Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional visual guidance methods are used for balloon dilation, then the surgical procedure can be performed, but the positioning precision and orientation accuracy are insufficient
Solution Approach 1:
The patent replaces traditional mechanical visual guidance systems with an electromagnetic field-based sensor coil system. The sensor coil detects electromagnetic fields to determine the balloon dilation device's position and orientation in three-dimensional space, providing precise tracking without relying on mechanical markers or visual line-of-sight methods.
Solution Approach 2:
The patent introduces an electromagnetic field as an intermediary between the balloon dilation device and the tracking system. The sensor coil on the device interacts with electromagnetic fields generated by external tracking systems, enabling indirect but precise measurement of device position and orientation without direct mechanical contact or visual observation.
2Productivity
If multiple invasive steps are used for sinus and Eustachian tube dilation, then the procedure can be completed, but the surgery time is extended
Solution Approach 1:
The patent implements real-time feedback through the sensor coil system, which continuously monitors the balloon dilation device's position and orientation during the procedure. This feedback is displayed to the surgeon, enabling immediate adjustments and eliminating the need for multiple trial insertions or repeated positioning attempts, thereby reducing overall surgery time.
Solution Approach 2:
The patent enables preliminary positioning verification through electromagnetic field detection before actual dilation begins. The sensor coil allows the surgeon to confirm correct device placement and orientation in advance, preventing the need for corrective maneuvers during the dilation process and streamlining the overall procedure.
