Adjustable bed base with incline/decline feature
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional adjustable bed bases lack the ability to incline or decline the articulated deck when the deck members are flat and aligned, which is a limitation for individuals with health issues such as circulation problems or gastroesophageal reflux disease, as they require specific inclinations of the bed platform.
Innovation Solution
An adjustable bed base design featuring a movable subframe that can be inclined or declined using motorized primary and secondary linear actuators and ramps, allowing the subframe to pivot relative to a stationary frame, enabling the deck to be tilted regardless of its position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a stationary frame with articulated deck members is used, then the bed base provides structural stability and support, but the deck cannot be inclined or declined when members are flat and aligned
Solution Approach 1:
The frame is divided into a stationary lower frame and a movable upper frame (subframe), allowing independent movement of the upper frame to achieve incline/decline functionality while maintaining structural stability through the stationary lower frame
Solution Approach 2:
The upper frame is made movable relative to the stationary lower frame through ramps and linear actuators, transforming the previously static frame structure into a dynamic system that can adjust inclination angles while maintaining overall structural integrity
2Adaptability or versatility
If motorized linear actuators are added to incline deck members, then user comfort is improved, but the bed base cannot provide flat platform inclination for health conditions
Solution Approach 1:
Ramps are introduced as intermediary elements between the stationary lower frame and the movable upper frame. The ramps translate linear actuator movement into angular inclination of the entire upper frame, enabling flat platform tilt without requiring complex actuation of individual deck members
Solution Approach 2:
The motorized linear actuators serve multiple functions: they can incline individual deck members for user comfort and simultaneously incline the entire upper frame to provide flat platform inclination for health conditions, making the system versatile for different user needs
3Ease of operation
If the articulated deck is designed for sitting positions, then reading and watching television is enabled, but health conditions requiring flat platform inclination cannot be accommodated
Solution Approach 1:
The upper frame is made dynamically adjustable relative to the stationary lower frame, allowing the system to switch between articulated sitting positions for comfort and flat platform inclinations for health conditions, providing adaptability while maintaining ease of operation through motorized control

AI summary
An adjustable bed base has a subframe assembly including a subframe which may be inclined relative to a stationary frame by a primary linear actuator. An articulating deck is attached to the subframe. Secondary linear actuators articulate the deck. The subframe assembly is pivotally secured to a portion of the stationary frame. The subframe may be inclined by extending the primary linear actuator which moves ramps, causing wheels attached to the subframe to ride upwardly along the ramps, thereby raising the head end of the subframe relative to the stationary frame.
