Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a conventional chopper is used to cut hydrogel, then the cutting process can be performed, but uniform cutting is not achieved due to uneven pressure distribution
Solution Approach 1:
The patent introduces a pump unit that dynamically controls and uniformizes the pressure distribution on hydrogel particles during the cutting process. The pump unit adjusts the pressing force in real-time to ensure uniform pressure across all particles, transforming the static pressure application of conventional choppers into a dynamic, controllable process that achieves uniform cutting.
Solution Approach 2:
The patent changes the pressure parameter from uneven to uniform by introducing a pump unit that actively regulates the pressing force. By controlling the pump's output, the system maintains consistent pressure across all hydrogel particles, directly addressing the pressure distribution issue that prevents uniform cutting in conventional systems.
2Productivity
If non-uniform cutting occurs, then the cutting process is simpler, but non-uniform drying occurs during the drying process
Solution Approach 1:
The patent applies preliminary action by ensuring uniform cutting is achieved before the drying process begins. The pump unit guarantees uniform pressure distribution and cutting during the cutting stage, so that when drying occurs subsequently, all particles start with uniform size and surface area, preventing non-uniform drying and ensuring consistent product quality.
3Reliability
If excessive drying occurs, then fine powder is generated, but the preparing process becomes problematic
Solution Approach 1:
The patent utilizes hydraulic principles by employing a pump unit to control the fluid pressure and flow during the cutting and drying processes. The pump's hydraulic control enables precise regulation of pressure to prevent excessive drying and fine powder generation, while maintaining reliable operation throughout the preparing process.
