Medical System Bendable Unit Controller
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face challenges in determining whether a replacement component for a medical device's bendable unit is usable and requires precise control, due to variations in structure and characteristics, leading to increased burden in adapting settings and ensuring optimal operation.
Innovation Solution
A medical system with a base unit and a bendable unit that includes a controller, which uses stored information to automatically control the drive portion based on the bendable unit's historical use, region number, length, and response characteristics, ensuring optimal operation and preventing misuse of used components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the user manually determines whether a replacement component is usable and adjusts settings to adapt to new components, then the user can ensure proper operation, but the user burden increases significantly
Solution Approach 1:
The replacement component autonomously transmits its identification information and usage history to the base unit's storage unit. The control unit automatically determines usability and configures optimal control parameters based on stored information, eliminating the need for manual user assessment and settings adjustment.
Solution Approach 2:
The system implements automatic feedback loops where the control unit continuously monitors component status, retrieves usage history from storage, and dynamically adjusts control parameters to optimize performance. This closed-loop control ensures reliable operation without requiring user intervention.
2Reliability
If the user manually adjusts control settings for each new replacement component, then optimal control can be achieved, but time is lost in the adjustment process
Solution Approach 1:
The system pre-stores optimal control parameters and usage history in the storage unit during manufacturing or previous operations. When a replacement component is installed, the control unit automatically retrieves and applies the pre-configured parameters, eliminating the time-consuming manual adjustment process while maintaining optimal control precision.
3Adaptability or versatility
If the system allows operation of used bendable units, then component availability increases, but safety and hygiene may be compromised
Solution Approach 1:
The storage unit stores usage history information indicating whether a bendable unit has been previously used. The control unit proactively prevents operation of used components by checking this stored information before allowing operation, thereby preemptively blocking potential contamination risks while maintaining system availability through proper component replacement protocols.

AI summary
A medical system includes: a base unit; a bendable unit that is attachable to and detachable from the base unit and that includes a linear member that is driven by the drive portion in a state in which the bendable unit is attached to the base unit and a bending portion that bends as the linear member is driven; and a controller that controls the drive portion. The bendable unit includes a first information storage that stores first information specific to the bendable unit. The first information includes historical information indicating whether the bendable unit has not been used or has been used. If the historical information indicates that the bendable unit has not been used, the controller permits operation of the drive portion, and, if the historical information indicates that the bendable unit has been used, the controller does not permit operation of the drive portion.
