Solution Overview

Problem

Care beds for bedridden individuals face challenges in facilitating independent toileting, showering, and preventing bedsores, with existing solutions being inconvenient, requiring significant nursing assistance, and compromising comfort and hygiene.

Innovation Solution

A multi-function care bed with foldable panels that convert into a chair, a movable bed frame, and integrated systems for body movement, showering, and toileting, including a portable toilet and water collector, which allows for automatic operation and reduced caregiver intervention, enhancing comfort and reducing the risk of bedsores.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a mattress with openings is used for toileting, then toileting function is provided, but patient comfort deteriorates due to contamination and discomfort

Engineering Contradiction:

Improvetoileting functionVSAvoidcontamination and discomfort

Core Design Contradiction:

Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The bed system is divided into separate functional modules: a sleeping bed portion and a chair portion with integrated toilet. This segmentation allows the toilet function to be isolated from the sleeping area, preventing contamination of bedding while maintaining patient comfort in both zones.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

A transfer mechanism acts as an intermediary between the bed and toilet, enabling the patient to be moved between these functions without direct contact or contamination. The transfer system includes support surfaces and positioning mechanisms that maintain hygiene and comfort during transitions.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Adaptability or versatility

If a waterproof surface mattress is used for showering, then showering function is provided, but sleeping comfort deteriorates

Engineering Contradiction:

Improveshowering functionVSAvoidsleeping comfort

Core Design Contradiction:

Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The system separates showering and sleeping functions into different zones. The showering area uses waterproof surfaces for hygiene, while the sleeping bed maintains soft, comfortable bedding. A transfer mechanism connects these zones, allowing patients to move between functions without compromising comfort in either area.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The transfer mechanism serves as an intermediary that enables transition between the waterproof showering surface and the comfortable sleeping surface. This mediator allows the patient to access showering functionality while returning to a comfortable sleeping environment, resolving the conflict between hygiene and comfort.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Stability of the object's composition

If the bed frame is fixed, then structural stability is maintained, but transfer of patient between bed and flatbed requires significant nursing assistance

Engineering Contradiction:

Improvestructural stabilityVSAvoidpatient transfer

Core Design Contradiction:

Stability of the object's compositionVSEase of operation

Solution Approach 1:

The bed frame incorporates movable and adjustable components that allow dynamic reconfiguration during patient transfer. The frame can be positioned at different heights and angles, and the flatbed can be adjusted to match the bed frame's position, facilitating easier patient transfer while maintaining structural stability when in fixed positions.

Inventive Principle:

Principle #15Dynamics

4Ease of operation

If manual showering assistance is provided, then personal care is achieved, but patient embarrassment increases due to caregiver contact

Engineering Contradiction:

Improvepersonal careVSAvoidpatient embarrassment

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The shower system is designed to enable patients to shower independently without direct caregiver contact. Features include a movable shower head that can be positioned automatically, a waterproof chair that contains water, and controls that allow patients to manage their own hygiene needs, thereby reducing embarrassment while maintaining care quality.

Inventive Principle:

Principle #25Self-service

AI summary

A multi-function care bed is disclosed including a flatbed having a plurality of panels foldable between a first configuration in which the plurality of panels are adapted to support a person in a horizontal position, and a second configuration in which the plurality of panels are adapted to form a chair to support the person in a seated position. The multi-function care bed also includes a bed frame configured to support the person on a mattress, the bed frame being movable between a first position in which the bed frame substantially overlies the flatbed, and a second position in which the plurality of panels of the flatbed are exposed so as to allow transfer of the person between the bed frame and the flatbed. The multi-function care bed also includes a body movement system in which a group of arms lift, lower, roll, or massage the person.
