Metal-Mesh Tunic with Dynamic Neck Aperture for Easy Donning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Metal-mesh safety fabrics, used for protection against sharp instruments and punctures, are difficult to don and doff due to their design, which can be problematic for individuals wearing headgear or requiring quick removal in emergency situations.
Innovation Solution
A metal-mesh tunic with a closed-figure neck aperture that converts to an open-figure for easy donning and doffing, and a metal-mesh glove with a magnetic wrist-securing band for secure and quick removal, allowing the garment to be put on and taken off without overhead maneuvers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If metal-mesh protective clothing is designed with a closed-figure neck aperture for full protection, then protection coverage is improved, but ease of donning and doffing deteriorates
Solution Approach 1:
The neck aperture is designed to dynamically change its configuration between a closed-figure state during wear (providing full protection) and an open-figure state during donning/doffing (providing ease of operation). The aperture can be opened laterally or vertically to allow insertion of head and arms, then closed to provide full protective coverage when worn.
2Reliability
If metal-mesh protective clothing requires overhead maneuvers for donning, then full protection is achieved, but speed of donning and doffing deteriorates
Solution Approach 1:
The aperture configuration dynamically transitions between closed and open states, allowing the garment to be donned and doffed without overhead maneuvers by opening the aperture laterally or vertically, thereby reducing the time required for donning and doffing while maintaining full protection when closed.
Solution Approach 2:
The aperture is pre-configured to open in specific directions (laterally or vertically) that facilitate quick insertion of head and arms without requiring overhead maneuvers, enabling rapid donning while ensuring full protection once closed.
3Reliability
If metal-mesh protective clothing is designed for secure fit, then protection effectiveness is improved, but ease of removal in emergencies deteriorates
Solution Approach 1:
The neck aperture dynamically opens to an open-figure configuration that allows rapid removal of the garment in emergency situations without requiring overhead maneuvers, while maintaining a secure closed-figure fit during normal wear to ensure protection effectiveness.
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
Enables easy and quick donning and doffing of protective metal-mesh clothing, even when wearing headgear, facilitating rapid removal in emergency situations and providing full frontal armored protection without the need for overhead maneuvers.
Implementation Method 1
having a magnet attached to a free end, wherein the metal-mesh securing band secures the glove to a user by circumscribing the wrist of the user, the magnet attaching to an underlying circumscribed portion of the securing band

AI summary
A metal-mesh tunic (125) has an apron region and two full-length sleeves (120), the tunic (125) presenting a closed-figure neck aperture through which a user's head (155) and neck (150) project when worn, the neck aperture becoming an open-figure to facilitate easy donning and doffing without requiring a pullover action. In an illustrative embodiment, the tunic (125) may present a contiguous protective surface from the neck region of a user (110) down to a knee region. A closure system (140) secures the tunic (125) to a user (110) by fixing the closed-figure neck aperture around the user's neck (150). The closure system (140) may have a buckle including a male member attached to one side of the neck region and a female member on an other side of the neck region. In an exemplary embodiment, the metal-mesh tunic (125) may advantageously provide full frontal armored protection in an easily donned garment.
