Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Manual inventory taking in large warehouses is time-consuming and often inaccurate, leading to delays in product delivery and production processes due to the physical characteristics of high-rise racks and limitations of existing electronic systems.
Innovation Solution
An automated inventory taking system utilizing remote electronic identification means, such as RFID tags, and a mobile device with RFID tag reading capabilities, wireless information transmission, and control mechanisms to quickly and accurately gather and process inventory data from high-rise racks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual inventory taking is used, then the system can operate with simple equipment, but the accuracy and speed of inventory information are insufficient
Solution Approach 1:
The patent replaces manual mechanical inventory taking with an automated electronic identification system. RFID readers automatically detect and read electronic tags on products as they pass through the warehouse, eliminating the need for manual scanning and data entry. This substitution of mechanical/manual operations with electronic automation directly improves measurement precision while managing device complexity through standardized electronic components.
Solution Approach 2:
The inventory system operates autonomously by having products carry their own electronic identification tags. As products move through the warehouse on conveyors or racks, the RFID readers automatically detect and read the tags without human intervention. The system self-updates inventory records in real-time, eliminating the need for manual inventory taking and significantly improving accuracy.
2Productivity
If manual inventory taking is used, then the equipment cost is low, but the time consumption and delays in production processes increase
Solution Approach 1:
The RFID-based inventory system operates continuously as products move through the warehouse. Readers are positioned along the product flow path and automatically scan tags without interruption. This continuous operation eliminates the periodic stoppages required for manual inventory counting, maintaining constant productivity while drastically reducing the time lost to inventory operations.
Solution Approach 2:
Products are equipped with electronic identification tags before entering the warehouse workflow. This preliminary tagging allows the system to automatically identify and track products as they arrive, eliminating the need for time-consuming manual identification and data entry during inventory operations. The preliminary action of tagging enables real-time tracking throughout the entire product lifecycle in the warehouse.
3Reliability
If manual inventory taking is used, then the system is simple to operate, but the information does not reflect the real existences and quantities of products
Solution Approach 1:
The RFID inventory system provides real-time feedback to the central control system as products move through the warehouse. Each time a product passes an RFID reader, the reader immediately transmits the tag information to update inventory records. This continuous feedback loop ensures that inventory information reliably reflects the actual presence and quantity of products, eliminating the delays and inaccuracies of manual reporting.
