Additive Construction Zone Readiness Controller
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing additive construction control systems lack adequate evaluation of worksite conditions before construction, leading to insufficient worksite planning and potential safety and effectiveness issues during structure construction.
Innovation Solution
A system comprising a positioning system with perception sensors, a memory for storing additive construction plans, and a controller that determines a construction zone based on topographical characteristics, identifying impediments and ensuring the zone is ready for execution of toolpath instructions, using a machine with actuators to position the implement according to the plan.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing additive construction control systems are used without worksite evaluation, then construction operations can proceed quickly, but worksite planning accuracy and safety are insufficient
Solution Approach 1:
The system performs preliminary worksite evaluation and identification of construction zones before actual additive construction operations begin. The controller evaluates topographical characteristics, identifies impediments, and determines suitable construction zones in advance, ensuring proper planning and safety before construction starts.
Solution Approach 2:
The control system automatically evaluates worksite conditions using perception sensors and autonomously determines construction zones and impediments without requiring manual inspection. The system serves itself by integrating worksite evaluation functionality into the existing control architecture.
2Manufacturing precision
If machine-associated actuators are used for controlling implement position, then control flexibility is improved, but control accuracy for additive construction is insufficient
Solution Approach 1:
The system introduces an intermediary worksite evaluation layer between the control system and construction operations. The controller acts as a mediator that processes topographical data, identifies impediments, and determines construction zones before executing toolpath instructions, thereby improving positioning accuracy without directly modifying the actuator mechanism.

AI summary
A system for preparing a worksite for an additive construction operation includes a positioning system configured to determine positioning signals including topographical characteristics of the worksite. An additive construction plan includes, at least, structure placement data, configured for a desired location for constructing the structure, and toolpath instructions for guiding the implement to construct the structure. A controller is configured to determine a construction zone on the worksite based on the structure placement data and the topographical characteristics of the worksite. The controller is further configured for determining if the construction zone is readied for execution of the toolpath instructions at the construction zone and, if the construction zone is not readied for such execution, identifying one or more impediments to construction at the worksite, within the construction zone, based on the topographical characteristics of the worksite.
