Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If conventional radiation monitoring tools (detectors, badges, rings) are used, then radiation levels can be monitored and measured, but the ability to intuitively and interactively convey complex three-dimensional radiation information is limited
Solution Approach 1:
The patent transforms two-dimensional radiation data representations into three-dimensional immersive visualizations that users can explore from multiple angles. The system renders radiation fields, dose distributions, and anatomical structures in 3D space, allowing users to rotate, zoom, and interact with the data spatially, thereby conveying complex three-dimensional radiation information more effectively than conventional flat displays.
Solution Approach 2:
The patent introduces augmented reality devices and immersive visualization systems as intermediaries between radiation monitoring tools and users. These intermediaries transform raw radiation data into intuitive visual representations, bridging the gap between complex measurement data and user comprehension, thereby enabling interactive exploration of radiation information.
2Reliability
If physical radiation monitoring tools are used, then radiation levels can be evaluated, but immersive training and operational tools are unavailable
Solution Approach 1:
The patent creates virtual copies of radiation environments, anatomical structures, and monitoring scenarios that can be used for training and analysis without exposing users to actual radiation hazards. These digital twins allow trainees to practice in realistic simulated environments while maintaining safety, and enable operational teams to analyze scenarios without physical presence in hazardous areas.
Solution Approach 2:
The patent develops a multi-functional system that serves both operational radiation monitoring and training purposes. The same immersive visualization platform is used for real-time radiation field analysis during operations and for training scenarios, allowing the system to adapt between different use cases while maintaining reliability in both contexts.
3Measurement precision
If conventional tools are used for radiation monitoring, then momentary and accumulated levels can be assessed, but effective and interactive visualization is limited
Solution Approach 1:
The patent implements dynamic visualizations that update in real-time as radiation data is collected, allowing users to observe temporal changes in radiation fields. The system animates dose accumulation over time, shows moving radiation sources, and provides temporal controls for reviewing historical data, thereby preserving both spatial and temporal dimensions of radiation information interactively.
Data Source
AI summary
Interactive augmented-reality technologies track simulated-radiation exposure of a user moving through a physical scene. The simulated-radiation exposure tracking is performed using radiation voxels associated with a simulated radiation field caused as if a radioactive source of a particular type was emitting radiation from a predetermined location of the scene. Each radiation voxel is indicative of a respective level of the simulated radiation field at the voxel's scene location.
