Engineering Contradiction Analysis
1Productivity
If traditional linear motion actuation methods are used for work-piece transfer, then the system is simple to implement, but the efficiency and productivity are insufficient
Solution Approach 1:
The patent employs dynamic robot arms with multiple degrees of freedom instead of static linear motion mechanisms. The robot arms can adaptively adjust their motion paths and speeds to optimize work-piece transfer efficiency while maintaining system controllability through servo motor control.
Solution Approach 2:
The robot arms are designed to perform multiple functions including transferring work-pieces, positioning them precisely, and coordinating with multiple work stations. This multi-functionality increases productivity while the modular design keeps the overall system complexity manageable.
2Productivity
If walking beam apparatus is used for work-piece transfer, then the apparatus can handle multiple work-pieces, but the maintenance requirements are significant
Solution Approach 1:
The patent replaces traditional mechanical walking beam mechanisms with robot arms driven by servo motors. This substitution eliminates complex mechanical linkages, reducing maintenance requirements while maintaining the capability to handle multiple work-pieces through programmable control.
Solution Approach 2:
The robot arm system incorporates self-diagnostic and self-adjustment capabilities through sensors and control systems, allowing for reduced maintenance intervention. The system can automatically compensate for minor variations and detect potential issues before they require manual repair.
3Manufacturing precision
If multiple robot arms with synchronized control are employed, then precise control and compact design are achieved, but the device complexity increases
Solution Approach 1:
The patent implements feedback control systems with sensors on each robot arm and servo motors that provide real-time position and status information. This feedback enables precise coordinated control of multiple robot arms while the centralized controller manages the complexity through standardized communication protocols.
Solution Approach 2:
The control system is segmented into modular units, with each robot arm having its own servo motor and control interface. This segmentation allows for independent tuning and troubleshooting of each arm while maintaining synchronized operation through the central controller, managing overall system complexity.
