Orthodontic Bracket With Adjustable Pressing Force
Find Innovative SolutionsGenerate Solutions
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
Engineering 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
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
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
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
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
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
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
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

AI summary
[Problem to be Solved] To provide an orthodontic device capable of easily manufacturing according to different dentition conditions for each patient. [Solution to Problem] Since an orthodontic device comprises an inner housing 5 covering teeth, an outer housing 3 covering the inner housing 5, a bracket 8 capable of pressing against the teeth and penetrating the inner housing 5, and a pressing force adjusting mechanism capable of adjusting a pressing force of the bracket 8 on the teeth, a dentist or a dental technician is capable of easily manufacturing the orthodontic device according to the different dentition conditions for each patient, patients are capable of easily adjusting their own teeth by the orthodontic device.
