Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The operability of the master controller in robotic surgical systems is compromised due to automatic adjustments based on the viewer angle, leading to potential inefficiencies in operator control.
Innovation Solution
A robotic surgical system with an operation unit having a coordinate system that can be rotated by a predetermined angle, allowing operators to adjust the system to their preference, and a control method that receives and implements these changes to enhance usability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the coordinate system of the master controller is automatically adjusted according to the angle of the viewer, then the system maintains automatic coordination between viewer angle and controller orientation, but the operability of the master controller deteriorates depending on the operator's preferences
Solution Approach 1:
The system dynamically switches between automatic coordinate system adjustment mode and manual adjustment mode. The operation unit can be rotated by a predetermined angle based on operator preference, and the system adapts by receiving this rotational input and adjusting the coordinate system accordingly, rather than forcing automatic adjustment only based on viewer angle
Solution Approach 2:
The system changes the parameter of coordinate system orientation by receiving a predetermined rotation angle from the operator. This allows the operator to modify the coordinate system parameters to match their operational preferences, improving ease of operation while maintaining system functionality
2Device complexity
If the coordinate system is fixed according to viewer angle, then the system structure remains simple and automatic, but the ease of operation deteriorates due to lack of operator customization
Solution Approach 1:
The system transitions from a static, purely automatic coordinate system adjustment mechanism to a dynamic system that can switch between automatic adjustment based on viewer angle and manual adjustment based on operator input. The operation unit's rotatability by a predetermined angle introduces dynamic adaptability without significantly complicating the overall system structure
Solution Approach 2:
The operator is empowered to self-adjust the coordinate system orientation by rotating the operation unit according to their preferences. This self-service capability allows operators to customize the system to their needs without requiring complex configuration procedures or additional system complexity
