Load Handling Arm Structure for Compact 360° Cargo Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cargo handling methods, such as using forklifts, are inefficient when forklifts are not available, and integrated cargo handling devices are either bulky or heavy, reducing transport efficiency and space utilization.
Innovation Solution
A load handling device with a holding arm, support frame, and rotation structures, including a disk rotation unit, allows for efficient loading and unloading by minimizing device size and weight, and enabling 360-degree rotations and telescopic movements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional forklift is used for cargo handling, then loading and unloading can be performed, but the device is bulky and heavy, reducing transport efficiency and space utilization
Solution Approach 1:
The holding arm is divided into multiple segments (first arm part, second arm part, third arm part) that can move relative to each other, allowing the device to achieve forklift functionality without requiring a single bulky structure. This segmentation enables compact folding when not in use while maintaining full operational capability.
Solution Approach 2:
The device transitions from a static bulky structure to a dynamic compact system through multiple rotation structures and telescopic mechanisms. The holding arm can extend to full length during operation and fold into a compact configuration during transport, optimizing both operational capability and space utilization.
2Productivity
If an integrated cargo handling device is installed in the transportation unit, then loading and unloading efficiency improves, but the device size and weight increase, reducing effective load capacity
Solution Approach 1:
The holding arm segments are designed to nest within each other when retracted, with the second arm part fitting within the first and the third within the second. This nesting arrangement minimizes the device footprint and weight while maintaining full operational capability when extended.
Solution Approach 2:
The device employs dynamic extension and retraction mechanisms that allow it to achieve full forklift dimensions during loading/unloading operations, then collapse to a minimal profile during transport, maximizing effective load capacity at all times.
3Stability of the object's composition
If a stable disk suspension structure is used for the loading device, then structural stability is achieved, but the construction becomes big and heavy
Solution Approach 1:
The rotation structures are divided into multiple independent rotational joints rather than relying on a single large disk suspension. Each joint provides necessary stability for its specific segment while maintaining overall structural integrity, allowing compact dimensions.
Solution Approach 2:
The device achieves stability through multi-dimensional rotation capabilities rather than a single large suspension disk. Multiple rotation axes and telescopic dimensions provide structural stability while maintaining compact overall volume.

AI summary
A device for load handling can be installed in a transportation unit. The device comprises a holding arm, a support frame and a first rotation structure. The holding arm comprises a horizontal arm part, a vertical arm part and a handling head. The support frame comprises a first support frame side and a second support frame side. The second support frame side comprises a first end of the second support frame side and a second end of the second support frame side. The first rotation structure comprises a disk rotation unit for rotating the horizontal arm part. The diameter of the rotation unit is less than half of the length of the second support frame side, and the rotation unit is positioned nearer to the first support frame side than to the first end of the second support frame side.
