Dental Camera Acoustic Feedback for Registration Monitoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dental camera measurement methods require users to constantly monitor a screen for feedback on recording status and conditions, leading to longer survey times due to the need for visual confirmation of registration accuracy and recording quality.
Innovation Solution
A method using a dental camera that generates acoustic feedback via a sound generator to inform the user about registration status and recording conditions, allowing for automatic checking of registration conditions and providing auditory cues for successful or unsuccessful registrations, thereby enabling hands-free monitoring during the measurement process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the user constantly monitors a screen for feedback on recording status and conditions, then the user can obtain visual confirmation of registration accuracy and recording quality, but the survey time increases
Solution Approach 1:
The patent implements acoustic feedback through a sound generator that provides immediate auditory confirmation of registration status and recording conditions. The system generates specific sounds to indicate successful registrations, focus quality, and other measurement parameters, allowing users to monitor the process without visual attention to a screen.
Solution Approach 2:
The patent replaces the visual feedback mechanism (screen monitoring) with an acoustic feedback mechanism (sound generator). This substitution allows users to receive measurement status information through sound rather than sight, eliminating the need to constantly watch a screen during the survey process.
2Reliability
If the user constantly monitors a screen for feedback on recording status and conditions, then the user can obtain visual confirmation of registration accuracy and recording quality, but the ease of operation decreases
Solution Approach 1:
The system provides continuous acoustic feedback about registration status, focus quality, and measurement parameters through a sound generator. This allows users to operate the dental camera hands-free while still receiving real-time information about measurement quality and registration accuracy.
Solution Approach 2:
The sound generator acts as an intermediary between the measurement system and the user, translating complex registration status and recording conditions into simple audible signals that convey essential information without requiring visual attention or complex interpretation.
3Loss of time
If acoustic feedback is generated to provide hands-free monitoring, then the survey time is reduced and ease of operation improves, but the device complexity increases
Solution Approach 1:
The patent integrates a sound generator into the existing dental camera system to replace visual monitoring requirements. This addition of acoustic feedback capability, while increasing device complexity, enables hands-free operation and reduces survey time by eliminating the need for continuous screen monitoring.

AI summary
The invention relates to a method for measuring a dental object (1) using a dental camera (2). During measurement, several optical three-dimensional images (3, 50, 51) of the object (1) are produced. During measurement, an acoustic sound (10, 12) is generated by means of a sound producer (9, 11), said sound (10, 12) being used as feedback for the user and information relating to the current status of a recording of the images (3, 50, 51) and/or relating to image requirements of the dental camera (2) are transmitted to the user. Then, each individual image (3, 50, 51) it is automatically checked by a computer (6) as to whether an overlapping area (7, 8) between the images (3, 50, 51) which are to be combined meets the defined recording requirements for a correct recording.
