Ultra-thin four-fold electric bed
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing folding beds, such as the double-motor folding bed, only achieve two-layer folding and occupy a large volume after folding, necessitating significant storage space.
Innovation Solution
An ultra-thin four-fold electric bed design featuring a rear and front supporting frame that are both foldable, with hinge connections between bed plates and driven by linear actuators, allowing for a four-section folding mechanism that minimizes thickness by aligning all supporting structures and driving members within the same plane during folding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a two-layer folding mechanism is used, then the bed can be folded and stored, but the folded volume remains large and occupies significant storage space
Solution Approach 1:
The bed structure is divided into four independently foldable sections: headboard assembly, backrest assembly, leg assembly, and footboard assembly. Each section can be folded separately through hinge connections, enabling a four-fold mechanism that reduces the folded volume to approximately one-quarter of the original size compared to traditional two-layer folding designs.
Solution Approach 2:
The patent employs a planar folding design where all supporting frames and driving members are arranged to fold within the same plane. This two-dimensional folding approach allows the bed to collapse flat against itself, minimizing the thickness and overall volume of the folded state while maintaining structural integrity through coordinated hinge movements.
2Stability of the object's composition
If multiple supporting frames and driving members are included, then the bed provides stable support and adjustable positioning, but the folded thickness increases
Solution Approach 1:
The patent integrates the driving members (linear actuators) directly onto the supporting frames, with motors mounted on frame members and linkage mechanisms connected to the same structural elements. This merging of support and actuation functions eliminates the need for separate mounting structures, allowing all components to fold within the same plane and minimizing folded thickness while maintaining support stability.
Solution Approach 2:
The design allows inner components to be nested within or against outer structures during folding. The supporting frames are arranged to fold against each other in a nested configuration, with driving members positioned to nest within the folded envelope of the frame structure, thereby reducing overall folded dimensions without compromising structural integrity.

AI summary
An ultra-thin four-fold electric bed is provided, and belongs to the technical field of folding beds. The ultra-thin four-fold electric bed includes a rear supporting frame, a front supporting frame, a front hip bed plate, a rear hip bed plate, a leg bed plate, a footboard, a backrest bed plate, a headboard, a first driving member, and a second driving member. When a bottom of the rear hip bed plate and a bottom of the front hip bed plate are folded to each other, the rear supporting frame and the front supporting frame are located within the same plane. By using a four-section folding design and combining a staggered coplanar design of the rear supporting frame and the front supporting frame, all the supporting structures and the driving members are completely stored between the bed plates after folding, to implement thickness minimization.
