Industrial Truck RFID Display Unit for Real-Time Transport Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional industrial truck systems rely on central data transmission for driving orders, which can lead to inefficiencies and errors in transport processes, as operators receive orders remotely and may not be immediately aware of the goods' transport conditions.
Innovation Solution
An industrial truck equipped with a decentralized transmitter and receiver unit, preferably using RFID transponders, reads data from loads and load carriers, allowing it to autonomously determine transport destinations and conditions, such as maximum permissible speed, and displays this information to the operator through a display unit, eliminating the need for central data transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a central data transmission system is used to provide driving orders to operators, then the system structure is simple and centralized control is achieved, but the operator cannot access real-time transport information directly from goods and errors in transport orders are not immediately detectable
Solution Approach 1:
The industrial truck autonomously reads transport information directly from RFID transponders on goods and load carriers without requiring central system intervention. The evaluation unit on the truck itself processes the data and determines transport conditions, enabling the system to serve itself and eliminating information loss between central systems and operators.
Solution Approach 2:
RFID transponders serve as intermediaries carrying transport information on goods and load carriers. The transmitting and receiving unit on the industrial truck reads data from these transponders, which act as mediators between the goods and the truck's control system, providing real-time information access without complex central transmission infrastructure.
2Ease of operation
If transport information is transmitted centrally via radio to the industrial truck, then the system requires less on-truck hardware, but the operator receives orders remotely and is not in close proximity to the goods for verification
Solution Approach 1:
The patent replaces radio frequency data transmission with direct electromagnetic reading of RFID transponders. The transmitting and receiving unit reads transport information directly from transponders on goods at close proximity, eliminating the need for continuous radio transmission and reducing energy consumption while improving operator access to transport data.
3Reliability
If the industrial truck reads data decenterally from loads and load carriers using RFID transponders, then real-time transport information is immediately available to the operator, but the device complexity increases with additional transmitting and receiving units
Solution Approach 1:
The transmitting and receiving unit is designed as a multi-functional device that performs multiple operations: reading RFID transponders on goods, reading transponders on load carriers, and providing data to the evaluation unit. This universal device reduces overall system complexity despite the decentralized information gathering approach.
Solution Approach 2:
The patent combines the transmitting and receiving functions into a single integrated unit on the industrial truck. This merged device handles all RFID communication tasks, reducing the number of separate components needed while maintaining reliable direct reading capability for accurate transport information.
4Adaptability or versatility
If conventional data terminals are used for central order transmission, then the system architecture is simplified, but transport processes cannot be adapted to specific goods and maximum permissible speed information is not provided
Solution Approach 1:
Transport information including destination, transport conditions, and maximum permissible speed is pre-stored on RFID transponders attached to goods and load carriers before loading. This preliminary action ensures that all necessary transport data is already available on the goods themselves, enabling immediate adaptation of transport processes without requiring additional data storage capacity during transit.

Function Achieved in This Case
This solution simplifies transport processes by enabling operators to access real-time data directly from the goods and load carriers, reducing errors and improving operational efficiency by providing immediate and accurate transport information.

AI summary
The ground conveyor (10) has an indicating device (14) for operating person and with a sending-and receiving unit (20) aligned to the load receiving area. The sending-and receiving unit receives transmitted data from load goods (24) and from load bearing (28). The evaluating processor unit verifies received data from load good with respect to terms of conveyance and represents terms of conveyance at indicating device.
