Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a multipurpose robot arm uses a single control mode with fixed operation values, then the control system is simple and easy to program, but the robot cannot achieve high precision and accuracy for different tools and applications
Solution Approach 1:
The robot controller dynamically switches between standard mode and application-specific mode based on the operational requirements. In standard mode, fixed operation values are used for general tasks, while in application-specific mode, tool-dependent operation values are applied for precision tasks. This dynamic adaptation allows the system to optimize precision without permanently increasing complexity.
Solution Approach 2:
The system changes operational parameters (operation values) based on the mode of operation. Different operation values are stored and selected according to the specific tool and application requirements. This parameter variation enables the robot to achieve high precision for specific applications while maintaining simplicity for general operations.
2Manufacturing precision
If a multipurpose robot arm is programmed for high precision operations, then accuracy improves, but programming complexity and difficulty increase significantly
Solution Approach 1:
The control system is segmented into two distinct modes: standard mode for general operations and application-specific mode for precision tasks. Each mode has its own set of operation values and control parameters. This segmentation allows users to program simple standard operations without dealing with complex precision parameters, while high-precision applications can utilize dedicated application-specific parameters.
Solution Approach 2:
The robot controller is designed to be universal by supporting both standard and application-specific modes within a single system. The same hardware platform can handle both simple and complex tasks by switching modes, eliminating the need for separate programming approaches for different precision levels and simplifying the overall operational interface.
3Reliability
If different specialized robots are used for different tools and applications, then each robot can be optimized for its specific function, but the system requires multiple robots increasing cost and complexity
Solution Approach 1:
A single multipurpose robot arm is equipped with the capability to handle multiple different tools and applications by switching between standard mode and application-specific mode. The controller stores operation values for various tools and applications, allowing one robot to perform the functions of multiple specialized robots, thereby maintaining versatility while reducing system complexity and cost.
Solution Approach 2:
The robot system achieves tool-specific optimization through parameter changes rather than hardware changes. Different operation values corresponding to different tools and applications are stored in the controller, and the appropriate parameters are selected based on the current tool and task. This allows a single robot to be optimized for different functions by simply changing operational parameters.
