Telescopic Aircraft Cargo Loader with Articulated Boom
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional material handling equipment with a high arc movement restricts the ability to load or unload cargo from aircraft like the C-130, requiring additional equipment and increasing costs and time, as it cannot operate within the aircraft's dimensions without external assistance.
Innovation Solution
A rotatable and articulated material handling apparatus with telescopic riser, boom, and jib portions, coupled with a control system, allowing independent selective movement in a push-pull mode, enabling the apparatus to be mounted on a vehicle and extend into an aircraft cargo space for efficient loading and unloading without additional equipment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional L-shaped hooked arm equipment is used, then the equipment structure is simple, but it cannot load or unload aircraft like C-130 without additional equipment
Solution Approach 1:
The material handling apparatus is divided into multiple telescopic segments (riser portion, boom portion, jib portion) that can independently extend and retract. This segmentation allows the apparatus to achieve complex motion paths and reach into aircraft cargo spaces while maintaining a compact stowed configuration, resolving the contradiction between adaptability and device complexity.
Solution Approach 2:
The apparatus incorporates multiple degrees of freedom with rotatable assemblies and articulated joints that allow dynamic adjustment of the arm configuration. This enables the system to adapt its shape and reach to match different loading scenarios, including accessing aircraft cargo compartments, while maintaining structural efficiency.
2Productivity
If high arc movement is used, then the equipment structure is simple, but it requires additional equipment and increases time and costs
Solution Approach 1:
The apparatus transitions from conventional two-dimensional high arc movement to three-dimensional motion by adding vertical telescopic extension capability. The riser portion extends upward to clear aircraft roof contours, while the boom and jib portions reach horizontally into the cargo space, enabling direct loading without external equipment.
Solution Approach 2:
The telescopic boom apparatus is designed to perform multiple functions: it can load standard containers, access aircraft cargo spaces, operate in confined areas, and work with various container types. This multi-functionality eliminates the need for specialized equipment for different loading scenarios, improving productivity while maintaining reasonable device complexity.
3Adaptability or versatility
If telescopic portions are independently moved in push-pull mode, then the apparatus can operate within aircraft constraints, but the control system becomes more complex
Solution Approach 1:
The control system incorporates feedback mechanisms that monitor the position and status of each telescopic portion, allowing coordinated movement and preventing over-extension or mechanical interference. This feedback control enables the complex multi-degree-of-freedom system to operate reliably within the confined and constrained environment of aircraft cargo spaces.
