Picking Trolley Automated Imaging Inspection System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing picking trolley systems impose a heavy burden on operators when scanning large quantities of articles, leading to potential counting errors due to scan omissions or multiple scans.
Innovation Solution
The system includes an inspection table, an imaging unit that captures images of articles and generates image information, a reading unit that reads article information from the images, and a processing unit that collates the article information to determine if the articles match the picking instructions, thereby reducing counting errors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a scanner is used to read article information manually, then the picking operation can be performed with simple equipment, but the operator burden increases and counting errors occur due to scan omissions or multiple scans
Solution Approach 1:
The patent replaces the manual mechanical scanning operation with an automated imaging system. The imaging unit captures images of articles on the inspection table, and image processing automatically reads article information, eliminating the need for operators to manually operate scanners and reducing both operator burden and counting errors.
Solution Approach 2:
The system enables self-service by allowing the inspection table and imaging unit to automatically perform article identification and counting. The articles themselves are inspected through automated image capture and processing, without requiring operator intervention for each scanning operation.
2Productivity
If manual scanning is used for each article, then the equipment complexity remains low, but the productivity decreases due to the heavy operator burden
Solution Approach 1:
The patent replaces repetitive manual scanning operations with an automated imaging and image processing system. This substitution increases productivity by eliminating manual labor bottlenecks while introducing automated equipment, achieving a balance between productivity improvement and acceptable system complexity.
Solution Approach 2:
The imaging unit and image processing system serve as intermediaries between the articles and the picking control system. Instead of direct manual scanning, the intermediary automated system captures article information through imaging and processing, enabling efficient data extraction without direct operator involvement in each scanning action.
3Measurement precision
If automated image capture is used to read article information, then counting accuracy improves, but the device complexity increases due to additional imaging and processing components
Solution Approach 1:
The patent replaces manual scanning operations with automated image capture and processing. This substitution improves measurement precision by eliminating human error in scanning operations while introducing automated imaging equipment, achieving accurate article identification through technological automation.
Solution Approach 2:
The system creates visual copies of articles through image capture. Instead of direct physical interaction with articles during identification, the imaging unit creates digital copies (images) that are then processed to extract article information, enabling accurate identification without direct manual handling.

Function Achieved in This Case
The system efficiently reduces counting errors by automatically reading and matching article information, minimizing operator burden and improving the accuracy of the picking operation.
Implementation Method 1
an imaging unit that captures an image of the inspection target article placed on the inspection table and generates image information
Data Source
AI summary
A picking trolley includes a storage shelf portion on which a storage portion is placed, an inspection table, an imaging unit, a reading unit, a storage unit, a processing unit that generates inspection result information indicating whether an inspection target article corresponds to a picking article, and a display unit. The inspection result information includes inspection number information obtained by counting, as the picking article, the inspection target article including article information matching article information of the picking article. The processing unit determines that picking is completed when there is no inspection failure article that is the inspection target article including article information that does not match the article information of the picking article, there is no undecipherable article that is the inspection target article including article information that is unable to be read normally, and the inspection number information and the instruction number information match.
