Foldable Spacing Unit Control in Radiation Irradiation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing radiation irradiation devices require users to manually check and ensure the spacing ensuring unit is in the correct state before irradiation, which is burdensome and can lead to unintended irradiation if not properly set up.
Innovation Solution
A radiation irradiation device with a spacing ensuring unit that can switch between unfolded and storage states, equipped with sensors and a processor to automatically detect and control the unit's state, preventing irradiation when in the storage state and allowing it only when unfolded.

Engineering Contradiction Analysis
1Volume of moving object
If the spacing ensuring unit is made foldable to improve storability and portability, then the device becomes more compact and easier to store, but the user must manually check the unit's state before irradiation which increases operational burden
Solution Approach 1:
The system performs self-check of the spacing ensuring unit state through sensors and processors, eliminating the need for manual user verification. The device automatically detects whether the unit is extended or folded and controls irradiation accordingly, making the system serve itself rather than requiring continuous user attention.
Solution Approach 2:
The system implements automatic feedback mechanisms where sensors continuously monitor the spacing ensuring unit position and provide real-time information to the control system. This feedback loop enables the device to automatically adjust its state and provide user notifications, replacing manual checking with automated information return to the user.
2Device complexity
If manual checking of the spacing ensuring unit is required before irradiation, then the device structure can be simpler, but the risk of unintended irradiation increases and user convenience decreases
Solution Approach 1:
Sensors and processors act as intermediaries between the spacing ensuring unit and the irradiation control system. These intermediary components automatically verify the unit state and mediate the decision-making process, preventing direct manual operation errors and ensuring safety without significantly complicating the overall device structure.
Solution Approach 2:
The control system performs self-verification of the spacing ensuring unit state through integrated sensors, eliminating reliance on manual user checking. This self-service mechanism automatically ensures safety conditions are met before permitting irradiation, reducing both structural complexity and safety risks.
3Ease of operation
If the processor automatically detects and controls based on the spacing ensuring unit state, then user intervention is reduced and convenience is improved, but the device complexity increases
Solution Approach 1:
Manual mechanical checking operations are replaced with automated sensor-based detection and processor-controlled systems. Electronic and optical sensing mechanisms substitute for manual visual inspection, reducing user burden while the modular sensor-processor architecture manages complexity through standardized components rather than custom mechanical solutions.

AI summary
A radiation irradiation device includes: a device main body that irradiates a subject with radiation; a spacing ensuring unit that is a member extending from the device main body in an emission direction of the radiation to ensure a spacing between the subject and the device main body and is switchable between an unfolded state in which a length extending from the device main body is a predetermined length and a storage state in which a length from the device main body is shorter than the predetermined length with a displacement of at least a part of a movable portion; and a processor, in which the processor detects a state including the storage state and the unfolded state of the spacing ensuring unit, and executes a control of an operation of the device main body according to the detected state.
