Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing gas spring supporting mechanisms for displays are limited by their volume, resulting in a restricted reaction force and load capacity, which is not conducive to miniaturization and improved support applications.
Innovation Solution
A supporting device that incorporates a gas spring with a compression spring, where the piston rod is slidably disposed through a hollow tube, allowing for variable movement and increased pressure without increasing the volume, by utilizing a compression spring to enhance the elastic force and load capacity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If the volume of the gas spring is increased to provide greater reaction force, then the load capacity is improved, but the size of the supporting mechanism increases, which is not conducive to miniaturization
Solution Approach 1:
The patent applies the nesting principle by placing the compression spring inside the hollow tube of the gas spring. The compression spring is positioned within the internal space of the hollow tube, allowing it to nested within the existing gas spring structure without increasing the overall volume. This nested configuration enables the compression spring to contribute additional elastic force to the piston rod, thereby increasing the reaction force and load capacity while maintaining the compact size of the supporting mechanism.
2Force
If the volume of the gas spring is increased to provide greater reaction force, then the load capacity is improved, but the device complexity increases due to additional components
Solution Approach 1:
The compression spring is nested within the hollow tube of the gas spring, utilizing the existing internal space. This nesting approach adds functionality (increased elastic force) without requiring a completely new structural design. The compression spring shares the same axial space as the gas spring, and both springs work together through the piston rod, integrating their functions rather than adding separate complex mechanisms.
Solution Approach 2:
The patent merges the functions of the gas spring and compression spring into a unified supporting system. Both springs are connected to the piston rod and work together to provide the reaction force. The gas spring provides primary supporting force through gas pressure, while the compression spring provides additional elastic force, and their combined effect increases the overall load capacity without requiring separate mounting structures or complex control systems.
