Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If traditional orthodontic treatment methods are used without automated alignment shape generation, then treatment can be provided, but the process is time-consuming and lacks precision in generating personalized alignment shapes

Engineering Contradiction:

Improvetreatment efficiencyVSAvoidtime for generating alignment shape

Core Design Contradiction:

ProductivityVSLoss of time

Solution Approach 1:

The patent replaces manual mechanical methods of creating orthodontic alignment shapes with an automated computer-based system. The processor automatically extracts tooth shape information from patient data, compares it with standard arch forms, and generates personalized alignment shapes without manual intervention, significantly improving treatment efficiency and reducing time loss.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent creates digital copies of patient tooth shapes by extracting specific point coordinates from patient tooth shape information. These digital models are then compared with standard arch form databases to generate alignment shapes, enabling rapid reproduction and analysis without physical model fabrication.

Inventive Principle:

Principle #26Copying

2Manufacturing precision

If manual methods are used to create orthodontic alignment shapes, then treatment can be provided, but the accuracy and personalization of the alignment shape generation is insufficient

Engineering Contradiction:

Improvealignment shape accuracyVSAvoidsystem complexity for generating alignment shape

Core Design Contradiction:

Manufacturing precisionVSDevice complexity

Solution Approach 1:

The patent replaces imprecise manual methods with an automated computer-based system that extracts tooth shape information, compares it with standard arch forms using statistical cluster analysis, and generates personalized alignment shapes with high precision.

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system automatically adapts to each patient's unique tooth arch form by extracting specific point coordinates, comparing them with the standard arch form database, and generating personalized alignment shapes. The processor independently determines the appropriate standard arch form match and creates customized treatment plans without manual intervention, achieving both personalization and operational simplicity.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent replaces manual customization processes with an automated system that handles the complexity of individualized treatment planning. The computer-based system efficiently processes patient-specific data, performs comparisons with standard arch forms, and generates personalized alignment shapes, making adaptability to individual variations practical and scalable.

Inventive Principle:
