Solution Overview
Problem
Conventional adjustable bed bases lack the ability to decline the head and foot platform sections, limiting their functionality for users who prefer a curved sleeping surface or have specific health needs.
Innovation Solution
An adjustable bed base with a stationary middle platform and articulated head and foot platform sections, which can be inclined or declined using motorized linear actuators, allowing for customizable positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional adjustable bed bases use a stationary frame with hinged deck members, then the bed can be inclined for sitting or leg elevation, but the head and foot platform sections cannot be declined below horizontal position
Solution Approach 1:
The platform is divided into three separate hinged sections: head platform section, middle platform section, and foot platform section. Each section can be independently adjusted by its own linear actuator, enabling selective inclination or decline of different platform portions without requiring complex integrated mechanisms.
Solution Approach 2:
The patent employs motorized linear actuators that can dynamically adjust the platform sections between inclined and declined positions. The actuators provide controlled motion in both directions (above and below horizontal), transforming the static platform into a dynamically adjustable surface that adapts to various user needs.
2Adaptability or versatility
If the head and foot platform sections are made articulated with independent linear actuators, then decline capability is achieved, but the device complexity increases
Solution Approach 1:
The linear actuators serve multiple functions: they can incline platform sections above horizontal, decline them below horizontal, and maintain them in any intermediate position. This multi-functionality reduces the need for separate mechanisms for different adjustment directions, optimizing the component count while achieving comprehensive position control.
Solution Approach 2:
The middle platform section acts as an intermediary element between the head and foot sections. It provides a stable reference point and structural connection, allowing the head and foot sections to be adjusted independently while maintaining overall platform integrity and reducing the complexity of direct head-to-foot section coupling.
3Shape
If the middle platform section is raised relative to the frame, then a curved sleeping surface is created, but the structural complexity increases
Solution Approach 1:
The middle platform section is elevated using a linear actuator that can dynamically adjust its height relative to the frame. This creates a curved sleeping surface configuration when needed, while allowing the middle section to return to a lower position when a flat surface is desired, providing shape variability without permanent structural complexity.
Solution Approach 2:
The platform is segmented into three independently adjustable sections, with the middle section capable of vertical displacement. This segmentation allows the middle section to be raised to create curvature while keeping the head and foot sections at their original levels, achieving the desired shape without requiring complex overall frame restructuring.

AI summary
An adjustable bed base has a stationary frame and a stationary seat platform raised above the stationary frame. An articulating platform includes at least three platforms, head and foot platforms being hinged to the stationary seat platform. Front and rear linear actuators articulate the deck such that the head and foot platforms decline relative to the stationary seat platform when the linear actuators are fully retracted. The head and foot platforms are inclined when the linear actuators are fully extended.
