Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If programming is used to control moving speed and discharge amount in a linked manner, then desired line drawing application can be achieved, but programming workload and time increase significantly
Solution Approach 1:
The system enables self-service by allowing the discharge amount control to automatically adjust based on real-time moving speed feedback without requiring external programming intervention. The control unit autonomously processes the relationship between speed and discharge amount, eliminating the need for manual programming while maintaining precise line drawing application.
Solution Approach 2:
The invention implements feedback control by continuously monitoring the moving speed of the discharge head and automatically adjusting the discharge amount based on this information. The control unit receives speed data and dynamically modifies discharge parameters to maintain uniform line application, resolving the contradiction between precision and programming complexity.
2Ease of operation
If separate control units are used for movement and discharge control, then programming workload is reduced, but system complexity increases
Solution Approach 1:
The invention merges the control functions by integrating the discharge amount control unit with the movement control system. The control unit that manages movement also processes speed information and automatically adjusts discharge amounts, combining multiple functions into a single integrated controller. This reduces operational complexity while maintaining the benefits of automated control.
3Manufacturing precision
If discharge amount is manually adjusted at different positions, then application precision can be improved, but operation complexity and error potential increase
Solution Approach 1:
The system performs self-service by automatically adjusting discharge amounts based on real-time speed feedback without requiring manual intervention. The control unit autonomously determines the appropriate discharge amount at each position based on the current moving speed, eliminating manual adjustment operations while maintaining high application precision.
Solution Approach 2:
The invention uses feedback control where the control unit continuously monitors moving speed and automatically adjusts discharge amount in real-time. This closed-loop control system eliminates manual adjustment operations while maintaining precise application, as the system self-corrects based on actual speed conditions.
