Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single shaft rod is used for transmission, then the device complexity is reduced, but vibration and noise increase during operation
Solution Approach 1:
The single shaft rod is segmented into multiple components: shaft rod, tubular chuck, bearing assembly, and spring. This segmentation allows each component to perform specific functions - the bearing assembly supports rotation while the spring dampens vibration, thereby reducing overall vibration and noise without excessive complexity increase
Solution Approach 2:
The bearing assembly acts as an intermediary between the shaft rod and the tubular chuck, providing a controlled interface that reduces direct contact and vibration transmission. The spring serves as another intermediary that absorbs and dampens vibrational energy, converting harmful vibrations into manageable elastic deformation
2Ease of operation
If the grinding head contacts the nail surface, then polishing function is achieved, but vibration and noise increase causing shaft shaking
Solution Approach 1:
The spring is pre-installed in the transmission structure to provide cushioning before vibration occurs. When the grinding head contacts the nail surface and generates vibration, the spring is already in position to absorb and dampen these vibrations, preventing shaft shaking and maintaining stability during the polishing operation
Solution Approach 2:
The spring changes the dynamic parameters of the transmission system by introducing elasticity and damping. This parameter change allows the system to absorb vibrational energy and maintain stable operation during grinding, preventing excessive vibration and noise while preserving the polishing function
3Object-generated harmful factors
If vibration reduction components are added, then vibration and noise are reduced, but device complexity increases
Solution Approach 1:
The tubular chuck serves multiple functions: it acts as a structural component for mounting the grinding head, provides a bearing surface for rotation, and works with the spring to dampen vibrations. This multi-functionality reduces the need for separate dedicated vibration reduction components, thereby limiting the increase in device complexity while still achieving vibration reduction

AI summary
Provided is a mill transmission device. In the mill transmission device, an output end of a motor is provided with a cross column that is the same as that at a top of a connecting shaft rod, and the cross column at the output end of the motor is inserted into a first connection port A, which drives a shaft tube to rotate. A rubber ring A embedded in the first connection port A is capable of reducing vibration and noise caused by rotation. Similarly, the shaft tube is detachably connected to the connecting shaft rod through a second connection port B and a rubber ring B, and the rubber ring B is also capable of reducing the noise and vibration caused by rotation of the shaft tube.
