Solution Overview
Problem
Conventional mounting mechanisms for large-size displays do not allow for easy height adjustment, requiring users to dismantle and reassemble the system, which is inconvenient and costly due to the need for electric power and increased configuration and construction costs.
Innovation Solution
A lifting device comprising a stationary member, a lifting member, and multiple springs that allow manual adjustment of the display's height, with elastic forces holding the display in place after manual force is removed, enabling effortless height adjustment without the need for electric power.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If an electric lifting motor and control circuit are integrated into the stand for effortless height adjustment, then the display can be adjusted easily without dismantling, but the device requires electric power, occupies additional configuration space, and increases manufacture and construction costs
Solution Approach 1:
The patent extracts the lifting function from the stand and implements it through a separate lifting device comprising a lifting member, stationary member, and spring mechanism. This separation eliminates the need for electric motors and control circuits in the stand, reducing configuration space and power requirements while maintaining effortless height adjustment capability
Solution Approach 2:
The spring mechanism in the lifting device provides automatic counterbalancing force to offset the weight of the display, enabling the system to serve itself without external power. The spring's elastic force naturally compensates for gravitational force, allowing easy height adjustment without motors or electrical systems
2Stability of the object's composition
If the display is fixed to a wall or stand through mounting mechanisms, then the display is securely mounted, but the height cannot be adjusted after fixation and reassembly is required for height changes
Solution Approach 1:
The patent transforms the static mounting system into a dynamic one by introducing a lifting member that can slide vertically along the stationary member. This allows the display height to be adjusted continuously after wall mounting, combining mounting stability with height adjustment flexibility through the movable lifting mechanism
Solution Approach 2:
The mounting system is segmented into distinct components: a stationary member fixed to the wall, a movable lifting member, and a display mounting structure. This segmentation allows the display to remain securely mounted while enabling independent height adjustment through the lifting member's vertical movement
3Area of moving object
If the display weight is more than tens of kilograms, then the display provides large screen area, but manual handling becomes inconvenient and requires assistance
Solution Approach 1:
The patent applies the counterweight principle by using a spring mechanism that generates upward elastic force to counterbalance the downward gravitational force on the heavy display. This counterbalancing effect reduces the effort needed for manual handling, allowing users to easily adjust the position of large, heavy displays without requiring multiple people or mechanical assistance

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables quick and effortless height adjustment of large-size displays, reducing installation complexity and costs by using manual force and elastic forces to maintain the display's position, while preventing unexpected falls.
Implementation Method 1
the first springs are stretched by the lifting member and exert a first elastic force on the lifting member, wherein the first elastic force is approximate to the weight of the lifting member and the weight of the display
