Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a borate buffer system is used to control pH in chlorinated water, then pH stability is improved, but the system fails to control other problems such as excessive buffering agent requirements and increased maintenance
Solution Approach 1:
The invention changes the pH parameter of the cyanuric acid salt from conventional high pH (7.0-9.0) to a lower pH range (5.8-7.3). This parameter change allows the cyanuric acid salt to provide both pH buffering and cyanuric acid functionality simultaneously, reducing the need for separate borate buffer systems and decreasing the total quantity of buffering agents required in the water.
Solution Approach 2:
The invention makes the cyanuric acid salt serve multiple functions: it provides cyanuric acid for chlorine stabilization, acts as a pH buffering agent, and contributes to overall water stability. This multi-functionality eliminates the need for separate dedicated buffer systems, reducing the total substance quantity while maintaining pH control.
2Reliability
If conventional cyanuric acid salts with high pH are used, then chlorine stabilization is achieved, but dissolution rate is slow and excessive buffering agents are required
Solution Approach 1:
The invention changes the pH parameter of the cyanuric acid salt to a lower range (5.8-7.3), which significantly improves the dissolution rate while maintaining adequate chlorine stabilization capability. The optimized pH balance allows faster dissolution without sacrificing the reliability of chlorine stabilization.
3Reliability
If pH is not properly controlled in the range of 7-8, then chlorine effectiveness and stability are reduced, but maintaining this range requires excessive buffering agents and increased maintenance
Solution Approach 1:
The cyanuric acid salt serves dual purposes: stabilizing chlorine and buffering pH within the optimal 7-8 range. This multi-functionality maintains chlorine effectiveness while reducing maintenance requirements by eliminating the need for separate buffer system management and reducing the frequency of pH adjustments.
Solution Approach 2:
By optimizing the pH parameter of the cyanuric acid salt to (5.8-7.3), the invention enables the substance to automatically buffer the water pH within the optimal 7-8 range, maintaining chlorine effectiveness while minimizing maintenance intervention.
