Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If three-dimensional shapes are used for calculating display mode, then the display reality and texture are improved, but the data quantity and processing load increase significantly
Solution Approach 1:
The patent uses two-dimensional images as simplified copies of three-dimensional objects, capturing only the essential visual information needed for display mode calculation. This approach maintains display reality while significantly reducing data quantity and processing complexity compared to using full three-dimensional shapes.
Solution Approach 2:
The patent extracts only the necessary visual features from three-dimensional objects by using two-dimensional images. This extraction process removes unnecessary geometric data while preserving the key information needed for calculating display modes, thereby reducing processing load without sacrificing display quality.
2Manufacturing precision
If three-dimensional shapes are used for calculating display mode, then the display texture is improved, but the responsiveness to observer motion deteriorates
Solution Approach 1:
By using two-dimensional images as simplified representations, the system can rapidly process and update display modes in response to observer motion. This copying approach maintains visual quality while enabling faster computational performance compared to processing full three-dimensional shapes.
Solution Approach 2:
The patent implements dynamic adjustment of display modes based on real-time observer position data. The two-dimensional image approach allows for rapid recalculation and updating of display parameters as the observer moves, ensuring responsive adaptation without the computational burden of three-dimensional processing.
3Manufacturing precision
If three-dimensional shapes are used, then the visual reality is improved, but the memory requirements increase
Solution Approach 1:
The patent stores and processes two-dimensional images as simplified copies of three-dimensional objects. This approach maintains the visual information necessary for realistic display while occupying significantly less memory space compared to storing complete three-dimensional geometric data structures.
Solution Approach 2:
The patent extracts only the essential visual information from three-dimensional objects by using two-dimensional images. This extraction eliminates redundant geometric data, thereby reducing memory requirements while preserving the key visual characteristics needed for realistic display rendering.

AI summary
In an information display apparatus and method, images of a plurality of planar objects disposed in a virtual space are generated based on texture information of each of the objects, viewpoint information, and surrounding environment information, and combined to generate a display image. The virtual space is a simulation of a space in which a display device is placed, the objects are disposed in parallel with a plane in the virtual space corresponding to a display screen of the display device. The texture can be expressed with a small quantity of data and a small memory size, and an image which has a good reality can be displayed with a good responsiveness to the motion of the observer.
