Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a robot performs multiple tasks including transferring objects between conveyors and placing them in boxes, then productivity is improved, but the complexity of the robot system increases due to requiring multiple end effectors and tool changers
Solution Approach 1:
A single robotic end effector is designed to perform multiple functions: transferring objects between conveyors and placing objects in boxes. The end effector can switch between different gripper types (first gripper for conveyor transfer, second gripper for box placement) without requiring tool changers, making the robot system universal and multi-functional.
Solution Approach 2:
Multiple gripper functions are merged into a single end effector assembly. The first gripper and second gripper are integrated on the same robotic manipulator, allowing the robot to perform both conveyor-to-conveyor transfer and conveyor-to-box placement operations with one tool, eliminating the need for separate end effectors and tool changers.
2Adaptability or versatility
If tool changers are used to enable robots to perform multiple tasks, then adaptability is improved, but the time required for task switching increases
Solution Approach 1:
Multiple gripper types are combined into a single end effector, eliminating the need for tool changers. The robotic manipulator can switch between the first gripper and second gripper instantaneously by actuating different gripping mechanisms on the same tool, avoiding the time-consuming tool changeover process while maintaining high adaptability for different tasks.
Solution Approach 2:
The end effector is designed with dynamic switching capability between different gripper configurations. The robotic manipulator can rapidly transition between gripping modes (first gripper for transfer, second gripper for placement) through dynamic actuation, enabling fast task switching without physical tool changes.
3Manufacturing precision
If separate end effectors are used for different tasks, then manufacturing precision is maintained for each task, but device complexity increases
Solution Approach 1:
A single end effector is designed with multi-functional capability to maintain manufacturing precision for different tasks. The end effector incorporates both the first gripper (optimized for conveyor transfer precision) and the second gripper (optimized for box placement precision), allowing one tool to achieve task-specific precision requirements without requiring multiple specialized end effectors.
Solution Approach 2:
Different gripping mechanisms within the same end effector are optimized for their specific functions: the first gripper is designed with local quality features for precise conveyor-to-conveyor transfer, while the second gripper has different local quality features for precise conveyor-to-box placement. This allows each function to maintain its precision requirements while being part of a unified end effector system.
