Orthotic Helmet Traction Stabilization for Jaw Position Correction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing jaw position correcting apparatuses, such as headgears, suffer from displacement relative to the head when external forces are applied, leading to instability in the traction direction, particularly in children, which affects orthodontic effectiveness.
Innovation Solution
A jaw position correcting apparatus comprising an orthotic helmet with a tractor that pulls the orthotic device forward and upward, secured by elastic members, and a helmet fixing part that stabilizes the traction direction using a 3D-scanned and 3D-printed configuration tailored to the user's head shape.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a wire frame headgear with sponge pads and bands is used, then the headgear is light in weight and easily adapted to the shape of the head, but the headgear may be displaced relative to the head when external force is applied, causing instability in traction direction
Solution Approach 1:
The headgear is divided into multiple functional components: a wire frame structure for adaptability, sponge pads for comfort, and additional stabilizing elements (bands, straps, or rigid supports) that can be independently adjusted to prevent displacement while maintaining the lightweight and adaptable nature of the original design
Solution Approach 2:
The headgear combines multiple materials with different properties: the wire frame provides structural support and adaptability, sponge pads provide comfort and friction, and additional stabilizing materials (such as rigid bands or straps) are integrated to prevent displacement, creating a composite structure that achieves both adaptability and stability
2Device complexity
If a wire frame headgear is used, then the configuration is simple and lightweight, but the headgear may be caught by clothes or hit walls during play, causing constant displacement in children
Solution Approach 1:
The headgear is designed with pre-positioned stabilizing elements and adjustment mechanisms that are set up in advance to anticipate and prevent displacement before it occurs, allowing the simple wire frame structure to gain enhanced stability without requiring complex additional components
Solution Approach 2:
Additional stabilizing elements act as intermediaries between the wire frame and the head, providing extra contact points and distribution of forces that prevent displacement from external impacts or clothing entanglement, while maintaining the overall simplicity of the device
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enhances stability and suppresses displacement of the orthotic device, promoting appropriate jaw and dentition growth by maintaining a consistent traction direction.
Implementation Method 1
a first locking part provided to a front end of a forward extending part extending from an inside of the mouth to an outside of the mouth and urged upward by a first elastic member
