Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current metal detectors in sensitive environments are inefficient in distinguishing between metallic objects and radioactive radiation, leading to prolonged processing times and difficulties in interpreting alarm signals for security personnel, which slows down the flow of people and causes discomfort, especially for the elderly.
Innovation Solution
A portal metal detector equipped with a power supply and processing module that controls a series of light sources to emit different colors based on the nature of the detected signal, allowing immediate visualization of the detection type and location, with red for metallic masses, blue for radioactive radiation, and green for no anomalies, facilitating quicker security response and transit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If metal detectors detect both metallic objects and radioactive radiation, then detection capability is improved, but interpretation difficulty increases
Solution Approach 1:
The patent applies color-coded visual indicators to represent different detection results: red for metallic objects, blue for radioactive radiation, and green for no anomaly. This color change system enables security personnel to immediately distinguish between different types of detected objects without complex interpretation, resolving the contradiction by maintaining versatile detection capability while simplifying signal interpretation through intuitive visual cues.
2Measurement precision
If security personnel analyze alarm signals carefully, then detection accuracy is improved, but passage time increases
Solution Approach 1:
The system performs preliminary classification of detected objects by type (metallic vs. radioactive) and provides this information in advance through color-coded indicators before security personnel need to make decisions. This preliminary action of categorizing and visually presenting detection results eliminates the need for time-consuming analysis during the passage process, thereby maintaining detection accuracy while significantly reducing passage time.
3Loss of information
If multicolored light-emitting diodes are used to visualize signal amplitude, then information delivery is improved, but interpretation difficulty increases
Solution Approach 1:
Instead of using multicolored LEDs to represent signal amplitude as proposed in prior art, this patent applies color coding to represent the local quality or type of detected object at specific locations. Red indicates metallic objects, blue indicates radioactive radiation, and green indicates no anomaly. This local quality approach assigns different meanings to colors based on the nature of the detected object rather than its amplitude, making the information immediately interpretable and eliminating the confusion associated with amplitude-based color representation.
