Solution Overview

Problem

Existing patient isolation devices do not effectively adapt to different transfer surfaces and do not provide comfortable isolation for patients, while also being cumbersome to fold and transport.

Innovation Solution

A foldable patient isolation device with a base comprising contiguous inflatable modules that can be folded between modules, allowing the base to adapt to various surfaces, and a support structure with expandable profiles to maintain the chamber's shape, along with a support profile for the patient's head and easy folding mechanisms.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the base is made as a single rigid structure, then the device maintains structural stability, but it cannot adapt to different transfer surfaces and is difficult to fold

Engineering Contradiction:
Improveadaptability to different transfer surfacesVSAvoidfolding mechanism complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The base is divided into multiple contiguous modules that can be folded relative to each other. Each module can independently adapt to the surface contour while maintaining overall structural integrity, enabling the base to conform to different transfer surfaces and fold compactly for transport.

Inventive Principle:
Principle #1Segmentation

2Stability of the object's composition

If the chamber wall is kept expanded using closely spaced profiles, then the chamber maintains its shape, but the device becomes bulky and difficult to fold

Engineering Contradiction:
Improvechamber shape stabilityVSAvoidfolding difficulty
Core Design Contradiction:
Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The support structure uses spaced profiles that create segmented support zones along the chamber. This segmentation allows the chamber to maintain its expanded shape during use while enabling the profiles to be folded closer together during transport, reducing bulk without compromising structural integrity.

Inventive Principle:
Principle #1Segmentation

3Reliability

If personal protective equipment is used to protect health professionals, then safety against infectious agents is improved, but additional disinfection procedures are required after patient transfer

Engineering Contradiction:
Improveprotection against infectious agentsVSAvoiddisinfection time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The isolation chamber extracts and contains the infectious risk within a sealed environment, separating the contaminated patient from the clean healthcare environment. This eliminates the need for extensive disinfection of surrounding areas after patient transfer, as the contamination remains confined to the removable chamber.

Inventive Principle:
Principle #2Taking out (Extraction)

4Reliability

If the device is designed for complete patient isolation, then infection risk is reduced, but patient comfort during transfer is compromised

Engineering Contradiction:
Improveisolation effectivenessVSAvoidpatient comfort
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The base modules are designed to be dynamically adjustable, allowing the isolation device to adapt its configuration based on the patient's position and comfort needs. The modules can be inflated or adjusted to provide support and comfort while maintaining the sealed isolation environment, enabling both effective isolation and patient comfort during transfer.

Inventive Principle:
Principle #15Dynamics
