Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional shot peening apparatus with clamping means and conveyer is used, then coil spring can be held and moved, but apparatus complexity increases and workspace expands
Solution Approach 1:
The invention extracts and eliminates the clamping means and conveyer components from the conventional shot peening apparatus. Instead of using separate clamping and conveying mechanisms, the coil spring is directly mounted on the rotating and revolving mounting unit, which performs both positioning and movement functions through its rotational and revolute motions alone.
Solution Approach 2:
The mounting unit is designed to perform multiple functions simultaneously: it holds the coil spring, rotates it for uniform shot peening, revolves it for continuous processing, and positions it for optimal shot impact. This multi-functional design replaces the need for separate clamping means and conveyer apparatus, thereby reducing overall device complexity while maintaining ease of operation.
2Ease of operation
If conventional conveyer apparatus is used to move coil spring, then coil spring can be transported, but processing time increases and productivity decreases
Solution Approach 1:
The invention transitions from static conveyer-based transport to dynamic rotational and revolute motion. The mounting unit continuously rotates and revolves during the shot peening process, enabling the coil spring to be processed in a dynamic state rather than being passively transported and then processed. This dynamic approach allows for continuous shot peening operation without interruption.
Solution Approach 2:
The mounting unit enables continuous shot peening operation by maintaining constant rotational and revolute motion throughout the processing cycle. Unlike conventional conveyer systems that require discrete loading, unloading, and processing steps, the continuous motion of the mounting unit allows the shot peening process to proceed without interruption, significantly improving productivity and reducing total processing time.
3Device complexity
If coil spring is stationary during shot peening, then processing is simple, but shot peening uniformity deteriorates
Solution Approach 1:
The invention applies dynamic rotation and revolution to the coil spring mounting unit during shot peening. The rotational motion ensures uniform distribution of shot impacts around the coil spring circumference, while the revolute motion provides continuous exposure to shot particles from multiple directions. This dynamic approach achieves highly uniform shot peening results without requiring overly complex processing mechanisms.
