Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If physical models of dental arches are used for simulation, then manufacturing precision and reliability are improved, but device complexity and ease of operation deteriorate
Solution Approach 1:
The patent uses 2D photographs as simplified copies of dental arches instead of requiring complex 3D physical models. The neural network processes these 2D images to generate simulated views, eliminating the need for physical model fabrication while maintaining simulation capability. This copying approach resolves the contradiction by using a simpler representation that is easier to obtain and process.
Solution Approach 2:
The patent replaces the mechanical system of physical model creation, handling, and manipulation with an automated digital processing system. The neural network automatically processes 2D photographs to generate simulated dental views, eliminating manual model fabrication and manipulation steps. This substitution improves ease of operation while maintaining simulation accuracy.

Solution Approach 2:
The patent transforms the input data format from complex 3D physical models to simple 2D photographs, changing the parameter representation. The neural network learns to interpret 2D image parameters and generate accurate simulations by training on paired 2D photographs and corresponding 3D model views. This parameter transformation enables accessibility while maintaining precision through intelligent algorithmic processing.

AI summary
Disclosed is a method for generating an image of a dental arch of a beneficiary, referred to as a "modified image", the method comprising the following steps: • a) at an acquisition instant, acquiring a photograph representing the dental arch, referred to as the "original image"; • b) processing the original image such that it represents a contour of the dental arch; • c) submitting the original image to a neural network, referred to as a "simulation neural network", trained to simulate, on the original image, the effect of a dental event, in order to obtain the modified image; • d) preferably, processing the modified image in order to make it hyperrealistic; • e) preferably, • - presenting the modified image; and/or • - selecting an orthodontic apparatus depending on the modified image.
