Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If a motor is used to rotate the turntable assembly, then rotational speed can be controlled, but inconsistent speeds occur due to varying torque requirements for different load weights
Solution Approach 1:
The patent incorporates a feedback mechanism where a sensor detects the actual rotational speed of the turntable assembly and feeds this information back to the control circuit. The control circuit then adjusts the motor's power output to compensate for variations in torque requirements, ensuring consistent rotational speed across different load weights. This closed-loop control system directly addresses the reliability issue by continuously monitoring and correcting speed fluctuations.
2Ease of operation
If multiple switches, pedals and knobs are used to control rotational direction and speed, then precise control is achieved, but operational complexity and inconvenience increase
Solution Approach 1:
The patent merges the control functions for rotational direction and speed adjustment into a single integrated control interface. Instead of requiring separate switches, pedals, and knobs, the user interacts with one unified control mechanism that simultaneously adjusts both parameters. This consolidation reduces operational complexity while maintaining precise control capabilities, as the control circuit processes combined input signals to coordinate motor operation.
3Adaptability or versatility
If manual operation or basic electric systems are used, then device complexity is reduced, but control precision and mobility are limited
Solution Approach 1:
The patent replaces manual mechanical operation with an electrically powered motor system that provides superior control precision and mobility. The motor, controlled by an electronic control circuit, offers adjustable speed and direction with greater precision than manual systems. The electric power system enables wireless or cordless operation, enhancing mobility and flexibility while the integrated control circuit manages complexity to maintain ease of use.
