Solution Overview

Problem

Existing inflatable patient warming devices are not suitable for patients who need to move about and require access to specific anatomical areas, leading to inconvenience and impaired mobility, and there is a need for diverse gown configurations that can be manufactured efficiently.

Innovation Solution

A clinical garment with a front panel comprising an insulated sheet and a permeable sheet, featuring an inflatable blanket section and a removable forced air warming blanket pocket, allowing for patient warming through convection and mobility, with manufacturing techniques that include automated and manual assembly processes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Temperature

If an inflatable warming blanket is used to provide patient warming, then patient warming effectiveness is improved, but patient mobility and access to anatomical areas deteriorates

Engineering Contradiction:
Improvepatient warming effectivenessVSAvoidpatient mobility and anatomical access
Core Design Contradiction:
TemperatureVSEase of operation

Solution Approach 1:

The warming device is divided into separate modular components including a vest portion, blanket portion, and removable warming elements. This segmentation allows the warming function to be distributed across multiple independent components that can be adjusted and reconfigured based on patient needs, enabling both effective warming and maintained mobility.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The device incorporates adjustable and removable warming components that can be dynamically configured. The vest portion can be worn independently, the blanket portion can be added or removed, and air bladders can be selectively inflated or deflated. This dynamic configuration allows the warming effectiveness to be adjusted without restricting patient movement or access to anatomical areas.

Inventive Principle:
Principle #15Dynamics

2Temperature

If an inflatable warming blanket is used to cover the patient, then patient warming is achieved, but device complexity and manufacturing difficulty increases

Engineering Contradiction:
Improvepatient warmingVSAvoiddevice manufacturing and assembly
Core Design Contradiction:
TemperatureVSEase of manufacture

Solution Approach 1:

The device is manufactured as separate modular components (vest portion, blanket portion, air bladders, warming elements) that can be produced independently using standardized processes. This segmentation simplifies manufacturing by allowing each component to be optimized and produced separately, then assembled through straightforward connections, reducing overall manufacturing complexity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The vest portion and blanket portion are designed as universal components that can function independently or in combination. The same basic components can serve multiple purposes (warming, mobility, different anatomical configurations) which simplifies the manufacturing process by reducing the need for specialized parts for each function.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Adaptability or versatility

If a removable forced air warming blanket pocket is included in the garment, then versatility and adaptability are improved, but device complexity increases

Engineering Contradiction:
Improvegown configuration versatilityVSAvoidgarment structure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The removable forced air warming blanket is nested within a pocket integrated into the vest portion. This nesting arrangement allows the warming element to be stored compactly within the garment structure when not in use, and easily removed or inserted when needed. The pocket structure provides a simple mechanical interface that reduces complexity compared to integrated permanent warming systems.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The removable pocket design allows the warming element to be dynamically added or removed based on clinical needs. This dynamic configuration provides versatility for different patient requirements and anatomical access needs without requiring a complex permanent structure, as the warming capability can be activated or deactivated simply by inserting or removing the blanket element.

Inventive Principle:
Principle #15Dynamics
