Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If high levels of abrasive particles are used to achieve good cleaning performance, then cleaning efficacy is improved, but surface damage increases and formulation cost increases
Solution Approach 1:
The patent changes the physical parameters of abrasive particles by bleaching them to achieve a whiteness level (L*) greater than 65. This parameter change allows the use of lower particle concentrations (reducing surface damage and cost) while maintaining effective cleaning performance, as the bleached particles are more visible and aesthetically acceptable at lower levels.
Solution Approach 2:
The patent uses natural abrasive particles (nut shell, vegetable particles, wood particles) that can be obtained from renewable sources. These particles are designed to be effective at low concentrations and are replaced after use, avoiding the accumulation of residual particles that would require expensive surface restoration.
2Object-affected harmful factors
If natural abrasive particles are used to improve surface safety, then surface damage is reduced, but aesthetic appearance deteriorates due to brownish color
Solution Approach 1:
The patent applies color change technology by bleaching natural abrasive particles to achieve a whiteness level (L*) greater than 65. This transforms the original brownish color of natural particles into a white appearance, improving aesthetic acceptance and visibility in the cleaning liquid while maintaining the gentle surface properties of natural abrasives.
Solution Approach 2:
The patent uses strong oxidizing agents (such as hydrogen peroxide, sodium hypochlorite, or potassium percarbonate) to bleach the natural abrasive particles. This oxidation process removes the brownish coloration from the particles, transforming them into white particles that are aesthetically acceptable and highly visible in the cleaning composition.
3Illumination intensity
If bleached abrasive particles are used to improve aesthetics, then visual appearance is improved, but manufacturing complexity increases
Solution Approach 1:
The patent employs self-service by using the bleaching agent (such as hydrogen peroxide or sodium hypochlorite) that is already a core ingredient in the cleaning composition to simultaneously bleach the abrasive particles. This eliminates the need for a separate pre-bleaching step, as the particles are bleached in-situ during the formulation process, reducing manufacturing complexity while achieving the desired white appearance.
4Productivity
If high levels of abrasive particles are used to achieve good cleaning performance, then cleaning efficacy is improved, but formulation cost and rinse difficulty increase
Solution Approach 1:
The patent changes the optical parameters of abrasive particles through bleaching, achieving a whiteness level (L*) greater than 65. This parameter change increases the visibility and aesthetic acceptance of the particles, allowing effective cleaning performance to be achieved at lower particle concentrations, thereby reducing formulation cost and rinse burden.
