Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If welding is performed by a robot using conventional methods, then welding automation is achieved, but laborious preparation for manual welding or extensive teaching is required
Solution Approach 1:
The welding robot allows the worker to perform welding operations directly by manually moving the robot arm and operating the trigger switch, eliminating the need for extensive teaching or preparation. The system serves itself by accepting direct human operation without requiring complex programming or setup procedures.
Solution Approach 2:
The robot system combines both automated welding capability and manual operability into a single device. The welding torch portion can function both as an automated welding tool and as a manually controlled welding tool, allowing the same equipment to serve multiple purposes without requiring separate systems.
2Ease of operation
If the welding torch portion is made movable by external force for easy operation, then ease of operation is improved, but control over welding execution may be compromised
Solution Approach 1:
The welding robot incorporates a dynamic control system that responds to the worker's operations in real-time. The servo mechanism dynamically adjusts the robot arm's movement based on external forces applied by the worker, while the trigger switch dynamically controls the welding current. This dynamic responsiveness ensures both ease of operation and reliable control over welding execution.
Solution Approach 2:
The system provides feedback through the servo mechanism that responds to external forces applied to move the robot arm. The control unit receives signals from the trigger switch and adjusts the welding current accordingly, creating a feedback loop that ensures reliable control while maintaining ease of operation. The worker can feel the resistance and response of the system, providing tactile feedback for precise control.
