Thruster Battery Module for Suspended Load Motion Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for controlling suspended loads, such as those lifted by helicopters or cranes, face challenges in managing unstable motion like yaw, pendular motion, and horizontal translation, which can lead to hazardous conditions and operational delays due to their reliance on carrier-based countermeasures that are inadequate and costly.
Innovation Solution
A suspended load control system (SLCS) that includes thrusters and a battery module, securely attached to the load or its holding structure, uses vector thrust forces to independently control the load's motion, including yaw and horizontal translation, allowing for precise positioning and obstacle avoidance.

Engineering Contradiction Analysis
1Reliability
If carrier-based countermeasures are used to control suspended load motion, then the load can be controlled, but the system becomes costly and inadequate
Solution Approach 1:
The invention extracts the load control function from the carrier system and implements it independently on the load itself through the SLCS. The thrusters and battery module are mounted directly on the load, enabling autonomous control of yaw, pendular motion, and horizontal translation without relying on complex carrier-based countermeasures.
Solution Approach 2:
The SLCS acts as an intermediary system between the load and the carrier, providing independent motion control. The thrusters generate forces that directly affect the load's motion, while the battery module provides the necessary power, serving as a self-contained control system that mediates between the load and external environmental forces.
2Productivity
If traditional hoist systems are used, then loads can be suspended, but unstable motion causes hazardous conditions and operational delays
Solution Approach 1:
The SLCS applies preliminary anti-action by using thrusters to counteract unstable motion forces before they can cause hazardous conditions. The system continuously generates compensating forces to oppose yaw, pendular motion, and horizontal translation, preventing these harmful motions from developing into dangerous conditions that would delay operations.
Solution Approach 2:
The system employs feedback control where sensors detect the load's motion state and the control system adjusts thruster output accordingly. This closed-loop control continuously monitors and corrects unstable motion, maintaining load stability and preventing hazardous conditions while improving operational efficiency.
