Adjustable bed with dual-tilt adjustable foundation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing adjustable bed technologies do not effectively allow for independent tilting of the mattress support surface relative to the subframe, limiting user positioning options and comfort.
Innovation Solution
A dual-tilt adjustable foundation with a subframe that includes upper and lower segments capable of rotation, featuring a mattress support surface with pivotally attached deck sections and connectors that adjust angles when actuated, enabling the upper subframe to tilt between inclined, flat, and declined positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the mattress support surface is fixed relative to the subframe, then the structural simplicity is maintained, but the user positioning flexibility is limited
Solution Approach 1:
The subframe is divided into upper and lower segments that can rotate relative to each other, while the mattress support surface is segmented into multiple deck sections that can tilt independently. This segmentation allows each part to perform specific functions (upper subframe provides stable base, lower subframe enables tilting, deck sections enable independent positioning) without requiring the entire structure to be complex, thus achieving positioning flexibility while controlling overall structural complexity
Solution Approach 2:
The patent transforms the fixed static structure into a dynamic adjustable structure by introducing rotation joints between upper and lower subframe segments, and tilt mechanisms between deck sections. These dynamic elements allow the mattress support surface to adjust to multiple positions (elevated, declined, flat) while maintaining structural integrity, resolving the contradiction between adaptability and complexity
2Adaptability or versatility
If the upper subframe segment is made rotatable to enable tilting, then the positioning options are increased, but the mechanical complexity increases
Solution Approach 1:
The subframe is segmented into upper and lower portions that can rotate relative to each other at defined pivot points. This segmentation allows the tilting function to be isolated to specific mechanical joints rather than requiring complex mechanisms throughout the entire structure, enabling positioning options while controlling mechanical complexity
Solution Approach 2:
The rotation mechanism between upper and lower subframe segments serves multiple functions: it enables the upper portion to tilt for positioning adjustments, provides structural support, and works in conjunction with the deck section tilt mechanisms to achieve compound positioning. This multi-functionality reduces the need for separate dedicated mechanisms, thereby increasing positioning options without proportionally increasing mechanical complexity

AI summary
The disclosure generally relates to an adjustable foundation or bed, in particular having a dual-tilt adjustable foundation. Upper and lower segments of the adjustable foundation subframe are rotatable relative to each other, thus allowing the upper portion of the subframe to tilt and assume an inclined, flat/horizontal, or declined position relative to the lower portion of the subframe. An articulating mattress support surface above the subframe can move independently from the tilting subframe.
