Work Flight Vehicle Holder Adjustment for Suspended-Object Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing work devices for flight vehicles, such as drones, face instability during transportation of objects due to swinging, leading to detachment and inability to reach the destination for work, and require time-consuming collection.
Innovation Solution
A work device with adjustable holders and a controller that counteracts swinging of the object by adjusting the posture of the holders, generating tension, and using swing detectors and movement mechanisms to stabilize the object during flight.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the drone uses a cutting blade to cut the wire rope when flight is unstable, then the drone weight is reduced and safe flight is maintained, but the object cannot be transported to the destination and work cannot be performed
Solution Approach 1:
The invention extracts the harmful swinging motion from the system by using active posture adjustment of holders, rather than simply cutting the connection. The adjustment mechanism removes the instability while preserving the connection, allowing both flight safety and transportation capability to coexist
Solution Approach 2:
The invention changes the posture parameters of the holders dynamically to counteract swinging. By adjusting the posture of holders based on detected swing conditions, the system maintains stable object suspension without needing to cut the wire rope, thus preserving transportation capability while ensuring flight safety
2Stability of the object's composition
If the drone detaches the object to stabilize flight, then flight stability is improved, but the object cannot reach the destination for work and collection becomes time-consuming
Solution Approach 1:
The invention makes the holder postures dynamic and adjustable rather than fixed. The adjustment mechanism allows real-time modification of holder configurations to actively counteract swinging during flight, maintaining stability without detachment and eliminating the need for time-consuming collection operations
Solution Approach 2:
The invention implements a feedback control system where swing detection triggers automatic posture adjustment of holders. This closed-loop control maintains flight stability continuously, preventing the need to detach objects and eliminating collection time losses
3Productivity
If the holder posture is adjusted to counteract swinging, then stable work is enabled, but the device complexity increases
Solution Approach 1:
The invention divides the stabilization function into separate adjustable holder units, each capable of independent posture adjustment. This segmentation allows targeted counteraction of swinging in different directions without requiring a completely complex integrated system, achieving stable work with manageable device complexity

AI summary
A work device that is capable of suspending an object includes a plurality of holders configured to hold the object such that the object is suspended, an adjustment mechanism configured to adjust respective postures of the plurality of holders, and a controller configured or programmed to control operation of at least the adjustment mechanism and control the adjustment mechanism to change the respective postures of the holders so as to counteract swinging of the object.
