Barcode Reader Automatic Mode Switching for Decoding Accuracy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional barcode readers often incorrectly decode barcodes when multiple codes are present in the field of view, requiring users to manually switch between pick mode and non-pick mode, which is time-consuming and reduces readability.
Innovation Solution
A barcode reader with an imager and processor that automatically switches between pick mode and non-pick mode based on the number of barcodes detected within the field of view, allowing seamless operation without user input, ensuring accurate decoding of the intended barcode.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If pick mode is enabled to handle multiple barcodes, then barcode selection capability is improved, but readability and operation speed deteriorate
Solution Approach 1:
The system dynamically adjusts the decoding mode (pick mode vs. non-pick mode) based on the number of barcodes detected in the field of view. When multiple barcodes are detected, pick mode is automatically activated; when a single barcode is detected, non-pick mode is used. This dynamic adaptation resolves the contradiction by applying the appropriate mode only when necessary.
2Adaptability or versatility
If manual mode switching is implemented, then mode control flexibility is improved, but operation time and complexity increase
Solution Approach 1:
The barcode reader automatically determines whether to enter or exit pick mode by detecting the number of barcodes in its field of view, eliminating the need for manual user intervention. The system self-adjusts its operation mode based on real-time barcode detection, thereby reducing operation time while maintaining flexible adaptability.
3Measurement precision
If pick mode is used for multiple barcodes, then decoding accuracy is improved, but operational complexity increases
Solution Approach 1:
The system dynamically switches between pick mode and non-pick mode based on the detected number of barcodes. When multiple barcodes are present, pick mode is activated to ensure accurate selection and decoding. When only one barcode is present, non-pick mode is used for simpler operation. This dynamic approach maintains decoding accuracy while reducing operational complexity in single-barcode scenarios.

AI summary
The disclosure relates to a barcode reader configured to operate in either a non-pick mode or a pick mode, such that the barcode reader is configured to automatically switch between the non-pick mode and the pick mode in response to detecting the number of barcodes currently present within the field-of-view of the barcode reader.
