Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional robot control systems are used for object grasping and positioning, then the system structure is simple, but the grasping precision and positioning accuracy are insufficient
Solution Approach 1:
The patent implements feedback mechanisms through sensors (proximity sensors, force sensors) that continuously monitor the robotic arm's position and the object's state during grasping. The control system processes this feedback information and adjusts the robotic arm's movements in real-time to achieve precise grasping and positioning, directly resolving the precision-accuracy tradeoff
Solution Approach 2:
The patent replaces traditional mechanical positioning systems with sensor-based detection and control systems. Instead of relying solely on mechanical precision, the system uses electronic sensors to detect position and control units to calculate and adjust movements, achieving higher precision without proportionally increasing mechanical complexity
2Productivity
If coordinate system creation is simplified for faster operation, then the operation speed increases, but the alignment accuracy between robotic arm and object decreases
Solution Approach 1:
The patent establishes a coordinate system in advance based on the platform before the grasping operation begins. This preliminary coordinate system creation allows the control system to quickly reference pre-calculated positions and transformations during operation, maintaining high speed while ensuring accurate alignment through the pre-established spatial relationships
Solution Approach 2:
The system continuously monitors the actual position of the robotic arm and object during operation, comparing it against the pre-established coordinate system. Real-time feedback allows the system to make minor adjustments to maintain alignment accuracy while operating at high speed, reconciling the trade-off between speed and precision

AI summary
A robot control system on a platform which can carry target objects employs a coordinate system including X, Y, and Z axes. A plane including the X and Y axis is parallel with a panel including the platform. After the coordinate system is created, a reminder is displayed and a guiding tool is placed in a position on the platform where the target objects are located, and a fastening tool for use with the guiding tool is arranged on hand of the robot. A location of the fastening tool relative to the guiding tool is adjusted according to a predefined rule. When the location of the fastening tool relative to the guiding tool is correctly adjusted, a position of the end effect of the robot is determined according to the location of the fastening tool and the relevant coordinates are stored as data.
