Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If the driver manually positions the vehicle precisely at the target position and orientation during the recording process, then the automated maneuvering can accurately reproduce the route, but the operation becomes time-consuming and inconvenient

Engineering Contradiction:

Improvepositioning accuracyVSAvoiddriver convenience

Core Design Contradiction:

Manufacturing precisionVSEase of operation

Solution Approach 1:

The system automatically detects the target position and orientation using sensors and processing units, eliminating the need for the driver to manually align the vehicle precisely. The driver assistance system performs the positioning task itself by detecting characteristic features in the surroundings and calculating the optimal target position and orientation automatically.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The manual mechanical alignment process is replaced by an automated detection and calculation system. The system uses sensor data (cameras, LIDAR, GPS) and computational algorithms to determine the target position and orientation, substituting the driver's manual positioning actions with an automated electronic system.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Measurement precision

If the system requires precise manual alignment during recording, then the repetition process can achieve accurate target positioning, but the overall process efficiency decreases

Engineering Contradiction:

Improvetarget position accuracyVSAvoidprocess efficiency

Core Design Contradiction:

Measurement precisionVSProductivity

Solution Approach 1:

The system performs target position and orientation detection during the recording phase, storing this information for later use. By detecting and storing the optimal target parameters in advance, the system eliminates the need for repeated manual alignment operations, improving efficiency in subsequent repetition processes while maintaining accuracy.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system uses sensor feedback to continuously monitor the vehicle's position and orientation relative to the target. During both recording and repetition processes, the system compares actual position with desired position and makes automatic adjustments, ensuring accurate target positioning without requiring precise manual intervention.

Inventive Principle:

Principle #23Feedback

3Manufacturing precision

If the driver manually approaches the charging interface with precise positioning, then the charging connection can be established accurately, but the time required for charging operations increases

Engineering Contradiction:

Solution Approach 1:

The system automatically detects the charging interface position and calculates the optimal vehicle positioning for charging connection. The driver assistance system performs the positioning task itself by detecting characteristic features of the charging station and calculating the target position and orientation that will establish the charging connection, eliminating manual alignment time.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The manual vehicle positioning process for charging is replaced by an automated detection and navigation system. The system uses sensors to detect the charging interface, computational units to calculate the optimal approach, and automated control to position the vehicle, substituting the driver's manual positioning actions with an automated electronic system that is both faster and more accurate.

AI summary

A driver assistance system for the automatic maneuvering of a motor vehicle is designed to determine a driving trajectory in a recording process based on a route which is manually driven by the driver with the motor vehicle, at the end of which the vehicle is in an actual target position with an actual target orientation, and on the basis of the previously determined driving trajectory, to maneuver the motor vehicle with at least automatic lateral guidance. The driver assistance system is characterized in that it is designed to detect, during the recording process, the existence of a desired target position and/or a desired target orientation of the motor vehicle. Alternatively, the driver assistance system receives information about a desired target position and/or a desired target orientation of the motor vehicle, via a user interface, for the correction of the actual target position or actual orientation. During the repetition process, the motor vehicle is maneuvered with at least automatic lateral guidance such that the motor vehicle assumes the desired target position or desired target orientation by the end of the repetition process.
