1Productivity

If autonomous construction vehicles operate without collision avoidance systems, then construction efficiency improves, but collision risk increases

Engineering Contradiction:

Improveconstruction efficiencyVSAvoidcollision avoidance

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The system performs preliminary path planning and collision zone identification before construction operations begin. The dispatch control server calculates potential collision zones in advance based on construction paths of multiple vehicles, enabling preventive control measures to be implemented before actual collisions can occur, thus maintaining both efficiency and safety.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The dispatch control server acts as an intermediary between autonomous construction vehicles and the construction site environment. It receives path information from vehicles, identifies collision zones, and sends control instructions back to vehicles, mediating the interaction to prevent collisions while maintaining construction efficiency.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Measurement precision

If construction paths are divided into multiple sections for detailed analysis, then collision detection accuracy improves, but system complexity increases

Engineering Contradiction:

Improvecollision zone identification accuracyVSAvoidpath analysis complexity

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The system segments construction paths into multiple sections to enable detailed collision analysis in each segment. By dividing the continuous path into discrete sections, the system can identify collision zones with higher precision while managing computational complexity through structured segmentation rather than analyzing the entire path as one continuous segment.

Inventive Principle:

Principle #1Segmentation

AI summary

A method includes generating a construction path for the autonomous construction vehicle and at least one other vehicle. The method also includes identifying at least one possible collision zone in the construction path. The method also includes, in response to identifying the at least one possible collision zone: dividing the construction path into one or more sections; determining all possible collision combinations; and identifying one or more collision zones based on the possible collision combinations. The method also includes selectively controlling, using data from one or more sensors associated with one or more of the autonomous construction vehicle and the at least one other vehicle associated with the construction site, at least the autonomous construction vehicle based on the possible collision zones.
