Filter Pack Frame Using Homogeneous Material
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing filter frames made from materials like metal, plastic, and wood are expensive, require additional inventory management, and pose disposal challenges due to non-flammability and water resistance issues, while bag filters suffer from structural instability and contamination re-entry.
Innovation Solution
A filter pack frame made from filter material impregnated with adhesive, allowing for in-house production and disposal as a 100% synthetic, burnable, and water-resistant solution, using materials like plastic film or wood veneer, and incorporating adhesive for structural rigidity and sealing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If traditional frame materials (metal, plastic, wood, cardboard) are used, then structural support is provided, but production cost increases and inventory management complexity increases
Solution Approach 1:
The patent combines the frame material with the filter media by directly forming the frame from the filter material itself through folding and adhesiving, eliminating the need for separate frame materials and reducing inventory requirements
Solution Approach 2:
The patent uses homogeneous material throughout - the frame is made from the same filter material as the filtration media, ensuring consistent properties and eliminating the need to manage multiple material types
2Ease of manufacture
If cardboard frames are used, then production cost is reduced, but water resistance is lost and frame durability decreases
Solution Approach 1:
The frame is made from the same water-resistant filter material as the media, ensuring the entire structure has uniform water resistance properties without requiring separate water-resistant materials
Solution Approach 2:
The filter material undergoes parameter changes through folding and adhesiving to transform from a flat sheet into a three-dimensional frame structure that maintains the original material's water-resistant properties
3Strength
If metal frames are used, then structural strength is improved, but disposal difficulty increases due to non-flammability
Solution Approach 1:
The entire filter assembly including the frame is made from the same combustible filter material, enabling uniform disposal through incineration without the complications of mixed materials
Solution Approach 2:
The frame is designed as a disposable component made from the same temporary filter material, intended to be discarded with the filter media after use rather than reused or recycled
4Ease of manufacture
If bag filters are used, then material cost is reduced, but structural stability decreases and contamination re-entry risk increases
Solution Approach 1:
The filter media is segmented into two functional portions: one portion forms the filtration surface while the other portion is folded and adhesived to create a rigid frame structure that provides structural stability
Solution Approach 2:
The frame and filter media are merged into a single integrated structure where the frame is formed directly from the filter material, eliminating the separate bag structure that causes collapse and contamination re-entry
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This approach reduces production costs, simplifies inventory management, and enables flexible production of various shapes and sizes, ensuring structural stability and safe disposal while maintaining cost-effectiveness and water resistance.
Implementation Method 1
a frame for the filter media which in one embodiment preferably comprises filter material impregnated with adhesive

AI summary
A filter pack includes filter media formed into a filter structure having a front, a back and at least one side surface; and a frame adhered to the at least one side surface and comprising an adhesive and an adhesive carrier. The adhesive carrier can be a sheet of material which can be impregnated with the adhesive, one example being a sheet of the filter material itself. The adhesive carrier can alternatively be a single use tray mold for holding the adhesive while it cures, and which is left into the final product.
