Interchangeable Filter Coupling Frame for Variable Prefilters
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing filter coupling frames are limited to a single type of prefilter with a fixed header dimension, restricting their use to specific filtration arrangements and failing to optimize filtration systems for varying environmental or seasonal conditions.
Innovation Solution
A filter coupling frame with interchangeable couplings, including a frame body and releasable couplings that can engage upstream filters of different thicknesses and geometries, allowing for quick and easy replacement and adjustment to accommodate various filtration needs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed header dimension is used for the prefilter, then the filter coupling frame can be simplified in structure, but it limits the adaptability to different filter depths, shapes, and geometries
Solution Approach 1:
The filter coupling frame is divided into modular components: a frame body and multiple interchangeable couplings. Each coupling is designed to accommodate specific prefilter types, allowing the system to be segmented into standardized units that can be reconfigured based on filtration needs.
Solution Approach 2:
The frame body is designed as a universal platform that can accept different types of couplings. This multi-functional design allows a single frame body to support various prefilter configurations by simply changing the coupling component, thereby achieving adaptability without redesigning the entire structure.
2Adaptability or versatility
If only one type of prefilter is supported, then the filter coupling frame design can be simplified, but it fails to optimize filtration systems for different environmental or seasonal conditions
Solution Approach 1:
The interchangeable couplings are designed with varying parameters (dimensions, geometries, engagement mechanisms) to match different prefilter types required for specific environmental conditions. This allows the same frame body to be optimized for different situations by changing the coupling parameters rather than manufacturing entirely different frame bodies.
3Reliability
If reusable couplings are used instead of disposable ones, then long-term cost and sustainability are improved, but the initial device complexity and manufacturing requirements increase
Solution Approach 1:
The coupling mechanisms are designed with self-latching or self-aligning features that enable automatic engagement and secure attachment without requiring complex external fastening systems. This self-service capability reduces the overall complexity of the coupling mechanism while ensuring reliable, reusable connections between the frame body and prefilters.
