Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If pleated filter media with sharp-edged filter folds are used, then the filter medium can be compact and efficient, but the filter medium bends and deforms under high pressure
Solution Approach 1:
The filter medium is divided into multiple pleats separated by support profiles. Each pleat is an independent segment supported by rod-shaped profiles, preventing the entire structure from bending under pressure while maintaining the compact pleated design for efficient filtration.
Solution Approach 2:
Rod-shaped support profiles are introduced as intermediary elements between the filter medium and the housing. These support profiles bear the mechanical load and prevent the filter medium from deforming under high pressure, while allowing the filter medium to maintain its pleated structure for efficient particle separation.
2Reliability
If support profiles are added to stabilize the filter medium, then deformation is prevented, but the device complexity increases
Solution Approach 1:
The filter medium is designed as a flexible pleated structure that wraps around rod-shaped support profiles. This combination allows the filter medium to maintain its shape and structural stability without requiring a rigid housing structure, reducing overall device complexity while ensuring reliability.
Solution Approach 2:
Instead of adding support in the same plane as the filter folds, rod-shaped support profiles are positioned at multiple levels or rows within the housing, creating three-dimensional support structure. This spatial arrangement provides stabilization with minimal interference to the filter medium's function and reduces the number of support elements needed.
3Ease of operation
If the filter medium is clamped between support profiles, then easy replacement is enabled, but the filter medium may deform at clamping points
Solution Approach 1:
The filter medium is designed as a flexible pleated structure that naturally clamps itself against the rod-shaped support profiles through elastic restoring forces. This self-clamping mechanism enables easy replacement without additional fixing agents while maintaining filter medium integrity through the material's inherent elasticity.
Solution Approach 2:
The filter medium's own elastic properties are utilized to create the clamping force against the support profiles. The filter medium develops restoring forces against deformation and clamps itself against the support profiles, eliminating the need for external clamping mechanisms and simplifying replacement while preserving integrity.
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
The design effectively prevents deformation and ensures uniform airflow, reducing clogging and pressure loss while allowing for easy replacement and disposal of the filter medium.
Implementation Method 1
A surface filter medium (11) is arranged in the housing box (2), which has a plurality of filter pleats (12) for separating the paint and/or varnish residues
Implementation Method 2
The filter module (1) has a number of parallel support profiles (7), e.g., rod-shaped support profiles, to which the filter medium (11) is attached. This stabilizes the shape of the filter module (1)
Implementation Method 3
Above a certain filter thickness, the filter medium develops restoring forces against deformation, so that it clamps itself against the support profiles even without additional fixing agents
