Barcode Storage and Retrieval for Repeated Scanning Efficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing barcode scanning technologies, such as QR code scanners, require repeated activation of the camera application to scan the same QR code multiple times, as scanned images are temporarily stored and then deleted, limiting user convenience and efficiency in accessing information encoded in barcodes.
Innovation Solution
An electronic device method that acquires a barcode, extracts data, generates an image including the extracted data and a tag, and stores the image in memory, allowing for the retrieval of information associated with the barcode without re-scanning, enabling the display of tags and metadata for multiple barcodes in a single image.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If QR codes are scanned using a camera in preview state, then the scanning function is provided, but the scanned QR codes are temporarily stored in buffer and deleted without being stored in memory, requiring repeated scanning
Solution Approach 1:
The patent applies preliminary action by automatically storing scanned barcode images in memory before they are deleted. The system performs the storage action in advance during the scanning process, so that when users need to access the barcode information later, it is already available in memory without requiring repeated scanning operations.
Solution Approach 2:
The patent introduces an intermediary mechanism (memory storage system) between the camera buffer and the final barcode information. This intermediary ensures that scanned barcodes are preserved in memory rather than being automatically deleted, allowing users to access and retrieve barcode information without repeated scanning.
2Quantity of substance
If only the final preview image is stored in memory, then memory space is saved, but previously scanned QR codes cannot be accessed without re-scanning
Solution Approach 1:
The system performs preliminary storage of all scanned barcode images in memory during the scanning process. This ensures that barcode information is preserved before the preview buffer is cleared, making previously scanned codes accessible for later retrieval without requiring re-scanning.
Solution Approach 2:
The patent implements a feedback mechanism where scanned barcode images are automatically fed back into memory storage. This feedback loop ensures that barcode information is retained and made accessible for subsequent operations, such as displaying tags or retrieving metadata, without requiring the user to re-scan the codes.
3Reliability
If barcode scanning is performed multiple times, then barcode information can be accessed, but user convenience and efficiency are reduced
Solution Approach 1:
The patent applies preliminary action by automatically storing scanned barcodes in memory during the initial scanning process. This preliminary storage ensures that barcode information is reliably available for subsequent operations, eliminating the need for repeated scanning and improving overall scanning efficiency.
Solution Approach 2:
The system performs self-service by automatically preserving scanned barcode images in memory without requiring additional user actions. The system serves itself by maintaining barcode information availability through automatic storage, thereby improving productivity and eliminating redundant scanning operations.
