Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If each grinding element has its own motor drive, then the rotational speed of grinding elements can be independently controlled, but the cost and complexity of drive motors increases significantly
Solution Approach 1:
Multiple grinding elements are merged into a single group that shares a common drive motor. The flexible friction-locking or form-fitting arrangement allows one motor to drive multiple grinding elements simultaneously, reducing the total number of motors while maintaining synchronized rotation speeds for all elements in the group.
Solution Approach 2:
A single drive motor is designed to serve multiple grinding elements through the flexible drive arrangement. This universal drive system can rotate any number of grinding elements at the same speed, making the motor multi-functional and eliminating the need for individual motors for each grinding element.
2Device complexity
If the grinding elements are driven by the transport device, then the structure is simplified, but the rotational speed of grinding elements becomes dependent on transport speed
Solution Approach 1:
The drive system is segmented into two independent functions: the transport device moves the grinding heads along the workpiece, while the separate flexible friction-locking or form-fitting arrangement driven by a dedicated motor provides rotational drive to the grinding elements. This segmentation allows independent control of transport speed and grinding element rotational speed.
Solution Approach 2:
A flexible friction-locking or form-fitting arrangement acts as an intermediary between the drive motor and the grinding elements. This intermediary mechanism transmits rotational motion from the motor to the grinding elements while allowing the transport device to operate independently, thus decoupling the rotational speed from the transport speed.
3Manufacturing precision
If multiple drive motors are used for each grinding element, then the grinding parameters can be precisely controlled, but the cost of drive motors increases
Solution Approach 1:
The patent merges multiple individual drive motors into a single common drive motor that serves multiple grinding elements. By combining the drive functions, the total quantity of motors is reduced while the grinding precision is maintained through the synchronized rotation of all grinding elements at the same speed.
