Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Operators unfamiliar with the operation of code symbol reading apparatuses struggle to determine the correct direction and position for a barcode, leading to prolonged adjustment times and reduced efficiency in reading code symbols.
Innovation Solution
A code symbol reading apparatus is equipped with a decoder, candidate area detection unit, and direction determination unit that detects and notifies the optimal direction for higher decoding rates of the barcode, displaying guide messages to assist operators in adjusting the barcode's position for accurate reading.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If real-time dynamic image display is provided to allow operator recognition of reading state, then reading state visibility is improved, but operator adjustment time increases for unfamiliar users
Solution Approach 1:
The system provides real-time feedback by displaying the captured image on an image display unit, allowing operators to see the current reading state. The candidate area detection unit identifies potential barcode regions and displays them with overlays, giving continuous feedback on reading progress and guiding operator adjustments.
Solution Approach 2:
The patent introduces an intermediary processing system that includes a candidate area detection unit and direction determination unit. These intermediaries analyze the captured image, determine the optimal reading direction, and provide guidance information to the operator, bridging the gap between raw image data and operator decision-making.
2Ease of operation
If manual adjustment by operator is required to position code symbol, then operational flexibility is maintained, but reading efficiency decreases for unfamiliar operators
Solution Approach 1:
The system performs self-service by automatically detecting candidate barcode areas and determining the optimal reading direction without operator intervention. The direction determination unit autonomously analyzes image characteristics and provides guidance information, allowing the system to serve itself in positioning and orientation tasks.
Solution Approach 2:
The patent replaces manual mechanical adjustment with automated image processing and direction determination. Instead of relying on operator manual positioning, the system uses computational algorithms to detect barcode candidates and calculate optimal reading directions, substituting mechanical operator actions with automated digital processing.
3Productivity
If automated direction determination is added to guide operators, then reading efficiency is improved, but device complexity increases
Solution Approach 1:
The candidate area detection unit and direction determination unit serve multiple functions: they detect barcode candidates, determine optimal reading directions, provide guidance information, and adapt to different barcode types. This multi-functionality reduces the need for separate specialized components for each task.
Solution Approach 2:
The patent introduces intermediary processing units that act as mediators between the camera and the operator. These intermediaries handle the complex image analysis and direction determination tasks, shielding the operator from complexity while maintaining system functionality.
Data Source
AI summary
According to one embodiment, a code symbol reading apparatus includes a decoder, a candidate area detection unit, a direction determination unit, and a direction notification unit. The decoder decodes a code symbol attached to an article, based on an image picked up by a camera. The candidate area detection unit detects an image area to be a candidate of the code symbol from the image of the article picked up by the camera. The direction determination unit determines such a direction that a decoding rate of the code symbol becomes higher based on the image area detected by the candidate area detection unit when the decoder cannot decode the code symbol. The direction notification unit notifies of the direction determined by the direction determination unit.
