Radiation Irradiation Apparatus Attachment Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing radiation irradiation apparatuses do not consider the displacement of the holding portion when attached to a decubitus table, leading to instability and potential movement during radiation therapy.
Innovation Solution
A radiation irradiation apparatus with a holding portion that can be displaced in various directions (up-down, horizontal, rotation) while attached to a decubitus table, featuring a restriction mechanism that releases displacement restrictions when the apparatus is securely attached.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the radiation irradiation apparatus is made movable to travel independently from the decubitus table, then the ease of operation and adaptability are improved, but the stability of the apparatus during operation deteriorates
Solution Approach 1:
The apparatus transitions between mobile and fixed states through the attachment mechanism. When not in use, the apparatus can travel independently on wheels for ease of positioning. When attached to the decubitus table, the apparatus becomes fixed to ensure stability during radiation therapy operations.
Solution Approach 2:
The apparatus is divided into separable components: a mobile base unit with wheels for independent travel, and an attachment interface that connects to the decubitus table. This segmentation allows the apparatus to function in both mobile and fixed modes as needed.
2Ease of operation
If the holding portion is allowed to displace freely to accommodate various positions, then the ease of operation is improved, but the stability and precision of radiation delivery deteriorates
Solution Approach 1:
The holding portion transitions between a restricted state during travel (where displacement is limited to maintain stability) and a free displacement state during operation (when attached to the table, allowing position adjustment for precise radiation delivery).
Solution Approach 2:
The restriction mechanism is designed to automatically release displacement restrictions when the attachment mechanism engages with the decubitus table. This preliminary action ensures that the holding portion is free to displace to precise positions when needed, while maintaining stability during transport.
3Stability of the object's composition
If the restriction mechanism is always active to prevent displacement, then the stability is improved, but the ease of operation and adaptability deteriorates
Solution Approach 1:
The restriction mechanism dynamically changes its state based on the attachment status. When the apparatus is attached to the decubitus table, the restriction mechanism releases to allow holding portion displacement for precise positioning. When detached, the restriction mechanism remains active to prevent unwanted displacement and maintain stability.
Solution Approach 2:
The attachment mechanism provides feedback to the restriction mechanism, automatically triggering the release of displacement restrictions when attachment is detected. This ensures that stability and adaptability are maintained in their respective appropriate states without manual intervention.

AI summary
A radiation irradiation apparatus that is configured to independently travel from a decubitus table on which a subject can be placed, the radiation irradiation apparatus including: an attachment portion that allows the radiation irradiation apparatus to be attached to and detached from the decubitus table; a radiation irradiation portion capable of emitting radiation to the subject; a holding portion that is provided at a distal end portion thereof with the radiation irradiation portion and that holds the radiation irradiation portion to be displaceable; and a restriction mechanism that restricts displacement of the holding portion, in which the radiation irradiation apparatus is attached to the decubitus table through the attachment portion to release restriction of the displacement in the restriction mechanism.
