Pelvic Sling with Integrated Hook and Loop Fasteners
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pelvis stabilization devices require complex placement of strap mounting pieces, necessitating proper training and familiarity, and offer limited adjustability, which can complicate their effective application in emergency situations.
Innovation Solution
A pelvis stabilizing device with a belt-like main body featuring integrated Velcro™ hook and loop fasteners allows for easy adjustment and secure tensioning without the need for separate strap mounting pieces, providing a wide range of adjustability and simplified application.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a separate strap mounting piece is used to connect the strap to the main body, then the device can be assembled, but the application process becomes complex and requires proper training
Solution Approach 1:
The patent integrates the strap mounting functionality directly into the main body of the device by incorporating Velcro™ hook and loop fasteners. This eliminates the separate strap mounting piece and simplifies the application process to a single-step operation where the strap is directly attached to the main body without requiring complex assembly or specialized training.
2Device complexity
If the strap mounting piece is fixed at a particular location, then the device structure is simplified, but the adjustability range is limited
Solution Approach 1:
The patent employs Velcro™ hook and loop fasteners that allow dynamic adjustment of the strap mounting location along the main body. This enables the device to accommodate various patient sizes and pelvic dimensions while maintaining a simple overall structure, as the fastening mechanism itself provides the necessary flexibility rather than requiring multiple fixed mounting positions.
3Ease of repair
If the strap mounting piece is removable for reuse, then the device can be reused, but the rearrangement process requires well-trained personnel
Solution Approach 1:
By integrating the strap mounting functionality directly into the main body through Velcro™ fasteners, the patent eliminates the need for removable and rearrangeable components. The strap can be easily detached and reattached to the same or different locations on the main body without requiring specialized training, making the device simple to reuse.
4Reliability
If a special buckle with tension sensing is used, then over-tightening is prevented, but the device requires multiple components and complex placement
Solution Approach 1:
The patent combines the buckle and strap mounting functions into a single integrated system with Velcro™ hook and loop fasteners. This eliminates the need for separate strap mounting pieces while maintaining reliable tension control through the friction-based Velcro™ connection, thereby reducing the total number of components and simplifying the device structure.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The device ensures rapid and effective stabilization of fractured pelvises by maintaining proper tension across a variety of patient sizes, reducing the risk of internal bleeding and facilitating transport to medical facilities with ease.
Implementation Method 1
Fastener material is provided in locations on the strap and on the main body that provide a wide range of adjustment of the effective length of the strap connection between the end of the body of the device and the buckle
Implementation Method 2
A pelvis stabilizing device with a belt-like main body featuring integrated Velcro™ hook and loop fasteners allows for easy adjustment and secure tensioning

AI summary
A hip-girdling pelvic sling device (12) for maintaining a desired amount of tension surrounding a person's hips and pelvis to securely support and stabilize a pelvis that has been fractured. Areas of mating types of fastener material such as mating hook-bearing fastener material (54) and loop pile fastener material (52) are arranged on the device to enable a strap (30) to be secured at various effective lengths to provide a wide range of adjustability to make the device (12) useful for persons of various sizes. A buckle (16) includes pins (72) that engage holes (40) in the strap (30) when the device (12) is under tension.
