Extendable seating interconnected mechanism and seating supporting frame
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing seating supporting frames in furniture manufacturing have complex structures, leading to high heights, large sizes, and difficulties in smooth adjustment of seating positions, which affects both space efficiency and user comfort.
Innovation Solution
The introduction of an extendable seating interconnected mechanism, comprising an interconnected assembly with a mounting plate and driving link, a seating frame, a backrest mount, and an extendable and retractable footrest mechanism, which simplifies the structure and enhances adjustability through transmitting parts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a traditional interconnected structure is used for adjusting seat position, then the seating function is achieved, but the structure becomes complex leading to high height, large volume, and space occupation
Solution Approach 1:
The interconnected structure is divided into separate functional modules: the mounting plate with lateral-plate part and supporting part, the driving link, and the backrest mount with segmented sections. Each module performs a specific function and can be independently optimized, reducing overall structural complexity and height while maintaining the seat adjustment function.
2Device complexity
If a traditional interconnected structure is used for adjusting seat position, then the seating function is achieved, but the structure becomes complex leading to large volume and space occupation during transport and use
Solution Approach 1:
The driving link is rotatably connected between the seating frame and the lateral-plate part, allowing it to nest within the structural profile when not in use. The backrest mount segments can also be positioned to minimize overall volume, enabling compact storage and transport while maintaining full functionality during use.
3Ease of operation
If a traditional interconnected structure is used, then seat position adjustment is achieved, but the adjustment becomes jamming and lagging
Solution Approach 1:
The driving link is extracted as a separate rotatable component connected between the seating frame and the lateral-plate part. This separation allows the driving link to rotate independently on its connection points, reducing friction and interference that cause jamming and lagging in integrated structures, thereby improving both smoothness and responsiveness of adjustment.

AI summary
An extendable seating interconnected mechanism and a seating supporting frame, including an interconnected assembly, a seating frame, and a backrest mount, wherein the backrest mount is rotatably connected to the interconnected assembly and the seating frame, respectively; the interconnected assembly includes a mounting plate and a driving link, wherein the mounting plate includes a lateral-plate part and a supporting part; the driving link is rotatably connected between the seating frame and the lateral-plate part; an end of the supporting part is connected to the lateral-plate part; and an opposite end of the supporting part is rotatably connected to the backrest mount. The interconnected mechanism and the seating supporting frame optimize and simplify the structure, leading to a compression of the height of the seating supporting frame; different seating positions may be adjusted smoother by connecting the extendable and retractable footrest mechanism and interconnected assembly, which improves the seating comfort.
