Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If traditional particle beam therapy systems are used, then cancer treatment can be provided, but the systems lack integration and compactness, increasing device complexity and cost
Solution Approach 1:
The patent combines multiple previously separate components (injector, synchrotron accelerator, beam transport system, targeting system, patient interface) into a single integrated charged particle beam therapy system. This merging of components achieves the desired system integration while reducing overall complexity through unified design and control.
Solution Approach 2:
The integrated system is designed to perform multiple functions within a single apparatus, including particle generation, acceleration, transport, targeting, and patient interface operations. This multi-functionality reduces the need for separate dedicated systems, thereby simplifying the overall device architecture while maintaining comprehensive cancer treatment capability.
2Device complexity
If particle beam delivery is simplified, then device complexity is reduced, but accuracy and precision of tumor targeting deteriorate
Solution Approach 1:
The system incorporates dynamic control mechanisms that allow real-time adjustment of beam parameters and targeting during treatment. This dynamic capability enables precise tumor targeting while maintaining manageable system complexity through automated control algorithms that adapt to patient-specific requirements.
Solution Approach 2:
The integrated system incorporates feedback mechanisms that monitor beam delivery parameters and patient position in real-time, allowing for automatic corrections to maintain precision. This feedback control enables accurate tumor targeting without requiring overly complex mechanical delivery systems.
3Productivity
If treatment time is reduced, then productivity increases, but the ability to deliver precise multi-axis irradiation deteriorates
Solution Approach 1:
The synchrotron accelerator enables continuous particle generation and acceleration without interruption, maintaining useful action throughout the treatment process. This continuous operation increases productivity while the automated multi-axis control system manages the complexity of precise irradiation delivery.
Solution Approach 2:
The system replaces complex mechanical multi-axis positioning mechanisms with electromagnetic field-based control for beam steering and focusing. This substitution achieves precise multi-axis irradiation control through field manipulation rather than mechanical movement, thereby reducing operational complexity while maintaining or improving treatment efficiency.
