Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a simple intraoral device is used for oral health monitoring, then ease of operation is improved, but measurement precision deteriorates
Solution Approach 1:
The patent combines multiple diagnostic functions (caries detection, plaque detection, functional blood mapping, whiteness measurements, hydration measurements) into a single intraoral device that uses spectral imaging technology. This merging of multiple diagnostic capabilities into one device maintains ease of operation while achieving comprehensive and precise oral health monitoring through AI-powered analysis of spectral data.
Solution Approach 2:
The device employs spectral imaging that captures images at multiple wavelengths (spectral channels) to detect various oral health parameters. By analyzing the spectral signature of light reflected from different oral tissues at different wavelengths, the device achieves high measurement precision for detecting caries, plaque, blood oxygenation, and other parameters while maintaining a simple user interface.
2Measurement precision
If comprehensive oral health monitoring functions are added to the device, then measurement precision is improved, but device complexity worsens
Solution Approach 1:
The device incorporates AI-powered automated analysis that processes spectral imaging data and provides diagnostic results without requiring manual interpretation by users. The system automatically detects caries, plaque, and other oral health conditions, and provides personalized recommendations, enabling comprehensive monitoring while keeping the user interface simple and easy to operate.
Solution Approach 2:
The intraoral device is designed as a multi-functional platform that performs multiple diagnostic functions (caries detection, plaque detection, functional blood mapping, whiteness measurements, hydration measurements) using a unified spectral imaging approach. This universal design achieves comprehensive oral health monitoring while consolidating multiple functions into one device rather than requiring separate specialized tools.
3Measurement precision
If spectral imaging with multiple wavelengths is used, then measurement precision is improved, but use of energy worsens
Solution Approach 1:
The device captures spectral images at multiple wavelengths in a sequential or pulsed manner rather than continuously illuminating at all wavelengths simultaneously. The light source emits light at different wavelengths in sequence, and the sensor captures reflected light at each wavelength, reducing total energy consumption while still acquiring comprehensive spectral data for accurate oral health diagnosis.

AI summary
An intraoral device (100) for determining oral health characteristics is provided. The device includes a light source (106) configured to emit light in a plurality of wavelengths within or about the oral cavity and a matrix array multispectral sensor (102) configured to detect a plurality of spectral channels of a spectral image. Each of the plurality of spectral channels may allow transmission of a corresponding wavelength. The device may include a processor (1100) configured to identify the detected plurality of spectral channels of the spectral image relating to the oral cavity. Based on the detected plurality of spectral channels, the processor may cause the light source to adjust the light emitted within or about the oral cavity to modify a signal to noise ratio and/or an image calibration of a subsequent spectral image. The matrix array multispectral sensor may capture the subsequent spectral image relating the oral cavity in the adjusted emitted light.
