Adjustable beds
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional adjustable beds face the issue of the bottom-end section of the mattress-carrying framework being detached from the rest, limiting the involvement of the foot-part of the mattress in articulations and turning, which compromises user comfort due to insufficient height and obstruction by the floor.
Innovation Solution
The bottom-end section of the framework is attached to a penultimate section for coordinated turning and elevation, and is selectively detachable to allow downward inclination for user access, ensuring the foot-part of the mattress remains engaged throughout the articulations and turning process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the bottom-end section is permanently detached from the framework, then the framework can be inclined downwardly to facilitate user entry and exit, but the foot-part of the mattress becomes uninvolved in articulations, compromising user comfort
Solution Approach 1:
The bottom-end section is made dynamically attachable and detachable to the framework through a selective attachment mechanism. This allows the system to switch between two states: attached for comfort during articulations, and detached for downward inclination during entry/exit operations, resolving the contradiction between maintaining mattress involvement and enabling floor clearance.
2Adaptability or versatility
If the framework height is increased to maintain foot-part involvement, then user comfort is improved, but the downward inclination is obstructed by floor impact
Solution Approach 1:
The framework height is made dynamically adjustable through selective detachment of the bottom-end section. When downward inclination is needed for entry/exit, the bottom-end section is detached to lower the framework height and clear the floor. When articulation is needed, the bottom-end section is attached to maintain proper height and foot-part involvement, resolving the height contradiction.
3Adaptability or versatility
If the bottom-end section is permanently attached to the framework, then the foot-part remains involved in articulations, but the framework cannot be selectively inclined downwardly without obstruction
Solution Approach 1:
The permanent attachment is replaced with a selective attachment mechanism that allows the bottom-end section to be either attached or detached based on operational needs. This dynamic configuration enables the framework to maintain foot-part involvement during articulations while allowing selective downward inclination during entry/exit, resolving the contradiction between permanence and flexibility.
4Ease of operation
If the framework is configured for sideways deployment, then accessibility is improved, but the bottom-end section obstruction by the floor limits the deployment angle
Solution Approach 1:
The framework configuration for sideways deployment is enhanced with selective attachment of the bottom-end section. This allows the deployment angle to be dynamically adjusted: when maximum accessibility is needed, the bottom-end section is detached to increase the deployment angle beyond what would be possible with permanent attachment, while maintaining the sideways deployment configuration for improved accessibility.

AI summary
An adjustable bed has five individually articulated sections of the length of a framework, 2, that carry its mattress, 1, and which are selectively controllable by the user via actuating equipment, 5, to vary the relative angles between them, and to deploy the framework, 2, turned sideways in length, with selectively, a downward inclination. A bottom-end section, 24, of the framework, 2, is attached to a penultimate section, 23, of the framework to move with it in turning and elevation of the framework, and is selectively detachable from it to allow the framework to be selectively inclined downwardly to facilitate entry and exit of a user to, and from, the bed, when the framework is deployed turned sideways in length.
