Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If liquid acid is used in solid compositions, then acid functionality is provided, but water content increases and dimensional stability deteriorates
Solution Approach 1:
The patent uses solid acid fillers (such as calcium carbonate, silica, or alumina) as intermediary substances to replace liquid acid in the solid composition. These solid fillers provide the necessary acid functionality and buffering capacity without introducing excess water, thereby maintaining dimensional stability while delivering acid-based cleaning and sanitizing effects.
Solution Approach 2:
The invention changes the physical state parameter of the acid from liquid to solid form by using solid acid fillers. This parameter change allows the composition to maintain low water content and high dimensional stability while still providing the required acid functionality for cleaning and sanitizing applications.
2Stability of the object's composition
If urea and acid are combined in solid compositions, then solidification is achieved, but stability issues arise leading to dimensional instability
Solution Approach 1:
The patent creates a composite solid composition combining urea, solid acid fillers, and additional active components in a stable matrix. This composite structure ensures that the urea and acid coexist stably without causing dimensional instability, while maintaining the functionality of all components including quaternary ammonium compounds and surfactants.
Solution Approach 2:
Solid acid fillers serve as intermediary substances that mediate between urea and other active components in the composition. These fillers provide structural support and chemical stability, preventing unwanted reactions between urea and acid while maintaining dimensional stability of the solid composition during storage and use.
3Adaptability or versatility
If additional active components are added to urea/acid compositions, then functionality is enhanced, but interaction instability increases
Solution Approach 1:
Solid acid fillers act as intermediary substances that stabilize interactions between urea and additional active components such as quaternary ammonium compounds and surfactants. These fillers prevent unwanted chemical reactions and maintain the stability of the composition while allowing multiple functional components to coexist and work together effectively.
Solution Approach 2:
The invention formulates a stable composite material containing urea, solid acid fillers, and multiple active components including quaternary ammonium compounds and surfactants. This composite structure ensures compatibility and stability among all components while providing enhanced functionality for cleaning, sanitizing, and rinsing applications.
