Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If multiple static fields are used in proton therapy planning, then dose delivery precision to target is improved, but data transfer time and treatment session length increase
Solution Approach 1:
The patent combines multiple static field data files into a single composite dynamic field data file. This merging process consolidates the data representation of multiple beams and fields into one unified data structure, reducing the number of separate data transfers required while preserving the dosimetric accuracy of individual fields through sequential delivery instructions embedded in the composite file.
Solution Approach 2:
The patent transitions from static field representations to a dynamic field approach where a single data file contains sequential instructions for delivering multiple beams. The system dynamically switches between different beam configurations within the treatment session using the composite field sequencing technique, allowing flexible delivery of multiple static fields through a dynamic data transfer mechanism.
2Manufacturing precision
If multiple static fields are used in proton therapy planning, then dose delivery precision to target is improved, but clinical efficiency and patient throughput decrease
Solution Approach 1:
The patent merges multiple static field data files into a single composite dynamic field data file, reducing the overhead of processing and transferring multiple separate files. This consolidation maintains the precision of individual field deliveries while improving workflow efficiency by reducing data management complexity and transfer operations.
Solution Approach 2:
The patent enables continuous treatment delivery by sequencing multiple beams within a single data transfer operation. The composite field approach allows the treatment system to proceed through multiple beam deliveries without interruption for repeated data transfers, maintaining continuous useful action throughout the treatment session.
3Measurement precision
If multiple separate data files are transferred for each static field, then data accuracy for each field is maintained, but transmission time increases
Solution Approach 1:
The patent combines multiple separate data files into one composite data file while preserving the accuracy of individual field specifications. The composite file contains structured sequential instructions that maintain the dosimetric parameters and delivery specifications of each original static field, ensuring data accuracy is not compromised by the merging process.
Solution Approach 2:
The patent segments the composite data file into sequential beam delivery instructions, where each segment corresponds to a specific static field configuration. This segmentation allows the system to process and validate individual field parameters within the unified file structure, maintaining data accuracy through organized, sequential data representation.
