Adjustable Gas Spring Pressure Equalization for Table Load Matching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing height-adjustable furniture, such as tables, require individual manufacturing of table columns to accommodate varying weight loads, leading to increased manufacturing and assembly efforts due to the need for specific spring forces in gas pressure springs, which are not easily adjustable.
Innovation Solution
An adjustable gas pressure spring system comprising a gas spring portion, a gas reservoir, and a connecting means that allows for fluid communication between the two, enabling adjustment of spring force through pressure equalization, allowing for individual adjustment of spring force without the need for multiple components, and includes an adjusting means such as a piston or external gas cylinder for easy adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If individual manufacturing of table columns is performed to accommodate varying weight loads, then the spring force can be precisely matched to specific load requirements, but the manufacturing effort, assembly effort, and storage requirements increase significantly
Solution Approach 1:
The patent applies parameter changes by enabling adjustment of the gas pressure spring's internal pressure after manufacturing. Instead of creating different springs for different loads, a single spring design can be adjusted to match various weight requirements by modifying the pressure parameter, thereby resolving the contradiction between precise spring force matching and manufacturing complexity
Solution Approach 2:
The invention introduces dynamic adjustability to the gas pressure spring system, allowing the spring force to be changed based on actual load requirements. This dynamic capability eliminates the need for individual manufacturing of multiple spring types, as the same spring can be dynamically adjusted to suit different furniture weight configurations
2Manufacturing precision
If individual manufacturing of table columns is performed to accommodate varying weight loads, then the spring force can be precisely matched to specific load requirements, but the assembly effort and storage requirements increase significantly
Solution Approach 1:
The patent implements universality by designing a standardized gas pressure spring that can serve multiple functions across different furniture applications. The spring's adjustability allows it to be universally applied to various load requirements without requiring custom-manufactured components, thereby reducing assembly effort and simplifying storage logistics
3Ease of manufacture
If fixed spring force gas pressure springs are used, then the manufacturing process is simplified, but the furniture cannot accommodate fluctuating weight loads or be adjusted to different height positions
Solution Approach 1:
The invention resolves this contradiction by maintaining simple manufacturing of a standard gas pressure spring while adding the capability to change its pressure parameter after manufacturing. This allows the spring to adapt to different weight loads and height requirements without complicating the initial manufacturing process, achieving both manufacturing simplicity and load adaptability

Function Achieved in This Case
This solution simplifies the manufacturing and assembly of height-adjustable furniture by allowing for customizable spring force adjustments, accommodating fluctuating weight loads and reducing the risk of overloading or damage during height adjustments, while also enabling quick and easy operation by users.
Implementation Method 1
The spring force of the gas spring portion is adjustable by pressure equalization with the gas reservoir or also to the ambient pressure
Implementation Method 2
the adjustment means of the gas reservoir is a piston which is configured to be pushed into the gas reservoir or pulled out from the gas reservoir

AI summary
An adjustable gas pressure spring includes a gas pressure spring portion, a gas reservoir and a connecting means fluidically connecting the gas reservoir and the gas pressure spring portion with each other. The spring force of the gas pressure spring portion is adjustable by means of pressure equalization with the gas reservoir and/or the ambient pressure. Such a gas spring is provided in an adjustable column, in particular an adjustable table column. The table column is in turn provided in a height-adjustable table.
