Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional filtration devices are used to remove solid matters, then bulk filtration is achieved, but the devices are overwhelmed by large quantities of solid matters and iron rust in a short time
Solution Approach 1:
A magnetic field is introduced as an intermediary force between the paramagnetic contaminants (iron rust, polymeric sludge) and the filtration system. The magnetic field attracts and concentrates these contaminants toward the magnetic filter element, enhancing the removal efficiency and preventing overwhelm by large quantities of solid matters.
Solution Approach 2:
The patent replaces purely mechanical filtration with a hybrid system combining magnetic attraction and mechanical filtration. The magnetic field substitutes for part of the mechanical filtration workload by pre-concentrating paramagnetic contaminants, allowing the mechanical filter element to operate more efficiently and continuously.
2Ease of operation
If conventional filtration devices are used, then filtration is provided, but rejuvenation requires disassembly and replacement of filter elements which is costly and time-consuming
Solution Approach 1:
The magnetic filter element is designed to be easily removable and regenerable without complex disassembly. The strong magnetic attraction allows contaminants to be concentrated on the filter element, which can then be quickly regenerated by removing the magnetic field and flushing the accumulated contaminants away, enabling rapid rejuvenation.
Solution Approach 2:
The patent enables recovery and regeneration of the filter element by utilizing the magnetic field to concentrate contaminants for easy removal. The filter medium itself is not discarded but regenerated in place, reducing both time and cost associated with replacement.
3Productivity
If conventional filtration devices are used, then filtration is achieved, but contaminant build-up causes operational problems such as increased pressures and reduced flow rates
Solution Approach 1:
The magnetic field acts as an intermediary that continuously attracts paramagnetic contaminants toward the filter element, preventing them from building up in the bulk flow. This continuous magnetic attraction maintains steady flow rates and prevents pressure increases by actively managing contaminant distribution.
Solution Approach 2:
The magnetic field operates continuously to attract and concentrate paramagnetic contaminants as they pass through the filtration device. This continuous action prevents contaminant build-up that would otherwise lead to increased pressures and reduced flow rates, maintaining consistent operational performance.
