Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a motor is added to control the potentiometer slider remotely, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The patent replaces manual mechanical adjustment of the potentiometer with an automated motor-driven system. The motor responds to electrical signals from the remote control to automatically position the potentiometer slider, eliminating the need for physical contact with the welding machine and enabling remote operation.
Solution Approach 2:
The patent introduces a motor as an intermediary device between the remote control and the potentiometer. The motor receives electrical commands from the remote control and translates them into mechanical motion to adjust the potentiometer slider position, serving as a mediator that bridges the remote operator and the control mechanism.
2Productivity
If wireless remote control is implemented, then the productivity is improved, but the reliability may worsen due to potential signal interference
Solution Approach 1:
The patent implements a dynamic control system where the motor can respond to varying remote control signals during welding operations. The system allows real-time adjustment of welding parameters through wireless communication, enabling the operator to dynamically adapt welding conditions without interrupting the welding process.
