Innovation Solution
A method utilizing a sensor unit with at least two sensors on the working tool to detect physical variables, storing data in a memory unit, and communicating wirelessly via Bluetooth to a control unit, enabling cost-effective and simple data exchange, even with tools lacking bus systems or separate sensors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a bus system with physical connections is used for data transmission between the working vehicle and working tool, then direct and reliable data communication is achieved, but compatibility problems arise due to different combination standards and additional physical connection expenditure is required
Solution Approach 1:
The patent replaces the mechanical bus system connection with a wireless communication system. The working tool is equipped with a sensor unit that communicates data wirelessly to the working vehicle's control unit, eliminating the need for physical connection lines and thereby resolving compatibility issues between different manufacturers while maintaining reliable data transmission.
2Loss of information
If a bus system with physical connections is installed between working vehicle and working tool, then data transmission is established, but additional physical connection expenditure and installation complexity increase
Solution Approach 1:
The patent eliminates the need for physical connection lines by implementing wireless communication between the sensor unit on the working tool and the control unit on the working vehicle. This substitution reduces installation costs and complexity while ensuring complete transmission of operating data.
3Ease of operation
If the operator manually controls driving speed based on subjective impressions, then flexibility in adapting to soil conditions is achieved, but precision and efficiency of field working are reduced
Solution Approach 1:
The patent implements a feedback system where the sensor unit continuously monitors operating conditions and soil parameters, and the control unit automatically adjusts the driving speed based on this feedback data. This maintains operator flexibility while significantly improving driving speed precision and overall field working efficiency.
4Device complexity
If working tools without bus systems or separate sensors are used, then cost and complexity of the tool are reduced, but data detection and transmission capabilities are limited
Solution Approach 1:
The patent introduces a wireless sensor unit as an intermediary component on the working tool. This sensor unit detects operating data and transmits it wirelessly to the control unit on the working vehicle, enabling data collection and transmission capabilities in tools that would otherwise lack such systems, without significantly increasing tool complexity.

AI summary
A method is provided for operating a system consisting of an agricultural working vehicle, at least one working tool arranged thereon, and a controller assigned to the working vehicle. The method includes detecting, by at least one sensor assembly arranged at least on the working tool and having at least two sensors, two different physical variables. The method further includes storing, by a memory, information characterizing the working tool, continuously storing, by the memory, operating data of at least the working tool, and communicating wirelessly via Bluetooth network with the controller by the at least one sensor assembly via a transmitter. The controller is brought into a transmission range of the sensor assembly to activate the communication between them and the operating data temporarily stored in the memory is transmitted to the controller.
