Solution Overview

Problem

Traditional adjustable two-person beds either lack individual control for each side, offering a unified adjustment that may not accommodate both users' preferences, or they are aesthetically unpleasing and functionally flawed due to a gap between separate mattresses.

Innovation Solution

A bed foundation designed for two people with split, movable sections that allow independent adjustment of each side, featuring a unitary mattress with articulation systems for individual control of head and upper torso positions, and a joined lower section for synchronized support of the trunk and legs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Shape

If a single mattress is used for both sides of the bed, then the aesthetic appeal and functional support are improved, but individual control of each side is lost

Engineering Contradiction:

Improveaesthetic appeal of single mattressVSAvoidindividual control of each side

Core Design Contradiction:

ShapeVSEase of operation

Solution Approach 1:

The foundation is divided into multiple independently movable sections (first foundation section, second foundation section, third foundation section) that can be adjusted separately. This segmentation allows each side of the bed to be controlled individually while the foundation remains substantially unitary, resolving the contradiction between aesthetic unity and operational independence.

Inventive Principle:

Principle #1Segmentation

2Ease of operation

If two separate adjustable mattresses are used, then individual positional control is improved, but aesthetic appeal and support along the gap deteriorate

Engineering Contradiction:

Improveindividual positional controlVSAvoidaesthetic appeal and gap support

Core Design Contradiction:

Ease of operationVSShape

Solution Approach 1:

The first foundation section and second foundation section are connected to a common third foundation section that spans across the middle of the bed. This merging creates a substantially unitary foundation structure that eliminates the gap between separate mattresses, providing continuous support while allowing independent adjustment of each side through the articulation system.

Inventive Principle:

Principle #5Merging (Combining)

3Ease of operation

If the foundation is split into separate sections for individual control, then ease of operation is improved, but structural complexity increases

Engineering Contradiction:

Improveindependent adjustment capabilityVSAvoidfoundation structure

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The articulation system is designed to control multiple foundation sections with a unified mechanism. The system can adjust the first foundation section, second foundation section, and third foundation section through coordinated movement, providing multiple adjustment capabilities while maintaining a relatively simple overall structure compared to completely separate adjustable beds.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

An articulable sleep system has a first head section, a second head section, and a joined leg section that are each separable articulable. A head motor system includes a first and second head motors operably connected to the first and second head sections. A leg motor system includes first and second leg motors operably connected to the joined leg section. A first user controlling device is hard wired to each of the first head motor, the first leg motor, and the second leg motor. A second user controlling device hard wired to each of the second head motor, the first leg motor, and the second leg motor.
