Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a peroxide-based cleaning formulation is used to achieve strong cleaning and bleaching performance, then cleaning effectiveness is improved, but formulation stability and shelf life deteriorate due to pH variability
Solution Approach 1:
The patent applies parameter changes by implementing a two-component buffer system that maintains pH within a specific range (2.0-2.5 for non-diluted and 2.5 for diluted formulations). This pH control stabilizes the peroxide-based formulation, preventing degradation while preserving cleaning effectiveness. The buffer system uses a weak acid and its conjugate base to resist pH changes during storage and use.
2Productivity
If the formulation strength is increased to improve cleaning performance, then cleaning power is enhanced, but corrosiveness to metal surfaces increases
Solution Approach 1:
The patent controls the pH parameter within a narrow range (2.0-2.5) using a two-component buffer system. This pH optimization balances cleaning power with metal surface safety. The buffer system prevents excessive acidity that would cause corrosion while maintaining enough acidity for effective cleaning and bleaching performance.
3Object-affected harmful factors
If the formulation is diluted to reduce corrosiveness and improve safety, then safety is improved, but pH stability becomes more difficult to maintain
Solution Approach 1:
The patent designs a buffer system that maintains pH stability across different dilution levels. The two-component buffer (weak acid and conjugate base) is formulated to provide adequate buffering capacity both in concentrate and diluted forms. Testing shows the system maintains pH 2.0-2.5 in non-diluted and pH 2.5 in diluted formulations, ensuring safety and stability simultaneously.
4Adaptability or versatility
If multiple active ingredients and adjuncts are included to enhance formulation versatility, then functional performance is improved, but color stability and odor control deteriorate
Solution Approach 1:
The patent uses pH control through a two-component buffer system to stabilize colorants and fragrances in the formulation. By maintaining pH within the 2.0-2.5 range, the buffer prevents degradation of colorants and odor compounds, ensuring color stability and odor control while allowing multiple active ingredients and adjuncts for enhanced functional performance.
