Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual parameter determination and workflow management are used in MRgRT systems, then flexibility and adaptability are maintained, but system complexity increases and efficiency decreases
Solution Approach 1:
The patent segments the complex MRgRT workflow into distinct phases (imaging, planning, treatment) and organizes parameters into structured lists associated with each phase. This segmentation allows systematic management of numerous parameters while maintaining clarity and reducing overall system complexity through modular organization.
Solution Approach 2:
The patent implements automated parameter determination by changing from manual parameter entry to automated parameter generation based on diagnosis-driven workflows. The system automatically selects and configures parameters from predefined lists based on treatment prescriptions, eliminating manual configuration while maintaining full adaptability.
2Extent of automation
If automated parameter determination is implemented, then planning efficiency improves, but system complexity increases
Solution Approach 1:
The patent prepares predefined parameter lists and workflow templates in advance before actual treatment planning. These pre-configured parameters and workflows are stored and can be automatically selected and applied based on diagnosis and treatment prescription, enabling automated parameter determination without requiring complex real-time decision-making logic.
Solution Approach 2:
The system uses template-based workflow copying where predefined workflow patterns are replicated and adapted for specific patient cases. This allows automated parameter determination through template instantiation while keeping the underlying system architecture manageable through reuse of proven workflow patterns.
3Manufacturing precision
If diagnosis-driven workflows are used, then treatment precision improves, but workflow flexibility may be reduced
Solution Approach 1:
The patent implements dynamic workflow adaptation where diagnosis-driven templates can be automatically adjusted based on specific patient parameters and treatment prescriptions. The system maintains flexibility by allowing parameter modifications within predefined ranges and enabling adaptive selection of different parameter sets based on individual patient needs while preserving treatment precision.
