Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple sensors (pressure sensor, force sensor) are used on the robot hand for remote control, then the control precision and feedback accuracy are improved, but the calculation amount becomes enormous and high-performance electronic computers are required
Solution Approach 1:
The patent extracts and removes the complex sensor feedback processing system from the robot control architecture. Instead of using multiple sensors on the robot hand, the invention uses only simple position detection means, eliminating the need for pressure sensors, force sensors, and complex calculation systems while maintaining effective remote control capability through visual feedback from the presentation image.
Solution Approach 2:
The patent creates a visual copy of the robot's operational state through the presentation image that combines camera imagery with model image overlay. This visual representation provides the operator with comprehensive feedback about robot position and status without requiring complex sensor arrays, replacing physical sensor feedback with visual information copying.
2Extent of automation
If multiple sensors and complex control processing are implemented, then the robot can operate autonomously, but the software scale becomes large and development becomes difficult requiring tremendous cost
Solution Approach 1:
The patent enables the operator to directly control the robot through simple action instructions without requiring complex autonomous decision-making software. The system serves the operator's control intentions directly through the presentation image feedback loop, eliminating the need for large-scale autonomous operation software while maintaining effective robot operation.
3Adaptability or versatility
If complex sensor feedback processing is used, then the robot can perform advanced work, but stability and reliability problems remain in autonomous systems
Solution Approach 1:
The patent implements a simplified feedback mechanism through the presentation image that provides the operator with real-time visual information about the robot's position and operational state. This direct visual feedback loop replaces complex sensor feedback processing, improving reliability by eliminating unstable autonomous decision-making while maintaining the ability to perform advanced work through operator control.
