Solution Overview

Problem

Conventional orthodontic devices are complex and difficult to customize for individual tooth alignment, making it challenging to apply precise force adjustments, which complicates their use and manufacturing.

Innovation Solution

The orthodontic device features an inner and outer housing with adjustable brackets and a pressing force mechanism, allowing for customizable alignment and force application on each tooth, using a screw, stopper, and compression spring system, along with zirconia for enhanced grip and surface roughness to prevent slipping.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If conventional orthodontic devices are used to correct teeth, then the entire teeth are corrected in a certain direction, but it is difficult to individually correct the teeth in different directions

Engineering Contradiction:
Improveindividual tooth correction capabilityVSAvoiddevice structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The orthodontic device divides the correction mechanism into individual brackets for each tooth, allowing independent adjustment of force direction and magnitude for each tooth while maintaining a unified overall structure

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The bracket design incorporates multiple functional elements including pressing portions, engaging portions, and adjusting mechanisms that can perform multiple correction functions within a single component, enabling individual tooth correction without requiring separate devices for each tooth

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

2Manufacturing precision

If the force applied to each tooth is adjusted individually, then proper correction of each tooth is achieved, but the orthodontic device becomes complicated

Engineering Contradiction:
Improveforce application precisionVSAvoidadjustment mechanism
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The bracket includes an adjusting mechanism with movable pressing portions that can be positioned at different locations along the bracket body, allowing dynamic adjustment of force magnitude and direction for each tooth based on individual correction needs

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The device incorporates self-adjusting features where the bracket structure itself provides the adjustment capability through movable pressing portions and engaging portions that can be repositioned without requiring complex external adjustment mechanisms

Inventive Principle:
Principle #25Self-service

3Measurement precision

If the orthodontic device has a complicated mechanism for individual tooth correction, then high accuracy correction is achieved, but the usage method becomes complicated and difficult to handle for patients

Engineering Contradiction:
Improvetooth alignment accuracyVSAvoidpatient usability
Core Design Contradiction:
Measurement precisionVSEase of operation

Solution Approach 1:

The bracket design allows patients to perform adjustments themselves through user-friendly engaging portions and movable pressing portions that can be repositioned by patients without requiring professional intervention, maintaining high precision while improving ease of operation

Inventive Principle:
Principle #25Self-service
