Crane Machine Gripper Synchronization via Movable Wheel
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional crane machines with electromagnetically controlled grippers are cumbersome to operate, particularly for user groups like small children, as they require separate control for gripper opening and closing, as well as spatial orientation, leading to poor user experience.
Innovation Solution
A crane machine design incorporating a first driving unit with a motor, transmission shaft, fixed wheel, and movable wheel, where the fixed wheel's rotation synchronizes with the movable wheel to control the gripping device's opening and closing through rope tension, allowing the lifting and lowering movement to control both functions with a single motor operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If an electromagnetic magnetic switch is used to control the gripper opening and closing separately, then the gripper can be controlled to open and close, but the control becomes cumbersome and user experience deteriorates
Solution Approach 1:
The patent combines the gripper opening/closing control with the lifting/lowering control into a single integrated system. The movable wheel serves dual functions: when it rotates relative to the fixed wheel, it controls gripper opening/closing through the movable rope; when it rotates synchronously with the fixed wheel, it controls lifting/lowering through the fixed rope. This merging eliminates the need for separate electromagnetic magnetic switch control, significantly improving ease of operation while reducing control system complexity.
Solution Approach 2:
The patent employs dynamic control where the movable wheel can operate in two distinct modes depending on the engagement state of the limiting portions. When the first limiting portion is spaced from the second limiting portion, the movable wheel rotates independently to control gripper opening/closing. When the limiting portions abut, the movable wheel rotates synchronously with the fixed wheel to control lifting/lowering. This dynamic switching allows a single component to perform multiple functions, improving user experience and simplifying operation.
2Ease of operation
If separate control is required for gripper opening/closing and spatial orientation, then precise control is achieved, but operation becomes difficult for small children
Solution Approach 1:
The movable wheel is designed as a universal control component that performs multiple functions. By rotating the movable wheel, users can control both gripper opening/closing (when limiting portions are spaced) and lifting/lowering (when limiting portions abut). This multi-functionality allows small children to operate the crane machine with a single intuitive action, greatly improving accessibility while maintaining control efficiency through the mechanical coupling of the limiting portions.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Simplifies the operation of the gripping device, enhancing user experience by allowing the opening and closing to be controlled through the same lifting movement, making it more accessible and convenient for smaller children.
Implementation Method 1
the first motor is configured to drive the first transmission shaft to rotate
Implementation Method 2
the movable wheel is configured to make the fixed rope coiled on the movable wheel by rotating, for controlling lifting and lowering of the gripping device
Implementation Method 3
the first limiting portion abuts against the second limiting portion, causing the fixed wheel to drive the movable wheel to rotate synchronously
