Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual replacement of polishing discs is used, then careful handling is possible, but the replacement process is time-consuming
Solution Approach 1:
The system performs self-service through automated detection and replacement. Sensors automatically detect when polishing discs need replacement, and the system executes the replacement process without manual intervention, thus eliminating the time-consuming nature of manual replacement while maintaining proper handling through automated control mechanisms.
Solution Approach 2:
The patent replaces manual mechanical operations with an automated system. The replacement process that previously required careful manual handling is now performed by an automated mechanism controlled by sensors and a control unit, substituting human mechanical actions with automated mechanical and electronic control.
2Loss of time
If automated replacement system is implemented, then replacement time is reduced, but device complexity increases
Solution Approach 1:
The automated replacement system is integrated into the existing polishing machine structure, serving multiple functions: detection of disc wear, positioning of replacement discs, execution of replacement, and monitoring of the process. This multi-functionality reduces the need for separate dedicated components, thereby limiting the increase in device complexity.
Solution Approach 2:
The patent merges the replacement function with the existing polishing machine structure. The support plate with stacking devices and the automated replacement mechanism are integrated into the machine's frame, combining multiple functions into a unified system rather than adding separate independent systems.
3Ease of operation
If polishing disc extends beyond backing plate, then removal is easier, but positioning precision is reduced
Solution Approach 1:
The patent introduces positioning elements as intermediaries between the polishing disc and the backing plate. These elements facilitate easy removal while maintaining precise positioning during operation, mediating between the conflicting requirements of removal ease and positioning precision.
Solution Approach 2:
The polishing disc has different properties in different regions: the working surface maintains precise positioning for polishing operations, while the edge extending beyond the backing plate provides ease of removal. This local differentiation of properties resolves the contradiction between positioning precision and removal ease.
