Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a traditional dental endoscope uses only one camera unit, then the device structure is simple, but it cannot acquire complete three-dimensional image information for digital tooth modeling
Solution Approach 1:
The patent combines multiple camera units (at least two) into a single dental endoscope device, merging their functions to simultaneously capture multiple views of the oral cavity. This integration enables comprehensive three-dimensional image acquisition while maintaining a unified device structure, resolving the contradiction between measurement precision and device complexity.
Solution Approach 2:
The patent transitions from single-camera two-dimensional imaging to multi-camera three-dimensional imaging by adding spatial dimensionality. The calibrated camera units capture images from different angles simultaneously, creating three-dimensional image information that enables digital tooth modeling, thus improving measurement precision through dimensional enhancement.
2Reliability
If a dental endoscope requires sequential scanning of upper and lower dentition according to a set sequence, then complete tooth impression can be obtained, but the operation requirement is high and professional operation is needed
Solution Approach 1:
The patent performs preliminary calibration of the camera units' relative positions before actual imaging. This pre-established geometric relationship allows the system to automatically determine spatial information without requiring operators to manually follow complex scanning sequences, thereby maintaining reliable complete tooth impression acquisition while significantly improving ease of operation.
Solution Approach 2:
The system enables self-service operation by automatically acquiring complete tooth impressions without requiring professional operators to follow strict scanning sequences. The calibrated multi-camera setup autonomously captures all necessary dental views, allowing ordinary users to obtain complete tooth impressions independently, thus improving ease of operation while maintaining reliability.
3Loss of information
If a dental endoscope uses one camera unit to capture images, then the device is simple to operate, but it cannot provide reference images for angle and position determination
Solution Approach 1:
The patent merges multiple camera units with calibrated relative positions into a single integrated imaging system. This combination allows the device to simultaneously capture multiple images that serve as mutual references for angle and position determination, preventing information loss while avoiding the complexity of separate devices.
Solution Approach 2:
The calibrated geometric relationship between camera units acts as an intermediary that enables angle and position determination. This pre-established spatial configuration serves as a reference framework, allowing the system to automatically determine imaging parameters without requiring additional complex equipment or manual measurement tools.
4Measurement precision
If a dental endoscope requires professional operation for sequential scanning, then accurate tooth impression can be obtained, but self-service impression is difficult to realize
Solution Approach 1:
The patent performs preliminary calibration of camera unit positions and establishes reference frameworks before actual use. This pre-prepared configuration enables the system to automatically determine spatial information during operation, maintaining accurate tooth impression while eliminating the need for professional operators to follow complex procedures, thus enabling self-service capability.
Solution Approach 2:
The system is designed to perform self-service tooth impression by automatically capturing and processing dental images without requiring professional operators. The calibrated multi-camera setup autonomously acquires complete tooth impressions with accurate measurement precision, allowing ordinary users to independently complete the entire impression process, thereby resolving the contradiction between measurement precision and self-service capability.
