Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of substance
If conventional water treatment and conservation methods are used, then water consumption is reduced to some extent, but the reduction is inadequate to meet growing global demand and prevent shortages
Solution Approach 1:
The patent changes the physical parameters of water by applying flow-induced particle migration to separate contaminants based on size and shape. This physical separation method transforms the water from a contaminated state to a purified state, enabling effective recycling and significantly reducing fresh water consumption while ensuring adequate water supply for non-potable uses.
Solution Approach 2:
The patent recovers and recycles greywater that would otherwise be discarded. By implementing a treatment system that separates particles from greywater, the system enables reuse of this water for toilets and irrigation, transforming waste water into a valuable resource and dramatically reducing overall water consumption.
2Loss of substance
If greywater is recycled and reused, then water consumption is significantly reduced, but contaminants must be effectively removed to ensure water quality
Solution Approach 1:
The patent replaces conventional mechanical filtration systems with flow-induced particle migration technology. This approach uses fluid dynamics and particle physics rather than mechanical barriers, achieving effective contaminant separation without the maintenance and replacement issues associated with mechanical filters while ensuring water quality for reuse.
Solution Approach 2:
The patent changes the physical state and properties of particles in greywater through flow-induced migration. By manipulating flow parameters and particle behavior, the system effectively separates contaminants based on their physical characteristics, achieving high removal efficiency without mechanical filtration.
3Measurement precision
If flow-induced particle migration technology is used for particle separation, then particle separation based on size and shape is achieved without density dependence, but the system complexity increases
Solution Approach 1:
The patent implements a self-service system where flow-induced particle migration automatically separates particles based on their size and shape characteristics. The system uses the natural physical behavior of particles in flow to achieve separation without requiring complex control mechanisms or external intervention, thereby reducing operational complexity while maintaining high separation precision.
4Object-affected harmful factors
If conventional filtration systems are used, then particles are removed from water, but maintenance and replacement are required
Solution Approach 1:
The patent replaces mechanical filtration systems that require maintenance and replacement with flow-induced particle migration technology. This substitution eliminates the need for physical filters that clog and require upkeep, achieving particle removal through fluid dynamics alone and significantly improving ease of operation by eliminating maintenance requirements.
