Solution Overview

Problem

Conventional warming therapy devices require complete removal of the hood component for patient access, exposing patients to ambient conditions and risking injury from falling off the platform, with limited access even in modified designs with lateral openings.

Innovation Solution

A retractable hood assembly with a pivotable top portion and adjustable sidewalls, allowing for unencumbered access without removing the entire hood, using hinged, sliding, or rotating mechanisms to position the top and sidewalls for safe and complete access.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the entire hood component is removed for patient access, then complete access to the patient is achieved, but the patient is exposed to ambient surroundings and at risk of falling off the platform

Engineering Contradiction:
Improvepatient accessVSAvoidexposure to ambient conditions and fall risk
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The hood assembly is divided into multiple independent segments: a base portion that remains stationary and a retractable top portion that can be independently moved. This segmentation allows the top portion to be accessed while the base portion maintains the protective enclosure, enabling patient access without complete hood removal and thereby preventing exposure to ambient conditions and fall risks.

Inventive Principle:
Principle #1Segmentation

2Ease of operation

If the hood component is configured with openings in lateral walls for access, then some patient access is improved, but full access for removing the patient is still limited

Engineering Contradiction:
Improvepatient accessVSAvoidfull access capability
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The hood assembly incorporates dynamic, movable components including a retractable top portion that can be pulled forward along guide members and rotated. This dynamic design transforms the static hood with fixed openings into an adaptable structure that can be reconfigured to provide various degrees of access, from partial access through lateral openings to full access by completely removing the top portion, thereby achieving both improved access and full adaptability.

Inventive Principle:
Principle #15Dynamics
