Transparent Projectile-Proof Panels with Segmented Glass and Plastic Layers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current projectile-proof glass systems are heavy, expensive, and become opaque after impact, limiting their use in applications like goggles and helmets where weight reduction and continued visibility are crucial.
Innovation Solution
The development of non-bonded, visually transparent projectile-proof panels comprising glass and plastic subpanels with an open space between them, allowing the glass to shatter and be ejected while the plastic absorbs energy, maintaining transparency and reducing weight.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the thickness of laminates (glass or plastic) is increased to achieve higher bullet/projectile resistance, then penetration resistance is improved, but weight increases and light transmission decreases
Solution Approach 1:
The patent divides the protective structure into separate glass layers and plastic layers arranged in alternating sequences, with each layer serving a specific function. The glass layers provide ballistic resistance while the plastic layers provide flexibility and weight reduction, creating a segmented composite structure that optimizes both protection and weight.
Solution Approach 2:
The patent uses composite materials consisting of multiple glass sheets and plastic sheets laminated together in a specific sequence. This composite structure combines the high strength-to-weight ratio of glass with the flexibility and weight advantages of plastic, achieving both ballistic resistance and reduced weight compared to traditional single-material constructions.
2Strength
If the number of layers of glass, plastic and adhesive is increased to provide higher protection from bullet and projects, then protection level is improved, but weight increases and visibility decreases
Solution Approach 1:
The patent applies different materials to different regions of the protective panel - glass sheets are positioned where maximum protection is needed, while plastic sheets are positioned where weight reduction and flexibility are prioritized. This local differentiation allows optimization of both protection level and visibility without requiring uniform thickening throughout.
3Stability of the object's composition
If glass sheets are laminated together with high levels of heat treatment to cause significantly high adhesion, then structural integrity is improved, but the weight and complexity increase
Solution Approach 1:
The patent introduces plastic sheets as intermediary layers between glass sheets, which serve as both structural binders and weight-reducing elements. These plastic intermediaries provide the necessary adhesion and structural integrity while being lighter than alternative bonding methods, avoiding the need for heavy heat treatment processes.
