Pin Connector With Reduced Diameter Segment For Orthodontic Force Module
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing orthodontic force modules require high skill and trial-and-error to achieve the correct distance and play between the force module and orthodontic appliances, leading to complex and error-prone installation processes for correcting Class II and Class III malocclusions.
Innovation Solution
The development of pin connectors with a region of reduced cross-sectional diameter that preferentially bends to securely attach orthodontic force modules to buccal tubes or other appliances, providing a predetermined play of 1.5 mm to 2.5 mm, simplifying the attachment process and reducing bending errors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a bendable pin is used to attach the force module to the orthodontic appliance, then the force module can be securely attached, but the installation process requires high skill and trial-and-error to achieve the correct distance and play
Solution Approach 1:
The pin connector is pre-formed with a predetermined bend radius that creates a specific play distance (1.5mm to 2.5mm) between the force module and orthodontic appliance. This preliminary configuration eliminates the need for the orthodontist to perform trial-and-error bending during installation, while still achieving secure attachment through the engineered bend geometry.
Solution Approach 2:
The pin connector incorporates a region of reduced cross-sectional diameter that changes the physical parameters of the pin at a specific location. This reduced diameter region allows the pin to bend predictably at the desired location with the predetermined radius, transforming the installation process from a skill-intensive trial-and-error procedure to a simple insertion operation.
2Manufacturing precision
If the pin connector has a region of reduced cross-sectional diameter to enable predetermined bending, then the bending location and radius are controlled, but the pin structure becomes more complex
Solution Approach 1:
The pin connector features a localized region of reduced cross-sectional diameter at a specific position along its length. This local modification creates a hinge-like behavior at the reduced diameter region while the rest of the pin maintains its full strength and rigidity. The local quality change enables precise bending control without requiring complex overall pin结构设计.
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
The pin connectors facilitate easier and more accurate attachment of orthodontic force modules, reducing the need for skilled determination of bending locations and minimizing installation errors, thereby enhancing the efficiency and precision of orthodontic treatments for Class II and Class III malocclusions.
Implementation Method 1
The region of reduced cross-sectional diameter causes the elongate pin body to preferentially bend in the region of reduced cross-sectional diameter when attaching the pin connector to an orthodontic buccal tube or other orthodontic appliance

AI summary
A pin connector for attaching an orthodontic force module to an orthodontic appliance is configured to preferentially bend in a middle segment along an elongate pin body of the pin connector. The pin connector includes an elongate pin body and an extension rod extending laterally from an end of the pin body for interconnecting the pin body and an orthodontic force module. The elongate pin body includes first, second and third segments, with the second segment having reduced cross-sectional diameter relative to the first and third segments so that pin body preferentially bends in the second segment rather than the first and third segments when attaching the orthodontic force module to the orthodontic appliance. This provides a preselected amount of distance or play between the orthodontic force module and the orthodontic appliance.
