Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If three-dimensional imaging and virtual reality systems are used to create three-dimensional virtual scenes, then the ability to interact with three-dimensional environments is improved, but the device complexity and setup requirements increase
Solution Approach 1:
The patent creates a simplified copy of the three-dimensional environment through photogrammetry, generating a three-dimensional model from multiple two-dimensional images. This allows users to interact with a digital representation without requiring complex specialized hardware, as the system uses standard cameras and smartphones to capture and reconstruct the environment.
Solution Approach 2:
The patent introduces an intermediary processing system that automatically converts multiple images into a three-dimensional model through photogrammetry. This intermediary layer handles the complexity of 3D reconstruction, allowing end users to simply load and view the model without dealing with the underlying technical complexity of image processing and 3D rendering.
2Reliability
If specialized three-dimensional viewing devices are used, then the quality of three-dimensional interaction is improved, but the ease of operation decreases
Solution Approach 1:
The patent makes the three-dimensional viewing system universal by allowing interaction through standard devices like smartphones and computers. The system can be accessed via web browsers without requiring specialized software or hardware, enabling any user with a basic device to view and interact with three-dimensional models through intuitive controls.
Solution Approach 2:
The system provides self-service functionality by automatically generating three-dimensional models from images without requiring user involvement in the complex processing steps. Users simply need to load the pre-processed model into the viewer, and the system handles all the technical aspects of 3D rendering and interaction automatically.
3Measurement precision
If complicated setups are required for three-dimensional virtual reality systems, then the measurement precision is improved, but the ease of manufacture and deployment worsens
Solution Approach 1:
The patent segments the measurement process into two distinct phases: the first phase involves automated photogrammetric reconstruction from multiple images, and the second phase involves simple user interaction with the generated model. This segmentation allows high measurement precision to be achieved through automated processing while keeping the deployment process simple and accessible to end users.

AI summary
A system configured to generate a three-dimensional scene of a physical environment. In some cases, the system may present the three-dimensional scene such that the user is able to view the model in various different types. The system may also allow the user to capture various measurements associated with the scanned physical environment by selecting different portions of the scene.
