Engineering Contradiction Analysis
1Productivity
If conventional numerical control devices are used without haptic feedback, then the device complexity remains low, but the operator cannot intuitively feel the state of the machine tool, impairing work efficiency
Solution Approach 1:
The patent implements haptic feedback by generating vibrations or resistance forces in the manual handle based on the detected load state of the machine tool. The feedback control unit processes load signals from the load detecting unit and generates corresponding haptic feedback signals that are applied to the manual handle, allowing the operator to intuitively sense the machine tool's state through tactile sensation.
Solution Approach 2:
The manual handle serves as an intermediary device that transmits both operational commands and haptic feedback to the operator. The handle includes a vibration generating unit or resistance mechanism that acts as a mediator between the machine tool's internal state and the operator's tactile perception, enabling intuitive sensing without requiring complex display interfaces.
2Ease of operation
If haptic feedback is added to provide intuitive state sensing, then work efficiency improves, but the device complexity increases
Solution Approach 1:
The feedback control unit receives load signals from the load detecting unit and generates haptic feedback signals that are applied to the manual handle. This closed-loop feedback mechanism allows the operator to intuitively sense the machine tool's state through tactile sensation, improving ease of operation without requiring complex display interfaces or additional control systems.
Solution Approach 2:
The patent replaces visual or auditory monitoring methods with direct mechanical haptic feedback through the manual handle. By using vibration generators or resistance mechanisms integrated into the handle, the system substitutes complex sensing and display systems with a simple tactile interface that provides immediate intuitive feedback to the operator.
