Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a three-dimensional scanner is used to obtain 3D information, then measurement precision is improved, but device complexity increases and ease of operation deteriorates
Solution Approach 1:
The patent combines multiple camera systems (color camera, depth camera, infrared camera) and multiple functions (scanning, modeling, animation) into a single mobile terminal device. This integration allows common users to access 3D scanning capabilities without needing separate professional equipment, thereby improving ease of operation while maintaining measurement precision through the coordinated use of multiple sensors.
Solution Approach 2:
The mobile terminal is designed to perform multiple functions beyond traditional 3D scanning, including panoramic scanning, 3D model reconstruction, skeletal model fusion, and animation generation. This multi-functionality allows a single device to serve both professional and consumer needs, making 3D technology accessible to common users while preserving measurement accuracy through specialized camera systems.
2Manufacturing precision
If a three-dimensional scanner is used to create accurate 3D models, then manufacturing precision is improved, but device complexity increases
Solution Approach 1:
The patent merges multiple camera systems (color camera for texture, depth camera for geometry, infrared camera for additional depth information) into a single mobile terminal. This consolidation achieves accurate 3D modeling through coordinated multi-sensor data fusion while reducing device complexity compared to using separate professional scanning equipment.
Solution Approach 2:
The patent introduces a skeletal model as an intermediary structure that simplifies the representation of complex 3D objects. By fusing the skeletal model with detailed 3D scan data, the system achieves manufacturing precision for both the overall structure and fine details, while the skeletal abstraction reduces computational complexity.
3Measurement precision
If professional three-dimensional scanning equipment is used, then measurement precision is improved, but ease of operation deteriorates and adaptability decreases
Solution Approach 1:
The mobile terminal is designed to adapt to multiple application scenarios beyond traditional 3D scanning, including panoramic scanning, virtual try-on, augmented reality, and animation creation. The device maintains measurement precision through specialized camera systems while achieving versatility through software-based processing and multiple camera configurations.
Solution Approach 2:
The patent implements dynamic scanning capabilities that can adapt to different object types and scanning scenarios. The system can switch between different camera combinations and processing modes based on the scanning target, enabling both high-precision scanning of static objects and dynamic tracking of moving objects, thereby improving adaptability while maintaining accuracy.
