Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If specialized hardware (multiple image capture devices, structured light sources, laser solutions) is used to capture anatomical data, then measurement precision and 3D model accuracy are improved, but device complexity and cost increase
Solution Approach 1:
The patent applies universality by enabling a single mobile camera to perform multiple functions: capturing 2D images, estimating depth information, and generating 3D anatomical models. This eliminates the need for specialized multi-device hardware systems while achieving comparable measurement precision through software-based processing of standard camera images.
Solution Approach 2:
The patent creates virtual 3D copies of anatomical structures from 2D camera images through image processing and depth estimation algorithms. These digital 3D models serve as accurate representations of physical anatomy, enabling precise measurements without requiring physical 3D scanning hardware.
2Manufacturing precision
If specialized hardware systems are deployed for 3D scanning, then manufacturing precision of fitted products is improved, but ease of operation and accessibility deteriorate
Solution Approach 1:
The patent enables users to perform their own anatomical scanning using personal mobile devices without requiring specialized hardware operators or complex setup procedures. The system automatically processes images and generates 3D models, allowing end-users to independently obtain precise anatomical data for product fitting purposes.
Solution Approach 2:
The patent replaces complex mechanical 3D scanning hardware with software-based image processing algorithms that run on standard mobile cameras. This substitution maintains manufacturing precision for product fitting while dramatically improving ease of operation by using ubiquitous consumer devices instead of specialized equipment.
3Measurement precision
If multiple image capture devices and structured light sources are used, then depth measurement accuracy is improved, but loss of time for setup and operation increases
Solution Approach 1:
The patent performs preliminary depth estimation and 3D model generation directly on the mobile device using onboard processing capabilities. By pre-computing depth information from captured images before transmission or further processing, the system reduces overall processing time and eliminates the need for complex real-time hardware coordination during the scanning process.
