Overlapping Strap Lifting Device for Secure Grip and Weight Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current lifting devices for bariatric or geriatric individuals are difficult to grip, often single-use, and challenging to position, especially in confined spaces, and lack versatility for lifting or moving objects other than people.
Innovation Solution
A pair of overlapping straps with multiple loop members of varying diameters, integrated for secure gripping and distribution of weight, made from durable materials like seat belt webbing, allowing multiple users to lift or drag objects safely and efficiently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If towels or sheets are used as makeshift lifting devices, then multiple people can lift the person at the same time, but the devices are difficult to grip
Solution Approach 1:
The strap is divided into multiple segments including a first strap portion, a second strap portion, and a connector portion with stitching elements. This segmentation creates distinct functional zones: the first and second strap portions provide gripping surfaces for lifters, while the connector portion securely attaches to the patient, resolving the contradiction between ease of gripping and lifting security
Solution Approach 2:
Different portions of the strap have different properties optimized for their specific functions. The first and second strap portions are designed for gripping with appropriate texture and dimensions, while the connector portion is designed for secure attachment with stitching elements. This local differentiation ensures both easy gripping and reliable lifting security
2Ease of operation
If single-use lifting devices like Megamover are used, then multiple lifters can lift the person at the same time, but the devices are difficult to position under the person, especially in confined spaces
Solution Approach 1:
The lifting device is segmented into flexible strap portions that can be easily maneuvered and positioned in confined spaces, unlike rigid single-use devices. The strap can be threaded and adjusted through tight areas, then secured around the patient, making positioning easier while maintaining the capability for multiple lifters
Solution Approach 2:
The strap device is dynamic and adaptable, allowing it to be configured in different ways depending on the situation. It can be positioned, adjusted, and repositioned as needed, unlike fixed single-use devices. This dynamic nature enables easy positioning in confined spaces while supporting multiple lifters
3Adaptability or versatility
If single-purpose lifting devices are used, then they can lift fallen people, but they cannot be easily used to lift or drag objects other than fallen people
Solution Approach 1:
The strap device is designed with universal application capability. The same strap configuration can be used to lift patients, drag patients, or lift other objects. The first and second strap portions can engage different anchor points or objects, making the device versatile for multiple lifting and dragging applications without increasing complexity
