Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a simple digital form is displayed to prompt the current operation state, then the device complexity is reduced, but the information prompt effectiveness deteriorates
Solution Approach 1:
The patent transitions from simple digital display to three-dimensional visual modeling, adding spatial dimension to the prompt information. The system constructs a 3D model of the operation area that visually represents the relationship between the radiofrequency probe and target tissue, enabling users to comprehend the operation state more intuitively and completely without excessive complexity
Solution Approach 2:
The patent creates a virtual copy (3D visual model) of the physical operation area to display on the user interface. This digital twin reflects the real-time state of the radiofrequency ablation process, allowing users to observe the operation state indirectly through the visualized model, thereby improving information completeness while maintaining manageable system complexity
2Measurement precision
If multiple probes are used to obtain real-time physical characteristic data, then the measurement precision is improved, but the device complexity increases
Solution Approach 1:
The catheter is divided into multiple probes distributed at different positions, each independently measuring physical characteristics at its location. This segmentation allows comprehensive coverage of the operation area with high measurement precision while keeping each individual probe simple in structure
Solution Approach 2:
Multiple probes perform the same measurement function simultaneously, creating a redundant yet coordinated sensing system. Each probe is universally designed with identical structure and function, simplifying individual probe design while achieving enhanced overall measurement precision through multi-point data collection
