Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a filter membrane is used to remove minute matters, then filtering accuracy is improved, but the filter membrane becomes clogged and requires frequent cleaning or replacement
Solution Approach 1:
The filter device is divided into two independent chambers: a filtering chamber containing the filter membrane for accurate filtration, and a cleaning chamber for washing the membrane. This segmentation allows the filtering function and cleaning function to operate independently, preventing clogging from affecting filtering accuracy while enabling easy membrane maintenance without disassembly.
Solution Approach 2:
A cleaning liquid circulation system acts as an intermediary between the filtering chamber and the external environment. The cleaning liquid flows through the filter membrane from the cleaning chamber, removing accumulated particles without requiring disassembly. This intermediary mechanism solves the contradiction by providing a reliable cleaning path that maintains filtering accuracy while preventing clogging.
2Ease of operation
If the filter device is disassembled to clean the filter membrane, then cleaning effectiveness is improved, but operational complexity increases
Solution Approach 1:
The cleaning chamber and filtering chamber are merged into a single integrated device body with a partition wall. The cleaning chamber contains all necessary cleaning components (liquid supply, circulation path) and directly accesses the filter membrane through the partition wall. This merging allows effective cleaning to be performed without disassembly, eliminating the contradiction between cleaning effectiveness and operational complexity.
Solution Approach 2:
The filter membrane performs self-cleaning by allowing cleaning liquid to pass through it from the cleaning chamber. The membrane's own structure is utilized as the cleaning path, eliminating the need for external disassembly operations. This self-service mechanism resolves the contradiction by making the membrane accessible for cleaning while maintaining the integrity of the overall device structure.
3Reliability
If disposable filter membranes are used to avoid clogging, then reliability is improved, but operational cost increases
Solution Approach 1:
Instead of discarding the filter membrane after use, the device recovers it by enabling repeated cleaning cycles. The cleaning chamber allows the membrane to be washed and reused multiple times while maintaining its filtering performance. This recovery mechanism resolves the contradiction by preserving the membrane's reliability while eliminating the need for continuous replacement, thereby reducing operational costs.
