Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If autonomous agricultural machines operate without human operators, then productivity and cost-effectiveness are improved, but control over work quality and safety is lost
Solution Approach 1:
The patent implements a feedback system where sensors on the autonomous machine continuously monitor work parameters and transmit data to the user's terminal. The system compares actual work quality against target values and provides real-time feedback, allowing users to verify and control work quality remotely without being physically present on the field.
Solution Approach 2:
The patent introduces a communication system as an intermediary between the autonomous machine and the user. This intermediary transmits work data, target values, and quality metrics through electronic communication channels, enabling the user to maintain control over work quality without direct physical presence or manual operation of the machine.
2Reliability
If operators remain in close proximity to autonomous machines for remote control, then work quality control is improved, but the autonomy and cost-effectiveness are reduced
Solution Approach 1:
The patent introduces a communication system as an intermediary between the autonomous machine and the user. This intermediary transmits work data, target values, and quality metrics through electronic communication channels, enabling the user to maintain control over work quality without direct physical presence or manual operation of the machine.
Solution Approach 2:
The patent replaces the mechanical system of physical presence and manual remote control with an electronic information system. Instead of operators needing to be physically near machines to monitor and control them, the system uses electronic data transmission and processing to achieve the same control functions from a distance, thereby increasing autonomy.
3Manufacturing precision
If target data and limit values are continuously monitored, then work quality is improved, but system complexity increases
Solution Approach 1:
The patent implements a multi-functional communication terminal that serves multiple purposes: receiving work data from sensors, comparing data against target values, generating quality assessments, and providing feedback to the user. This universal terminal consolidates multiple functions into a single device, reducing overall system complexity while maintaining comprehensive work quality monitoring.

AI summary
The invention relates to an assistance system (1) based on electronic data exchange (11) for enabling an autonomous vehicle (2) to act as an autonomous agricultural machine (3) and to execute an operational plan (55) specified by a client (57), wherein the operational plan (55) includes target data (78) and the assistance system (1) is configured to guarantee the success of the operational plan (55) by extracting the target data (78) from the operational plan (55), assigning target limit values (80) to the extracted target data (78), determining the actual limit values of the target data (78) and the deviation of these actual limit values (82) from the defined target limit values (80), and initiating measures (84a..n) if a target limit value (80) is exceeded or not reached, which determine the respective actual limit value. (82) within the range of the defined target limit value (80).
