Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If electrolysis technique is used for water treatment, then disinfection and organic matter oxidation are achieved, but salt addition and periodic replenishment are required
Solution Approach 1:
The patent combines electrolysis and UV radiation techniques in a single reactor system. The electrolysis component generates chlorine for disinfection and oxidation, while the UV radiation component destroys chloramines that would otherwise require salt replenishment. This merging allows the system to maintain disinfection effectiveness while eliminating the need for periodic salt addition, as the UV destruction of chloramines prevents the buildup that would require filter washing and salt replenishment.
Solution Approach 2:
The patent changes the operational parameters by introducing UV radiation dosage as an additional control variable alongside electrolysis current. By adjusting the UV radiation intensity and exposure time, the system optimizes chloramine destruction efficiency, which in turn maintains stable salt concentrations without requiring periodic replenishment while preserving disinfection effectiveness.
2Reliability
If electrolysis technique is used for water treatment, then disinfection is achieved, but pH increase requires continuous addition of pH reducer
Solution Approach 1:
The patent merges electrolysis with UV radiation in a single reactor, where the UV component addresses the pH control issue by destroying chloramines that form during electrolysis. This combination reduces the need for continuous pH adjustment, as the UV treatment mitigates the formation of compounds that would otherwise require chemical intervention for pH management.
3Quantity of substance
If UV radiation technique is used for water treatment, then no salt addition is required, but no residual disinfection or organic matter oxidation capacity is provided
Solution Approach 1:
The patent combines UV radiation with electrolysis in a single reactor system. The electrolysis component provides residual disinfection through generated chlorine and oxidizes organic matter, while the UV component ensures no salt addition is needed by destroying chloramines. This merging allows the system to simultaneously achieve residual disinfection, organic matter oxidation, and elimination of salt replenishment requirements.
Solution Approach 2:
The patent changes the system parameters by introducing both electrolysis current and UV radiation dosage as controllable variables. By optimizing the electrolysis current to generate sufficient chlorine for residual disinfection and organic matter oxidation, while simultaneously applying UV radiation to prevent chloramine accumulation, the system achieves both disinfection reliability and elimination of salt addition requirements.
4Reliability
If both electrolysis and UV radiation are applied separately, then各自的 advantages are obtained, but multiple reactors and complex system are required
Solution Approach 1:
The patent merges electrolysis and UV radiation techniques into a single integrated reactor design. The reactor contains both electrolysis electrodes and UV radiation lamps within the same treatment chamber, allowing simultaneous application of both techniques. This integration maintains the treatment effectiveness of both methods while significantly reducing system complexity compared to separate reactors, as it eliminates the need for multiple independent treatment units and reduces piping, control systems, and maintenance requirements.
