Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional construction site planning for autonomous construction vehicles is often non-automatic, inefficient, prone to user error, and limits the functionality of these vehicles.
Innovation Solution
A method and system for automatically recording a construction site boundary, defining a path orientation, maneuver area, and creating a site plan that includes a work area, start point, and path for autonomous construction vehicles, enabling autonomous control based on the site plan.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If conventional construction site planning methods are used, then manual control and adjustment are possible, but the process is non-automatic, inefficient, and prone to user error
Solution Approach 1:
The autonomous construction vehicle automatically creates its own site plan using onboard sensors and processors to record boundaries, define maneuver areas, generate paths, and orient itself without external human intervention or complex external planning systems
Solution Approach 2:
Manual mechanical planning processes are replaced with electronic sensing, computational algorithms, and automated control systems that process spatial data and generate navigation paths programmatically
2Productivity
If conventional site planning is used, then flexibility in manual adjustment exists, but productivity is reduced and human resources are required
Solution Approach 1:
The vehicle performs preliminary actions by automatically recording boundaries, defining maneuver areas, and calculating optimal paths before commencing construction work, eliminating the need for separate manual planning phases and enabling immediate productive operation
Solution Approach 2:
The automated planning system enables continuous productive operation by eliminating idle manual planning time, allowing the vehicle to transition seamlessly from boundary recording to path execution without human intervention delays
3Reliability
If manual site planning is used, then user control is maintained, but user error and functional limitations occur
Solution Approach 1:
The vehicle continuously monitors its position, orientation, and surroundings using sensors, comparing actual state with planned path, and automatically adjusts navigation to maintain accuracy and avoid errors that would occur with manual operation

AI summary
A method for controlling an autonomous construction vehicle may include defining a boundary of a construction site and automatically creating a site plan for navigating the autonomous construction vehicle within the boundary. The site plan includes a work area within the boundary, a maneuver area positioned between the work area and the boundary, a start point for the autonomous construction vehicle, and a path for the autonomous construction vehicle. A controller can then provide the site plan for review and activate autonomy mode to automatically control the autonomous construction vehicle according to the site plan.
