Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If real-time control feedback is implemented for tracking treatment channels and energy emitting sources, then measurement precision and reliability are improved, but device complexity and computing resource requirements increase
Solution Approach 1:
The control system is segmented into multiple independent processing means, each dedicated to specific real-time control functions such as source tracking, channel positioning, and treatment monitoring. This segmentation allows parallel processing of multiple control tasks simultaneously, reducing the complexity burden on any single component while maintaining high measurement precision through specialized processing units.
Solution Approach 2:
The patent introduces an intermediary control architecture that acts as a mediator between the various control functions and the treatment delivery system. This intermediary layer manages the complexity by standardizing communication protocols and data formats, allowing real-time feedback from multiple sensors to be integrated and processed efficiently without overwhelming the core control system.
2Adaptability or versatility
If real-time processing of treatment status information is performed, then adaptability and treatment safety are improved, but computing time and processing speed requirements increase
Solution Approach 1:
The system performs preliminary actions by pre-calculating treatment parameters, pre-positioning control algorithms, and pre-establishing safety thresholds before treatment begins. This allows the real-time control system to operate with simplified decision-making logic during treatment, reducing computing time while maintaining high adaptability through pre-configured response protocols for various treatment scenarios.
Solution Approach 2:
The control system implements periodic sampling and processing of treatment status information at optimized intervals rather than continuous processing. This periodic action is calibrated to detect critical changes while minimizing computational overhead, allowing the system to maintain treatment adaptability by checking key parameters at strategically determined moments without consuming excessive computing resources.
3Productivity
If multiple processing means are operated simultaneously for treatment planning and control, then productivity and treatment efficiency are improved, but resource management complexity increases
Solution Approach 1:
Each processing means is assigned specific local quality characteristics and functional responsibilities tailored to its role in the treatment workflow. For example, treatment planning processors are optimized for computational geometry and dose calculation, while real-time control processors are optimized for rapid data acquisition and immediate response. This specialization allows parallel operation of multiple processing means with improved resource utilization and reduced management complexity through clear functional boundaries.
