Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If binocular parallax is used to generate 3D scenes, then depth perception is improved, but device complexity increases due to requirement of specialized display devices or wearable equipment
Solution Approach 1:
The patent creates a virtual copy of the 3D scene that can be viewed on conventional 2D displays. Instead of requiring specialized hardware, the system generates a computational model of the 3D environment that renders depth cues through software algorithms, allowing users to experience 3D effects on standard displays without additional equipment.
Solution Approach 2:
The patent replaces the mechanical/optical system of specialized 3D displays with a software-based rendering system. By substituting physical 3D display mechanisms with computational geometry and projection algorithms, the system achieves 3D visualization on conventional displays without requiring autostereoscopic screens or wearable devices.
2Measurement precision
If depth mapping and parallax mapping are used to convert 2D source material into 3D images, then stereoscopic effect is improved, but interactivity with user-specified sources deteriorates
Solution Approach 1:
The patent implements a dynamic system that adapts to user-specified 2D sources in real-time. Rather than using static pre-drawn 3D content, the system continuously processes user-provided images, dynamically generates corresponding depth maps, and updates the 3D scene representation, enabling interactive customization of 3D scenes from user inputs.
Solution Approach 2:
The patent incorporates feedback mechanisms where the system analyzes user-specified 2D sources, generates depth information, renders the 3D scene, and allows users to interact with and modify the scene. This closed-loop process enables users to specify their own source material and receive customized 3D representations, enhancing adaptability and interactivity.
3Measurement precision
If pre-drawn 3D content is presented to achieve stereoscopic effect, then depth illusion is improved, but ability to dynamically customize user-specified sources deteriorates
Solution Approach 1:
The patent performs preliminary depth map generation and 3D mesh creation from user-specified 2D sources before rendering the final 3D scene. By pre-processing the user input to extract depth information and construct 3D geometry, the system prepares customized 3D content ready for interactive rendering, enabling both depth illusion and customization capability.
Solution Approach 2:
The patent transforms user-specified 2D images into 3D representations by changing key parameters including depth values, spatial coordinates, and geometric properties. Through parameter transformation algorithms, the system converts flat 2D source material into multi-dimensional 3D scenes with adjustable depth parameters, enabling dynamic customization while maintaining depth illusion.

AI summary
A computer-implemented method for generating a 3D interactive scene is provided. The method includes executing a first process based on the 2D source image. The first process includes estimating a corresponding depth map for the 2D source image, creating a 3D mesh based on the estimated depth map, and executing a first loop iteratively to present the 3D interactive scene based on the 3D mesh and user's head pose information.
