Adjustable Bed with Slidable Assemblies to Prevent Abdominal Pressure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Adjustable beds with fixed lengths can cause discomfort when the upper portion is lifted, as the abdomen is pressed due to the lack of length adjustment, which is not addressed by existing designs.
Innovation Solution
The adjustable bed features a slidable assembly system with a head lift motor that allows the upper seat platform and lower seat platform to separate or close, extending or reducing the bed's length, using C steel brackets and a guiding slot mechanism to accommodate the head lift motor and support platform, enabling comfortable positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the upper portion of the adjustable bed is lifted, then the head elevation is improved, but the bed length remains fixed causing abdominal pressure
Solution Approach 1:
The bed incorporates slidable assemblies that allow the seat platforms to move dynamically along the side rails. When the head portion is elevated, the upper seat platform slides upward relative to the lower seat platform, dynamically extending the bed length to accommodate the elevated position without pressing against the abdomen.
Solution Approach 2:
The bed is divided into separate slidable assembly components including upper and lower seat platforms that can independently move relative to each other. This segmentation allows the bed to be divided into movable segments that can adjust their positions to extend the overall bed length when needed.
2Object-affected harmful factors
If the bed length is extended to prevent abdominal pressure, then user comfort is improved, but the structural complexity increases
Solution Approach 1:
The slidable assembly components are nested within the bed frame structure. The upper and lower seat platforms are positioned one above the other, with the upper platform sliding within the confines of the lower platform's vertical space, effectively nesting the extension mechanism within the existing bed structure.
Solution Approach 2:
The slidable assemblies serve multiple functions: they provide the extension mechanism to prevent abdominal pressure, they enable adjustable bed positions, and they integrate with the existing head lift motor and frame structure. This multi-functionality reduces the need for separate dedicated components.

AI summary
An adjustable bed includes a head frame assembly, a first slidable assembly having a slidable assembly base and slidable assembly sides slidable within lower C steel brackets; head lift arm bracket assemblies pivotally connected to the slidable assembly sides; and a head lift platform mounted on the head lift arm bracket assemblies, an upper seat platform mounted on the first slidable assembly, and a lower seat platform movably attached onto the higher C steel bracket; a second slidable assembly with a spacing bracket having a guiding slot mounted on the slidable assembly base and the fixing bracket being mounted on the lower seat platform, and the connecting bolt mounted on the fixing bracket and received in the guiding slot; and a head lift motor secured to the head frame assembly for operably driving the head lift arm bracket assemblies in head lift forward or backward direction.
