Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a large number of servo driving units are used to control each motor independently, then the transport line can achieve precise control and high flexibility, but the system complexity and wiring complexity increase significantly
Solution Approach 1:
The patent merges multiple servo driving units into a single centralized driving unit that can control multiple motors sequentially. Instead of having independent servo drivers for each motor, one driving unit with multi-axis control capability manages all motors, reducing the number of driving units and simplifying the overall system architecture while maintaining control flexibility
Solution Approach 2:
The centralized driving unit is designed with universal control capability to manage multiple motors through multi-axis control. This single unit performs the functions previously distributed across multiple specialized servo drivers, reducing component count while preserving the ability to control each motor independently when needed
2Speed
If high-performance DSPs or FPGAs are used for real-time calculation and communication in each driving unit, then the system response speed and precision are improved, but the system cost increases significantly
Solution Approach 1:
The patent consolidates the computing resources previously distributed across multiple high-performance DSPs or FPGAs into a single centralized driving unit. This unified computing platform handles all real-time calculations and communication tasks, reducing the total quantity of expensive high-performance processors while maintaining system response speed through centralized optimization
3Productivity
If multiple independent servo driving units are deployed for each motor, then real-time control of each motor is achieved, but the wiring complexity and system cost increase
Solution Approach 1:
The patent merges multiple independent servo driving units into one centralized multi-axis driving unit. This consolidation reduces the number of separate driving components and their associated wiring connections, simplifying the overall wiring architecture while maintaining the ability to control each motor in real-time through the unified control platform
