Support for seating furniture and item of seating furniture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing seating furniture mechanisms lack an additional degree of freedom of movement, which is often achieved at the cost of increased design complexity and expense, particularly in providing lateral tilting movements that are not optimally ergonomic.
Innovation Solution
A support system for seating furniture that includes a main body with a connecting unit allowing inclination relative to a supporting element, featuring a convex contact base for point contact with a contact head, enabling 360-degree movement without requiring additional installation space or complex design, and incorporating elastic restoring elements for self-correction and optional blocking mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If lateral tilting movements are added to seating furniture mechanisms, then movement freedom is improved, but design complexity and production cost increase
Solution Approach 1:
The support is divided into a main body and a separately fitted connecting unit. This segmentation allows the connecting unit to provide lateral tilting movement capability independently, while the main body maintains its primary supporting function, thus adding movement freedom without significantly increasing overall design complexity
Solution Approach 2:
The connecting unit is designed to be fitted on the main body to enable inclination alteration, transforming a static support structure into a dynamic one that can adapt its orientation. This dynamic capability provides lateral tilting movement while keeping the base structure simple and cost-effective
2Ease of manufacture
If a separately fitted connecting unit is used instead of a one-piece construction, then ease of manufacture is improved, but structural stability may worsen
Solution Approach 1:
By separating the support into a main body and a connecting unit that can be fitted independently, the invention simplifies manufacturing processes and assembly operations while maintaining structural integrity through proper design of the connection interface
Solution Approach 2:
The contact base and contact head form an intermediary connection interface between the main body and supporting element. This intermediary design allows for easy assembly and disassembly while providing sufficient structural stability through the geometric relationship of the contacting surfaces

Function Achieved in This Case
This solution provides an additional degree of freedom for seating furniture components in all directions, enhancing ergonomics while maintaining a low design and production cost, and can be integrated into various types of seating mechanisms without increasing structural complexity.
Implementation Method 1
the contact base abuts with the contact head at a given point rather than over an entire surface area, thereby forming a non-planar contact
Implementation Method 2
incorporating elastic restoring elements for self-correction

AI summary
A support for a piece of seating furniture provides an additional degree of freedom of movement. The support has a connecting unit fitted on a main body that connects to a supporting element of an underframe. The connecting unit has a mounting device for the supporting element, in particular a mount for the upper end of the supporting element. The connecting unit is fitted on the main body such that it is possible to alter the inclination of the main body relative to the supporting element. For that purpose the main body has a preferably convex contact base, which in the fitted state is contacted by a contact head of the connecting unit, with the abutment forming a non-planar contact rather than a contact over a surface area, in particular a punctiform contact.
