Optical Reader With Integrated Display For Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Fixed optical information reading devices lack a convenient display for setting and maintenance tasks, making it difficult for users to adjust and maintain the device without a connected computer, as they rely on external equipment for settings and feedback.
Innovation Solution
Incorporating an image display section that captures and decodes two-dimensional codes, displays matching levels, and controls reading conditions, allowing for on-device tuning and maintenance without external computer assistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If all setting work and maintenance functions are integrated into the reader alone, then user convenience is improved, but device size increases
Solution Approach 1:
The patent embeds a display device inside the reader housing, creating a nested structure where the display is integrated within the existing device boundaries. This allows the reader to provide setting and maintenance functions independently while minimizing the increase in external device size.
Solution Approach 2:
The patent utilizes the vertical dimension by positioning the display device on the rear surface of the reader, allowing information display without expanding the horizontal footprint. This dimensional approach enables independent operation while maintaining compact form factor suitable for production line installation.
2Ease of operation
If a display device is added to show setting and maintenance information, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The display device serves multiple functions: displaying setting information, showing maintenance status, presenting decoding results, and providing operational feedback. This multi-functionality consolidates various information display needs into a single component, improving ease of operation without proportionally increasing device complexity.
Solution Approach 2:
The display device provides real-time feedback during setting and maintenance operations, showing matching levels, decoding success rates, and operational status. This feedback mechanism enables users to independently adjust and monitor the reader without external equipment, simplifying operation while the feedback system itself manages the complexity of monitoring multiple parameters.
3Ease of operation
If the reader operates independently without external computer connection, then ease of operation is improved, but loss of information increases
Solution Approach 1:
The display device provides comprehensive feedback including matching levels, decoding success rates, and operational status, ensuring that all critical information needed for setting and maintenance is available locally. This feedback system eliminates information loss by presenting all necessary data directly to the user without requiring external computer connection.
Solution Approach 2:
The reader performs setting and maintenance functions independently using its own processing capabilities and display device. The arithmetic operation section calculates matching levels and the display device presents results, enabling the system to serve itself without external assistance while maintaining full information availability for operational decisions.
Data Source
AI summary
Provided is an optical information reading device that displays, as an image, information that can be conveniently checked in setting work and in maintenance work. A decoding unit decodes image data acquired by an imaging element, and an arithmetic operation unit arithmetically operates a matching level indicating easiness of the decoding of a code, stability of the decoding, a margin of the decoding or pixel-per-cell in the decoding unit. Furthermore, a UI management unit and an image display device display, as an image, at least one of the matching level, the image data acquired by the imaging element, and an average success rate (reading success rate) of the decoding obtained by decoding a plurality of pieces of image data obtained by capturing an image of the code a plurality of times.
