Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If 3D objects are positioned independently within the 2D environment using conventional tools, then the ease of operation is improved, but the manufacturing precision (alignment accuracy) deteriorates
Solution Approach 1:
The patent introduces virtual walls as intermediary elements between the 3D objects and the 2D environment. These virtual walls serve as alignment references that mediate the positioning process, allowing users to easily place objects while achieving precise alignment through the wall's guiding functionality.
Solution Approach 2:
The patent replaces manual mechanical alignment processes with automated computational geometry. By calculating perspective and scale transformations based on detected wall planes, the system automatically positions 3D objects with high precision without requiring manual adjustment, substituting mechanical user effort with computational accuracy.
2Ease of operation
If conventional interior design tools are used to position 3D objects, then the ease of operation is improved, but the measurement precision (scale and perspective accuracy) deteriorates
Solution Approach 1:
The patent implements a feedback mechanism where the system continuously detects and adjusts based on the actual 2D environment's perspective and scale. By comparing the detected wall planes with the desired 3D object placement, the system provides real-time feedback to automatically adjust positioning, ensuring accurate scale and perspective while maintaining ease of operation.
Solution Approach 2:
The patent dynamically changes the parameter representations of the 2D environment by calculating and applying perspective transformations and scale factors. These parameter changes allow the system to accurately represent 3D objects in the 2D environment while maintaining proper scale and perspective relationships, resolving the measurement precision issue.
3Ease of operation
If 3D objects are positioned without wall alignment references, then the ease of operation is improved, but the manufacturing precision (alignment with wall planes) deteriorates
Solution Approach 1:
The patent segments the 2D environment into distinct wall planes and regions based on detected lines and geometric features. This segmentation creates multiple alignment references (virtual walls) that can independently guide object positioning, allowing users to easily place objects while achieving precise alignment with each wall plane through the segmented reference system.

AI summary
Example systems and methods for virtual visualization of a three-dimensional (3D) model of an object in a two-dimensional (2) environment. The method may include capturing the 2D environment and adding scale and perspective to the 2D environment. Further, a user may select intersection points on a ground plane of the 2D environment to form walls, thereby converting the 2D environment into a 3D space. The user may further add 3D models of objects on the wall plane such that the objects may remain flush with the wall plane.
