Solution Overview

Problem

Existing patient transfer methods require multiple sizes and orientations of slide sheets for different movements, leading to stock management issues and increased training needs for healthcare workers, which can result in misuse and injuries.

Innovation Solution

A patient transfer apparatus with an elongate open-ended tube formed from flexible sheet material and extending flap portions allows for multiple directional movements, reducing the need for multiple sheets and simplifying alignment, enabling a single apparatus to perform lateral, longitudinal, and rotational transfers.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple sizes and orientations of slide sheets are used for different patient movements, then the ability to perform various transfers (lateral, longitudinal, rotational) is improved, but the device complexity and stock management requirements increase

Engineering Contradiction:
Improveability to perform various transfersVSAvoidnumber of slide sheet sizes and orientations
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The slide sheet is designed with a tubular configuration that can be rotated to different orientations, allowing a single sheet to perform lateral transfers, longitudinal transfers, and rotational transfers. The tube structure enables the sheet to be positioned in multiple orientations around the patient, eliminating the need for separate sheets for different transfer types.

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

Solution Approach 2:

The slide sheet incorporates a rotatable tubular structure that can be dynamically repositioned between different orientations. The tube can rotate 360 degrees around the patient, allowing the same sheet to adapt to different transfer requirements by changing its orientation rather than requiring multiple static sheets of different sizes.

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If multiple sizes of slide sheets are stocked for different patient sizes and movements, then the suitability for various patients is improved, but the loss of time for stock handling and tracking increases

Engineering Contradiction:
Improvesuitability for various patientsVSAvoidtime for stock handling and tracking
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

A single tubular slide sheet design can accommodate different patient sizes and transfer types through rotation and repositioning, eliminating the need to stock multiple sizes. This universal design reduces inventory complexity and the time required to locate and manage appropriate slide sheets for different patients.

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

3Reliability

If healthcare workers are trained to use multiple orientations of slide sheets for different movements, then the safety and proper usage are improved, but the ease of operation decreases due to increased training requirements

Engineering Contradiction:
Improvesafety and proper usageVSAvoidtraining requirements
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The rotatable tubular design provides a consistent, universal method for all transfer types. Healthcare workers learn one standardized technique for positioning and rotating the tube rather than memorizing multiple orientations for different sheet sizes, reducing training complexity while maintaining safety through proper rotational positioning.

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