Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If the autonomous driving system processes all object information in high calculation mode, then the object recognition accuracy is improved, but the system becomes unstable and may halt due to overload

Engineering Contradiction:
Improveobject recognition accuracyVSAvoidsystem stability
Core Design Contradiction:
Measurement precisionVSReliability

Solution Approach 1:

The patent applies local quality by differentiating calculation modes for different objects based on their priority levels. High-priority objects (those with higher collision risk) are processed in high calculation mode to maintain recognition accuracy, while low-priority objects are processed in low calculation mode to reduce overall system load. This selective approach ensures critical objects receive full processing resources while preventing system overload.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The system dynamically changes the calculation mode parameter based on real-time assessment of object priority, frame complexity, and resource occupation state. By adjusting the calculation mode (high, low, or skip) as a variable parameter rather than maintaining a fixed high calculation mode, the system achieves both accurate recognition of critical objects and overall system stability.

Inventive Principle:
Principle #35Parameter changes

2Measurement precision

If the autonomous driving system maintains high calculation processing for all frames, then the object recognition precision is improved, but the processing speed decreases due to resource constraints

Engineering Contradiction:
Improveobject recognition precisionVSAvoidprocessing speed
Core Design Contradiction:
Measurement precisionVSProductivity

Solution Approach 1:

The patent implements local quality by applying different calculation modes to different objects within the same frame based on their priority assessment. High-priority objects undergo intensive high calculation mode processing for precise recognition, while low-priority objects receive simplified low calculation mode processing. This differential approach maintains high recognition precision for critical objects while significantly improving overall processing throughput.

Inventive Principle:
Principle #3Local quality

3Quantity of substance

If the autonomous driving system processes complex frames with many objects, then the comprehensive object detection is improved, but the system resource occupation increases leading to overload

Engineering Contradiction:
Improvenumber of detected objectsVSAvoidsystem resource consumption
Core Design Contradiction:
Quantity of substanceVSUse of energy by moving object

Solution Approach 1:

The patent applies local quality by assessing each object's priority independently within complex frames and assigning appropriate calculation modes. This allows the system to detect and track all objects (maintaining quantity) while consuming fewer computational resources by processing only high-priority objects in high calculation mode and low-priority objects in low calculation mode.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The system applies partial action by selectively providing high calculation mode processing only to the extent necessary for high-priority objects, rather than uniformly applying high calculation to all objects. This partial intensive processing approach maintains comprehensive object detection while preventing excessive resource consumption that would lead to system overload.

Inventive Principle:
Principle #16Partial or excessive action
