Carrying Arm Structure for Simultaneous Lift and Cargo Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing carrying devices have low efficiency due to the sequential processes of vertical lifting and vehicular movement, which results in inefficient object transfer between the device and the vehicular body.
Innovation Solution
A carrying device with a carrying arm that can horizontally protrude and retract into the vehicular body, utilizing a lift mechanism and a suspension auxiliary mechanism with support wheels and climb guide components, allowing simultaneous vertical and horizontal displacement during lifting, and suspension from the ground to reduce friction.

Engineering Contradiction Analysis
1Productivity
If the carrying arm protrudes to lift object vertically upward and then the vehicular body travels forward, then the object can be transferred onto the vehicular body, but the carrying efficiency is low due to sequential processes
Solution Approach 1:
The patent merges the vertical lifting function and horizontal transfer function into a single integrated carrying arm structure. The carrying arm simultaneously performs vertical protrusion to lift the object and horizontal retraction to transfer the object onto the vehicular body, combining two sequential operations into one concurrent action, thereby improving carrying efficiency and reducing transfer time.
Solution Approach 2:
The carrying arm is designed with dynamic motion capabilities, allowing it to protrude vertically and retract horizontally in a coordinated manner. This dynamic structure enables the carrying arm to adapt its position and orientation during the lifting and transfer process, optimizing the transfer trajectory and reducing the time required for object transfer while maintaining high carrying efficiency.
2Speed
If the support wheel contacts the ground during carrying operation, then the carrying arm can be supported, but friction with the ground reduces travel speed
Solution Approach 1:
The support wheel is designed to be dynamically adjustable, capable of being raised above the ground during travel and lowered to contact the ground during carrying operations. This dynamic positioning allows the system to eliminate ground friction during travel by suspending the support wheel, thereby increasing travel speed, while still providing necessary support during carrying tasks when the wheel is lowered.
Solution Approach 2:
Before the vehicular body begins travel, the support wheel is raised to a suspended position in advance to prevent ground contact and friction. This preliminary action ensures that the support wheel does not contact the ground during travel, eliminating frictional resistance and enabling faster travel, while the support wheel can be lowered when carrying operations are required.

AI summary
A carrying device and a method for carrying an object are provided. The carrying device includes a vehicular body (20) and a carrying arm (30) disposed in the vehicular body (20). The carrying arm (30) includes an arm body (301) on which a lift mechanism (303) is disposed. The carrying arm (30) can horizontally protrude from the vehicular body (20) to lift object through the lift mechanism (303) and retract into the vehicular body (20). When the lift mechanism (303) lifts from a low level to a high level, the top part of the lift mechanism (303) horizontally moves along a direction in which the carrying arm (30) retracts into the vehicular body (20).
