Helmet Emergency Removal Pad Segmentation Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Full-face helmets have a complex structure that increases manufacturing costs and are not easily removable, even by a third person in emergency situations, due to the complex shape of interrupt portions and the need for precise guidance between male and female hooks.
Innovation Solution
A helmet design featuring emergency removal pads with a pad bag, pad body, and pad removal part, including a connecting member, slider, and interlocking elements, allowing the pad body to be easily taken out from the pad bag attached to the helmet's opening edge, simplifying the removal process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a full-face helmet with thick cushion pad around the neck is used to provide sufficient head protection, then head protection is improved, but the helmet becomes difficult to remove even by the user themselves
Solution Approach 1:
The cushion pad is divided into multiple independent sections: a front cushion pad, a rear cushion pad, and side cushion pads. Each section is separately attachable and removable from the shock absorbing body, allowing the rear cushion pad to be quickly removed by a third person in emergencies while the front cushion pad remains for head protection
Solution Approach 2:
The rear cushion pad is designed to be extractable from the helmet structure. A third person can access and remove the rear cushion pad through the rear opening without needing to remove the entire helmet or deal with the front cushion pad, enabling quick emergency removal
2Ease of operation
If a recess-projection engagement mechanism with complex interrupt portions is used to enable pad removal, then pad removability is improved, but the structure becomes complex and manufacturing costs increase
Solution Approach 1:
The engagement mechanism is segmented into simple male hooks on the cushion pad and corresponding female hooks on the shock absorbing body. This segmentation allows each component to have a simple, standardized shape that is easy to manufacture and assemble, avoiding the need for complex interrupt portions
Solution Approach 2:
The engagement mechanism uses localized hook structures at specific attachment points rather than a complex overall structure. The male and female hooks provide sufficient engagement strength while maintaining simple geometries that are easy to guide and assemble
3Ease of manufacture
If a simple pad attachment structure is used to reduce manufacturing costs, then manufacturing cost is improved, but the pad cannot be reliably removed in emergency situations
Solution Approach 1:
The cushion pad system is segmented into front and rear sections with different attachment characteristics. The rear cushion pad uses a simple hook-based attachment that allows reliable removal by a third person, while the front cushion pad provides stable attachment for head protection
Solution Approach 2:
The rear cushion pad is designed for easy extraction through the rear opening while maintaining secure attachment during normal use. The simple hook structure allows the pad to be reliably removed in emergencies without requiring complex release mechanisms

AI summary
A helmet that is reliably and quickly removable from the head of a user by a third person includes a head covering shell having an insertion opening that opens downward and configured to protect the head of the user; a shock absorbing body disposed adjacent to an inner periphery of the head covering shell to reduce shock to the head of the user; and a cushion pad disposed adjacent to an inner periphery of the shock absorbing body to fill a gap between the shock absorbing body and the head. The cushion pad includes an emergency removal pad at a position along an opening edge of the insertion opening. The emergency removal pad includes a pad bag having a hollow interior, a pad body disposed in the pad bag, and a pad removal part that enables the pad body to be taken out from the pad bag attached to the opening edge of the insertion opening.
