Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If silver nitrate solution is used as diluent, then electrolyte analysis can be performed, but wastewater treatment is required causing increased treatment cost and time
Solution Approach 1:
The patent extracts the harmful silver nitrate component from the diluent system and replaces it with pure water. This eliminates the need for wastewater treatment while maintaining the dilution function necessary for electrolyte analysis, thus resolving the contradiction between measurement capability and environmental treatment burden.
Solution Approach 2:
The patent changes the chemical composition parameter of the diluent from silver nitrate solution to pure water. This parameter change eliminates the harmful effects requiring wastewater treatment while preserving the essential dilution function needed for accurate electrolyte concentration measurement.
2Object-affected harmful factors
If non-standardized pure water is used for dilution, then environmental burden is reduced, but measurement accuracy decreases due to interfering ions
Solution Approach 1:
The patent implements a feedback mechanism where the ion concentration of the pure water diluent is measured before use. Based on this measurement feedback, the system determines whether the water quality meets the required standards, and only proceeds with measurement when the ion concentration is within acceptable ranges, thus ensuring measurement accuracy while using environmentally friendly pure water.
Solution Approach 2:
The patent performs preliminary measurement of the pure water's ion concentration before using it for dilution. This preliminary action ensures that the water quality meets the required standards, preventing measurement errors caused by interfering ions while maintaining the environmental benefits of using pure water instead of silver nitrate solution.
3Device complexity
If system water ion concentration is not monitored, then device complexity is reduced, but measurement reliability decreases due to undetected interfering ions
Solution Approach 1:
The patent makes the electrolyte analysis device multi-functional by integrating both the electrolyte concentration measurement function and the pure water ion concentration monitoring function into a single system. This universal approach allows the device to automatically monitor water quality and adjust or alert when ion concentrations affect measurement reliability, without requiring a completely separate monitoring system.
