Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If grinding method is used to disintegrate substances into nano-dimension, then the substances can be processed into fine grains, but the grinding efficiency is low due to high probability of re-grinding and non-uniform grain sizes
Solution Approach 1:
The patent replaces the traditional mechanical grinding system with a pneumatic system using high-speed airflow and a fluid mobility device. The airflow generates centrifugal force to disintegrate particles, eliminating the re-grinding problem and achieving more uniform grain sizes while improving processing efficiency
Solution Approach 2:
The patent changes the processing parameters by using controlled high-speed airflow velocity and pressure to disintegrate particles. By adjusting the airflow parameters, the system achieves consistent nano-sized particle production without the non-uniform grain sizes characteristic of mechanical grinding
2Productivity
If high-speed airflow and booster impeller are used to disintegrate substances, then the disintegration efficiency is improved, but the device complexity increases due to additional components
Solution Approach 1:
The patent designs the covering drum to serve multiple functions: it acts as both the housing for the high-speed airflow generation system and the separation device for nano-sized particles. The draining shaft also performs dual functions of driving the booster impeller and facilitating material discharge, thereby reducing overall device complexity while maintaining high disintegration efficiency
Solution Approach 2:
The patent combines the high-speed airflow generation system and the separation device into a single integrated covering drum structure. This merging of functions eliminates the need for separate components, reducing device complexity while achieving both efficient disintegration and particle separation
