Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a three-dimensional model is directly modeled based on a planar image of a target object, then the modeling process is simple, but the quality of the three-dimensional model is poor with low restoration degree
Solution Approach 1:
The patent transitions from two-dimensional planar images to three-dimensional modeling by introducing depth information as a new dimension. Multiple planar images from different perspectives are processed to extract depth data, which is then integrated to reconstruct the three-dimensional object, thereby resolving the contradiction between simple modeling processes and high model quality.
Solution Approach 2:
The patent segments the modeling process into distinct stages: obtaining multiple planar images from different perspectives, extracting boundary information, predicting depth information, and finally generating the three-dimensional model. This segmentation allows each stage to be optimized independently, improving overall model quality while maintaining process manageability.
2Manufacturing precision
If multiple planar images from different perspectives are obtained and processed to improve model quality, then the restoration degree improves, but the device complexity and processing steps increase
Solution Approach 1:
The patent introduces boundary information and depth information as intermediary elements that mediate between the input planar images and the final three-dimensional model. These intermediaries simplify the complex transformation process by providing structured representations that bridge the gap between 2D images and 3D reconstruction, making the overall process more manageable despite the increased number of processing steps.
3Manufacturing precision
If depth information is predicted and boundary information is extracted to enhance model accuracy, then the three-dimensional model quality improves, but the processing time and computational resources increase
Solution Approach 1:
The patent performs preliminary actions by extracting boundary information and predicting depth information from multiple planar images before generating the final three-dimensional model. These preliminary processing steps prepare the data in advance, allowing the main modeling process to proceed more efficiently and reducing overall processing time despite the additional computational requirements for accurate depth and boundary extraction.
