Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If autonomous driving technology uses existing route setting methods, then the system can operate with standard algorithms, but the accuracy of travel route for various situations deteriorates

Engineering Contradiction:
Improveroute setting accuracyVSAvoidhandling various situations
Core Design Contradiction:
Measurement precisionVSAdaptability or versatility

Solution Approach 1:

The system dynamically adjusts the range of driving control rights based on the vehicle's travel trajectory. When the trajectory deviates from the predefined route, the system adaptively modifies the autonomous driving control range, allowing the vehicle to handle various situations while maintaining route accuracy through continuous dynamic adjustment rather than static algorithms

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system changes the parameter of driving control right range based on trajectory analysis. By monitoring whether the vehicle follows the predefined route and adjusting the control rights accordingly, the system achieves both accurate route setting and adaptability to different driving situations through parameter modification

Inventive Principle:
Principle #35Parameter changes

2Measurement precision

If the system adjusts driving control rights based on travel trajectory, then route accuracy improves, but system complexity increases

Engineering Contradiction:
Improvetravel route accuracyVSAvoidcontrol system complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The system applies local quality by adjusting driving control rights specifically based on trajectory deviations rather than overhauling the entire control system. The complexity is localized to the trajectory monitoring and control range adjustment modules, while the rest of the autonomous driving system maintains its original structure, thus improving route accuracy without proportionally increasing overall system complexity

Inventive Principle:
Principle #3Local quality
