Adjustable bed systems with rotating articulating bed frame
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional adjustable beds do not accommodate individuals with limited mobility, as they lack features to assist with getting in and out of bed due to a fixed sleeping surface height and lack of rotation or tilting mechanisms, making it difficult for those with mobility issues to align their body properly and safely enter or exit the bed.
Innovation Solution
An adjustable bed system with a rotating and pivoting mechanism that allows the sleeping surface to rotate around a vertical axis, tilt, and move laterally, enabling the bed to be adjusted to various positions, including lowering the foot portion below the horizontal plane, to facilitate easier access and alignment for individuals with limited mobility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the bed frame uses a fixed height design to accommodate support members and actuators, then the structural stability is improved, but the ease of operation for individuals with limited mobility deteriorates
Solution Approach 1:
The bed frame incorporates a rotating mechanism that allows the sleeping surface to dynamically change its orientation and position. The foundation can rotate around a vertical axis and tilt at various angles, transforming the static fixed-height structure into a dynamic system that adapts to user needs, particularly facilitating easier access for individuals with limited mobility.
Solution Approach 2:
The invention adds rotational and tilting dimensions to the traditional bed frame structure. Instead of only vertical height adjustment, the foundation can now rotate horizontally and tilt at multiple angles, creating three-dimensional movement capabilities that enable the sleeping surface to reach positions accessible to users with mobility limitations.
2Device complexity
If the sleeping surface is positioned at a fixed height to accommodate support members, then the device complexity is reduced, but the adaptability for different user needs deteriorates
Solution Approach 1:
The bed foundation is designed with dynamic rotational and tilting capabilities, allowing it to change its configuration from a fixed position to multiple adjustable positions. This dynamic behavior enables the same structure to adapt to different user requirements without requiring multiple separate devices or complex assemblies.
Solution Approach 2:
The rotating and tilting mechanism provides multi-functionality, allowing the bed to serve both traditional sleeping purposes and assistive functions for individuals with mobility limitations. The same foundation structure can be positioned in various orientations to accommodate different user needs, making the device universally applicable to a broader range of users.
3Manufacturing precision
If the bed foundation is fixed in position, then the manufacturing precision requirements are reduced, but the ease of operation for individuals with limited mobility deteriorates
Solution Approach 1:
The foundation incorporates dynamic rotational and tilting mechanisms that allow the sleeping surface to move to various positions. This dynamic capability enables the bed to be positioned in orientations that facilitate easier access for users with limited mobility, such as rotating the foot portion toward the user or tilting the sleeping surface to create a ramp-like entry.
4Stability of the object's composition
If the bed frame maintains a fixed horizontal support surface, then the structural stability is improved, but the adaptability for assisting individuals with limited mobility deteriorates
Solution Approach 1:
The bed foundation is designed with dynamic rotational and tilting capabilities, allowing it to change its configuration from a fixed position to multiple adjustable positions. This dynamic behavior enables the same structure to adapt to user needs, particularly facilitating easier access for individuals with limited mobility.
Solution Approach 2:
The invention adds rotational and tilting dimensions to the traditional bed frame structure. Instead of only vertical height adjustment, the foundation can now rotate horizontally and tilt at multiple angles, creating three-dimensional movement capabilities that enable the sleeping surface to reach positions accessible to users with mobility limitations.

AI summary
A rotating and articulating bed has a fixed bed frame, a rotation assembly mounted on the fixed bed frame, a pivot assembly mounted on the rotation assembly and an articulating bed frame mounted on the pivot assembly. The articulating bed frame contains a plurality of pivotally connected distinct portions. The rotation assembly rotates the pivot assembly and the articulating bed frame with respect to the fixed bed frame on a plurality of discrete wheel bearings around a vertical axis passing through the rotating and articulating bed. The articulating bed frame articulates the distinct portions and the pivot assembly tilts the articulating bed frame with respect to a horizontal plane that is perpendicular to the vertical axis independent of rotation by the rotation assembly and articulation by the articulating bed frame.
