Jacking Device Link Mechanism Reduces Screen Operating Force
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional jacking devices for electric apparatuses require excessive force and complex two-stage sliding and rotating operations to position screens, making them laborious for users, especially females and children, due to inadequate support and limited operating space for rotation and upward movement.
Innovation Solution
A jacking device with a slave portion and a link portion, where the slave portion receives power from a support arm to drive the link portion between positions, enabling easier rotation and upward or downward movement of the screen, using elastic devices to store and release energy for efficient operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a support element or linkage mechanism is used to support the slide cover module, then the screen can be supported for touch-controlled operations, but a large force (greater than 4.2 kilograms) must be applied to lift the screen and linkage mechanism to the desired operation position
Solution Approach 1:
The patent introduces a jacking device with a slave portion and link portion that functions as a mechanical advantage system. The slave portion receives power from the support arm and transmits it through the link portion to lift the motion module. This mechanism provides mechanical advantage, reducing the operating force from over 4.2 kilograms to approximately 1.4 kilograms by distributing the lifting action across multiple leverage points and motion stages.
Solution Approach 2:
The patent introduces a jacking device with a slave portion and link portion that functions as a mechanical advantage system. The slave portion receives power from the support arm and transmits it through the link portion to lift the motion module. This mechanism provides mechanical advantage, reducing the operating force from over 4.2 kilograms to approximately 1.4 kilograms by distributing the lifting action across multiple leverage points and motion stages.
2Adaptability or versatility
If a slide rail and rotary component with swivel are used, then the angle of the slide module is adjustable, but a two-stage sliding and rotating operation is required to locate the screen at the user's desired operating position
Solution Approach 1:
The patent combines the sliding and rotating functions into a single integrated operation. The jacking device with the slave portion and link portion is configured to simultaneously achieve both sliding motion along the slide rail and rotation of the motion module as the user applies force to the support arm. This merged mechanism eliminates the need for separate two-stage operations while maintaining full angle adjustability.
Solution Approach 2:
The support arm is pre-configured with the jacking device mechanism that automatically performs the necessary sliding and rotating actions in the correct sequence. When the user applies force to the support arm, the slave portion and link portion are already positioned to translate this input motion into the combined sliding-rotating movement, eliminating the need for the user to manually perform separate operation stages.
3Reliability
If the pivot pattern of the support element, slide cover module and machine body module is used, then the screen can be supported, but excessive resistance is generated requiring more than 4.2 kilograms of thrust force
Solution Approach 1:
The jacking device with slave portion and link portion creates a mechanical advantage system that counteracts the resistance generated by the pivot patterns. By distributing the lifting force across multiple leverage points and using the link portion to translate motion efficiently, the system reduces the required thrust force from over 4.2 kilograms to approximately 1.4 kilograms while maintaining reliable support functionality.
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
The device significantly reduces the horizontal thrust force required, allowing for labor-saving operation and easier positioning of the screen, with the force needed decreasing from approximately 4.2 kilograms to 1.4 kilograms, enhancing usability for all users.
Implementation Method 1
an elastic device is configured between the slave portion and the link portion. When the slave portion is motioned, the elastic device stores energy therein so as to motion the free end of the link portion... when the action force applied on the first end of the slave portion is removed, the energy stored in the elastic device is released therefrom so as to drive the slave portion and the link portion back to their initial position

AI summary
A jacking device for assisting an electric apparatus with movement is operated in a labor-saving way, thereby simplifying complicated operational conditions occurred in conventional skills. The electric apparatus includes a machine body module, a motion module, and a support arm disposed between the motion module and the machine body module. The support arm includes a pivot end and a push end utilized to transmit power to the jacking device. The jacking device includes a slave portion receiving the power transmitted from the push end of the support arm and a link portion pivoted to the slave portion. The link portion includes a free end motioned between a first position and a second position to drive the motion module for rotation and upward or downward movement when the slave portion is motioned in response to the power transmitted from the push end of the support arm.
