Engineering Contradiction Analysis
1Area of stationary object
If three-dimensional models are projected onto real-world structures using conventional projection equipment, then the display area is increased, but distortion and loss of detail occur during transformation from three-dimensional to two-dimensional representations
Solution Approach 1:
The patent applies dimensionality change by generating a three-dimensional reflection model from the original three-dimensional object model, then transforming this intermediate representation into a two-dimensional projection for display on the real-world structure. This intermediate three-dimensional reflection model preserves spatial relationships and enables accurate mapping onto the structure's surface, resolving the distortion problem while maintaining large display area.
Solution Approach 2:
The three-dimensional reflection model serves as an intermediary between the original object model and the final two-dimensional projection. This intermediary representation captures the essential geometric and visual properties of the object while adapting them to the specific geometry of the real-world structure, thereby maintaining projection accuracy across large display areas.
2Device complexity
If conventional projection methods are used to display three-dimensional models, then the device complexity is reduced, but rendering errors and artifacts increase
Solution Approach 1:
By introducing the three-dimensional reflection model as an intermediate representation, the system achieves higher projection quality through a systematic transformation process. The three-dimensional reflection model captures accurate spatial relationships and can be precisely mapped to the real-world structure, reducing rendering errors and artifacts compared to direct two-dimensional projection methods.
3Adaptability or versatility
If three-dimensional models are transformed to two-dimensional representations for projection, then the display is adapted to real-world structures, but distortion and loss of detail occur
Solution Approach 1:
The patent uses a three-dimensional reflection model as an intermediate step that preserves the spatial and geometric information of the original object. This three-dimensional intermediate representation can then be accurately mapped onto the real-world structure's surface, maintaining detail and reducing distortion while achieving adaptability to various structural geometries.
Solution Approach 2:
The three-dimensional reflection model acts as an intermediary that bridges the original object model and the real-world structure. It captures and preserves essential geometric details and spatial relationships, enabling accurate projection onto structures with complex geometries without significant loss of information or detail.
