Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Optical imaging devices face challenges in efficiently capturing and decoding multiple symbologies in a specific order, particularly in handheld and portable settings, where ambient light conditions and the need for precise illumination can affect image quality and data extraction.
Innovation Solution
A method for operating a handheld optical indicia reader that includes capturing images of setup symbologies, sorting and sequencing them using a graphic user interface (GUI), storing the order, and then decoding and outputting symbologies in that order, with the ability to prioritize and configure decoding based on user-defined settings, utilizing a processor and image sensor for accurate data extraction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple symbologies are captured in a single image, then the productivity of data collection is improved, but the difficulty of detecting and measuring the correct decoding order increases
Solution Approach 1:
The system performs preliminary actions by capturing setup symbologies in advance, displaying them on a GUI, and allowing the user to define and store the desired decoding sequence before actual data collection. This pre-configuration eliminates the need to determine decoding order in real-time, resolving the contradiction between capturing multiple symbologies efficiently and identifying their correct decoding order.
2Ease of operation
If the device is made portable and wireless, then the ease of operation is improved, but the reliability of data transmission and processing may deteriorate
Solution Approach 1:
The system performs preliminary configuration and sequencing setup before actual data collection, storing the decoding order locally in the portable device. This ensures that even in wireless portable settings where transmission may be interrupted or unreliable, the device can independently determine and execute the correct decoding sequence, maintaining reliability while preserving portability benefits.
