Split adjustable mattress foundation for multiple users

Solution Overview

Problem

Adjustable mattress assemblies designed for two users are heavy and difficult to maneuver due to duplication of components like linear actuators and electronic controls, making them costly and cumbersome during installation and assembly.

Innovation Solution

An adjustable mattress assembly with a foundation frame comprising two identical sub-foundations, where one sub-foundation includes motorized actuators and linkage assemblies to articulate the mattress sections, while the other sub-foundation is mechanically coupled to achieve similar articulation without motorized components, reducing weight and component duplication.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If two identical twin XL adjustable foundations are used to form a king or queen sized mattress assembly, then the articulation capability for two users is achieved, but the weight and difficulty of maneuvering increases significantly

Engineering Contradiction:

Improvearticulation capabilityVSAvoidweight

Core Design Contradiction:

Adaptability or versatilityVSWeight of moving object

Solution Approach 1:

The mattress assembly is divided into a head section and a foot section, each with its own foundation and articulation mechanism. The head section includes a head foundation with a head mattress support surface, and the foot section includes a foot foundation with a foot mattress support surface. This segmentation allows each section to be adjusted independently while reducing the overall weight compared to using two complete twin XL foundations.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The motorized actuators and electronic controls are extracted from the foot section, leaving only the essential structural components and linkage mechanisms. The foot foundation includes linkage assemblies with torsional springs and link arms, but omits the heavy motorized components, thereby reducing weight while maintaining articulation capability through mechanical coupling to the head section.

AI summary

Adjustable mattress assemblies and processes including an adjustable mattress foundation dimensioned to support a mattress configured to accommodate two supine users during use thereof includes a foundation frame including a first sub-foundation configured with at least one motorized actuator to effect inclination or declination of the mattress support surface and an abutting second sub-foundation free of a motorized actuator. The second foundation is mechanically coupled to the first foundation such that articulation of the first sub-foundation results in a similar articulation in the second foundation. The first and second foundations have similar length, height and width dimensions, which collectively approximates the size of the oversized mattress configured to accommodate two supine users, e.g., king size, queen size, California king size, or the like.
