Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual cutting method is used to remove burrs, then labor intensity is reduced, but machining efficiency decreases and wheel surface is damaged
Solution Approach 1:
The patent replaces the manual mechanical cutting system with an automated laser cutting system. The laser beam melts and vaporizes the burrs through thermal energy, eliminating the need for manual mechanical cutting tools and operators, thereby reducing labor intensity while significantly improving machining efficiency and avoiding surface damage.
Solution Approach 2:
The patent changes the cutting mechanism from mechanical contact to thermal processing. By using laser energy to heat and melt the burr material, the process parameters (temperature, energy density) are controlled to achieve clean cutting without mechanical force, thus improving efficiency and preserving wheel surface integrity.
2Ease of operation
If manual cutting method is used to remove burrs, then labor intensity is reduced, but wheel surface quality deteriorates
Solution Approach 1:
The patent replaces manual mechanical cutting with laser-based thermal cutting. The laser beam precisely melts and removes burrs without mechanical contact, eliminating surface scratching and damage caused by manual tools, thereby maintaining high wheel surface quality while reducing labor intensity.
Solution Approach 2:
The laser cutting process creates a precise digital control path that accurately follows the wheel contour, ensuring consistent and high-quality burr removal across all wheels. This automated path replication maintains surface quality better than manual methods while reducing labor intensity.
3Productivity
If automated laser cutting is implemented, then machining efficiency improves, but device complexity increases
Solution Approach 1:
The laser cutting device is designed to handle multiple wheel types and sizes using the same core laser mechanism. By programmatically adjusting cutting paths and parameters, the system achieves high machining efficiency across different applications without requiring multiple specialized devices, thus managing complexity while improving productivity.
4Manufacturing precision
If automated laser cutting is implemented, then machining precision improves, but manufacturing cost increases
Solution Approach 1:
The patent replaces manual mechanical cutting with automated laser cutting, which provides superior machining precision through controlled thermal processing. Although the initial equipment cost is higher, the elimination of manual labor, reduced material waste, and improved surface quality (reducing rejection rates) result in lower overall manufacturing costs.
