Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If treatment plans are sequentially downloaded and executed one by one, then the control process is simple, but the treatment cycle time increases and treatment efficiency decreases
Solution Approach 1:
The system performs preliminary actions by batch downloading and preparing multiple treatment plans before execution. The control device retrieves multiple treatment plans from the treatment plan library and prepares them in advance, so that when execution is needed, the plans are ready and can be executed without sequential delays, thus improving treatment efficiency while maintaining controlled complexity through automated batch processing
Solution Approach 2:
The invention merges multiple treatment plan execution operations into a unified batch processing system. Instead of sequentially handling each treatment plan individually, the system combines multiple plans into a single batch operation, allowing the focused treatment head and conformal treatment head to execute their respective plans simultaneously, thereby reducing total treatment cycle time
2Loss of time
If multiple treatment plans are batch acquired and executed simultaneously, then treatment cycle time is reduced, but the control process becomes more complex
Solution Approach 1:
The control device performs self-service by automatically examining treatment plans and validating their correctness before execution. The system independently checks treatment parameters, verifies plan compatibility, and ensures all necessary conditions are met without requiring manual intervention, thus simplifying the operational burden on users while enabling efficient batch processing that reduces treatment cycle time
Solution Approach 2:
The system implements feedback mechanisms where the control device examines treatment plans, validates their parameters, and provides automatic confirmation or rejection based on predefined criteria. This automated feedback loop ensures that only valid plans proceed to execution, maintaining operational simplicity while enabling batch processing to reduce time loss
3Reliability
If treatment plans are examined and validated before execution, then treatment safety is improved, but the processing time increases
Solution Approach 1:
The control device performs treatment plan examination and validation as a preliminary action before execution. By checking treatment parameters, verifying plan correctness, and ensuring safety conditions are met in advance during the batch preparation phase, the system ensures treatment safety without delaying the actual execution, as the validation is completed beforehand
Solution Approach 2:
The invention merges the examination and validation operations into the batch processing workflow. Multiple treatment plans are examined and validated simultaneously as part of the batch operation rather than sequentially, which maintains treatment safety through comprehensive validation while minimizing time loss through parallel processing of validation tasks
