Solution Overview
Problem
Current methods for managing risks in radioactive zones, such as irradiation and contamination, rely on outdated paper cartography and oral communication, which are not real-time and difficult to share, leading to inefficiencies and safety concerns due to the limitations of existing technologies like teledosimetry and supervision systems in environments with high electromagnetic interference.
Innovation Solution
A method utilizing augmented reality devices, such as Microsoft Hololens, to display discrete holographic symbols indicating radiation intensity, allowing operators to visualize dose rates in real-time and share data through a digital model, enhancing safety by providing immediate and accessible risk information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If paper maps and oral communication are used to share risk information, then the system is simple to implement, but the information is not real-time and difficult to share
Solution Approach 1:
The patent uses holographic projections to create visual copies of radiation risk information in the environment. Operators can see holographic representations of dose rates and contamination levels projected in real-time at relevant locations, enabling immediate information sharing without requiring complex electronic displays or communication systems.
Solution Approach 2:
The patent replaces traditional mechanical information delivery methods (paper maps, oral briefings) with optical holographic projections. This substitution enables real-time, visual information presentation that can be viewed by multiple operators simultaneously without requiring physical distribution or verbal communication.
2Reliability
If teledosimetry and supervision systems are used, then dosimetry monitoring is improved, but the systems are impacted by electromagnetic disturbances in the reactor building
Solution Approach 1:
The patent uses holographic projections as an intermediary to display radiation information. Instead of directly transmitting dosimetry data through electromagnetic waves that are blocked by concrete walls, the system projects visual representations of dose rate information that can be viewed by operators in the controlled area without requiring direct electromagnetic communication through the concrete barriers.
Solution Approach 2:
The system creates visual copies of dosimetry information through holographic projections, allowing operators to view real-time radiation levels without requiring direct electronic transmission through electromagnetic waves that are blocked by the reactor building's concrete structure.
3Reliability
If protective equipment is worn to limit radiation exposure, then operator safety is improved, but the operator's field of vision is limited
Solution Approach 1:
The patent projects holographic information into three-dimensional space around the operator, allowing risk information to be displayed in the environmental dimension rather than on a two-dimensional screen in front of the operator. This enables operators to view radiation information without removing their protective equipment or having it obstruct their view.
Solution Approach 2:
The holographic projection acts as an intermediary that presents information in the operator's field of view without requiring the operator to remove protective equipment. The projections can be positioned in the environment around the operator, allowing safe viewing while maintaining protective gear.
4Reliability
If real-time measurement and display of radiation levels is implemented, then safety is improved, but the system complexity increases
Solution Approach 1:
The patent replaces complex electronic display systems with holographic projection technology. This substitution allows real-time radiation information to be displayed visually in the environment, simplifying the overall system architecture while maintaining real-time monitoring capabilities and improving operator awareness.
