Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If process chemicals are continuously added to stabilize treatment fluid, then microbial contamination is reduced, but chemical degradation increases and excessive chemical usage occurs
Solution Approach 1:
The patent implements a closed-loop feedback system where concentration measuring sensors continuously monitor the actual concentration of process chemicals in the treatment fluid. This measurement is fed back to a control device that automatically adjusts the dosing rate of process chemicals to maintain optimal concentration, preventing both under-dosing and over-dosing. This resolves the contradiction by enabling precise chemical addition only when needed, rather than continuous addition that causes degradation and waste.
Solution Approach 2:
The patent changes the operational parameter from continuous chemical addition to demand-based addition controlled by real-time concentration monitoring. By using sensors to detect actual chemical concentrations and adjusting dosing accordingly, the system maintains effective stabilization while minimizing chemical degradation and excessive usage.
2Quantity of substance
If fresh water is continuously added to replace lost treatment fluid, then fluid loss is compensated, but chemical concentration dilution occurs
Solution Approach 1:
The feedback control system continuously monitors chemical concentration and automatically compensates for dilution effects when fresh water is added. The control device adjusts the dosing rate based on real-time concentration measurements, ensuring that optimal chemical concentration is maintained despite volume changes from fresh water addition.
Solution Approach 2:
The patent maintains continuous monitoring and adjustment of chemical concentrations to ensure uninterrupted effective stabilization. The system continuously compensates for dilution by adjusting chemical dosing, ensuring that the treatment fluid remains effective at all times despite continuous fresh water addition.
3Ease of operation
If time-controlled or volume-controlled chemical addition is used, then dosing is simplified, but precise concentration control is lost
Solution Approach 1:
The patent replaces simple time-controlled or volume-controlled dosing with a feedback-controlled system that uses concentration measuring sensors to automatically adjust dosing rates. This maintains ease of operation through automated control while achieving precise concentration accuracy that manual or simple programmable systems cannot provide.
