Wire Bending Guide Plate Structure for Z-Axis Constraint
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wire processing apparatuses struggle with z-axis bending due to structural gaps that allow partial bending in this direction, compromising the precision and quality of orthodontic wire formation.
Innovation Solution
The apparatus incorporates a pair of guide plates spaced apart in the z-axis direction, a bracket with a slit, and a pin that rotates eccentrically on a rotating body, minimizing wire exposure and constraining bending to the x-y plane.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a pin rotates to bend the wire through the rotation of the pin, then bending can be applied to the wire, but the wire is also bent in the z-axis due to the twisted shape of the wire
Solution Approach 1:
A guide plate is introduced as an intermediary component between the wire feeding device and the bending pin. The guide plate includes a guide hole that constrains the wire's movement path, preventing z-axis displacement while allowing the bending pin to rotate and bend the wire in the desired x-y plane direction.
Solution Approach 2:
The solution adds a spatial dimension constraint by introducing the guide plate structure that limits wire movement to a specific plane. The guide hole's positioning and orientation create a two-dimensional constraint that eliminates unwanted three-dimensional (z-axis) movement, thereby controlling bending to occur only in the intended plane.
2Ease of operation
If the wire is fed through a gap between the base and glass panel, then the wire can be moved for bending, but bending in the z-axis direction cannot be fully restricted
Solution Approach 1:
The guide plate serves as an intermediary structure that replaces the simple gap-based wire feeding method. The guide hole in the guide plate provides a defined pathway for the wire, maintaining ease of wire feeding while adding the necessary constraint to prevent z-axis bending that the gap alone could not provide.
3Device complexity
If there is a space exposed to the outside between the base and bush, then the wire feeding structure is simple, but the wire is not constrained in the z-axis direction in this space
Solution Approach 1:
The guide plate is positioned as an intermediary component between the base and the bush, filling the exposed space and providing the necessary z-axis constraint. This addition maintains relative structural simplicity while effectively constraining the wire in the previously unconstrained exposed space.
