Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display screen mounting solutions, such as manual and electric hangers, face challenges in operational convenience, stability, and user experience due to complexity, high force requirements, and instability during adjustments.
Innovation Solution
A lifting display screen hanger with a movable rack assembly, a fixed rack assembly, and a balance assembly that utilizes tension springs, balance springs, pulley assemblies, and linkage components to achieve stepless height adjustment with balanced elastic forces, eliminating the need for extra limit components and reducing effort required for adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual hangers with sliding pipes and adjustable bolts are used, then height adjustment is achieved, but more force is required and extra position limit pieces are needed
Solution Approach 1:
The patent introduces a balance assembly with springs that act as a counterweight system. The balance spring supports part of the weight of the movable rack assembly, reducing the force needed by the user during height adjustment. The tension spring provides additional elastic force to assist the lifting operation, making the adjustment process easier and requiring less manual effort.
Solution Approach 2:
The patent introduces a draw cord as an intermediary element that connects the balance spring to the linkage assembly. This draw cord mediates the force transmission between the balance spring and the movable rack assembly, allowing smooth and controlled height adjustment with reduced effort.
2Extent of automation
If electric hangers with motors and drive devices are used, then lifting automation is achieved, but the overall structure becomes more complex and extra energy is needed
Solution Approach 1:
The patent implements a self-service lifting mechanism where the balance spring automatically provides the lifting force based on the weight of the display screen. The system self-regulates through the elastic forces of the springs and the mechanical advantage of the linkage assembly, eliminating the need for external power sources, motors, or control systems while maintaining automated lifting functionality.
3Ease of operation
If manual hangers with pulley sets and draw cords are used, then lifting function is achieved, but operating space is small and extra tools are required
Solution Approach 1:
The patent merges the pulley function into the linkage assembly by having the draw cord directly connect to the hinged linkage components. This integration eliminates the need for separate pulley sets and reduces the overall operating space required. The linkage assembly itself serves multiple functions including force transmission and position limiting, reducing the need for extra tools and components.
4Stability of the object's composition
If fixed non-moving displays are used, then mounting stability is achieved, but eye strain and discomfort occur due to fixed viewing position
Solution Approach 1:
The patent transforms the fixed mounting system into a dynamic one by introducing the balance assembly that enables easy height adjustment. The movable rack assembly can be smoothly repositioned to different heights using the spring-assisted mechanism, allowing the display to be adjusted to optimal viewing positions for different users while maintaining stable mounting through the balanced elastic forces.

The lower end of the tension spring is connected to the bottom of the first frame. The upper end of the balance spring is connected to the top of the second frame. The lower end of the balance spring is connected to a draw cord
Implementation Method 2
The resulting force of the tension spring and the balance spring acting on the movable rack assembly keeps balanced
Implementation Method 3
The pulley assembly comprises a first pulley component and a second pulley component. The first pulley component is located at the bottom of the second frame, comprised of a first fixed pulley and a second fixed pulley
Implementation Method 4
The linkage assembly comprises a first linkage component and a second linkage component. The first linkage component and the second linkage component intersect each other and are hinged at the intersection
