Solution Overview

Problem

Existing orthodontic devices fail to effectively harmonize skull-facial skeletal structures, correct dysmetria, and re-educate swallowing habits, leading to inadequate treatment of malocclusions and related skeletal issues, particularly due to limitations in design that do not account for individual anatomy and the role of the tongue in dental arch morphology.

Innovation Solution

An orthodontic elastic harmonizer device with elastically deformable occlusal bimaxillary guides, vestibular and lingual-palatal flanges that provide proprioceptive stimulation, and a steep inclined plane to guide the tongue into correct posture, ensuring proper alignment and repositioning of teeth and jaw, while accommodating various facial shapes and skeletal classes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If conventional orthodontic devices are used, then basic tooth alignment may be achieved, but skull-facial skeletal structures remain unharmonized and dysmetria persists

Engineering Contradiction:
Improvetooth alignment precisionVSAvoidskull-facial structure harmonization
Core Design Contradiction:
Manufacturing precisionVSAdaptability or versatility

Solution Approach 1:

The orthodontic device integrates multiple functions into a single apparatus: it provides tooth alignment through archwires, harmonizes skull-facial skeletal structures through specifically designed flanges that apply controlled forces to bone, and addresses dysmetria through adjustable components. This multi-functional design allows the device to simultaneously treat dental and skeletal issues that conventional single-function devices cannot address.

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

Solution Approach 2:

The device employs different structural components with specialized functions: vestibular flanges for external cheek support and skeletal guidance, lingual-palatal flanges for internal tongue and palate support, and differentiated archwires for specific tooth groups. Each component is designed with local quality characteristics tailored to its specific anatomical location and therapeutic purpose, enabling precise control over different regions of the oral and facial structures.

Inventive Principle:
Principle #3Local quality

2Manufacturing precision

If standard orthodontic appliances are applied, then dental arch alignment may be improved, but tongue posture and swallowing habits are not re-educated

Engineering Contradiction:
Improvedental arch alignmentVSAvoidswallowing re-education
Core Design Contradiction:
Manufacturing precisionVSEase of operation

Solution Approach 1:

The lingual-palatal flanges are designed to automatically guide the tongue into the correct resting position against the palate during swallowing. The flanges create natural anatomical landmarks and pressure points that trigger the tongue to adopt the proper posture without requiring active patient intervention or complex mechanical mechanisms. The device leverages the patient's own swallowing reflex to achieve re-education.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The lingual-palatal flanges act as intermediaries between the orthodontic appliance and the tongue-musculature system. These flanges transmit controlled forces and positional guidance to the tongue, mediating the interaction between the rigid appliance and the soft, dynamic tongue tissue. This intermediary structure enables gentle, continuous guidance of tongue posture during natural swallowing movements.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Strength

If rigid orthodontic devices are used, then structural support is provided, but trauma risk increases and comfort decreases

Engineering Contradiction:
Improvestructural supportVSAvoidtrauma risk
Core Design Contradiction:
StrengthVSObject-affected harmful factors

Solution Approach 1:

The device incorporates flexible lingual-palatal flanges made from elastomeric or thermoplastic materials that can deform elastically under tongue pressure and swallowing forces. These flexible components maintain continuous contact with the tongue and palate surfaces, providing structural support while accommodating natural tissue movements without causing trauma. The flexibility allows the device to conform to individual anatomical variations while maintaining therapeutic effectiveness.

Inventive Principle:
Principle #30Flexible shells and thin films
