Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If conventional off-road vehicle control systems use fixed perception zones, then the system complexity is low, but the adaptability to changing vehicle and environmental parameters deteriorates

Engineering Contradiction:

Improveadaptability to vehicle and environmental parametersVSAvoidsystem complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements dynamic perception zones that automatically adjust their boundaries and characteristics based on real-time vehicle parameters (mass, center of gravity, component health) and environmental conditions (ground surface, weather, visibility). This transforms the static perception zone into a dynamic adaptive system that responds to changing operating conditions without requiring manual intervention or complex reconfiguration.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system changes key parameters of the perception zone (size, shape, sensitivity thresholds) based on input parameters such as vehicle mass, component health status, ground cornering stiffness, and environmental conditions. This allows the perception zone to adapt its characteristics to match the current operational context, improving versatility while maintaining manageable system complexity through parameter-based adaptation.

Inventive Principle:

Principle #35Parameter changes

2Adaptability or versatility

If dynamic perception zones are implemented with multiple parameters, then the adaptability improves, but the measurement precision requirements increase

Engineering Contradiction:

Improvedynamic adaptation capabilityVSAvoidparameter measurement precision

Core Design Contradiction:

Adaptability or versatilityVSMeasurement precision

Solution Approach 1:

The system incorporates feedback mechanisms that continuously monitor vehicle parameters (mass, center of gravity position, component health) and environmental conditions (ground surface characteristics, weather, ambient visibility). This feedback loop enables real-time adjustments to the perception zone boundaries and characteristics, ensuring accurate adaptation while managing measurement precision requirements through continuous validation and adjustment.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The system performs preliminary assessments of vehicle and environmental parameters before generating the perception zone. By pre-evaluating factors such as vehicle mass, component health status, and ground conditions, the system can proactively configure appropriate perception zone parameters, reducing the need for high-precision real-time measurements during critical obstacle avoidance scenarios.

Inventive Principle:

Principle #10Preliminary action

3Productivity

If autonomous obstacle avoidance is implemented, then the productivity increases, but the reliability requirements increase

Engineering Contradiction:

Improveoperational efficiencyVSAvoidobstacle avoidance reliability

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The autonomous obstacle avoidance system dynamically adjusts the perception zone based on real-time vehicle and environmental parameters, enabling reliable autonomous operation across diverse off-road conditions. The dynamic adaptation ensures that the perception zone remains appropriate for the current operational context, maintaining high reliability while enabling continuous autonomous productivity without manual intervention.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system performs self-service by autonomously monitoring its own operational parameters and environmental conditions, then automatically adjusting the perception zone and obstacle avoidance behavior accordingly. This self-adjusting capability enables reliable autonomous operation, as the system can independently respond to changing conditions without external intervention, thereby maintaining both productivity and reliability.

Inventive Principle:

Principle #25Self-service
