Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional jacking devices have complex structure assemblies and operation conditions, making them difficult to use for assisting objects or machine bodies in motion and limiting their application range.
Innovation Solution
A jacking device comprising a slave arm and a link arm with an elastic device, where the slave arm's first end can rotate and move linearly, pushing the link arm to change positions and assist in object rotation and movement, with the elastic device storing and releasing energy to return to initial positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional jacking devices use complex structure assemblies, then lifting function is achieved, but ease of operation deteriorates and device complexity increases
Solution Approach 1:
The jacking device is divided into distinct functional segments: a slave arm with first and second ends, a link arm with fixation end and free end, and an elastic device. Each segment performs a specific function, allowing the complex lifting operation to be broken down into simpler, more manageable parts that are easier to operate and understand.
Solution Approach 2:
The device employs dynamic components including the slave arm that can rotate and move linearly, the link arm that rotates about the fixation end, and the elastic device that stores and releases energy. These dynamic elements replace static complex mechanisms, enabling smoother operation and reducing assembly complexity while maintaining lifting functionality.
2Adaptability or versatility
If conventional jacking devices have complex structure assemblies, then lifting function is achieved, but adaptability to different objects deteriorates
Solution Approach 1:
The jacking device is designed with universal application capability through its modular structure. The slave arm can be connected to different machine bodies or objects, and the link arm can push various objects for rotation and upward or downward movement. This multi-functional design allows the same device structure to assist different objects in producing various motions, significantly expanding application range without increasing complexity.
3Ease of operation
If elastic device is added to store and release energy, then motion assistance is enhanced, but device complexity increases
Solution Approach 1:
The elastic device is configured to automatically store energy when the slave arm moves in response to applied force, and automatically release this energy to return the slave arm and link arm to their initial positions when the force is removed. This self-service mechanism enhances motion assistance by providing automatic return motion without requiring additional complex control systems or manual intervention.
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 structure assembly, enhances motion assistance for objects and machine bodies, and expands application range by providing a labor-saving mechanism for rotation and upward/downward movements.
Implementation Method 1
an elastic device is configured between the first end of the slave arm and the fixation end of the link arm. The elastic device stores energy therein when the first end of the slave arm is motioned in response to the applied action force

AI summary
A jacking device is provided to push an object for rotation and upward or downward movement. The jacking device includes a combination of a slave arm and a link arm. The slave arm includes a first end capable of producing rotation and linear movement and a second end pivoted to the link arm. The link arm includes a fixation end disposed on a base and a free end. When the first end of the slave arm is received with an action force, the second end of the slave arm is forced to push the link arm for rotation, and the free end of the link arm is forced to motion between a first position and a second position so as to push an object for rotation and upward or downward movement.
