Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current radiation dose meters provide direct, complex values that are difficult for non-expert users to understand, making it challenging to interpret radiation exposure levels and avoid unnecessary exposure, which can increase health risks.
Innovation Solution
A radiation monitoring device with a detector, memory, and controller that computes and displays mean radiation dose values over predetermined time intervals, comparing them to reference values to generate signals indicating safe or unsafe exposure, using a display to show simple, intuitive symbols rather than numerical dose levels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If radiation dose meters provide direct numerical values in predetermined units, then measurement precision is improved, but ease of operation deteriorates because non-expert users cannot understand or interpret the values
Solution Approach 1:
The patent introduces an intermediary processing layer that converts complex radiation dose measurements into simple, intuitive visual indicators. The controller processes raw dose data and transforms it into color-coded symbols (green for safe, yellow for caution, red for dangerous), acting as a mediator between the precise measurement system and the non-expert user interface.
Solution Approach 2:
The patent employs color changes as a visual communication mechanism to convey radiation safety status. Different colors represent different safety levels: green indicates safe exposure, yellow indicates caution, and red indicates dangerous levels. This allows non-expert users to immediately grasp radiation risk without needing to interpret numerical values.
2Loss of information
If radiation dose meters display detailed numerical data, then information completeness is improved, but device complexity increases making the interface harder to use
Solution Approach 1:
The patent extracts only the most critical information from complete radiation dose data for display purposes. Instead of showing all available numerical parameters, the system extracts and displays only the essential safety status through simple symbols and colors, while maintaining access to complete data in memory for reference if needed.
Solution Approach 2:
The patent segments radiation safety information into distinct, easily distinguishable categories represented by different symbols and colors. Rather than presenting a continuous range of numerical values, the system divides the information space into discrete safety zones (safe, caution, dangerous), making the interface simpler while preserving essential information distinctions.
3Measurement precision
If radiation dose meters provide continuous monitoring data, then measurement precision is improved, but ease of operation deteriorates because users cannot quickly assess current safety status
Solution Approach 1:
The patent performs preliminary processing of continuous radiation data by continuously calculating mean dose values and comparing them against predetermined safety thresholds. This preliminary action prepares the information in advance, so when users need to assess safety status, the system has already processed and categorized the data into ready-to-interpret safety indicators.
Solution Approach 2:
The patent implements a feedback mechanism where continuous monitoring data is immediately processed and reflected in the visual display. The system continuously compares current mean dose values with reference values and provides real-time visual feedback through symbol changes, allowing users to quickly assess current safety status without manually analyzing raw data.
