Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing radiation systems for imaging and treatment generate significant radiation, requiring extensive shielding in facilities, which is costly and limits their placement due to weight and structural considerations.
Innovation Solution
A radiation system with a rotatable capsule and shielding material that blocks at least 98% of radiation, allowing for adjustable radiation delivery angles and reduced shielding needs, enabling the system to be used in various locations without extensive retrofitting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If existing radiation systems are used for imaging and treatment, then radiation delivery capability is achieved, but extensive shielding is required in facilities
Solution Approach 1:
The patent extracts the shielding function from the building structure and relocates it to a portable shield positioned within the treatment room. This separates the radiation containment function from the permanent facility, allowing the building to remain unspecialized while still providing safe radiation delivery.
Solution Approach 2:
The patent introduces a portable shield as an intermediary element between the radiation source and the building structure. This mediator absorbs or blocks radiation locally, preventing it from reaching the building walls and eliminating the need for integrated shielding construction.
2Reliability
If extensive shielding is provided in facilities, then radiation safety is ensured, but cost and structural requirements increase
Solution Approach 1:
The shielding function is extracted from the permanent building structure and placed in a movable, standalone shield. This reduces the weight and structural burden on the building while maintaining radiation safety through the portable containment solution.
Solution Approach 2:
The patent transforms the shielding from a static, permanent building feature to a dynamic, movable portable unit. This allows the shield to be repositioned or removed as needed, reducing permanent structural requirements while maintaining safety during operation.
3Productivity
If radiation systems are installed in existing buildings, then treatment capability is provided, but building retrofitting is required
Solution Approach 1:
The patent extracts the shielding requirement from the building retrofitting process and places it in a portable shield that can be brought to any location. This allows treatment capability to be added to existing buildings without structural modifications or specialized construction.
Solution Approach 2:
The portable shield design creates a universal solution that can be deployed in any existing building regardless of its original construction. The same shield unit can be moved between different locations, providing treatment capability without requiring each building to be customized or retrofitted.

AI summary
A radiation system includes: a first support; a first structure rotatably coupled to the first support so that the first structure is rotatable about a first axis relative to the first support; a second structure rotatably coupled to the first structure so that the second structure is rotatable about a second axis that forms a non-zero angle relative to the first structure; and a first radiation source connected to the second structure; wherein the first structure and the second structure are parts of a capsule for accommodating at least a portion of a patient.
