Solution Overview

Problem

Conventional adjustable bed solutions in hospitals and care institutions lack a universal adjustment mechanism that allows users with reduced mobility to independently move in and out of bed, requiring caregiver assistance and limiting self-reliance and privacy.

Innovation Solution

An adjustable bed with a sleeping platform frame structure supported by an adjustable pedestal, integrating a seat module with motor and drive wheel bogie, enabling height adjustment, longitudinal tilt, and lateral tilt, allowing users to move independently through the foot end of the bed without caregiver assistance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If conventional adjustable bed solutions are used, then basic bed adjustments are available, but users with reduced mobility cannot independently move in and out of bed

Engineering Contradiction:

ImproveIndependent movement capabilityVSAvoidBed structure complexity

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The patent combines a conventional adjustable bed with a wheelchair into a single integrated unit. The wheelchair is positioned within the bed frame structure, and the sleeping platform can be adjusted to transform the configuration between bed and wheelchair modes, enabling independent movement without requiring separate devices

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The integrated bed-wheelchair solution provides multiple functions in one device: it serves as a sleeping bed with adjustable positions, a wheelchair for independent movement, and a transfer system between the two modes. This eliminates the need for separate bed and wheelchair devices

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If a wheelchair is integrated into the bed structure, then independent movement is enabled, but the sleeping platform adjustments are limited

Engineering Contradiction:

ImprovePosition adjustment capabilityVSAvoidMovement independence

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The bed structure incorporates dynamic adjustment mechanisms that allow the sleeping platform to change its configuration. The platform can be adjusted to different angles and positions to facilitate transformation between bed and wheelchair modes, and to enable various sleeping and treatment positions while maintaining movement independence

Inventive Principle:

Principle #15Dynamics

3Ease of operation

If the sleeping platform is divided into longitudinal sections, then wheelchair integration is possible, but other adjustment possibilities are limited

Engineering Contradiction:

ImproveCaregiver assistance requirementVSAvoidTreatment position adjustment

Core Design Contradiction:

Ease of operationVSAdaptability or versatility

Solution Approach 1:

The sleeping platform is divided into longitudinal sections to accommodate the wheelchair structure within the bed frame. This segmentation allows the wheelchair to be positioned within the middle section while the side sections remain available for sleeping and treatment adjustments, enabling both independent movement and various treatment positions

Inventive Principle:

Principle #1Segmentation
