Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple devices and steps are used for intraoral scanning and photogrammetry, then comprehensive data capture is achieved, but device complexity and procedure time increase
Solution Approach 1:
The patent combines multiple camera sensors (front, back, left, right, and tip cameras) into a single intraoral photogrammetry device. This merging of multiple sensing functions into one integrated device eliminates the need for separate scanning and photogrammetry devices, thereby reducing device complexity while maintaining comprehensive data capture capability.
Solution Approach 2:
The single intraoral photogrammetry device performs multiple functions including photogrammetry capture, 3D scanning, color mapping, and bite registration. By making the device universal and multi-functional, it replaces multiple specialized devices, reducing overall system complexity while ensuring complete oral data acquisition.
2Reliability
If multiple steps and devices are used, then complete oral data is captured, but patient chair time and discomfort increase
Solution Approach 1:
By merging photogrammetry, scanning, and bite registration functions into a single device that can be used in one procedure, the patent eliminates multiple sequential steps. This allows all necessary oral data to be captured during a single patient visit, significantly reducing chair time while maintaining complete data acquisition.
Solution Approach 2:
The device captures all necessary data (photograms, 3D models, color maps, and bite registration) in a single procedure before the patient leaves the chair. This preliminary capture of all required information in one go eliminates the need for follow-up appointments or additional scanning sessions.
3Measurement precision
If traditional scanning methods are used, then detailed oral structures are captured, but obstructed views in complex regions occur
Solution Approach 1:
The device segments the oral cavity into multiple viewing zones by positioning cameras at different locations (front, back, left, right, and tip). This segmentation of sensing perspectives allows each camera to capture specific anatomical regions without obstruction, with the back camera specifically addressing previously hidden areas.
Solution Approach 2:
The patent adds spatial dimensionality to data capture by positioning cameras in three-dimensional space around the oral cavity rather than using a single linear scanning path. This multi-dimensional arrangement of sensors eliminates line-of-sight obstructions and captures complete anatomical detail from all angles simultaneously.
4Ease of operation
If single-click capture is implemented, then user-friendliness and speed improve, but processing complexity increases
Solution Approach 1:
The system performs automatic processing of captured photogrammetry data, 3D models, and bite registration information without requiring manual intervention. The device and associated software automatically align, merge, and process all captured data streams, making the complex processing transparent to the user while maintaining ease of operation.
