Innovation Solution
A mask positioning assembly comprising a cradle frame, an adapter frame, and a positioning mask, where the adapter frame can connect to different positioning system support frames, allowing the same assembly to be used across various systems, ensuring accurate and efficient patient head positioning without frequent replacements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If different mask positioning assemblies are used for various equipment types (radiotherapy and image acquisition systems), then the positioning can be equipment-specific, but the cost increases and operational efficiency decreases due to frequent replacements
Solution Approach 1:
The mask positioning assembly is designed with a universal adapter frame that can connect to multiple types of positioning system support frames (both radiotherapy and image acquisition systems). This allows a single mask positioning assembly to serve multiple equipment types, eliminating the need for frequent replacements and improving operational efficiency while maintaining equipment-specific positioning capabilities
2Reliability
If different mask positioning assemblies are used for various equipment types, then equipment-specific optimization is possible, but the overall cost increases
Solution Approach 1:
By designing the mask positioning assembly with a universal adapter frame that interfaces with multiple support frame types, the invention reduces the total number of assemblies needed from multiple equipment-specific units to a single multi-compatible unit, thereby reducing costs while maintaining positioning accuracy through proper adaptation to each system
3Adaptability or versatility
If multiple mask positioning assemblies are maintained for different systems, then system-specific requirements can be met, but device complexity and management difficulty increase
Solution Approach 1:
The invention consolidates multiple equipment-specific assemblies into a single universal mask positioning assembly with an adapter frame that can interface with different support frame types. This reduces the variety of assemblies from multiple specialized units to one multi-functional unit, simplifying device management while maintaining compatibility with different systems
