Split adjustable mattress foundation for multiple users
Find Innovative SolutionsGenerate Solutions
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
A split adjustable mattress foundation comprising two sub-foundations with similar dimensions, 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 additional actuators, reducing weight and component duplication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If two identical twin XL adjustable foundations are used to form a queen or king sized mattress assembly, then the assembly can accommodate two users, but the weight and difficulty of maneuvering increases significantly
Solution Approach 1:
The patent merges the actuation systems of two separate foundations by coupling torsional shafts between them, allowing a single motorized actuator in one sub-foundation to control articulation of both sub-foundations. This consolidation reduces the total number of actuators and electronic controls while maintaining the capacity to accommodate two users, thereby reducing overall weight and improving maneuverability during installation and assembly
2Adaptability or versatility
If two identical twin XL adjustable foundations are used to form a queen or king sized mattress assembly, then the assembly can accommodate two users, but the complexity and cost of components increases due to duplication
Solution Approach 1:
The patent merges the actuation systems of two separate foundations by coupling torsional shafts between them, allowing a single motorized actuator in one sub-foundation to control articulation of both sub-foundations. This consolidation reduces the total number of actuators and electronic controls while maintaining the capacity to accommodate two users, thereby reducing overall weight and improving maneuverability during installation and assembly
Solution Approach 2:
The motorized actuator in the first sub-foundation serves a dual function by controlling both its own articulation and the articulation of the second sub-foundation through the coupled torsional shafts. This multi-functionality eliminates the need for separate actuators in each sub-foundation, reducing component complexity and cost
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
The solution allows for a lighter, more maneuverable adjustable mattress assembly that maintains the functionality of accommodating two users without duplicating components, enhancing ease of installation and reducing costs.
Implementation Method 1
first and second spaced apart torsional members coupled to the linkage support frame underlying each end of the intermediate seat section
Implementation Method 2
head and back section hingedly connected to an intermediate seat section at one end and a leg and foot section hingedly connected to the intermediate seat section at another end
Implementation Method 3
one or more motorized actuators in the first sub-foundation having one end coupled to the cross rail and another end coupled to one of the crank arms effective to selectively rotate the first and/or second torsional members

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.
