Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If existing 2D image/video compression standards are used, then compression efficiency is improved, but 3D spatial information is lost
Solution Approach 1:
The patent extends 2D image data by adding 3D spatial information dimensions. It encodes not only the 2D image pixels but also associated 3D position, orientation, and depth data, transforming flat 2D compression into 3D-aware compression that preserves spatial relationships while maintaining efficiency.
Solution Approach 2:
The patent nests 3D spatial information within the 2D image data structure. The 3D metadata is embedded alongside the 2D image pixels in a unified data container, allowing both 2D visual information and 3D spatial context to be transmitted together without requiring separate data streams.
2Adaptability or versatility
If 2D data is input to 3D media tools, then 3D rendering capability is improved, but separate processing is required
Solution Approach 1:
The patent performs preliminary encoding of 3D spatial information along with the 2D image data during the compression stage. By pre-attaching 3D metadata to 2D images before transmission or storage, the system eliminates the need for separate post-processing steps when the data is later rendered in 3D media tools.
Solution Approach 2:
The patent creates a universal data format that serves both 2D viewing and 3D rendering purposes. The same encoded data structure can be directly interpreted by 3D media tools without conversion, making the system adaptable to both 2D and 3D applications from a single data source.
3Productivity
If 2D data is directly rendered in 3D space, then real-time rendering is improved, but data structure complexity increases
Solution Approach 1:
The patent segments the data structure into distinct but integrated components: 2D image pixels and 3D spatial metadata. This segmentation allows the rendering system to process 2D and 3D information independently where needed while maintaining their relationship, improving real-time rendering performance by avoiding the complexity of fully 3D data formats.
