Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If manual methods are used to create physical dental arch models, then flexibility and adaptability are maintained, but manufacturing precision and consistency deteriorate due to human limitations in visualizing and manipulating three-dimensional structures
Solution Approach 1:
The patent uses digital 3D models as copies of the physical tooth models. The digital base model is generated from digital tooth models and used to create the physical base through CNC machining. This copying approach allows precise reproduction of tooth positions and orientations without requiring complex manual manipulation, resolving the contradiction between precision and system complexity.
Solution Approach 2:
The patent replaces manual mechanical manipulation with CNC (Computer Numerical Control) machining. Instead of manually positioning and assembling tooth models, the system uses programmed CNC operations to automatically create the base with precise features, eliminating human limitations in visualizing and manipulating 3D structures while maintaining manufacturing precision.
2Adaptability or versatility
If multiple wire changes are made during orthodontic treatment, then treatment adaptability is improved, but patient discomfort and treatment cost increase
Solution Approach 1:
The patent creates physical dental arch models before the actual orthodontic treatment begins. These pre-fabricated models with accurately positioned tooth models allow the orthodontist to plan and visualize the entire treatment sequence in advance, enabling better adaptability to different treatment scenarios without requiring multiple wire changes during the treatment process, thus reducing treatment time and patient discomfort.
3Measurement precision
If human experts manually place brackets and wire, then diagnostic expertise is utilized, but measurement precision and estimation accuracy deteriorate due to limitations in human sight and manual skill
Solution Approach 1:
The patent creates digital copies of the patient's teeth and desired orthodontic structure. These digital models allow precise measurement and estimation of wire bends and bracket positions without the limitations of human sight and manual skill. The digital base model can be accurately generated from digital tooth models, providing precise measurement capabilities while maintaining ease of operation through automated CNC manufacturing.
