Pleated Filter Holder Assembly to Prevent Tearing Damage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing filter medium holders risk damaging pleated filters during assembly due to excessive tension, particularly when folding higher numbers of pleats.
Innovation Solution
A holder with a support device and a fixing device, where the fixing elements are movable and introduced sequentially into gaps between support elements, allowing for reliable folding and retention of the filter medium without excessive tension, and featuring a locking mechanism to secure the pleated structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If one part is pushed into the other to assemble the filter holder, then the filter medium is held in folded form, but the filter medium risks tearing due to excessive tension
Solution Approach 1:
The holder is divided into two separate parts: a support device with support elements and a fixing device with fixing elements. These parts are assembled separately and then connected, allowing the filter medium to be folded and secured without the damage risk of pushing one part into another. The segmentation enables controlled folding and fixing processes.
Solution Approach 2:
The filter medium is pre-folded into the desired pleated configuration before being placed into the holder. The support elements and fixing elements are positioned in advance to receive and secure the pre-folded filter medium, preventing excessive tension and tearing during the folding process itself.
2Productivity
If multiple fixing elements are introduced simultaneously, then the filter medium is secured quickly, but excessive tension causes damage to the filter medium
Solution Approach 1:
The fixing elements are introduced in a sequential, periodic manner rather than simultaneously. Each fixing element is inserted one after another, allowing the filter medium to be gradually secured without experiencing excessive tension from multiple simultaneous fixing actions. This periodic introduction maintains both assembly efficiency and filter medium integrity.
