Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current protective measures for individuals exposed to ionizing energy, such as protective garments and personal dosimeters, are inadequate due to weight, mobility restrictions, limited coverage, degradation of protective layers, and lack of immediate dose monitoring, leading to potential exposure and inefficiencies in workplace safety.
Innovation Solution
A system that uses sensors to detect the presence and location of individuals relative to an emitter of ionizing energy, providing alerts and preventing emitter activation when individuals are in danger zones, and offering real-time information on safe and inefficient zones through visual and auditory feedback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If protective garments are used to shield individuals from ionizing energy, then protection from radiation is improved, but weight and mobility restrictions increase
Solution Approach 1:
The patent extracts the protective function from the physical garment and relocates it to a portable electronic device worn by the individual. The device contains a dosimeter sensor that monitors radiation exposure and provides alerts, separating the protection mechanism from the heavy physical barrier approach.
Solution Approach 2:
The patent replaces the mechanical/physical protective system (heavy lead-lined garments) with an electronic monitoring system. The device uses electronic sensors to detect radiation levels and provides real-time feedback through visual and auditory alerts, substituting physical protection with intelligent monitoring and warning.
2Object-affected harmful factors
If protective garments cover more of the body, then protection coverage is improved, but mobility and dexterity decrease
Solution Approach 1:
The protective function is extracted from the garment and concentrated in a small portable device that can be worn on the body. This single device provides comprehensive monitoring protection without requiring extensive coverage garments that would restrict movement.
Solution Approach 2:
The patent changes the parameter of protection from physical coverage area to electronic monitoring capability. Instead of increasing garment size to cover more body parts, the system uses a compact device with sensors that can detect radiation exposure across different body zones through strategic sensor placement.
3Measurement precision
If personal dosimeters are used to monitor radiation dose, then dose tracking is improved, but immediate warning capability is reduced
Solution Approach 1:
The patent implements a real-time feedback system where the dosimeter continuously monitors radiation exposure and provides immediate visual and auditory alerts when threshold levels are exceeded. The system includes a processor that analyzes dosimeter data and triggers warnings, creating a closed-loop feedback mechanism for instant radiation exposure notification.
Solution Approach 2:
The patent introduces an intermediary processing system between the dosimeter sensor and the user. The processor acts as a mediator that receives raw dosimeter data, compares it against safety thresholds, and generates appropriate warning signals, enabling immediate response capability while maintaining precise measurement functions.
4Object-affected harmful factors
If heavy protective garments are worn for prolonged periods, then radiation protection is maintained, but fatigue and mistakes increase
Solution Approach 1:
The protective function is extracted from the heavy garment and placed in a lightweight portable device. This allows individuals to maintain radiation protection monitoring without the physical burden of heavy garments, thereby reducing fatigue and maintaining work performance throughout prolonged exposure periods.

Data Source
AI summary
A system and method of protecting individuals from ionizing energy is provided. The system can determine a location of an individual with respect to a source of ionizing energy. Before the source emits ionizing energy, the system can determine patterns of ionizing energy expected to be generated by an expected emission from the source. The system can then determine if an individual is within a danger zone in which the individual is expected to receive a dose of ionizing energy above a predetermined amount. The system may also determine if an individual is outside of an optimal zone in which the individual is expected to receive less than a predetermined dose of ionizing energy without being unnecessarily distant from a working area. The system can provide a warning when an individual is within the danger or inefficient zones. Optionally, the system can prevent the source from emitting ionizing energy when an individual is within the danger zone.
