Convertible sofa bed system
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional convertible sofa beds have limitations in design, including permanent connections of discrete elements to the frame, which can increase manufacturing costs and make maintenance and replacement of components difficult.
Innovation Solution
A convertible sofa bed system featuring a back support assembly with a frame and tether elements that allow the back cushion assembly to move between raised and lowered positions, enabling a seating or sleeping configuration, and includes modular body components with adjustable table elements and storage compartments, facilitating easy conversion and maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If discrete elements are permanently secured to the frame, then structural stability is improved, but manufacturing cost increases and maintenance becomes difficult
Solution Approach 1:
The sofa bed is divided into modular components including removable back cushions, separate body modules, and interchangeable cover elements. This segmentation allows individual parts to be manufactured separately at lower costs and enables easy replacement or maintenance of specific components without affecting the entire structure.
2Stability of the object's composition
If discrete elements are permanently secured to the frame, then structural stability is improved, but ease of maintenance and replacement is worsened
Solution Approach 1:
The design incorporates dynamic connection mechanisms where back cushions can be attached and detached from the frame, and body modules can be reconfigured. This dynamic approach maintains structural stability during use while enabling easy maintenance and replacement when needed.
3Adaptability or versatility
If back cushion assembly is movable between raised and lowered conditions, then versatility is improved, but device complexity increases
Solution Approach 1:
The back cushion assembly is segmented into multiple cushions that can independently be positioned or removed. This segmentation provides configuration versatility for different seating and sleeping arrangements while avoiding the need for complex mechanical mechanisms, as the cushions can be manually repositioned without sophisticated hardware.

AI summary
A convertible sofa bed system positionable on a floor. The convertible sofa bed system includes a back support assembly having a frame, and a back cushion assembly connected with the back support assembly and movable between a raised condition and a lowered condition thereof. The system also includes one or more body modules secured to the frame. The body module includes an at least partially planar top surface positionable at a predetermined elevation above the floor. The body module is formed to cooperate with the back cushion assembly in the raised condition to define a seating configuration, and to cooperate with the back cushion assembly in the lowered condition to define a sleeping configuration.
