Solution Overview
Problem
Adjustable bed bases with articulating platforms often create sharp angles, leading to mattress misalignment and discomfort, as well as unsightly gaps between the mattress and the base, which can disrupt sleep quality.
Innovation Solution
An adjustable base assembly with a fixed frame and an articulating frame, featuring an upper body frame, seat frame, and leg frame that move relative to each other, utilizing linking arms and rollers to maintain mattress contour and prevent pinching, along with actuators and linkages to adjust positions ergonomically.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If rigid segments and hinges are used to create an articulating platform, then the base can be adjusted to ergonomic positions, but sharp angles are created at hinge locations causing mattress misalignment and gaps
Solution Approach 1:
The articulating frame is divided into multiple segments (upper body frame, seat frame, leg frame) that can move independently relative to each other. This segmentation allows each segment to adjust to maintain mattress contour while providing overall ergonomic positioning capability
Solution Approach 2:
The patent transforms the static rigid segments into dynamic components where the upper body frame and seat frame can move linearly along the fixed frame. This dynamic adjustment capability allows the system to adapt the shape continuously, eliminating sharp angles and maintaining mattress contour throughout the range of motion
2Adaptability or versatility
If the upper and lower sections of the articulating base move during articulation, then ergonomic positioning is achieved, but users are moved away from nightstands and unsightly gaps are created
Solution Approach 1:
The upper body frame is designed to move linearly along the fixed frame while maintaining its horizontal position relative to the nightstand. This dynamic horizontal movement capability allows the upper body to articulate ergonomically without being displaced away from the nightstand, and prevents gap formation at the head of the bed
3Ease of operation
If traditional articulating mechanisms are used, then base adjustment is achieved, but the mattress assumes a pinched or folded configuration causing discomfort
Solution Approach 1:
The patent implements a dynamic system where the upper body frame moves linearly along the fixed frame during articulation. This linear movement mechanism ensures that the mattress remains smooth and evenly distributed across the support surface, preventing pinching and folding that would occur with traditional hinge-based articulating mechanisms
Solution Approach 2:
The fixed frame with its linear guides acts as an intermediary mechanism between the actuator and the upper body frame. This intermediary structure controls the movement path to ensure smooth, linear translation that maintains mattress contour and prevents harmful pinching effects

AI summary
An adjustable base is provided that includes a fixed frame and an articulating frame connected to the fixed frame. The articulating frame includes an upper body frame pivotally connected to the upper section of the fixed frame, a seat frame pivotally connected to the upper body frame and movable along a central section of the fixed frame, and a leg frame pivotally connected to the fixed frame. An actuator is further included and has a first end connected to the seat frame adjacent to the leg frame and a second end that is connected to a linkage attached to the articulating frame. Upon activation of the actuator, the upper body frame is articulated upward and the seat frame moves linearly along the central section of the fixed frame toward the upper section of the fixed frame. Systems and methods for controlling an adjustable base assembly are further provided.
