Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If operation state data is acquired from a fixed movement machine, then the control system is simple, but the adaptability to switch between multiple movement machines is limited
Solution Approach 1:
The patent implements dynamic switching between movement machines by introducing a movement machine switching section that can change the target movement machine based on work content. The control device transitions from a static data acquisition system to a dynamic one where the movement machine to be monitored can be changed according to the work program, enabling adaptability while managing complexity through structured control flows.
Solution Approach 2:
The control device is designed to handle multiple movement machines universally. The movement machine operation section, operation state data acquisition section, and adaptive control execution section can operate with any movement machine in the system. The switching mechanism allows a single control device to adaptively manage different movement machines for different work contents, achieving multi-functionality.
2Adaptability or versatility
If adaptive control is implemented with multiple movement machines, then the flexibility of end effector operations is improved, but the complexity of managing operation state data increases
Solution Approach 1:
The patent employs feedback mechanisms where operation state data from the movement machine is continuously acquired and fed back to the adaptive control execution section. This feedback loop enables the system to adjust end effector output values based on actual movement machine operation states, achieving flexible adaptive control while managing data complexity through structured feedback processing.
Solution Approach 2:
The control device performs preliminary actions by pre-defining work contents and associated movement machines in the work program. Before actual operation, the system prepares the control flow by determining which movement machine will be used for each work content, reducing the complexity of data management during execution through advance planning.
3Productivity
If dynamic switching between movement machines is enabled, then the efficiency of workpiece processing is improved, but the difficulty of detecting and measuring operation states increases
Solution Approach 1:
The patent introduces an intermediary data acquisition mechanism where the movement machine operation section acts as a mediator between the movement machine and the control device. This intermediary section standardizedly acquires operation state data regardless of which movement machine is active, simplifying the detection and measurement process while enabling efficient switching between machines for improved workpiece processing.
