration systems face challenges with high labor intensity, safety concerns, and limited adsorption capacity due to the design of replaceable filter devices, which often require manual and labor-intensive replacement of saturated adsorbent, and have uneven air resistance and pressure distribution across the filter bed.
Innovation Solution
A replaceable filter device with a rectangular-shaped upright filter housing and filter elements covering 90-100% of the internal length, where the air or gas inlet and outlet are situated in the same ground plane, allowing for mechanical tilting and connection to a coupling platform, eliminating the need for large intermediate pieces and reducing labor intensity and safety risks.

Engineering Contradiction Analysis
1Quantity of substance
If manual replacement of saturated adsorbent is used in fixed filter devices, then adsorption capacity can be maintained, but labor intensity and safety risks increase significantly
Solution Approach 1:
The filter device is segmented into replaceable filter cartridges that can be independently removed and replaced. Each cartridge contains a portion of the adsorbent material, allowing partial replacement without handling the entire adsorbent bed, thus reducing labor intensity and safety risks while maintaining overall adsorption capacity.
Solution Approach 2:
The saturated adsorbent or entire filter cartridge is extracted from the filter housing as a removable component. This extraction principle allows the adsorbent to be taken out for replacement without disassembling the entire filter system, significantly reducing manual handling requirements and safety hazards associated with toxic pollutants.
2Device complexity
If traditional filter device design is used, then structural simplicity is maintained, but air pressure distribution across the filter bed becomes uneven
Solution Approach 1:
The air inlet and outlet are repositioned from traditional side-mounted configurations to the bottom ground plane of the filter housing. This dimensional change in the flow path arrangement creates a more uniform pressure distribution across the filter bed while maintaining structural simplicity, as the bottom-mounted configuration naturally distributes pressure more evenly throughout the adsorbent material.
3Ease of operation
If replaceable filter devices are used, then adsorbent replacement becomes easier, but connection and transportation costs increase due to large intermediate pieces
Solution Approach 1:
The air inlet and outlet connections are merged into the bottom ground plane of the filter housing rather than being separate intermediate components. This merging eliminates the need for large intermediate connection pieces, reducing manufacturing costs and simplifying the connection interface while maintaining the replaceability of the filter cartridges.
Solution Approach 2:
The intermediate connection pieces are extracted from the design by integrating connections directly into the ground plane. This extraction eliminates unnecessary components that会增加 manufacturing and transportation costs, while the filter cartridges themselves remain extractable for easy adsorbent replacement.
4Ease of manufacture
If filter elements cover less than 90-100% of internal length, then manufacturing is simpler, but adsorption capacity is reduced
Solution Approach 1:
The filter elements are designed to cover 90-100% of the internal length of the filter housing, implementing excessive action in terms of coverage. This near-complete or complete coverage maximizes the adsorption capacity by ensuring virtually the entire internal volume is utilized for filtration, while the manufacturing complexity remains acceptable due to the standardization of the filter cartridge design.
