Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing adjustable bed designs are heavy, mechanically complex, and not suitable for domestic use due to weight, cost, and mechanical simplicity issues, posing challenges in storage, transportation, and logistics within the furniture industry.
Innovation Solution
An adjustable bed with a frame divided into two hinged sections, featuring a head end and toe end sub-assembly that can be folded for reduced length during transportation and storage, and a simplified actuation system using a linear actuator and H-frame mechanism, allowing for easy assembly and deployment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a robust mechanical structure with multiple rollers and curved tubes is used to achieve reliable angular adjustment, then the reliability of the adjustable section is improved, but the weight and device complexity increase significantly
Solution Approach 1:
The bed frame is divided into two separate hinged sections (head end sub-assembly and toe end sub-assembly) that can be folded together for transportation and then unfolded to form the complete bed structure. This segmentation simplifies the overall mechanical structure while maintaining adjustment reliability through the hinge mechanism.
Solution Approach 2:
The hinge connection enables dynamic adjustment of the bed sections, allowing the frame to transition between folded and unfolded states. The actuator means provides controlled angular adjustment of the adjustable body support section, creating a dynamic system that adapts to different positions without requiring complex mechanical structures.
2Ease of operation
If a complete adjustable bed structure is manufactured and shipped, then the ease of operation is improved, but the cost of transportation and storage increases due to large dimensions
Solution Approach 1:
The bed frame is segmented into two hinged sections that can be folded together to reduce the length dimension for transportation and storage. This allows the complete bed structure to be shipped in a compact form while maintaining the capability for easy assembly by simply unfolding the sections at the destination.
Solution Approach 2:
The hinged connection provides dynamic configurability, allowing the bed to transition between a compact folded state for shipping and a full extended state for use. This dynamic capability reduces shipping volume while preserving ease of assembly through a simple unfold operation.
3Stability of the object's composition
If traditional non-folding bed designs are used, then the structural integrity is maintained, but the adaptability for different transportation and storage conditions deteriorates
Solution Approach 1:
The bed frame is divided into two hinged sections that maintain structural integrity through the hinge connection while enabling folding for transportation and storage. This segmentation provides adaptability to different logistics conditions without compromising the stability and integrity of the overall structure when assembled.
Solution Approach 2:
The hinge mechanism provides dynamic adaptability, allowing the bed structure to adjust between folded and unfolded configurations. This dynamic capability enables the bed to adapt to various transportation and storage conditions while maintaining structural integrity through the robust hinge connection and locking mechanism.

AI summary
The invention provides an adjustable bed comprising a frame (20) and at least one adjustable body support section including at least an adjustable backrest support section (12) pivotally mounted for angular adjustment with respect to the frame. The frame comprises at least two hinged sections (20a, 20b) including a head end sub-assembly configured as an upper body supporting section on which the backrest support section is mounted, and a separate toe end sub-assembly configured as a lower body supporting section hinged with respect to the upper body supporting section. Actuator means (40) is disposed within at least the upper body section for angular adjustment of the adjustable body support section. The head end sub-assembly and the toe end sub-assembly are capable of being folded together to reduce the length dimension of the bed for transportation and/or storage purposes and subsequently unfolded to provide a full length adjustable bed.
