Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If filter elements are made robust and reliable for demanding operating conditions, then particle separation performance improves, but manufacturing cost and assembly complexity increase
Solution Approach 1:
The filter element is divided into modular components: a base support with attachment areas and multiple detachable attachments that can be independently assembled and disassembled. This segmentation allows for simplified assembly procedures while maintaining structural robustness through standardized connection elements at the fold edges.
Solution Approach 2:
The attachments are designed to be detachable and replaceable, transforming a static filter structure into a dynamic system where components can be easily assembled, disassembled, and maintained. This dynamic design reduces assembly complexity while ensuring reliability through reusable standardized connections.
2Ease of manufacture
If filter elements are designed for easy assembly and maintenance, then manufacturing and repair costs decrease, but structural stability and particle separation efficiency may be compromised
Solution Approach 1:
By segmenting the filter into a base support and detachable attachments with standardized connection elements, the design enables easy assembly and maintenance while maintaining structural stability through precise geometric interlocking at the fold edges.
Solution Approach 2:
The connection elements are pre-designed with complementary geometries that ensure stable interlocking before assembly occurs. The fold edge structures are predetermined to provide rigid attachment points, ensuring structural stability is built into the design before the actual assembly process.
3Productivity
If passage openings are arranged to maximize particle separation, then separation efficiency improves, but the structural integrity of the base support decreases
Solution Approach 1:
The base support is segmented with passage openings arranged in offset patterns between first and second fold edges. This segmentation allows high particle separation efficiency through multiple passage rows while maintaining structural integrity by distributing openings across segmented zones connected by rigid fold edges.
Solution Approach 2:
Passage openings are arranged in multiple rows offset in the flow direction, utilizing the dimensional space between fold edges. This multi-row offset arrangement maximizes particle separation efficiency by creating multiple flow paths while the fold edge geometry maintains structural integrity across the segmented base support.
4Duration of action of stationary object
If filter elements are designed as washable and regenerable, then operational duration increases, but the complexity of cleaning and maintenance procedures increases
Solution Approach 1:
The detachable attachment design segments the filter into easily separable components that can be independently removed and washed. This segmentation simplifies maintenance procedures while enabling regenerable operation, as attachments can be quickly detached for cleaning without complex disassembly procedures.
Solution Approach 2:
The dynamic detachable design allows rapid assembly and disassembly for cleaning purposes.Attachments can be easily removed, washed, and reattached, transforming a potentially complex maintenance procedure into a simple dynamic operation that extends operational duration while maintaining ease of maintenance.

Function Achieved in This Case
The filter element effectively separates particles from the raw gas stream, retains its shape under various stresses, and allows for easy assembly and maintenance, ensuring robust and reliable performance while being cost-effective to manufacture and transport.
Implementation Method 1
the particle-laden exhaust air, i.e. the raw gas flow, is deflected due to the offset arrangement of the first and second passage openings in an intermediate flow space between the base support and the several attachments
Implementation Method 2
the particles in the raw gas flow with a higher density cannot follow this deflection process and therefore collect in the intermediate flow space
