Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If polymer solid particles are used as washing medium, then washing effectiveness is improved, but separation difficulty increases
Solution Approach 1:
The patent changes the physical state parameter of the polymer solid particles from wet to dry through dehydration treatment. This parameter change causes the particles to detach from the clothing surface, resolving the separation difficulty while maintaining washing effectiveness. The dehydration process transforms the adhesive state into a separable state.
Solution Approach 2:
The patent introduces dynamic separation processes including centrifugal separation and filtration operations that actively move the polymer particles from the clothing. This dynamic approach converts the static adhesion problem into a dynamic separation solution, enabling easy recovery of washing medium.
2Productivity
If polymer solid particles adsorb on clothes surface, then washing capability improves, but particle recovery becomes difficult
Solution Approach 1:
The patent applies dehydration to change the moisture parameter of the polymer particles, transforming them from an adsorbed wet state to a dry recoverable state. This parameter change enables complete particle recovery without loss, solving the substance retention problem while preserving washing capability.
Solution Approach 2:
The patent replaces manual separation methods with automated mechanical separation systems including centrifugal separators and filtration devices. This substitution enables efficient particle recovery without material loss, converting the recovery difficulty into an automated solution.
3Ease of operation
If dehydration is applied to separate particles, then separation ease improves, but energy consumption increases
Solution Approach 1:
The patent segments the dehydration process into multiple stages: initial dehydration during washing, followed by centrifugal separation, and final filtration. This segmentation distributes the energy requirement across different phases, reducing peak energy consumption while maintaining separation effectiveness.
Solution Approach 2:
The patent employs periodic dehydration cycles interspersed with washing phases. This periodic action allows energy-intensive dehydration to occur in controlled intervals rather than continuously, optimizing energy utilization while achieving complete particle separation.
