Universal Flange With Radial Projections For Filter Cartridge Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing filter cartridge fastening flanges are limited to a single mounting hole circle, requiring separate production and storage for different filter systems with varying hole circle requirements.
Innovation Solution
The design incorporates at least two radially projecting projections with open-edged recesses pointing in different circumferential directions, allowing for multiple mounting hole circle diameters, and optionally features stepped recesses for secure nut engagement and elastic deformation for adaptability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single flange design with fixed recess positions is used, then the manufacturing and storage costs are reduced, but the flange can only be used with one specific mounting hole circle diameter
Solution Approach 1:
The flange incorporates projections with recesses that can be positioned at multiple radial distances from the center, allowing the effective attachment pattern to dynamically adapt to different mounting hole circle diameters. This dynamic positioning capability enables a single flange design to accommodate multiple bolt circle configurations without requiring separate flange variants.
Solution Approach 2:
The flange is designed with multiple recess locations on its projections, making it a universal component that can interface with different mounting hole circle diameters. By incorporating recesses at varying radial distances, the single flange design serves multiple functions across different filter system configurations, eliminating the need for multiple specialized flange types.
2Reliability
If separate flanges are produced for different mounting hole circle diameters, then each flange is optimized for its specific application, but production costs and storage requirements increase
Solution Approach 1:
The invention merges the functionality of multiple specialized flanges into a single unified design. By combining multiple recess position options into one flange structure, the solution consolidates what would otherwise require separate manufacturing processes, tooling, and inventory management, thereby reducing production costs while maintaining secure attachment capabilities.
Solution Approach 2:
The universal flange design replaces multiple application-specific flanges, reducing the total number of parts that need to be manufactured and stored. This multi-functional approach maintains reliable attachment for different mounting hole circle diameters while significantly lowering manufacturing complexity and inventory requirements.
3Adaptability or versatility
If multiple projections with recesses at different radial distances are incorporated, then compatibility with different bolt circle diameters is achieved, but the projection structure becomes more complex
Solution Approach 1:
The flange's projection structure is segmented into distinct recess locations at different radial distances. Each segment or projection can independently engage with mounting holes at specific positions, allowing the overall structure to accommodate multiple pitch circle diameters through its modular, segmented geometry rather than requiring a completely different flange design.

AI summary
The flange fastener, especially for air filter cartridges, has at least two radial projections (18,18',18"), with elastic distortion, at the circumference of the flange (10) each with edge openings (20) in the same direction to hold the fastening bolts. The projections also have edge openings (20') in the opposite direction. The edge openings in different directions are at different radial distances from the flange center when they are distorted. The edge openings are axially stepped to hold a fastening nut in a positive fit.
