Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional radiotherapy methods face challenges in accurately and efficiently positioning patients with high radiation-resistant tumors, leading to excessive damage to normal tissues and prolonged preparation times due to complex mounting structures and difficulty in adjusting irradiation locations.
Innovation Solution
A supporting device with a main plate and adapting assembly that allows rapid and accurate mounting to different bearing devices, enabling precise positioning and reducing preparation time by using detachable and adjustable components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a complex mounting structure is used to ensure accurate positioning of the supporting device on bearing devices, then positioning accuracy is improved, but device complexity and preparation time increase
Solution Approach 1:
The supporting device is divided into a main plate and a separate adapting assembly. The adapting assembly is further segmented into adapting members that can be selectively mounted on the main plate. This segmentation allows the positioning function to be separated from the supporting function, enabling accurate positioning without requiring the entire supporting device to be complex.
Solution Approach 2:
The adapting assembly is designed as a universal interface that can connect the main plate to multiple different types of bearing devices (treatment loading tables, simulation loading tables, image loading tables). The adapting members provide standardized mounting interfaces that work across different bearing device models, eliminating the need for device-specific complex mounting structures.
2Adaptability or versatility
If multiple bearing devices with different models are used to accommodate various treatment scenes, then adaptability is improved, but mounting difficulty and preparation time increase
Solution Approach 1:
The adapting assembly serves as a universal adapter that interfaces with multiple bearing device models including treatment loading tables, simulation loading tables, and image loading tables. The same adapting assembly can be used across different bearing devices, providing consistent mounting capability without requiring operator training for each specific device model.
Solution Approach 2:
The adapting assembly acts as an intermediary component between the main plate and the bearing device. It mediates the connection between the standardized main plate interface and the various bearing device interfaces, simplifying the mounting operation to a single standardized interface interaction regardless of the bearing device type.
3Adaptability or versatility
If the irradiation location is adjusted by moving and repositioning the patient, then treatment flexibility is improved, but positioning accuracy and treatment effect are compromised
Solution Approach 1:
The system enables dynamic reconfiguration by allowing the main plate to be detached from the bearing device and remounted at different positions. The adapting assembly maintains secure connection during movement, and the main plate can be quickly repositioned on the same or different bearing devices to accommodate changes in treatment requirements while preserving positioning accuracy.
Solution Approach 2:
By separating the supporting function (main plate) from the positioning function (adapting assembly), the system allows the main plate to be easily detached and remounted at different locations. This segmentation enables rapid repositioning for different irradiation targets without compromising the precision provided by the adapting assembly's standardized interfaces.

AI summary
Provided are a supporting device, a method for positioning a supporting device, and a radiotherapy system. The supporting device includes a main plate and an adapting assembly, where the main plate is used for at least partially bearing an irradiated body, the main plate defines an extension direction, and the main plate includes a supporting surface arranged in the extension direction, a side surface connected to the supporting surface, and a back surface arranged opposite the supporting surface; and the adapting assembly is arranged on the back surface and/or the side surface of the main plate and used for connecting the main plate to a predetermined location. The main plate is used for being loaded onto a bearing device for bearing the irradiated body, and the main plate can be matched and positioned to bearing devices in different scenes or in different treatment phases by the adapting assembly. A worker is only required to position the main plate to a to-be-used bearing device. A diseased part supporting assembly is mounted by additionally arranging the main plate to the bearing device, such that a problem that it is difficult to mount the diseased part supporting assembly to an existing bearing device in the past is resolved, and no complex mounting structure is required to be additionally arranged on the bearing device.
