Solution Overview

Problem

Teledentistry systems face inefficiencies due to the challenge of capturing high-quality oral images without assistance, often resulting in unusable images due to improper capture of target teeth, poor clarity, lighting, or angles, which can delay treatment and increase costs.

Innovation Solution

An imaging system that uses an imager and processor to extract features from images, determining if they meet a predetermined threshold, and provides feedback to the user for physical adjustments to improve image quality, ensuring high-quality images are captured and transmitted to dental professionals.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If an individual captures oral images without assistance using a smartphone or imaging device, then accessibility and convenience are improved, but image quality and reliability deteriorate due to inability to visualize screen while capturing

Engineering Contradiction:
Improveconvenience of self-captureVSAvoidimage quality
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The system provides real-time feedback to the user during image capture by analyzing the captured image and providing guidance on how to improve image quality. The processor extracts features from the captured image and generates feedback instructions that are displayed to the user, enabling them to adjust their capture technique to achieve diagnostic-quality images without professional assistance.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system enables individuals to perform their own oral health imaging and assessment without requiring a dental professional's direct assistance. Through automated feature extraction, quality assessment, and feedback mechanisms, the system allows users to independently capture and evaluate their own oral images, making the service accessible and convenient while maintaining reliability.

Inventive Principle:
Principle #25Self-service

2Reliability

If multiple trial and error shots are taken to capture sufficient quality images, then image quality may be improved, but time consumption and productivity worsen

Engineering Contradiction:
Improveimage qualityVSAvoidtime efficiency
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

Instead of relying on multiple trial and error attempts, the system provides immediate feedback after each capture attempt, guiding the user on specific adjustments needed. This feedback mechanism reduces the number of attempts required by informing users of precise improvements needed, thereby maintaining image quality while significantly reducing time consumption.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system performs preliminary analysis of the captured image immediately upon capture, extracting features and determining quality metrics before the user needs to retake the image. This preliminary assessment allows the system to provide targeted feedback that prevents future capture errors, reducing the need for multiple attempts and improving overall efficiency.

Inventive Principle:
Principle #10Preliminary action

3Productivity

If inferior images are used for analysis or additional images are requested, then the system can continue to operate, but treatment delays and costs increase

Engineering Contradiction:
Improvesystem operation continuityVSAvoidtreatment delay
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The system performs preliminary quality assessment and feature extraction on captured images before they are used for diagnostic analysis. By evaluating image quality metrics and extracting relevant features in advance, the system ensures that only sufficient-quality images proceed to analysis, preventing treatment delays that would occur if inadequate images were submitted for review.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system provides feedback to users about image quality deficiencies and guides them to capture improved images before submission. This feedback loop prevents inferior images from reaching the analysis stage, ensuring continuous productive operation without treatment delays caused by requesting additional images or re analyzing poor-quality submissions.

Inventive Principle:
Principle #23Feedback
