Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If standard image capture devices are used to capture medical images, then the imaging process is simple and quick, but the captured images may be skewed or altered, leading to inaccurate alignment and potential injury to surrounding structures
Solution Approach 1:
The patent introduces an intermediary alignment system consisting of a target attached to the medical device, a camera to capture the target, and a processor to calculate alignment. This intermediary system mediates between the simple camera capture and the complex requirement for precise alignment verification, providing accurate orientation data without requiring the camera itself to be complex
Solution Approach 2:
The patent replaces traditional mechanical alignment methods with an optical-digital system. Instead of using complex mechanical alignment devices or manual measurement tools, the system uses a camera to capture images of a target, then uses image processing and coordinate transformation algorithms to determine the device's orientation and alignment accuracy
2Reliability
If manual alignment methods are used for medical device insertion, then the equipment required is simple, but the alignment precision is insufficient to ensure safe positioning relative to critical structures
Solution Approach 1:
The patent implements a feedback mechanism where the system captures images of a target attached to the medical device, calculates the device's orientation and position relative to pre-planned coordinates, and provides alignment verification. This feedback loop allows operators to verify alignment before insertion, improving safety without requiring overly complex real-time control systems
Solution Approach 2:
The patent performs preliminary alignment verification before the actual medical procedure. The target is attached to the device beforehand, and the alignment is checked using image capture and coordinate transformation before insertion into the patient. This preliminary action ensures safety without requiring complex real-time monitoring during the procedure
3Measurement precision
If multiple views are captured to ensure accurate three-dimensional alignment, then the alignment precision is improved, but the time required for image capture and processing increases
Solution Approach 1:
The patent uses coordinate transformation to convert two-dimensional captured images into three-dimensional orientation data. By capturing the target from different views and transforming the coordinates mathematically, the system determines the device's three-dimensional orientation without requiring physically complex multi-angle imaging setups, thus saving time while maintaining precision
