Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If inspectors collect and integrate information from various sources manually, then they can access comprehensive equipment information, but operational efficiency decreases and time consumption increases
Solution Approach 1:
The patent creates a virtual copy of the real equipment environment using 3D scanning and point cloud technology. The virtual scene replicates the physical equipment, allowing inspectors to access all equipment information digitally without manual data collection, thus maintaining information completeness while dramatically improving operational efficiency
Solution Approach 2:
The patent merges multiple information sources (equipment data, operational procedures, training materials) into a single integrated augmented reality interface. This consolidation allows inspectors to access comprehensive information through one unified system rather than collecting data from multiple separate sources, resolving the contradiction between information completeness and operational efficiency
2Loss of information
If a mentorship system is used for training inspectors, then human experience can be transmitted, but the transmission process is difficult and time-consuming
Solution Approach 1:
The patent captures and stores expert operational knowledge in the form of standardized procedures within the virtual environment. These procedures are then delivered through augmented reality guidance to trainees, copying the expert's knowledge base without requiring direct mentorship interaction, thus preserving knowledge effectiveness while eliminating time-consuming apprenticeship periods
Solution Approach 2:
The patent pre-processes and structures all necessary operational knowledge and procedures into the virtual environment before training begins. Standardized operating procedures are prepared in advance and made immediately accessible to inspectors through AR interfaces, eliminating the need for time-consuming on-the-job learning from mentors
3Reliability
If specialized operational procedures are documented, then expertise can be preserved, but replication of these procedures remains difficult
Solution Approach 1:
The patent creates digital copies of specialized procedures within the virtual environment, allowing exact replication of expert operations. The standardized procedures are stored as structured data that can be consistently reproduced across multiple inspectors without degradation, solving both the reliability of standardization and the ease of replication
Solution Approach 2:
The patent pre-structures all specialized procedures into standardized formats within the virtual environment, with clear step-by-step instructions and visual guides. This preliminary organization makes procedure replication trivial for inspectors, as they simply follow the pre-prepared guidance rather than attempting to replicate complex procedures from memory or documentation
4Measurement precision
If virtual objects are created with accurate proportional relationships, then spatial accuracy is improved, but computational complexity increases
Solution Approach 1:
The patent establishes a default proportional relationship parameter between virtual and real-world dimensions. By defining this scaling factor once during system initialization, the patent achieves accurate spatial correspondence without requiring complex real-time calculations, thus maintaining measurement precision while minimizing processing complexity

Data Source
AI summary
This system is designed for establishing augmented reality and includes the following components: an optical radar configured to scan a real scene to obtain three-dimensional spatial information, where the scene includes a target object of a first size; and a processor connected to the optical radar. The processor converts the three-dimensional spatial information into a point cloud map and executes a virtual environment development engine. This engine creates a virtual scene corresponding to the real scene and generates a virtual object corresponding to the target object based on the point cloud map. The virtual object has a second size, set according to a default proportional relationship, and the engine establishes augmented reality elements around the virtual object to present operational content related to the target object.
