Manipulator System Sensor Verification for Connection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional manipulator systems for medical devices lack effective methods to confirm normal operation and connection between the manipulator and driving device, leading to potential malfunctions and errors.
Innovation Solution
A manipulator system with a control device that uses a first sensor to confirm the driving device's normal operation and a second sensor to verify the manipulator's connection, reducing the need for duplicate sensors by utilizing the outputs of both sensors to check for abnormalities in the manipulator and driving device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If sensors are duplicated to ensure normal operation, then reliability is improved, but device complexity increases
Solution Approach 1:
The patent applies multi-functionality by enabling the first sensor to serve dual purposes: confirming the driving device operates normally and detecting abnormalities in the manipulator through its output. This allows a single sensor to perform functions that would traditionally require multiple sensors, thereby maintaining reliability while reducing device complexity
Solution Approach 2:
The patent implements feedback mechanisms where the control device continuously monitors the output of the first sensor to confirm normal operation and uses this feedback to detect abnormalities. The system feeds back sensor data to the control device, which then determines whether the manipulator is abnormally connected, enabling reliable operation confirmation without duplicating sensors
2Measurement precision
If multiple sensors are used to check connection and operation, then measurement precision is improved, but quantity of sensors increases
Solution Approach 1:
The first sensor is designed to perform multiple measurement functions: it confirms the driving device operates normally and simultaneously detects abnormalities in the manipulator connection. This multi-functional approach maintains measurement precision for connection confirmation while reducing the total quantity of sensors needed in the system

AI summary
A manipulator system includes: a manipulator; a driving device to which the manipulator is detachably connected and which electrically drives the manipulator; a control device; a first sensor provided in the driving device; and a second sensor provided in the manipulator or the driving device. The control device is configured to perform a first step of confirming that the driving device operates normally according to electric power on the basis of an output of the first sensor, and a second step of confirming that the manipulator is connected to the driving device on the basis of an output of the second sensor. The first step includes checking whether the first sensor is normal, and the second step includes checking whether the second sensor is normal on the basis of the output of the first sensor that has been confirmed to be normal and the output of the second sensor.
