Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If water absorbent resin particles are used in sanitary materials, then water absorption capacity is improved, but water absorption amount under load deteriorates
Solution Approach 1:
The patent applies mechanical vibration by shaking the powder containing water absorbent resin particles in a container. This vibration treatment modifies the particle structure or surface properties, enabling the resin to maintain high water absorption capacity while significantly improving water absorption performance under load conditions.
2Reliability
If water absorbent resin particles are subjected to complex treatment processes, then water absorption amount under load is improved, but manufacturing complexity increases
Solution Approach 1:
The patent changes the physical state or surface parameters of the water absorbent resin particles through shaking treatment. This simple parameter change approach achieves improved water absorption under load without requiring complex multi-step manufacturing processes, maintaining ease of production while enhancing performance.
