Engineering Contradiction Analysis
1Manufacturing precision
If traditional hardware devices (camera rigs, laser scanners, articulated arms) are used for 3D modeling, then measurement precision and manufacturing precision are improved, but device complexity and ease of operation deteriorate due to cumbersome equipment and manual editing requirements
Solution Approach 1:
The patent replaces complex mechanical 3D scanning hardware (camera rigs, laser scanners, articulated arms) with a mobile device-based system that uses camera imaging combined with virtual point selection and computational processing to generate 3D models. This substitution maintains acceptable modeling precision while dramatically improving ease of operation.
Solution Approach 2:
The system creates a digital copy of the physical object through photogrammetry techniques, capturing multiple 2D images and reconstructing a 3D model through computational algorithms. This copying approach eliminates the need for direct physical measurement hardware while achieving accurate 3D representations.
2Manufacturing precision
If traditional manual editing processes are used for 3D model data, then manufacturing precision is maintained through professional editing, but productivity and loss of time increase due to time-consuming manual editing for each model
Solution Approach 1:
The system enables end users to directly create and edit 3D models themselves through intuitive virtual point selection on mobile device screens, eliminating the need for specialized 3D artists and manual editing processes. This self-service approach maintains sufficient model quality for various applications while dramatically increasing productivity.
Solution Approach 2:
The patent employs accelerated computational processing and automated algorithms to rapidly process captured images and generate 3D models, significantly reducing the time required compared to traditional manual editing while maintaining acceptable quality standards.
3Measurement precision
If extensive hardware equipment is used for 3D modeling, then measurement precision is improved, but device complexity and cost increase
Solution Approach 1:
The patent utilizes a mobile device camera, which is a universal multi-functional device already present in most smartphones and tablets, to perform 3D scanning functions. This eliminates the need for specialized dedicated scanning hardware while achieving sufficient measurement precision for various applications.
Solution Approach 2:
The system replaces expensive, complex, and fragile specialized scanning hardware with inexpensive, readily available mobile device cameras. This substitution reduces both equipment cost and complexity while maintaining acceptable measurement capabilities for many practical applications.
