Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional picking systems in logistics centers lack real-time monitoring and verification of picking accuracy, leading to inefficiencies and performance quantification challenges due to potential mistakes in item selection and staff authorization.
Innovation Solution
A picking system incorporating a radio frequency identification (RFID) tag and a two-wire conductive strip, where the RFID tag is attached to operating staff, and the identifying unit reads and responds to tag information via the conductive strip, communicating with a processing unit to ensure accurate item selection and staff authorization, and evaluates staff performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional labels are used to show product information, then the picking system is simple and easy to operate, but the picking accuracy cannot be monitored and verified in real-time
Solution Approach 1:
The patent replaces conventional mechanical label-reading systems with RFID (radio frequency identification) technology. RFID tags are attached to products and readers are positioned at picking locations, enabling wireless, contactless identification and verification of picked items. This substitution eliminates the need for physical label inspection while providing automated real-time verification, thereby improving picking accuracy without requiring complex manual monitoring processes.
Solution Approach 2:
The patent introduces RFID tags as intermediary carriers of product information and identification data. These tags mediate between the physical product and the verification system, storing unique identifiers that can be read remotely. The tags serve as intermediaries that enable automatic verification without direct line-of-sight contact between readers and products, facilitating accurate tracking and verification while maintaining system simplicity.
2Productivity
If multiple operating staff pick items simultaneously without monitoring, then the picking operation is efficient and fast, but mistakes such as picking wrong items or placing products into wrong order receptacles occur
Solution Approach 1:
The patent implements a feedback mechanism where RFID readers continuously scan for tags as staff pick items, and the system immediately verifies whether the picked item matches the required item for the current order. The system provides real-time feedback through visual or audible signals to confirm correct picking or alert staff of errors. This immediate feedback loop enables multiple staff to work simultaneously while maintaining high accuracy through automated verification.
Solution Approach 2:
The system enables self-service verification where the RFID technology automatically identifies and verifies picked items without requiring manual intervention from supervisors or quality checkers. The automated system independently validates each picking action by comparing RFID tag data against the order requirements, allowing staff to focus on picking operations while the system handles verification, thus maintaining both efficiency and accuracy.
3Ease of manufacture
If conventional labeling systems are used, then the system is easy to manufacture and deploy, but staff performance cannot be quantified or evaluated
Solution Approach 1:
The patent implements continuous data collection through RFID readers that operate throughout the entire picking process. Every interaction with products is automatically recorded, including which staff member picked which item and at what time. This continuous recording creates a comprehensive data trail that enables performance evaluation without interrupting or complicating the picking workflow, maintaining ease of implementation while capturing detailed performance metrics.
Solution Approach 2:
The RFID tags and readers serve as intermediaries that automatically capture and transmit performance data between staff actions and the central system. This intermediary data collection mechanism records picking accuracy, speed, and compliance information without requiring additional manual data entry or complex monitoring equipment, thus maintaining system simplicity while enabling comprehensive performance tracking and evaluation.

AI summary
A picking system comprises a radio frequency identification (RFID) tag, a case, a two-wire conductive strip, at least one identifying unit and a processing unit. The two-wire conductive strip is electrically connected between the identifying unit and the processing unit. The identifying unit reads tag information within the RFID tag for actively and instantly controlling the authorization of an operating staff assigned for particular items thereby improving the accuracy of picking items.
