Solution Overview

Problem

Current dental care systems are inadequate for remote treatment, particularly during emergencies, pandemics, or physical inaccessibility, requiring physical consultations for assessments, diagnoses, and treatment plans, and lack efficient data processing and practitioner access.

Innovation Solution

A virtual dental care system utilizing intelligent photo guidance and image-based assessments to capture and analyze dental conditions remotely, providing image-based assessments, patient guidance, and treatment planning through a network of computing devices.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If physical consultations are required for dental assessments and diagnoses, then measurement precision and reliability are improved, but ease of operation and accessibility deteriorate

Engineering Contradiction:
Improvedental assessment accuracyVSAvoidpatient accessibility
Core Design Contradiction:
Measurement precisionVSEase of operation

Solution Approach 1:

The patent creates digital copies of physical dental examinations through photographs and video recordings. The image capture device records dental conditions, and the processing system analyzes these digital copies to provide assessments and diagnoses remotely, eliminating the need for physical patient-dentist contact while maintaining diagnostic accuracy.

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The patent replaces the mechanical system of physical examination with an automated image analysis system. The processing system uses computer vision algorithms to analyze captured images, substitute human visual inspection, and provide diagnostic recommendations, thereby enabling remote dental care without sacrificing measurement precision.

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

2Measurement precision

If comprehensive patient data is collected and stored, then measurement precision and treatment planning are improved, but computing resources and storage requirements increase

Engineering Contradiction:
Improvetreatment planning accuracyVSAvoidcomputing resource consumption
Core Design Contradiction:
Measurement precisionVSUse of energy by moving object

Solution Approach 1:

The patent extracts and processes only the most relevant features from captured dental images using the processing system. Rather than storing and analyzing all raw image data, the system identifies and processes key diagnostic features, reducing computing resource requirements while maintaining treatment planning accuracy.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent implements partial processing by analyzing only the essential dental features needed for diagnosis and treatment planning, rather than performing exhaustive analysis of all image data. This selective approach reduces computing resource consumption while sufficient for accurate treatment planning.

Inventive Principle:
Principle #16Partial or excessive action

3Adaptability or versatility

If multiple practitioners can access patient data, then adaptability and treatment options are improved, but data security and system complexity increase

Engineering Contradiction:
Improvepractitioner accessVSAvoidsystem architecture
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent creates a universal platform that allows multiple practitioners to access and analyze patient dental data through the same image capture and processing system. The system is designed to serve multiple users with different roles while maintaining consistent diagnostic capabilities, thereby improving adaptability without proportionally increasing complexity.

Inventive Principle:
Principle #6Universality (Multi-functionality)
