Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current parcel locker systems face issues with user errors during shipment deposit and collection processes, inefficient management of compartment space, and the inability to accurately validate shipments due to limitations in existing identification technologies, leading to errors and inefficiencies in tracking and handling.
Innovation Solution
The implementation of an UHF RFID system that allows for automatic identification and validation of shipments within electronic parcel lockers, using RFID tags and compartment-specific antenna designs to enable efficient reading and management of shipments without manual entry, optimizing deposit, collection, and compartment usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual entry of shipment identifiers is used, then the system can identify shipments, but user errors occur and tracking accuracy deteriorates
Solution Approach 1:
The patent replaces manual barcode scanning with RFID technology. RFID tags are automatically read by RFID readers in the parcel locker, eliminating the need for manual intervention. This substitution of mechanical/manual operations with automated electromagnetic field-based reading resolves the contradiction by preventing user errors while maintaining identification accuracy.
Solution Approach 2:
The RFID system enables automatic identification without requiring user action. The tags on shipments are automatically detected and read by the system as shipments enter the locker, making the identification process self-service and removing human error from the equation.
2Productivity
If manual selection of compartment size is required, then compartment space can be managed, but the deposit process becomes time-consuming
Solution Approach 1:
The system automatically determines the appropriate compartment size based on RFID read data and shipment information stored in the system. The control unit autonomously selects and opens the correct compartment without requiring the carrier agent to manually search or select, making the process self-service and significantly faster.
Solution Approach 2:
The system pre-configures compartment assignments based on previous shipments and carrier patterns. When a carrier arrives, the system has already prepared the appropriate compartment selection based on stored data, eliminating the need for real-time manual selection and reducing deposit time.
3Measurement precision
If weighing systems are implemented, then shipment presence can be detected, but weighing errors occur especially for lightweight shipments
Solution Approach 1:
The patent replaces the mechanical weighing system with an RFID-based identification system. Instead of measuring weight to detect shipments, the system uses RFID readers to automatically detect and identify shipments through their tags. This substitution eliminates weighing errors for lightweight items while maintaining reliable shipment detection.
4Productivity
If barcode reading is used for shipment identification, then shipments can be identified, but manual positioning and scanning is required which is time-consuming
Solution Approach 1:
The system replaces optical barcode reading with electromagnetic field-based RFID reading. RFID readers can automatically detect and read multiple tags simultaneously without requiring manual positioning or scanning actions, significantly improving identification efficiency and eliminating time loss.
Solution Approach 2:
The RFID system performs automatic identification without requiring user interaction. As shipments enter the locker area, the RFID readers automatically detect and read the tags, making the identification process self-service and eliminating the time-consuming manual scanning required by barcode systems.
