Pocket Filter Assembly Nested Subframe Interlock
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pocket filter assemblies face challenges in ease of production, assembly, and sealing efficiency, particularly in preventing air or gas leakage, and require complex interlocking mechanisms that complicate logistics.
Innovation Solution
The design integrates the inner subframe within the outer subframe, using locking elements with projections and receiving apertures to secure the subframes at distributed positions, which also involves filter pocket material for enhanced sealing and holding, allowing for non-detachable interlocking and the use of peripheral surfaces for sealing rather than interconnection, enabling easier assembly and improved sealing properties.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If detachable interconnection mechanisms are used between subframes, then ease of assembly and disassembly is improved, but device complexity and logistics complexity increase
Solution Approach 1:
The inner subframe is nested within the outer subframe, with inner subframe portions received in hollow outer subframe portions. This nesting arrangement creates a compact structure that simplifies the overall assembly while maintaining ease of assembly through the integrated design of the nested components.
2Reliability
If complex interlocking mechanisms are used to secure subframes, then reliability of connection is improved, but device complexity and manufacturing difficulty increase
Solution Approach 1:
The locking elements are integrated into the subframe structures themselves, with locking projections formed on the inner subframe and receiving apertures formed in the outer subframe. This merging of the locking function into the structural components eliminates the need for separate complex interlocking mechanisms while maintaining secure connection reliability.
3Strength
If peripheral surfaces of subframes are used for interconnection, then structural strength is improved, but sealing capability is worsened
Solution Approach 1:
The subframe structure is segmented into distinct functional zones: peripheral surfaces dedicated to sealing with flat unpenetrated outer side surfaces, and internal locking elements for structural interconnection. This segmentation allows the peripheral surfaces to maintain their sealing capability while the internal locking elements provide the structural strength for interconnection.
4Reliability
If multiple locking positions are distributed along opening portions, then sealing efficiency is improved, but manufacturing complexity increases
Solution Approach 1:
The locking elements (projections and receiving apertures) are integrated directly into the molded subframe structures, combining the locking function with the structural components. This integration simplifies manufacturing as the locking features are formed as part of the subframe production process rather than requiring separate manufacturing steps for multiple locking positions.

AI summary
A pocket filter assembly includes a frame structure having a plurality of filter pocket openings and a corresponding plurality of filter pockets, each filter pocket having a pocket mouth securely sealed in a corresponding filter pocket opening. The frame structure includes an outer subframe and a corresponding inner subframe connected and locked to each other by means of locking elements at locking positions distributed along opening portions of the subframes defining the filter pocket openings. At each locking position, the filter pocket mouths are sealed clamped and sealed between co-operating opening portions of the subframes. The locking elements include an undercut hook-shaped projection on the inner subframe and a co-operating receiving hole on the outer subframe, such that an interlock of the subframes to each other is obtained, while including filter pocket mouth material of the associated filter pocket between said projection and said aperture such that said interlock is sealed thereby.
