Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If polishing components are used without a positioning assembly, then the polishing process can be simpler, but the polishing components will shift leading to reduced service life and inconsistent polishing quality
Solution Approach 1:
The positioning assembly is segmented into multiple functional components including positioning plates, positioning grooves, and clamping mechanisms. This segmentation allows each component to perform its specific function while collectively ensuring the polishing plate remains firmly positioned without requiring an overly complex integrated structure.
Solution Approach 2:
The positioning assembly utilizes the workpiece itself and the polishing plate geometry to achieve positioning. The positioning grooves and plates work with the existing components to maintain alignment, reducing the need for additional complex external positioning devices.
2Duration of action of stationary object
If the polishing plate is not firmly positioned, then the apparatus structure can be simpler, but the polishing plate will shift causing reduced service life
Solution Approach 1:
The positioning assembly is configured to establish the correct position of the polishing plate before the polishing operation begins. The positioning grooves and clamping mechanisms pre-establish firm positioning, preventing any shifting during the polishing process and thereby extending the service life of the polishing plate.
Solution Approach 2:
The positioning plates and positioning grooves act as intermediary elements between the bracket and the polishing plate. These intermediaries transmit and maintain the positional relationship, ensuring the polishing plate remains firmly positioned without requiring direct complex connections.
3Manufacturing precision
If a positioning assembly is added to prevent shifting, then polishing quality consistency improves, but the apparatus becomes more complex
Solution Approach 1:
The positioning assembly focuses its functionality at specific critical locations where the polishing plate contacts the bracket. Rather than providing uniform positioning throughout the entire apparatus, the positioning plates and grooves are strategically placed at key interfaces to ensure alignment and prevent shifting, achieving precision without unnecessary complexity.

AI summary
A polishing apparatus connected to a robot arm and used to polish a workpiece includes a bracket, a polishing assembly, and a positioning assembly. The polishing assembly is mounted on the bracket and includes a driver and a polishing plate connected to the driver. The driver is capable of driving the polishing plate to rotate, and defines an annular positioning groove around the spin axis. The positioning assembly includes a first positioning plate and a second positioning plate mounted on the bracket and opposite to the first positioning plate. The first positioning plate and the second positioning plate are clamped into two sides of the positioning groove, whereby the driver is clamped between the first positioning plate and the second positioning plate.
