Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional in vitro simulated brackets with standardized dentition are used for training, then the training system is simple and easy to operate, but it cannot prepare trainees for complex clinical situations or individualized malocclusion
Solution Approach 1:
The patent uses 3D scanning to create digital copies of actual patient dentition and 3D printing to produce physical training models that replicate complex clinical scenarios. This allows trainees to practice on accurate replicas of real patient cases without requiring the actual patients present, thereby improving adaptability while maintaining training system accessibility
Solution Approach 2:
The system performs preliminary 3D scanning and digital modeling of patient dentition before training begins. This pre-preparation creates customized training materials that reflect actual clinical complexity, allowing trainees to encounter realistic scenarios in advance without adding complexity to the training process itself
2Measurement precision
If thorough evaluation of distinctly shaped teeth from multiple directions is performed, then evaluation accuracy is improved, but the process becomes time-consuming and difficult to accomplish due to limited trainers
Solution Approach 1:
The patent introduces a digital 3D evaluation dimension that allows comprehensive assessment of bracket bonding from multiple angles and perspectives simultaneously. The digital model can be rotated and viewed from any direction, providing thorough evaluation accuracy without the time constraints of physical manual inspection by limited trainers
Solution Approach 2:
The system uses digital imaging technology and software as an intermediary between the physical training model and the evaluation process. This intermediary captures and preserves evaluation data objectively, allowing multiple trainers to assess the same case simultaneously without interfering with each other or extending the evaluation time
3Ease of operation
If evaluation relies on trainer's experience with naked eyes or scales, then the evaluation process is simple, but the reproducibility of the evaluation is doubtful
Solution Approach 1:
The system incorporates digital imaging and measurement tools that provide objective feedback on bracket positioning and bonding quality. This feedback is captured in quantifiable data that can be consistently analyzed across different trainers and sessions, maintaining ease of operation while significantly improving reproducibility through standardized measurement criteria
Solution Approach 2:
The patent replaces the mechanical/subjective evaluation method (trainer's naked eye and manual scales) with digital imaging and computational analysis systems. This substitution maintains the simplicity of the evaluation process while eliminating human variability, thereby ensuring consistent and reproducible results across different trainers and time points
Data Source
AI summary
A training method for evaluating the bonding accuracy of orthodontic brackets is provided. The evaluation method includes a training device for racket bonding accuracy evaluation which includes virtual teeth with root-shaped connectors and an evaluation base to fix the virtual teeth. Multiple reference lines are marked on the evaluation base, and their intersection is set as the evaluation point. When the virtual tooth is fixed to the evaluation base, the reference lines and the evaluation points are utilized for rapid evaluation of the bonding accuracy of the bracket. Moreover, thanks to their horizontal arrangement, when there are multiple virtual teeth, the evaluation of bracket bonding would be more intuitive and efficient than using the traditional articulator.
