Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a simulation image obtained in advance by an intravascular examination simulation apparatus is used for displaying treatment information, then the overall situation of treatment can be grasped, but the simulation result of blood flow before surgery becomes different from the actual blood flow during surgery due to shape changes of the organ
Solution Approach 1:
The system performs preliminary blood flow simulation based on pre-acquired 3D model data before surgery to establish baseline blood flow characteristics. This preliminary analysis allows comparison with actual intraoperative blood flow measurements, enabling verification of simulation accuracy and real-time adjustment of treatment plans based on the difference results.
2Ease of operation
If the simulation result of blood flow before surgery is not compared with the result of actual blood flow during surgery, then the treatment planning process is simpler, but real-time feedback and adjustment during surgery cannot be achieved
Solution Approach 1:
The system implements a feedback mechanism by continuously comparing simulation results with actual blood flow measurements during surgery. The difference detection unit quantifies discrepancies between predicted and actual blood flow, providing real-time feedback to surgeons for immediate adjustment of treatment plans, thereby improving both surgical outcomes and time utilization.
3Measurement precision
If the shape of an actual organ is used for blood flow analysis during surgery, then the blood flow analysis reflects actual conditions, but the comparison with pre-surgical simulation results becomes difficult due to shape changes
Solution Approach 1:
The system introduces a difference detection unit as an intermediary that bridges the gap between pre-surgical simulation results and intraoperative actual measurements. This intermediary component automatically handles the complex task of comparing blood flow data despite organ shape changes, eliminating the need for manual alignment and reducing system complexity while maintaining high measurement precision.
