Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional hydrogel shredding devices do not provide uniform shredding of hydrogel particles, leading to non-uniform drying and subsequent issues in manufacturing superabsorbent polymers, such as overdried or undried grains, which affect the quality and physical properties of the final product.
Innovation Solution
A hydrogel shredding device with a first barrel body and a second barrel body positioned orthogonally or at an acute/obtuse angle, featuring a cutter member and a porous plate for uniform shredding, where the hydrogel is transferred in the gravitational direction to ensure consistent pressure and prevent backflow, improving the manufacturing quality of superabsorbent polymers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional chopper with horizontal moving direction is used, then the hydrogel can be transferred and cut, but the pressure on the porous plate is not uniform causing non-uniform shredding
Solution Approach 1:
The patent changes the moving direction from horizontal to vertical (gravitational direction), transforming the one-dimensional horizontal transfer into a multi-dimensional vertical transfer that utilizes gravity for uniform pressure distribution on the porous plate, thereby achieving uniform shredding while maintaining operational capability
2Device complexity
If non-uniform pressure is applied on the porous plate, then the chopper can operate with simple structure, but the hydrogel particles are not uniformly shredded leading to overdried or undried grains
Solution Approach 1:
The patent employs gravitational force as a self-service mechanism that automatically provides uniform pressure distribution on the porous plate without requiring complex external pressure control systems. The vertical moving direction allows gravity to naturally equalize pressure across the plate surface, achieving uniform shredding while maintaining structural simplicity
3Manufacturing precision
If the barrel extends vertically in gravitational direction, then uniform pressure is applied on the porous plate for uniform shredding, but the device occupies more vertical space
Solution Approach 1:
The patent reorients the barrel extension from horizontal to vertical dimension, utilizing the gravitational direction to achieve uniform pressure distribution. This dimensional change allows the system to achieve superior shredding uniformity by leveraging the natural gravitational force field rather than requiring extended horizontal space
