Innovation Solution
A mobile medical imaging robot with manual motorized moving, equipped with security sensors and a human machine interface like a joystick for user control, and a permanently fixed cable for power and data transmission, allowing for simpler and cost-effective operation with enhanced security features.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the mobile medical imaging robot is fully automated, then security of robot moving control is improved, but device complexity and cost increase
Solution Approach 1:
The control system is segmented into two parts: basic automated navigation for routine movements (parking, positioning) and manual control for exceptional situations. This segmentation allows the system to maintain high security through automated protocols while avoiding the complexity of fully automated control by allowing manual intervention when needed.
Solution Approach 2:
The robot performs routine movements autonomously without human intervention, such as returning to parking positions or moving between predetermined examination locations. This self-service capability maintains security while reducing operational complexity for common tasks.
2Device complexity
If the mobile medical imaging robot is fully manual, then device complexity and cost are reduced, but security of robot moving control deteriorates
Solution Approach 1:
The control mode is made dynamic, allowing the system to switch between automated and manual control based on operational needs. The robot operates in automated mode for routine tasks to ensure security, and can be switched to manual mode when flexibility is required, providing adaptability without compromising overall security.
3Use of energy by moving object
If the mobile medical imaging robot is cable linked to wall, then power and data transfer are improved, but moving magnitude is limited and cable damage risk increases
Solution Approach 1:
The cable management system uses preliminary action by implementing predetermined travel paths and parking positions. The robot is programmed to move only along predefined trajectories that keep the cable within safe tension limits, preventing cable damage while maximizing the usable moving magnitude within constraints.
Solution Approach 2:
The system incorporates feedback mechanisms through sensors that monitor cable tension and position. When the robot approaches movement limits that would endanger the cable, the system receives feedback and automatically adjusts or stops movement, preventing cable damage while optimizing power and data transfer capabilities.
4Use of energy by moving object
If the mobile medical imaging robot is cable linked to wall, then power and data transfer are improved, but device complexity increases due to automatic control requirements
Solution Approach 1:
The control system is segmented into two parts: basic automated navigation for routine movements (parking, positioning) and manual control for exceptional situations. This segmentation allows the system to maintain high security through automated protocols while avoiding the complexity of fully automated control by allowing manual intervention when needed.
