Rotatable Arm Crane Mechanism for Simplified Multi-Direction Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional small crane machines designed for children are cumbersome to operate due to the complexity of controlling movements in three directions, which hinders their popularity and ease of use.
Innovation Solution
A crane machine with a rotatable arm that allows simultaneous movement in vertical, front, and back directions using a single driving mechanism, simplifying the control method and reducing operational difficulty by integrating a rotation drive assembly and elevation drive assembly with a gripper system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional crane machine controls movement in three directions (up and down, left and right, front and back), then the crane machine can grab and transport items effectively, but the operation becomes cumbersome and difficult for children
Solution Approach 1:
The patent merges the control of multiple movement directions into a single rotatable arm mechanism. The arm can rotate to change the gripper's position in front-back and left-right directions simultaneously, while the elevation mechanism handles up-down movement. This integration reduces the number of independent controls from three to two, simplifying operation for children.
Solution Approach 2:
The rotatable arm serves multiple functions: it positions the gripper in the front-back direction, adjusts left-right position, and works in conjunction with the elevation mechanism for comprehensive movement control. This multi-functionality reduces the need for separate control mechanisms for each direction.
2Adaptability or versatility
If the crane machine is designed to be small and mainly for children, then it is more accessible, but the three-direction control becomes even more cumbersome and difficult
Solution Approach 1:
The patent combines multiple control functions into fewer mechanisms, making the small crane machine easier to operate for children. The rotatable arm integrates front-back and left-right positioning, reducing the cognitive load and physical complexity for young users while maintaining the machine's compact size and accessibility.
3Device complexity
If the gripper rotates around a vertical centerline, then it can move in front-back and left-right directions simultaneously with a single driving member, but the mechanism must handle complex rotational movement
Solution Approach 1:
The patent introduces rotational movement around a vertical centerline as a new dimension of control. Instead of controlling front-back and left-right movements separately through linear mechanisms, the system uses rotational transformation, where a single rotation of the arm simultaneously changes both positional coordinates, simplifying the driving mechanism while maintaining versatile movement capability.

AI summary
The present disclosure provides a crane machine having a rotatable arm, including: a main body, the rotatable arm, a rotation drive assembly, an elevation drive assembly, and a gripper. The main body defines a holding cavity and a conveying channel; wherein the conveying channel includes an opening that is in communication with the holding cavity. The rotatable arm is arranged in the holding cavity. The rotation drive assembly includes a first driving member configured to drive the rotatable arm to rotate around the centerline. The elevation drive assembly is arranged in the rotatable arm and includes a second driving member and a rotation wheel. The gripper is connected to the rotation wheel through a connection rope; the opening is disposed on a rotational radius of the gripper.
