Innovative Sofa Bed Design for Easy Switching and Stability
Here’s PatSnap Eureka !
Summary
Problems
Conventional sofa beds are difficult to switch between states, lack stability, and do not offer sufficient comfort or versatility, making them inconvenient for users.
Innovation solutions
A sofa bed design featuring a hinge mechanism with three sections at the connection between the backrest and seat portions, a supporting pipe for stability, and detachable elastic modules that can be easily mounted and dismounted for comfort, allowing for smooth transitions between sofa and bed configurations.
TRIZ Analysis
Specific contradictions:
General conflict description:
Principle concept:
If a conventional sofa bed structure is used, then the structure is simple, but the switching between sofa and bed configurations is difficult and not smooth
Why choose this principle:
The hinge mechanism is divided into three sections that can rotate relative to each other, allowing the backrest and seat to transition smoothly between configurations. This segmentation enables independent movement of each section, making the switching operation easier and more controlled.
Principle concept:
If a conventional sofa bed structure is used, then the structure is simple, but the switching between sofa and bed configurations is difficult and not smooth
Why choose this principle:
The hinge mechanism incorporates dynamic rotation capabilities with multiple degrees of freedom, allowing the sofa bed to transition dynamically between sofa and bed states. The pin sliding in the sliding groove provides continuous motion control rather than fixed rigid connections.

Abstract
A sofa bed has a seat portion, a backrest portion and a hinge mechanism including a first section, a second section and a third section sequentially and pivotably connected. The first section is fixed to a side of the seat portion. The second section is fixed to a side of the backrest portion. A protruding portion is provided at a position where the first section is connected with the second section. Each of the armrest frames is formed with a slideway for receiving and guiding the protruding portion. An end of the third section opposite to the second section is pivotally connected to the armrest. The first section and the second section are be lockable to place the main body frame into a sofa configuration. The sofa bed can be easily switched between sofa and bed positions.
