Radiation Irradiation Device With Remote Unit Attachment Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing radiation irradiation devices require users to manually check the attachment/detachment state of the remote operation unit, which is burdensome and increases the risk of loss.
Innovation Solution
The device incorporates a processor that detects the attachment/detachment state of the remote operation unit and executes controls to notify the user through a display or display lamp, ensuring the unit is properly attached before operations like power-off or irradiation are performed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the remote operation unit is made detachable from the device main body, then the ease of operation is improved, but the reliability deteriorates due to the risk of loss and the need for manual attachment checks
Solution Approach 1:
The device incorporates a detection unit that automatically detects the attachment/detachment state of the remote operation unit and provides feedback to the control unit. This automatic feedback mechanism eliminates the need for manual attachment checks by the user, resolving the contradiction between detachability and reliability.
Solution Approach 2:
The system performs self-monitoring of the attachment state through the detection unit, which automatically tracks and reports the attachment status without requiring user intervention. This self-service approach maintains reliability while preserving the detachable design for ease of operation.
2Reliability
If manual attachment checks are required, then the reliability is maintained, but the ease of operation deteriorates due to additional user burden
Solution Approach 1:
The detection unit continuously monitors and provides real-time feedback on the attachment state to both the control unit and the user through notifications. This automated verification system maintains reliability while eliminating the manual check burden from the user.
Solution Approach 2:
The manual mechanical checking process is replaced with an automated detection system using sensors and electronic communication. The detection unit automatically determines attachment state through electrical or magnetic field detection, substituting the manual mechanical verification process.
3Ease of operation
If the device provides automatic attachment state detection and notification, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The detection unit serves multiple functions: it detects attachment state, communicates with the control unit, and triggers notifications. By making this component multi-functional, the patent reduces the need for separate dedicated components, thereby limiting the increase in device complexity while achieving automatic detection.
Solution Approach 2:
The detection, control, and notification functions are merged into an integrated system where the detection unit works in conjunction with the existing control unit and notification unit. This merging approach leverages existing components to minimize additional complexity while achieving the desired automatic detection capability.
