Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If very hard abrasive particles are used to achieve good cleaning performance, then cleaning effectiveness is improved, but surface damage increases
Solution Approach 1:
The patent changes the physical parameters of the abrasive particles by using expanded perlite with specific particle size ranges (d10: 10-50 μm, d50: 25-350 μm, d90: 45-450 μm) and spherical morphology, transforming the abrasive from traditional sharp-edged particles to gentle spherical particles that provide cleaning action without surface damage
Solution Approach 2:
The patent creates a composite cleaning system by combining expanded perlite particles with detergent base and optional surfactants, forming a composite composition that achieves both cleaning effectiveness and surface safety through the synergistic interaction of the abrasive particles and cleaning agents
2Productivity
If plastic micro-beads are used to provide scrubbing action, then cleaning performance is improved, but environmental harm increases
Solution Approach 1:
The patent replaces persistent plastic micro-beads with biodegradable expanded perlite particles that provide the necessary scrubbing action for cleaning performance but decompose naturally in the environment, eliminating the long-term environmental accumulation problem associated with plastic micro-beads
Solution Approach 2:
The patent converts the previously harmful plastic micro-bead material into a beneficial biodegradable alternative by using expanded perlite, which provides equivalent cleaning functionality while its natural decomposition transforms it from an environmental pollutant to an environmentally friendly cleaning agent
3Object-affected harmful factors
If natural abrasive particles are used to provide gentle scrubbing, then surface safety is improved, but aesthetic appearance worsens due to dark color
Solution Approach 1:
The patent changes the optical parameters of the abrasive particles by using expanded perlite with specific particle size distributions and spherical morphology, which reflect and scatter light differently than dark natural particles, resulting in a lighter-colored composition that maintains surface safety while improving aesthetic appearance
