Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If specialized equipment is used for monitoring tooth movement, then measurement precision is improved, but device complexity and cost increase
Solution Approach 1:
The patent creates a virtual 3D model that copies the patient's actual dentition, allowing monitoring of tooth movement through digital representations rather than physical measurement devices. The system captures images and generates virtual models that replicate real tooth positions, enabling accurate tracking without specialized dental equipment.
Solution Approach 2:
The patent replaces mechanical measurement equipment with a computational imaging system. Instead of using specialized dental scanners or measurement devices, the system uses standard camera imaging combined with computer vision algorithms to detect and track tooth positions, substituting mechanical systems with optical and computational approaches.
2Measurement precision
If in-person appointments are used for monitoring, then measurement precision is improved, but loss of time increases
Solution Approach 1:
The patent enables patients to perform self-monitoring by capturing images of their own teeth using their mobile devices. The system allows patients to take photos, generate 3D models, and track their own tooth movement without requiring professional intervention for each measurement, making the monitoring process self-service oriented.
Solution Approach 2:
The system performs preliminary processing of images and generates 3D models automatically without requiring patient presence at a clinic. By pre-processing the imaging data and conducting measurements remotely before any potential in-person visits, the system reduces the frequency and duration of required appointments.
3Measurement precision
If frequent in-person monitoring is conducted, then measurement precision is improved, but loss of time and productivity decrease
Solution Approach 1:
The patent replaces repeated physical clinic visits with automated remote monitoring using computational imaging. The system substitutes the mechanical process of in-person examinations with an automated image-based measurement system that can process multiple data points without requiring patient or provider time investment for each measurement.
4Manufacturing precision
If 3D scanning equipment is used, then manufacturing precision of digital model is improved, but device complexity and cost increase
Solution Approach 1:
The patent creates accurate digital copies of the dentition using standard imaging technology rather than specialized 3D scanners. By capturing multiple 2D images and computationally reconstructing a 3D model, the system produces a digital replica of the teeth with sufficient precision for orthodontic monitoring without requiring expensive scanning equipment.
Solution Approach 2:
The system uses inexpensive, widely available mobile device cameras instead of expensive, specialized 3D scanning equipment. The approach replaces costly, complex devices with cheap, ubiquitous technology that can be found in most patients' pockets, dramatically reducing the barrier to entry while maintaining adequate measurement precision.
