Portable LED Signal Evaluation Device for Indistinct Status Signals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
LED status displays in safety devices, particularly in industrial settings, often lack clear labeling, making it difficult for users to quickly and accurately interpret the device status due to signals that may be imperceptible or indistinguishable to the human eye, especially when emitted in non-visible wavelengths or with short durations.
Innovation Solution
A method using a portable evaluation device equipped with a camera sensor to detect and compare signals from an LED status display with a database, allowing for the assignment and display of device status information, even for signals not clearly visible to humans, and optionally involving a server for further data processing and communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If LED status displays use non-visible wavelengths or short-duration signals to encode device status, then the information capacity and speed of the status display is improved, but the signals become imperceptible or indistinguishable to the human eye
Solution Approach 1:
A portable evaluation device with camera sensor acts as an intermediary between the LED status display and the human user. The device captures signals that are imperceptible to humans (non-visible wavelengths or short-duration flashes) and translates them into visible, interpretable information through its display, enabling users to access status information that would otherwise be undetectable
Solution Approach 2:
The patent replaces direct human visual perception with an electronic camera-based detection system. Instead of relying on human eyes to detect LED signals, the evaluation device uses a camera to capture and process the optical signals, substituting biological detection with electronic sensing and image processing capabilities
2Ease of operation
If LED status displays emit signals in the visible wavelength range for direct human perception, then the ease of operation is improved, but the speed and information capacity of the status display is limited
Solution Approach 1:
The evaluation device creates a visual copy of the LED status signals through its display. The camera captures the LED emissions and the device's display reproduces the status information in a form that is easily interpretable by humans, maintaining ease of operation while enabling detection of signals that would otherwise be imperceptible
3Ease of operation
If detailed labeling is provided for each LED signal to improve user understanding, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The evaluation device provides self-service by automatically capturing, analyzing, and displaying the meaning of LED status signals. Instead of requiring users to manually interpret complex LED patterns or refer to external documentation, the device autonomously detects the signals and presents the information in an easily understood format through its display
