Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If common washing powder is used to generate bubbles, then washing effect is improved, but large bubbles and excessive foam are generated making rinsing difficult
Solution Approach 1:
The patent changes the physical parameters of bubbles by using electrolysis to generate ultra-micro bubbles (0.01-0.1mm diameter) instead of conventional large bubbles. This parameter change in bubble size fundamentally improves washing effectiveness while eliminating the rinsing difficulty caused by excessive foam.
Solution Approach 2:
The patent replaces mechanical bubble generation methods (high-pressure spray, ultrasonic waves) with an electrochemical system. By using electrolysis of water through a porous membrane, the system generates bubbles through chemical reaction rather than mechanical force, achieving finer bubbles with better control.
2Reliability
If a large amount of detergent is used to improve washing quality, then washing effect is enhanced, but environmental pollution and residue on washed objects increase
Solution Approach 1:
The patent extracts and eliminates the need for conventional detergents from the washing system. By using electrolysis-generated active oxygen and ultra-micro bubbles, the system achieves washing quality without relying on chemical detergents, thereby removing the source of environmental pollution and residues.
Solution Approach 2:
The patent employs strong oxidants generated through electrolysis (active oxygen, ozone) as the active washing agent instead of conventional detergents. This oxidation-based washing mechanism effectively removes contaminants without leaving harmful residues and eliminates the need for excessive detergent usage.
3Object-generated harmful factors
If detergent-free washing with electrolysis is used, then environmental pollution is reduced, but sterilization function is single and cost performance is low
Solution Approach 1:
The patent enhances the versatility of the electrolysis system by integrating multiple functions: bubble generation for physical washing, active oxygen generation for oxidation/sterilization, and hydrochloric acid generation for acid treatment. This multi-functional approach eliminates the need for separate sterilization steps and improves cost performance.
Solution Approach 2:
The patent merges the sterilization function with the existing electrolysis washing process. By combining active oxygen generation, ozone production, and hydrochloric acid generation within the same electrolysis system, the patent achieves both washing and sterilization in one integrated process, improving adaptability and cost effectiveness.
4Ease of operation
If existing detergent-free washing machine with isolating membrane is used, then electrolysis is performed, but washing effect is undesirable due to single saponification function
Solution Approach 1:
The patent segments the electrolysis process into distinct functional zones: a cathode region generating hydrogen and hydroxide ions, and an anode region generating active oxygen and ozone. The porous membrane separates these regions while allowing ion exchange, enabling multiple washing mechanisms to operate simultaneously and improve overall washing effect.
Solution Approach 2:
The patent uses composite material structures including porous membranes with specific pore sizes (0.01-0.1mm) and electrode materials (platinum-coated titanium oxide) to optimize the electrolysis process. This composite approach enhances both the physical bubble generation and chemical oxidation reactions, significantly improving washing effectiveness.
