Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional self-locking structures with complex elastic members are used, then the arch wire can be kept in the bracket, but the manufacturing difficulty increases and defect rate increases
Solution Approach 1:
The bracket is divided into separate functional components: a bracket body, a sliding cover, and a simplified elastic member. This segmentation allows each component to be manufactured independently with simpler processes, reducing overall manufacturing difficulty while maintaining self-locking functionality through the coordinated action of these modular parts.
Solution Approach 2:
The patent extracts and eliminates the complex elastic member design from traditional self-locking brackets. By removing this problematic component and replacing it with a simpler elastic member that works in conjunction with the sliding cover, the patent reduces manufacturing complexity and defect rates while preserving the essential self-locking function.
2Stability of the object's composition
If traditional four abduction ligature wings are used, then the bracket can maintain its structure, but sharp parts are formed causing oral discomfort
Solution Approach 1:
The patent applies curvature by replacing the traditional sharp-edged abduction ligature wings with a rounded wing structure. The wings are designed with curved surfaces that eliminate sharp parts, thereby reducing oral discomfort and improving patient comfort while maintaining the structural stability needed for bracket function.
3Strength
If traditional self-locking brackets with sharp shapes are used, then the bracket can resist food impact, but the sharp shape increases impact on teeth and causes wing breakage
Solution Approach 1:
The patent uses curved, rounded wing structures instead of sharp geometric shapes. This curvature distributes food impact forces more evenly across the bracket surface, preventing concentrated stress points that cause wing breakage and reducing direct impact on teeth, thereby maintaining bracket strength while eliminating harmful effects.
Solution Approach 2:
The patent merges the structural support function with the protective function by designing the rounded wings to serve both as structural elements maintaining bracket integrity and as protective features that deflect food impact away from teeth and fragile bracket components.
