Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional filtration methods are used to purify drinking water and alcohol beverages, then impurities can be removed, but the membranes and filters become clogged and their lifespan is shortened
Solution Approach 1:
The patent applies preliminary cavitation treatment to the liquid before it enters the filtration system. This pre-treatment breaks down impurities and reduces their concentration, preventing them from clogging the membranes and filters during subsequent filtration. As a result, the filtration system maintains high efficiency for a longer duration without requiring frequent cleaning or replacement.
Solution Approach 2:
The patent changes the physical parameters of the liquid by applying cavitation, which alters the size, concentration, and nature of impurities. This transformation of impurity characteristics prevents them from adhering to and clogging the filtration membranes, thereby extending the operational life of the filtration system while maintaining its effectiveness.
2Reliability
If conventional purification methods are used, then some impurities can be removed, but chemical and microbiological impurities remain and organoleptic qualities are suboptimal
Solution Approach 1:
The cavitation process generates strong oxidative effects that destroy chemical and microbiological impurities. The mechanical stress and temperature changes during cavitation promote oxidation reactions that eliminate harmful substances, achieving more thorough purification than conventional methods while improving the organoleptic qualities of the treated liquid.
Solution Approach 2:
The patent utilizes mechanical vibration and shock waves generated by cavitation to physically disrupt and remove impurities from the liquid. This mechanical action, combined with the chemical effects of cavitation, provides comprehensive purification that addresses both chemical and microbiological contaminants, resulting in superior organoleptic properties.
3Productivity
If filtration systems operate continuously to maintain high throughput, then productivity is improved, but clogging occurs more rapidly and system reliability decreases
Solution Approach 1:
By applying cavitation treatment before filtration, the system prepares the liquid in advance to prevent impurity accumulation on the membranes. This pre-treatment enables continuous operation at high throughput without the membranes becoming clogged, thereby maintaining both high productivity and system reliability simultaneously.
Solution Approach 2:
The patent enables continuous filtration operation by preventing clogging through prior cavitation treatment. The system can operate uninterrupted without requiring periodic cleaning or maintenance, achieving both high productivity through continuous operation and high reliability through sustained performance without degradation from clogging.

AI summary
A system and method of the purification of drinking water, ethanol and alcohol beverages is based on the action of hydrodynamic cavitation processing of microbiological and chemical contaminants, micro particles and colloidal particles. The fluid flow moves at a high rate through a multi-stage cavitation device and filtration module to generate hydrodynamic cavitation features in the fluid flow. The cavitation features generate changes in the velocity, pressure, temperature, chemical composition and physical properties of the liquid. The cavitation features also prevent the deposition of contaminants upon and remove contaminants from the surface of the filter module, reduce the load on the filter elements and increase the life of the filter module.
