Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional robotic arms are programmed with machining processes, then the robot can perform desired treatments on articles, but continuous updates of the machining process are time consuming
Solution Approach 1:
The patent replaces the conventional mechanical programming interface with an optical sensing system. The sensor device detects hand gestures optically and converts them into control signals, eliminating the need for manual programming updates. The control device maps detected gestures to robotic arm movements through a gesture database, enabling direct intuitive control without time-consuming reprogramming.
Solution Approach 2:
The patent introduces a sensor device as an intermediary between the user and the robotic arm. This intermediary captures hand gestures and translates them into actionable commands, serving as a bridge that eliminates the need for direct programming interaction while maintaining precise control over the robotic system.
2Ease of operation
If a handheld remote controller is used to control the robot, then the robot can be operated by user input, but electrostatic interference may occur in controlled environments
Solution Approach 1:
The patent replaces the mechanical contact-based remote controller with a non-contact optical sensing system. The sensor device detects hand gestures through optical fields rather than physical contact, eliminating the transfer of electrostatic charges that occurs with handheld devices while maintaining full operational control of the robotic arm.
3Manufacturing precision
If programming is required for every machining process adjustment, then precise control is achieved, but the system lacks adaptability for instant adjustments
Solution Approach 1:
The patent transforms the static programming system into a dynamic gesture-based control system. The gesture database contains multiple predefined hand gestures that can be instantly activated, allowing the robotic arm to switch between different machining operations dynamically without reprogramming. The system adapts to user needs in real-time through natural hand movements.

Enables efficient and precise control of robotic movements through user-defined gestures, reducing the need for remote controllers and preventing electrostatic interference, thereby enhancing processing efficiency and safety in controlled environments.
Implementation Method 1
The sensor device is mounted to the driven member, and faces toward a sensing zone thereof for sensing, in a non-contact manner, a gesture performed by a user hand in the sensing zone
Data Source
AI summary
A robot includes a moving mechanism, a sensor device and a control device. The sensor device senses a gesture of a user hand in a sensing zone thereof. The control device causes the moving mechanism to perform an action instruction that corresponds to the gesture when the gesture matches a piece of gesture data in a gesture database thereof.
