Wearable Airbag Dislocation Prevention via Segmented Inflatable Portions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wearable airbag devices often fail to adequately protect targeted body parts due to airbag dislocation during deployment, which compromises their effectiveness in providing necessary protection.
Innovation Solution
A wearable airbag device featuring a flexible airbag with inflatable portions and a connecting means, such as through holes and connecting belts or interlocking parts, to prevent dislocation from the targeted body part during deployment, ensuring accurate coverage and protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the airbag is made flexible to conform to body contours, then comfort and adaptability are improved, but the airbag may dislocate from the targeted body part during deployment
Solution Approach 1:
The airbag is divided into multiple inflatable portions (first, second, third, and fourth portions) that can be independently positioned around the hip. This segmentation allows each portion to conform to specific body contours while collectively maintaining stable positioning through distributed connection points with the wearable device.
Solution Approach 2:
The connection means is pre-configured between the airbag and wearable device before deployment. This preliminary connection ensures that when the airbag inflates, it remains anchored to the targeted body part, preventing dislocation while allowing the flexible material to conform to body shape.
2Ease of operation
If the airbag is designed to be compact for wearability, then ease of operation and portability are improved, but the protective coverage area may be insufficient
Solution Approach 1:
The airbag portions are arranged in a nested configuration around the hip, with inner and outer portions overlapping and interlocking. This nesting allows the airbag to maintain a compact profile when deflated for wearability while expanding to provide comprehensive protective coverage when inflated.
Solution Approach 2:
The airbag utilizes three-dimensional spatial arrangement with portions positioned at different heights and angles around the hip. This multi-dimensional configuration maximizes protective coverage volume while maintaining a compact form factor that does not interfere with normal wearability.
3Reliability
If connection means is added to prevent dislocation, then positioning accuracy is improved, but device complexity increases
Solution Approach 1:
The connection means utilizes flexible straps or bands that integrate with the wearable device structure. These thin, flexible connection elements provide effective anchoring without adding significant structural complexity, maintaining simplicity while ensuring the airbag remains positioned on the targeted body part.

AI summary
A wearable airbag device that is adapted to be worn by a wearer for protecting one or more targeted body parts of the wearer. The airbag device includes an airbag that includes one or more protecting inflatable portions each of which is configured to be inflated with an inflation gas and cover one of the one or more targeted body parts, and a means for preventing each of the protecting inflatable portions from being dislocated from the targeted body part at airbag deployment.
