Filter Frame Glue-Cutting Segment for Efficient Cartridge Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional filter cartridge assembly methods are inefficient due to the need for a glue gun to be inserted into a wide gap between the filter core and frame, which reduces assembly efficiency, narrows the filter core diameter, and increases glue usage.
Innovation Solution
A filter frame with a glue-cutting segment that allows for the pre-coating of glue on the filter core, which is then cut and sealed by the frame's annular slope, eliminating the need for a wide gap and reducing glue consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a wide gap is provided between the filter core and filter frame to accommodate the glue gun head, then the glue can be properly applied to seal the gap, but the filtering area of the filter core is reduced and the assembly efficiency is lowered
Solution Approach 1:
The patent applies preliminary action by pre-coating the glue on the filter core before mounting it in the filter frame. This eliminates the need to insert the glue gun into the narrow gap between the filter core and frame, as the glue is already applied in advance when access is easier. The pre-applied glue is then compressed to fill the gap and seal the joint effectively.
2Ease of manufacture
If a wide gap is provided between the filter core and filter frame for glue gun access, then the glue can be applied, but more glue is required which increases waste
Solution Approach 1:
By pre-coating the glue on the filter core before assembly, the process controls the amount of glue applied more precisely. The glue is applied only where needed on the filter core surface, and during compression, the excess glue is squeezed out and can be removed or reused, minimizing waste compared to filling a wide gap.
Solution Approach 2:
The patent changes the parameter of gap width between the filter core and filter frame from wide to narrow. This parameter change reduces the volume of glue required to fill the gap, thereby reducing glue consumption and waste while still achieving effective sealing through the compression process.
3Ease of operation
If the filter core diameter is reduced to accommodate a wide gap, then the glue gun can access the gap, but the filtering area is decreased
Solution Approach 1:
The patent performs the glue application action in advance before the filter core is mounted in the frame. This preliminary action allows the filter core to maintain its full design diameter without needing to accommodate a wide gap for glue gun access during assembly. The glue is applied when the core is accessible, then the core is mounted with minimal gap.
4Ease of manufacture
If the gap between filter core and frame is widened for glue application, then the glue gun can be inserted, but the assembly time and effort increase
Solution Approach 1:
The patent applies glue as a preliminary step before mounting the filter core in the frame, rather than attempting to apply glue within the narrow gap during final assembly. This resequencing of operations eliminates the time-consuming step of inserting and maneuvering the glue gun in the gap, significantly reducing assembly time and effort.

AI summary
A filter frame, a filter cartridge, and an assembling method of the filter cartridge are provided. The method has the following steps. A filter core and a filter frame are prepared. The filter frame has a glue-cutting segment. Glue is coated around an outer wall of the filter core, and then the filter frame, which is mounted around the filter core, is pushed toward the glue to make the glue-cutting segment press the glue until the glue is cut into two parts. The inner glue part disposed between the filter core and the filter frame seals the filter cartridge. The outer glue part is disposed on an outer side of the filter frame, and is superfluous and removed. The glue-coating is combined with the mounting of the filter frame, thereby saving time and effort.
