Orthodontic Wire Guide Plate Structure to Prevent Z-Axis Bending
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wire processing apparatuses fail to adequately prevent z-axis bending of orthodontic wires due to exposed spaces that allow unintended bending, compromising quality and efficiency.
Innovation Solution
The apparatus incorporates a pair of guide plates spaced apart in the z-axis direction with a bracket and bush configuration, minimizing wire exposure by constraining the wire within a slit and using an eccentrically located pin to bend the wire along the x-axis and y-axis planes, reducing z-axis bending.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a conventional wire bending apparatus is used with exposed wire space, then the apparatus structure is simple and easy to manufacture, but z-axis bending cannot be prevented and manufacturing precision deteriorates
Solution Approach 1:
The wire path is divided into multiple constrained segments: the wire passes through a bush, then through a slit in the bracket, and finally through a slit in the guide plate. Each segment provides localized constraint in the z-axis direction, preventing unwanted bending while maintaining overall structural simplicity
Solution Approach 2:
Guide plates and slits are introduced as intermediary structures between the wire feeding device and the bending pin. These intermediaries constrain the wire's movement in the z-axis direction without interfering with the bending operation, solving the precision problem while adding minimal structural complexity
2Manufacturing precision
If wire exposure is minimized by constraining wire within guide plates and bracket, then z-axis bending is prevented, but device complexity increases
Solution Approach 1:
The guide plates are integrated with the bracket structure, and the slits are formed directly in these components rather than being separate parts. This merging of functions reduces the number of discrete components while maintaining the wire constraint capability, thus limiting the increase in device complexity
Solution Approach 2:
The guide plates serve multiple functions: they constrain the wire in the z-axis direction, guide the wire through the bending zone, and provide structural support for the bending pin assembly. This multi-functionality reduces the need for additional specialized components
