Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a coarse grinding mechanism and a fine grinding mechanism are arranged with multiple trapezoid grinding rollers, then the grinding effect is improved, but the structure becomes complex and stability cannot be ensured at high speed
Solution Approach 1:
The grinding mechanism is divided into a coarse grinding section with first grinding teeth and a fine grinding section with second grinding teeth. The female grinding head includes a first portion for coarse grinding and a second portion for fine grinding, allowing different grinding stages to be performed in sequence within a single integrated structure.
Solution Approach 2:
The patent combines the coarse grinding and fine grinding functions into a single integrated grinding mechanism. The male grinding head rotates within the female grinding head, with both coarse and fine grinding teeth arranged on the same female grinding head, merging multiple grinding stages into one compact unit that maintains stability at high speeds.
2Power
If motors are provided in both upper and lower portions of the device, then grinding power is increased, but energy consumption increases and the device occupies more area and is heavier
Solution Approach 1:
The patent uses a single motor located in the housing to drive both the male grinding head and the female grinding head through a transmission mechanism. The motor's driving shaft connects to the male grinding head, which rotates within the female grinding head, eliminating the need for separate motors and reducing energy consumption while maintaining adequate grinding power.
Solution Approach 2:
A single motor performs multiple functions by driving both grinding heads through the rotational mechanism. The motor provides the necessary power for both coarse and fine grinding operations, making the motor a multi-functional component that reduces overall device complexity and energy usage.
3Device complexity
If the gap between male and female grinding heads is fixed, then the structure is simple, but particle size control is limited
Solution Approach 1:
The patent incorporates an adjustable mechanism that allows the gap between the male and female grinding heads to be dynamically changed. The female grinding head can be adjusted vertically relative to the male grinding head, enabling the user to control the particle size of ground material by varying the gap distance, thus providing adaptability while maintaining a relatively simple structure.
