Medical Robot Dynamic Working Range Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Medical robots are often designed with conservative performance specifications to meet the 'worst case' requirements, leading to inefficient use of resources and performance, particularly in medical applications where varying demands exist for working range, rigidity, payload, speed, and acceleration.
Innovation Solution
A method and system for dynamically adjusting the working range of a medical robot using a control device, specifically through secure technology, to match the performance requirements of the attached medical tool, including limiting travel distance, Cartesian workspace, and zero space, thereby optimizing performance for specific applications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the robot is designed to meet the 'worst case' configuration requirements, then the reliability and safety are improved, but the performance specifications become overly conservative and resource utilization deteriorates
Solution Approach 1:
The patent applies dynamics by making the working range adjustable rather than fixed. The control device dynamically modifies the robot's working range based on the specific medical tool attached and the required application, allowing the system to adapt between conservative safety configurations and optimized performance configurations, thereby resolving the contradiction between reliability and productivity
Solution Approach 2:
The patent changes the parameter of working range from a static design constraint to a dynamic control variable. By modifying the working range parameters based on tool-specific requirements and application demands, the system achieves both safety (through appropriate limitations) and optimal resource utilization (by not being overly conservative when not needed)
2Manufacturing precision
If the working range is limited to satisfy specific application requirements, then the manufacturing precision and performance are improved, but the adaptability to different applications deteriorates
Solution Approach 1:
The control device enables dynamic adjustment of the working range based on the attached medical tool and application requirements. This dynamic approach allows the robot to achieve precise performance for each specific application while maintaining the ability to adapt to different tools and procedures, resolving the contradiction between manufacturing precision and adaptability
Solution Approach 2:
The system incorporates feedback mechanisms where the control device receives information about the attached tool and application requirements, then adjusts the working range accordingly. This feedback loop ensures that the robot operates with optimal precision for each specific task while maintaining versatility across different medical applications
