Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If data transfer and communication with external networks are restricted to maintain security in wafer processing facilities, then system security is improved, but troubleshooting capability and error identification speed deteriorate
Solution Approach 1:
The patent creates a virtual copy of the robot system including 3D models of robot components, motor positions, and operation logs that replicate the physical system's state. This virtual model allows operators to analyze errors and troubleshoot without requiring external network communication, thus maintaining security while enabling effective debugging through the copied system representation
Solution Approach 2:
The video confirmation computer serves as an intermediary device that receives data from the robot controller and presents it in a comprehensible format to operators. This intermediary allows the isolated robot system to communicate its operational state and error conditions to human operators without requiring direct external network access, bridging the gap between security restrictions and troubleshooting needs
2Device complexity
If operators rely on traditional separate monitoring methods for robot operations, then system complexity is reduced, but error identification speed and understanding accuracy deteriorate
Solution Approach 1:
The patent merges multiple separate monitoring functions into a single integrated display interface that simultaneously shows video footage, 3D robot models, motor position data, and operation logs. This consolidation allows operators to access all relevant information in one view rather than switching between multiple systems, reducing the time needed to identify and understand errors despite increasing the information density in the monitoring system
3Device complexity
If detailed robot operation data is displayed separately in different formats, then information organization is simplified, but operator understanding and situation grasp deteriorate
Solution Approach 1:
The patent transforms traditional two-dimensional video and text data into a three-dimensional visual representation by displaying robot component positions and movements in a 3D model that matches the physical robot's spatial configuration. This dimensional transformation allows operators to intuitively understand robot posture and movement in space, significantly improving comprehension while the system organizes detailed operational data across multiple visual dimensions
Data Source
AI summary
A video confirmation computer for confirming video related to robot operation includes a storage unit and a processor. The storage unit stores information on the position of the electric motor that drives a link body of the robot received from the controller of the robot and information on the video obtained by a camera attached to the robot. The processor makes at least one of the video confirmation computer itself and a computer connected to the video confirmation computer display a model area and a video area side by side. In the model area, a two-dimensional or three-dimensional model reproducing the posture of the robot is displayed by computer graphics. In the video area, the video is displayed.
