Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a conical grinding wheel grinding system is used, then grinding power control and fineness uniformity are improved, but device complexity and volume increase
Solution Approach 1:
The grinding device is divided into detachable components: the grinding assembly (including conical grinding wheel, drive shaft, and drive gear) can be separated from the coffee machine body. This segmentation maintains the precision benefits of conical grinding while reducing operational complexity by allowing easy removal and cleaning of the grinding components without disassembling the entire device.
2Manufacturing precision
If a conical grinding wheel grinding system is used, then grinding power control and fineness uniformity are improved, but device volume increases
Solution Approach 1:
The drive shaft is positioned within the circumferential space around the transmission shaft, utilizing the available radial space efficiently. The grinding assembly components are nested concentrically, with the drive shaft surrounding the transmission shaft, maximizing space utilization and minimizing the overall device volume while maintaining conical grinding precision.
3Ease of operation
If the grinding device is made detachable for cleaning, then ease of cleaning is improved, but transmission connection complexity increases
Solution Approach 1:
The drive gear is extracted as a separate component that can be easily detached from the drive shaft. This allows the grinding assembly to be completely removed from the coffee machine body for cleaning without requiring disassembly of the transmission connection mechanisms, maintaining simple and reliable power transmission while enabling easy maintenance.
