Forklift Optical Markings for Flexible Intralogistics Area Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing intralogistics systems for industrial trucks require high initial investments and are inflexible, relying on expensive stationary components that are proprietary and difficult to modify or expand, limiting their adaptability to changing operating conditions.
Innovation Solution
The method involves using variable markings detectable by an optical sensor, such as cameras, that can be manually or centrally controlled to transmit different messages to the industrial truck, allowing for flexible and cost-effective operation without the need for extensive infrastructure or power supply, enabling operators to easily change or add features and instructions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If stationary components (transmitters/receivers) are used to enable vehicle responses in defined areas, then safety and control functions are improved, but initial investment costs and device complexity increase significantly
Solution Approach 1:
The patent replaces expensive stationary transmitters/receivers with simple visual markings (copies of information) that can be detected by optical sensors. Instead of installing complex communication infrastructure, the system uses marked areas with printed information that replicate the functional purpose of electronic transmitters, thereby reducing device complexity while maintaining safety functions
Solution Approach 2:
The patent employs inexpensive markings (such as printed signs, colored floor markings, or stickers) instead of expensive stationary electronic components. These markings are cheap to produce and replace, requiring minimal infrastructure investment while achieving the same safety and control objectives
2Adaptability or versatility
If stationary components are installed to trigger vehicle responses, then area control capability is improved, but flexibility and ease of modification deteriorate
Solution Approach 1:
The patent enables dynamic reconfiguration of controlled areas by simply changing or relocating markings rather than reconfiguring fixed electronic infrastructure. Markings can be easily added, removed, or modified to adapt to changing operational requirements, providing flexibility while maintaining area control capability
Solution Approach 2:
The patent divides the operating area into multiple marked zones with specific instructions, allowing independent control and modification of individual areas. This segmentation enables flexible adjustment of specific zones without affecting the entire system, improving both adaptability and ease of modification
3Reliability
If multiple stationary components are deployed for comprehensive area monitoring, then coverage and safety are improved, but cost and installation complexity increase
Solution Approach 1:
The patent uses a single optical sensor on the vehicle that can detect multiple different markings and respond accordingly. This universal detection capability replaces the need for multiple specialized stationary transmitters, reducing the quantity of components while maintaining comprehensive safety coverage across different areas

AI summary
The invention relates to a method for operating a forklift truck (F) with at least one optical sensor (C1, C2, C3) for detecting information in the operating area of the forklift truck (F) and a data processing device (VC) for evaluating this information and for generating situation-appropriate instructions and/or control commands for the operation of the forklift truck (F), as well as a forklift truck for carrying out the method and an intralogistics system with at least one such forklift truck.The optical sensor (C1, C2, C3) detects at least one marking (1, 2, 3) placed in the operating area of the industrial truck (F), which contains information encoded with defined messages to the industrial truck (F), wherein the messages can be actively changed by an operator and/or a control system, and the data processing unit (VC) creates the instructions for action and/or control commands by evaluating these messages.
