Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the control module is provided separately from the sensor, then the radiation dose monitoring and analysis can be performed, but the handleability of the imaging device becomes worse and the control module becomes an obstacle when the sensor is placed in the oral cavity
Solution Approach 1:
The patent combines the control module and sensor into a single integrated imaging device housed in one case. This merging eliminates the physical obstacle of a separate control module in the oral cavity while maintaining all radiation monitoring and control functions through internal integration and wireless communication capabilities.
2Ease of operation
If the sensor and control module are housed in a single case, then the handleability of the imaging device is improved, but the imaging device may generate heat in the oral cavity due to the analysis of radiation dose signal being performed by the control module placed in the oral cavity
Solution Approach 1:
The patent extracts the heavy computational analysis functions from the imaging device and relocates them to an external computing device. The imaging device only performs basic signal acquisition and transmission, while the external device handles the complex radiation dose analysis, thereby minimizing heat generation in the oral cavity.
3Productivity
If the control module is placed in the oral cavity to perform real-time analysis, then the imaging end timing can be determined, but the processing load of the controller increases and the size of the imaging device increases
Solution Approach 1:
The patent introduces an external computing device as an intermediary between the imaging device and the final image processing. This intermediary handles the computationally intensive radiation dose analysis and imaging timing determination, allowing the imaging device controller to remain simple while maintaining high imaging efficiency through seamless communication.

AI summary
An intra-oral imaging system includes an imaging device and a control device. The imaging device includes an imager, a controller, and a case in which the imager and the controller are housed. The imager performs imaging detection for detecting radiation in order to acquire an image of an object and monitoring detection for detecting radiation in order to monitor the dose of radiation. The controller transmits an imaging signal and a monitoring signal to the control device, the imaging signal acquired by the imaging detection and the monitoring signal acquired by the monitoring detection. The control device receives the imaging signal and the monitoring signal, and transmits a control command to the controller, the control command generated based on the monitoring signal. The controller controls the imager according to the control command.
