Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a tension pulley is added to control belt tension, then the belt tension can be maintained, but the structure becomes more complex and assembly becomes difficult
Solution Approach 1:
The patent combines the tension pulley with the motor mounting bracket, integrating two functions (belt tensioning and motor support) into a single component. This merging eliminates the need for a separate tension pulley assembly, thereby maintaining belt tension control while reducing structural complexity and easing assembly.
Solution Approach 2:
The motor mounting bracket is designed to serve multiple functions: supporting the motor, guiding the belt, and acting as a tension pulley. By making the mounting bracket universal, the patent achieves belt tension maintenance without adding dedicated tensioning components, thus avoiding increased structural complexity.
2Reliability
If manual adjustment of center distance is used to tension the belt, then the belt can be tensioned, but frequent disassembly and maintenance are required
Solution Approach 1:
The patent implements automatic belt tensioning through the elastic pressing member that continuously applies force to the tension pulley. This self-adjusting mechanism maintains optimal belt tension without requiring manual intervention or frequent disassembly for adjustment, thereby reducing maintenance frequency while ensuring reliable belt tension.
Solution Approach 2:
The elastic pressing member is pre-configured to apply the necessary tensioning force to the belt through the tension pulley. This preliminary action ensures that the belt is always at the correct tension before operation begins, eliminating the need for frequent post-installation adjustments and reducing maintenance requirements.
3Extent of automation
If an elastic pressure member is used for automatic tension adjustment, then manual intervention is eliminated, but the device complexity increases
Solution Approach 1:
The elastic pressing member is integrated into the existing motor mounting bracket structure, combining the automation function with the structural support function. This merging allows automatic tension adjustment without adding a separate complex tensioning mechanism, thereby maintaining ease of device construction.
Solution Approach 2:
The elastic pressing member acts as an intermediary between the motor mounting bracket and the tension pulley, providing automatic tension adjustment through its elastic properties. This intermediary element simplifies the automation process by using passive elastic force rather than active control mechanisms, avoiding excessive device complexity.
