Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If manual movement of scanners is used, then device complexity is reduced, but measurement precision deteriorates
Solution Approach 1:
The system uses AI to automatically track the scanner's movement and generate guided paths without requiring manual input or user intervention. The AI model processes images, identifies teeth, and autonomously creates scanning guidelines, allowing the system to serve itself rather than relying on manual operation for precision
Solution Approach 2:
The patent replaces manual mechanical control with AI-based automated tracking. Instead of relying on the operator's hand movements and manual navigation, the system uses image processing and machine learning algorithms to automatically follow the scanner through the mouth and generate precise guided paths
2Measurement precision
If extensive user training is required, then measurement precision can be improved, but ease of operation deteriorates
Solution Approach 1:
The AI system performs self-alignment and automatic guided path generation without requiring user knowledge of scan paths or manual navigation techniques. The system autonomously processes images, identifies dental structures, and creates scanning guidelines, eliminating the need for extensive user training while maintaining high scan accuracy
Solution Approach 2:
The system performs preliminary image processing, tooth identification, and guided path generation before the actual scanning begins. By pre-processing the images and automatically creating the scanning guidelines in advance, the system eliminates the need for users to learn complex scan paths during training
3Ease of operation
If break in contact with predefined scan path occurs, then ease of operation is improved, but measurement precision deteriorates
Solution Approach 1:
The system continuously processes images during scanning and provides real-time feedback by generating guided paths that adapt to the scanner's actual movement. The AI model monitors the scanning process and dynamically adjusts the guided paths to maintain accuracy even when the scanner deviates from predefined paths, allowing operational flexibility while preserving measurement precision

AI summary
The present technology relates to devices, methods and systems for scanning the oral cavity, in particular for dental applications; and for providing 3-dimensional (3D) data that makes it easier for a dental professional to scan the oral cavity of a patient, without the need for extensive training in specialized equipment and software systems. A system or method herein can include a visual display, in which a generated 3D scan model is overlaid over a 3D template model, such that a user can look at it and be guided by it during the scanning process. Such devices, methods and systems can help a dental professional in any dental procedure, for example, to develop a dental treatment such as orthodontics, fitting a prosthesis such as a crown or bridge, or treating a cavity. The technology also relates to methods of scanning the oral cavity of a patient.
