Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing patient transfer devices require significant physical labor, cause discomfort by lifting or turning patients, are bulky, or necessitate complex mechanisms, and often require low friction surfaces that are unsuitable for injured patients.
Innovation Solution
A foldable board and mattress system with embedded roller assemblies and foldable parts that allow seamless patient transfer without electricity, enabling nesting and secure positioning, and can be easily stored and maintained.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional patient transfer devices are used, then patient transfer can be achieved, but significant physical labor is required and patient comfort is compromised due to lifting or turning
Solution Approach 1:
The bed is divided into multiple foldable parts (head section, foot section, intermediate sections) that can be independently manipulated. This segmentation allows the bed to be folded into a compact configuration that can be rolled onto the stretcher without requiring lifting or turning of the patient, thereby reducing physical labor and maintaining patient comfort.
Solution Approach 2:
The bed incorporates foldable joints and movable sections that enable dynamic reconfiguration of the bed structure. These dynamic features allow the bed to transform from a standard sleeping configuration to a compact rolled configuration, facilitating easy transfer to stretchers while keeping the patient in a stable, comfortable position throughout the process.
2Adaptability or versatility
If bulky transfer devices with complex mechanisms are used, then patient transfer capability is improved, but device portability and ease of storage deteriorate
Solution Approach 1:
The bed frame is segmented into multiple hinged sections that can be folded together into a compact rolled configuration. This segmentation enables the bed to transition from a large, versatile patient transfer device to a compact, portable form that requires minimal storage space, eliminating the need for bulky mechanisms while maintaining transfer capability.
Solution Approach 2:
The bed is designed to be folded and rolled into a compact cylindrical form that can be easily stored in vehicles or compact spaces. The nested folding structure allows the entire bed framework to be condensed into a small volume, achieving portability without sacrificing the bed's functionality when deployed.
3Ease of operation
If low friction surfaces are used for patient transfer, then transfer smoothness is improved, but patient safety deteriorates due to lack of secure positioning
Solution Approach 1:
The mattress is divided into multiple foldable sections that can be independently manipulated during transfer. This segmentation allows the mattress to be folded along with the bed frame, creating a secure encapsulated structure that holds the patient safely during transfer while maintaining smooth movement through the foldable joints.
Solution Approach 2:
The foldable mattress sections dynamically adjust during the transfer process, maintaining patient security through controlled movement. The flexible yet structured design of the foldable mattress sections provides both smooth transfer and reliable patient positioning, eliminating the need for low friction surfaces that would compromise safety.
