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

VSEngineering 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

Engineering Contradiction:
Improveregistration accuracyVSAvoidsurvey time
Core Design Contradiction:
ReliabilityVSLoss of time

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.

Inventive Principle:
Principle #23Feedback

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.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

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

Engineering Contradiction:
Improveregistration accuracyVSAvoidhands-free monitoring
Core Design Contradiction:
ReliabilityVSEase of operation

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.

Inventive Principle:
Principle #23Feedback

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.

Inventive Principle:
Principle #24Intermediary (Mediator)

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

Engineering Contradiction:
Improvesurvey timeVSAvoidsound generator integration
Core Design Contradiction:
Loss of timeVSDevice complexity

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.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

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.
