Spiral-Wrapped Air Filter Frame with Reinforcing Strut
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional framed air filters lack structural rigidity and resistance to deformation, particularly in air-handling systems, due to their design which can lead to inefficiencies in filtration and potential air leaks.
Innovation Solution
A framed air filter with a spiral-wrapped frame design, where each frame portion is formed from a single frame piece with foldably-connected segments, incorporating a terminal segment as a reinforcing strut to enhance structural integrity and resistance to twisting and crushing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional framed air filters are used, then the device is simple to manufacture, but the structural rigidity and resistance to deformation are insufficient
Solution Approach 1:
The terminal segment of the spiral-wrapped frame piece is nested within the interior space of the frame portion, where it provides reinforcing strut functionality. This nesting arrangement allows the frame to achieve enhanced structural rigidity without adding external components, as the reinforcing element is integrated within the existing frame structure.
Solution Approach 2:
The frame piece is configured in a spiral-wrapped configuration, using curved geometry to provide structural strength. The spiral shape inherently resists deformation and twisting forces better than straight segments, while the curvature allows the terminal segment to effectively serve as a diagonal reinforcing strut across the frame portion.
2Area of stationary object
If the frame structure is simplified, then the manufacturing is easier, but the active filtration area is reduced
Solution Approach 1:
The terminal segment of the frame piece serves multiple functions: it forms part of the frame structure, provides reinforcing strut support, and contributes to the overall structural rigidity. This multi-functionality eliminates the need for separate reinforcing components, maintaining manufacturing simplicity while maximizing the active filtration area.
Solution Approach 2:
The reinforcing strut function is merged with the frame piece itself rather than being a separate component. The terminal segment of the same frame piece that forms the frame perimeter also serves as the reinforcing element, combining structural support and frame formation into a single integrated component.
3Reliability
If conventional frame designs are used, then the manufacturing process is straightforward, but the resistance to twisting and crushing is insufficient
Solution Approach 1:
The terminal segment is positioned within the interior space of the frame portion, nested among the other frame segments. This nested arrangement allows the reinforcing strut to effectively brace the frame structure against twisting and crushing forces while maintaining a compact, integrated design without additional external components.
Solution Approach 2:
The spiral-wrapped configuration of the frame piece provides inherent resistance to deformation. The curved, spiral geometry distributes mechanical stresses more effectively than straight segments, enhancing the frame's ability to resist twisting and crushing forces while maintaining structural integrity.
