Adjustable Bed Base With Decline Feature On Both Ends
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional adjustable bed bases lack the ability to decline the head and foot platform sections, limiting their versatility for users who sleep on their stomachs or require specific health-related positions.
Innovation Solution
An adjustable bed base with a stationary frame and an articulating platform comprising a head, seat, and foot platform sections, where linear actuators can retract or extend to decline or incline these sections relative to a stationary middle platform, allowing for a U-shaped configuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional adjustable bed bases use a stationary frame with hinged deck members that can only incline, then the structure is simple and reliable, but the adaptability for different sleeping positions is insufficient
Solution Approach 1:
The bed base is divided into multiple independent platform sections (head platform section, middle platform section, foot platform section) that can be controlled separately. Each section has its own linear actuator, allowing independent adjustment of head and foot ends while keeping the middle section stationary, enabling diverse sleeping positions without requiring complete reconfiguration of the entire bed structure
Solution Approach 2:
The patent transitions from a static or singly-adjustable platform to a dynamically adjustable system where multiple platform sections can change their relative positions independently. The linear actuators enable continuous adjustment between inclined and declined positions, providing real-time adaptability for different user needs while maintaining structural integrity
2Adaptability or versatility
If the head deck member is fixedly secured or simply hinged to allow inclining, then the manufacturing is easy, but the ability to decline the platform section is lost
Solution Approach 1:
Instead of only allowing the head platform section to incline upward from the middle section, the patent enables bidirectional adjustment by positioning the linear actuator to push and pull the head platform section. This inversion of the single-direction hinged connection allows the platform to decline downward as well as incline upward, expanding position possibilities while using similar mechanical components
3Adaptability or versatility
If motorized linear actuators are added to enable declining of platform sections, then the versatility is improved, but the device complexity and cost increase
Solution Approach 1:
The linear actuators serve multiple functions: they can incline the head or foot platform sections upward, decline them downward, and maintain them at intermediate angles. This multi-functionality is achieved by positioning each actuator to push on one side of its platform section and pull on the other, allowing a single actuator to control bidirectional movement and eliminate the need for separate mechanisms for inclining and declining
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables the head and foot platform sections to be declined or inclined independently, providing customizable support for various sleeping positions and health conditions.
Implementation Method 1
Each linear actuator has a first end that is pivotally secured to a mounting bracket that is secured to a cross rail and a second end that is pivotally secured to a mounting bracket that is secured to the pusher assembly.

AI summary
An adjustable bed base has a stationary frame and a stationary seat platform raised above the stationary frame via a riser. An articulating platform includes multiple platforms hinged together. Two platforms are hinged to the stationary seat platform. Front and rear linear actuators articulate the deck such that head and foot platforms decline relative to the stationary seat platform when the linear actuators are retracted. The head and foot platforms are inclined when the linear actuators are extended.
