Filter Frame Clamping Structure for Glue-Free Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The conventional method of gluing filter material to a frame is difficult due to small gaps, leading to potential breakage, deformation, and glue overflow, especially when using softer materials.
Innovation Solution
A filter frame with a clamping structure featuring clamping members and covering plates to securely fix the filter material, eliminating the need for gluing and minimizing glue overflow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the filter material is placed in the frame with a small gap for gluing, then the structural integrity is improved, but the gluing process becomes difficult and leads to breakage, deformation, and glue overflow
Solution Approach 1:
A clamping member is introduced as an intermediary component between the filter material and the frame. The clamping member includes a clamping plate that contacts the filter material and a clamping arm that applies clamping force, serving as a mediator to secure the filter material without requiring direct gluing, thus avoiding the problems of glue overflow and difficult gluing process while maintaining structural integrity
Solution Approach 2:
The chemical bonding method (gluing) is replaced with a mechanical clamping system. The clamping member uses mechanical force through the clamping arm to hold the filter material in place, substituting the chemical adhesive process with a purely mechanical fastening mechanism that eliminates gluing difficulties
2Manufacturing precision
If the gluing nozzle is inserted into the gap between the filter material and the frame for smooth gluing, then the gluing quality is improved, but the filter material and frame are subjected to extrusion causing breakage and deformation
Solution Approach 1:
The clamping member acts as an intermediary that separates the filter material from direct contact with the frame during assembly. This intermediary structure allows the filter material to be secured without requiring nozzle insertion into tight gaps, eliminating the extrusion forces that cause breakage and deformation while still achieving secure attachment
Solution Approach 2:
The clamping member is installed beforehand to secure the filter material in position before any gluing operation. This preliminary clamping action maintains the filter material's position and prevents deformation during subsequent assembly steps, eliminating the need to insert nozzles into tight gaps
3Strength
If the filter material is secured using conventional gluing methods, then the attachment is achieved, but the process is time-consuming and prone to defects
Solution Approach 1:
The chemical adhesive process is replaced with a mechanical clamping system that can be quickly installed and adjusted. The clamping member provides immediate mechanical attachment without requiring glue application, drying time, or complex positioning, significantly improving assembly speed while maintaining secure attachment
Solution Approach 2:
The clamping member incorporates adjustable and removable features that allow dynamic assembly and disassembly. The clamping force can be adjusted during installation, and the entire clamping member can be quickly removed for filter replacement, enabling rapid assembly cycles compared to permanent gluing methods

AI summary
A filter frame with a clamping structure includes a frame (10) and multiple side walls (15) formed on the inner looped side. Each side wall (15) is adjacent to the front side (13) and the rear side (14) respectively. There are two clamping members (20) respectively placed on the inner looped sides of the left side and the right side of the frame (10). The clamping members (20) are configured to clamp the filter material (50) within the frame (10). Therefore, when the filter material (50) is placed in the frame (10), the clamping members (20) on both sides can extend into the space between the two closest pieces of the filter material (50) on both sides, allowing the closest piece of the filter material (50) to be clamped and tightly attached to the short frame bars (12).
