Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If an existing extracorporeal radiotherapy apparatus is used, then radiation treatment can be delivered, but the apparatus cannot be moved and requires a dedicated shielding room, making it unsuitable for intraoperative radiotherapy
Solution Approach 1:
The radiotherapy apparatus is designed with a movable C-shaped arm linear accelerator that can be repositioned and used in both extracorporeal radiotherapy settings with shielding rooms and intraoperative radiotherapy settings in operating rooms, eliminating the need for separate dedicated equipment for each application
2Measurement precision
If an existing intraoperative radiotherapy apparatus is used, then radiotherapy can be delivered in the operating room, but the structure is complex and lacks image guidance, resulting in poor precision
Solution Approach 1:
The apparatus integrates the C-shaped arm linear accelerator with an optical imaging system into a single unified device, combining radiation delivery and imaging capabilities to achieve high-precision intraoperative radiotherapy without requiring separate complex systems
Solution Approach 2:
The optical imaging system provides real-time visualization and feedback for positioning the radiation beam accurately on the tumor target during intraoperative radiotherapy, enabling precise beam targeting while maintaining operational simplicity
