Solution Overview
Problem
Conventional machine dishwashing detergents face challenges in achieving effective cleaning and rinsing performance, particularly at low temperatures (50 °C or below) and in short-duration cycles, especially when dealing with bleachable stains like tea stains.
Innovation Solution
The use of shaped dishwashing detergents containing polyvinylpyrrolidone particles and a bleach catalyst, which are designed to improve cleaning performance by facilitating disintegration and enhancing bleaching action, even in low-temperature and short-cycle processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If conventional machine dishwashing detergents are used, then cleaning performance is achieved, but cleaning effectiveness deteriorates in low-temperature cycles (50°C or below) and short-duration processes
Solution Approach 1:
The patent changes the chemical parameters of the detergent by incorporating polyvinylpyrrolidone particles with specific particle sizes (100-150 μm) and using enhanced bleach catalyst systems. These parameter changes allow the detergent to maintain effective cleaning performance at lower temperatures (50°C or below) and in shorter washing cycles, resolving the contradiction between temperature reduction and cleaning effectiveness maintenance.
2Productivity
If washing time is reduced to create short-duration cleaning processes, then productivity increases, but cleaning performance deteriorates
Solution Approach 1:
The polyvinylpyrrolidone particles are incorporated into the detergent formulation in advance to prepare the cleaning system for rapid action. These particles facilitate faster disintegration and release of cleaning agents, enabling effective cleaning performance to be achieved in reduced time periods (60 minutes or less), thus resolving the contradiction between washing speed and cleaning performance.
3Reliability
If polyvinylpyrrolidone particles are added to enhance disintegration, then cleaning performance improves, but device complexity increases
Solution Approach 1:
The polyvinylpyrrolidone particles serve multiple functions simultaneously: they act as disintegration aids to break down the detergent matrix, provide cleaning enhancement through their polymer structure, and facilitate the release of bleach catalysts. This multi-functionality allows the detergent composition to maintain improved cleaning performance without proportionally increasing complexity, as one additive performs multiple roles in the cleaning system.
