Segmented Anti Ballistic Helmet Shell Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current helmets used by security forces are less effective in providing trauma resistance to the operative front, rear, and peripheral areas, particularly against sniper fire and other projectiles, with higher back face deformation values that increase the risk of fatal injuries.
Innovation Solution
A trauma-resistant anti-ballistic helmet design featuring a shell composed of helmet pre-forms with strategically placed first and second back face deformation shields, covered by an anti-ballistic sheet, providing enhanced protection to the front, rear, and periphery areas through fusion, welding, or adhesion of various materials like light alloys and woven fabrics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If traditional ballistic fabrics and pressure molded shells are used, then the helmet provides basic ballistic protection, but the trauma resistance to the operative front portion, operative rear portion and periphery is comparatively less effective
Solution Approach 1:
The helmet shell is divided into multiple pre-form segments (front pre-form, rear pre-form, and periphery pre-forms) that are assembled together. This segmentation allows each portion to be optimized independently for trauma resistance while maintaining overall structural integrity, directly addressing the weakness in traditional uniform-shell designs.
Solution Approach 2:
Different portions of the helmet (front, rear, and periphery) are constructed with varying thicknesses, material densities, and reinforcement levels according to their specific ballistic exposure requirements. The operative front and rear portions receive enhanced protection compared to traditional designs, while maintaining cost-effectiveness through localized rather than universal reinforcement.
2Object-affected harmful factors
If traditional helmet designs are used, then manufacturing is relatively simple, but the helmet is comparatively less effective in providing trauma resistance from snipers, enemy fire and other harmful projectiles
Solution Approach 1:
The shell is manufactured as separate pre-form segments using standard molding techniques, which can then be assembled through bonding or mechanical fastening. This approach maintains manufacturing simplicity while enabling enhanced trauma resistance through the segmented structure that better distributes impact forces from sniper fire and projectiles.
Solution Approach 2:
The helmet incorporates composite construction with multiple material layers and densities within the pre-forms, combining different ballistic fabrics and resin formulations to optimize trauma resistance against various threats while maintaining compatibility with existing manufacturing processes.
3Object-affected harmful factors
If uniform thickness shell is used, then manufacturing is easier, but the operative front portion, operative rear portion and periphery have comparatively less trauma resistance
Solution Approach 1:
Rather than attempting to manufacture a single uniform shell with varying thickness, the design segments the shell into multiple pre-forms that are each molded with uniform thickness. The varying protection levels are achieved through the assembly configuration and bonding of these segments, maintaining manufacturing precision while achieving the desired trauma resistance gradient.
Solution Approach 2:
Each pre-form segment is manufactured with uniform thickness and quality standards, but the segments themselves have different geometries and reinforcement characteristics tailored to their specific locations (front, rear, periphery). This approach maintains manufacturing precision while achieving local optimization for trauma resistance.
