Orthodontic Bracket Frangible Hinge Merging Base Cover
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing orthodontic brackets are complex and costly due to separate components that require assembly, and they lack a simple mechanism for securely closing over archwires of varying sizes.
Innovation Solution
A one-piece orthodontic bracket with an integrally formed base and cover, featuring a frangible hinge mechanism that allows for easy assembly and secure closure over archwires, utilizing a single material like metal, plastic, or ceramic, with locking recesses for different archwire sizes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate cover plate and base components are used, then secure archwire fixation is achieved, but device complexity and manufacturing cost increase
Solution Approach 1:
The patent combines the base and cover plate into a single integral bracket component, eliminating the need for separate parts and assembly operations. The unified structure maintains archwire fixation security through integrated features while reducing device complexity and manufacturing cost.
Solution Approach 2:
The single-piece bracket design performs multiple functions: it serves as both the base structure and the cover mechanism, eliminating the need for separate components. The integral design provides both structural support and archwire retention features within one element.
2Reliability
If separate components are used, then secure assembly is achieved, but ease of manufacture decreases
Solution Approach 1:
By merging the base and cover into a single molded or machined component, the patent eliminates assembly operations while maintaining structural integrity. The integral design is manufactured as one piece through processes like injection molding or CNC machining, significantly simplifying production.
3Ease of operation
If frangible hinge mechanism is added, then ease of operation for closing cover is improved, but device complexity increases
Solution Approach 1:
The frangible hinge is pre-designed into the integral bracket structure during manufacturing. The predetermined fracture plane is built into the hinge region, allowing the cover to snap open or close easily without requiring complex active mechanisms. The frangible feature is a passive, pre-configured element rather than an active mechanism.

AI summary
An orthodontic bracket is provided that includes a cover and a base, wherein the cover can be rotated over an arch wire slot in the base portion. The present bracket invention operates to close when a frangible portion is severed upon initiating rotation of the cover, such that the cover rotates about a hinge, which may include a pin or axle. In one embodiment of the invention, the pin or axle can be moved laterally and/or vertically after the frangible portion is severed. Preferably, the bracket is manufactured to form one piece, such as using an injection molding, machining, or casting process. The bracket offers economical advantages because additional subsequent assembly is not required to attach a cover to a base.
