Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Automated Guided Vehicles (AGVs) in aircraft manufacturing facilities face the risk of tipping over due to uneven weight distribution of loads, potentially causing damage to both the load and the AGV.
Innovation Solution
An AGV equipped with a balancing plate, load sensors, and an actuator system that shifts the plate laterally to align the load's center of gravity with the AGV's center of gravity, ensuring stable transport through facilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the AGV carries a load with uneven weight distribution, then the AGV can transport the load, but the AGV is at risk of tipping over
Solution Approach 1:
The balancing plate is made movable rather than fixed, allowing it to shift laterally in response to weight distribution variations. The actuator dynamically adjusts the plate position to compensate for uneven loads, transforming a static structure into a dynamic one that adapts to changing conditions to prevent tipping
Solution Approach 2:
Load sensors continuously detect the weight distribution on the balancing plate and provide feedback to the control system. The controller processes this information and commands the actuator to adjust the plate position accordingly, creating a closed-loop feedback system that maintains stability by constantly monitoring and responding to load conditions
2Reliability
If the balancing plate is added to the AGV, then the tipping risk is reduced, but the device complexity increases
Solution Approach 1:
The AGV system is segmented into distinct functional modules: the balancing plate as a separate movable component, load sensors as independent detection elements, an actuator as a dedicated adjustment mechanism, and a control system as a separate brain. This segmentation allows each component to perform its specific function efficiently and simplifies the overall system design and maintenance
Solution Approach 2:
The balancing plate acts as an intermediary element between the load and the AGV chassis. It provides a interface that allows the load to be positioned independently of the vehicle body, enabling weight distribution adjustment without directly modifying the AGV's structural components or control systems
3Reliability
If the balancing plate shifts laterally, then the center of gravity alignment is improved, but the manufacturing precision requirements increase
Solution Approach 1:
The system uses self-service principles where the load sensors automatically detect weight distribution imbalances and the control system autonomously commands the actuator to adjust the balancing plate position. This self-regulating mechanism eliminates the need for manual precision alignment during manufacturing, as the system automatically compensates for positioning variations through active control
Solution Approach 2:
The system changes the position parameter of the balancing plate dynamically based on detected weight distribution. By allowing the plate to move laterally over a range of positions rather than requiring a single fixed precise position, the system transforms a static precision requirement into a dynamic adjustment capability, reducing manufacturing precision demands

AI summary
Systems and methods for an Automated Guided Vehicle (AGV) capable of automatically balancing large and heavy objects for transport through a facility. One embodiment is an Automated Guided Vehicle (AGV) including a balancing plate configured to support a load, load sensors configured to detect a weight distribution of the load, and an actuator configured to shift the balancing plate laterally. The AGV also includes a weight balancing controller configured to determine a center of gravity of the load based on the weight distribution detected by the load sensors, to determine that the center of gravity of the load is vertically misaligned with a center of gravity of the AGV, and to direct the actuator to shift the balancing plate laterally to move the center of gravity of the load toward vertical alignment with the center of gravity of the AGV.
