Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a single filter is used to purify contaminated water, then the filtration process is simple, but the filter becomes clogged quickly by suspended solids and requires frequent replacement or cleaning
Solution Approach 1:
The filter is divided into two separate filters with different mesh sizes (first filter with larger mesh, second filter with smaller mesh). Each filter handles different size particles, preventing any single filter from becoming completely clogged and extending the overall system service life while maintaining filtration efficiency.
Solution Approach 2:
The invention transitions from a single-filter system to a two-filter system with different mesh sizes, adding a dimensional aspect of filtration granularity. This multi-layer approach allows simultaneous handling of different particle sizes, improving both productivity and duration of action.
2Ease of operation
If pressure is applied in one direction to the filter, then the filtration process is simple, but suspended solids attach to only one side making long-term use difficult
Solution Approach 1:
The single-filter system is segmented into two filters arranged in series, each handling different particle sizes. This segmentation allows each filter to operate more efficiently without becoming rapidly clogged, extending service life while maintaining operational simplicity.
Solution Approach 2:
The invention introduces dynamic operation modes including forward filtration and backwashing cycles. The system can switch between filtering mode and backwashing mode, allowing periodic reversal of flow to clean the filters, thereby extending service life without complicating everyday operation.
3Reliability
If filters are replaced or cleaned frequently to maintain filtration efficiency, then filtration performance is maintained, but maintenance costs and environmental impact increase
Solution Approach 1:
The system implements periodic backwashing cycles instead of frequent filter replacement. During backwashing, the flow direction is reversed to dislodge and remove accumulated solids, allowing filters to be regenerated in place. This periodic maintenance approach maintains filtration efficiency while minimizing water loss and environmental impact compared to frequent replacement or conventional cleaning.
Solution Approach 2:
The backwashing function allows the filtration system to clean itself without external intervention or significant water loss. The system uses its own operational cycles to regenerate the filters, reducing the need for external cleaning processes and minimizing substance loss.
4Measurement precision
If a fine mesh filter is used to separate fine foreign substances, then filtration precision is improved, but the filter clogs more quickly with solid substances
Solution Approach 1:
The filtration function is segmented into two stages: the first filter with larger mesh handles coarse particles, while the second filter with smaller mesh handles fine particles. This segmentation protects the fine mesh filter from rapid clogging by larger solids, extending its service life while maintaining high separation precision for fine particles.
Solution Approach 2:
The first filter performs preliminary filtration of larger particles before water enters the second filter. This preliminary action removes the bulk of suspended solids that would otherwise quickly clog the fine mesh of the second filter, allowing it to maintain high separation precision for an extended period.
