Surgical Manipulator Switch Customization for Flexible Robot Arm Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing robotic surgical systems lack the flexibility for operators to freely customize the functions performed by switches on the operation unit, limiting the degree of freedom in operation.
Innovation Solution
Incorporation of a customized switch in the operation unit that allows operators to set desired functions through function setting, enabling flexibility in switch operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a predetermined switch function is used in the operation unit, then the system structure remains simple and reliable, but the degree of freedom in switch functions is limited
Solution Approach 1:
The switch function is made dynamic and changeable rather than fixed. The controller changes the switch function based on the operational state of the robotic surgical system, allowing the same physical switch to perform different functions at different times. This resolves the contradiction by providing adaptability through temporal dynamics while maintaining simple hardware structure.
Solution Approach 2:
The functional parameter of the switch is changed based on system state rather than changing the physical switch itself. The controller monitors operational parameters and dynamically reassigns switch functions according to the current operational context, enabling versatility without adding physical complexity to the operation unit.
2Adaptability or versatility
If multiple fixed-function switches are provided, then operational versatility is achieved, but the operation unit becomes more complex
Solution Approach 1:
A single physical switch is designed to perform multiple functions depending on the system state. The controller dynamically assigns different functions to the same switch based on operational context, allowing one switch to replace multiple specialized switches. This maintains operational versatility while simplifying the physical operation unit structure.
Solution Approach 2:
The switch function is made dynamic rather than static. The same physical switch adapts its function based on real-time system state, providing operational versatility without requiring multiple fixed-function switches. This dynamic reassignment simplifies the operation unit while maintaining comprehensive functionality.
