Optical Reader Error Analysis via Triggered Image Capture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current optical information readers lack the capability to efficiently identify the cause of errors, leading to wasteful work and incorrect attribution of failures, as they simply stop operating without diagnosing the root cause of issues, often misattributing problems to the reader itself rather than other factors.
Innovation Solution
An optical information reading system that includes a trigger input, imaging, and output components to capture and store images and timing data, allowing for the display of success or failure information and associated images, enabling the management device to analyze and display these results for easy identification of error causes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the optical information reader simply stops operation when an error occurs, then the device complexity is reduced, but the ability to identify error causes deteriorates
Solution Approach 1:
The imaging part captures images in advance at predetermined timing intervals before the reading process times out, so that when an error occurs, the captured images are already available for analysis. This preliminary action of capturing images before the error is fully manifested allows for effective error cause identification without adding complex post-error analysis systems.
2Difficulty of detecting and measuring
If multiple images are captured and stored for each trigger signal, then the ability to identify error causes is improved, but the loss of time for data management increases
Solution Approach 1:
The system extracts and stores only the essential information needed for error analysis - specifically, images captured at predetermined timing intervals associated with each trigger signal. By taking out only the relevant images rather than storing all possible data, the system enables effective error identification while minimizing the time and resources needed for data management.
3Reliability
If the imaging part captures images until the reading process times out, then the reliability of error diagnosis is improved, but the use of energy increases
Solution Approach 1:
The imaging part operates periodically at predetermined timing intervals rather than continuously, capturing images only at specific moments during the reading process. This periodic operation maintains reliable error diagnosis capability by capturing critical frames while significantly reducing energy consumption compared to continuous imaging.
