Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If teach pendant or computer software is used for teaching the robotic arm, then the robotic arm can be controlled to perform tasks, but the operation becomes complex and not intuitive
Solution Approach 1:
The patent replaces the mechanical teach pendant with a gesture-based control system that uses camera imaging and computer vision algorithms to recognize hand gestures. This substitution eliminates the need for physical teaching devices while maintaining control functionality, thereby improving ease of operation without significantly increasing device complexity.
Solution Approach 2:
The patent introduces an image processing system as an intermediary between the user's gestures and the robotic arm control. The gesture recognition module captures images, processes them to identify gestures, and translates them into control commands, creating a natural and intuitive interface that simplifies operation while distributing system complexity across multiple modular components.
2Productivity
If teach pendant or computer software is used for teaching the robotic arm, then the robotic arm can be moved and taught positions, but the operation process becomes time-consuming and less efficient
Solution Approach 1:
The gesture recognition system enables continuous real-time control of the robotic arm through ongoing image capture and gesture recognition. Unlike discrete button presses on a teach pendant, the system continuously monitors the user's gestures and provides immediate feedback, eliminating idle time between commands and maintaining continuous productive action throughout the teaching process.
Solution Approach 2:
The system performs preliminary image processing and gesture recognition in real-time before executing robotic arm movements. By pre-processing the gesture data and preparing control commands ahead of time, the system minimizes latency and ensures that the robotic arm responds immediately to recognized gestures, thereby reducing overall teaching time and improving productivity.
3Adaptability or versatility
If multiple separate tools (teach pendant, software) are used for different teaching steps, then comprehensive control is achieved, but the overall system complexity increases
Solution Approach 1:
The gesture recognition system serves multiple functions simultaneously: it captures user gestures, recognizes gesture types, determines gesture positions, generates control commands, and provides visual feedback. This single multi-functional system replaces the teach pendant, control software, and feedback display that previously existed as separate components, thereby maintaining comprehensive control capability while reducing the number of teaching tools required.
Solution Approach 2:
The patent merges the gesture capture, recognition, processing, and feedback functions into an integrated control system. The image processing unit, gesture recognition module, and display unit work together as a unified system, combining previously separate teaching tools into a single cohesive interface that simplifies the overall system architecture while preserving full control versatility.

AI summary
An action teaching method is provided for teaching a robotic arm of a robotic arm system through a gesture teaching device. In a step (a), a touch condition of a user's finger is sensed by the touch sensing unit. In a step (b), a sensing result of the touch sensing unit is transmitted to an identification unit, so that a touch information is identified by the identification unit. In a step (c), the touch information is transmitted to a teaching unit, so that the teaching unit actuates a corresponding operation of the robotic arm system according to the touch information. In a step (d), an operating result of the robotic arm system is shown on a display unit, so that the user judges whether the operating result of the robotic arm system is successful through the display unit.
