Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing structures and vehicles lack effective, lightweight, and cost-efficient penetration resistance solutions that do not interfere with their operation, aesthetics, or user mobility, particularly for transparent components like windows and doors, and do not allow bidirectional resistance for defensive purposes.
Innovation Solution
A glass treatment assembly with multiple layers and brackets that provide unidirectional projectile penetration resistance, allowing projectiles to pass through in one direction while maintaining transparency and minimizing weight and structural interference, combined with gaskets and brackets for secure mounting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If traditional storm proof windows and doors are used to provide penetration resistance, then projectile penetration resistance is improved, but weight increases substantially and structural loading exceeds existing framework capacity
Solution Approach 1:
The patent applies composite materials by combining multiple layers including glass panels, transparent polymers, and adhesive layers to create a laminated structure that provides penetration resistance. This composite approach achieves the required strength without relying on single-material heavy construction, thereby reducing overall weight while maintaining protective performance.
Solution Approach 2:
The patent utilizes parameter changes by controlling the thickness, material composition, and layer configuration of the laminated structure. By adjusting these parameters, the assembly achieves optimal penetration resistance with minimized weight, avoiding the excessive weight of traditional storm proof windows while maintaining structural integrity under projectile impact.
2Strength
If heavy penetration resistant panels are installed in existing structures, then projectile penetration resistance is improved, but the underlying structural framing cannot withstand the additional forces and loading
Solution Approach 1:
The laminated composite structure distributes impact forces across multiple layers and a broad area of the framing system. This force distribution mechanism reduces peak stresses on individual framing members, allowing existing structures to support penetration resistant assemblies without requiring reinforcement of the underlying framework.
Solution Approach 2:
By optimizing the thickness and material properties of the laminated layers, the patent reduces the overall weight of the penetration resistant assembly. This parameter optimization decreases the gravitational load and dynamic forces transmitted to the structural framing, enabling installation in existing structures without structural modification.
3Strength
If bidirectional penetration resistance is implemented in vehicle armaments, then protection against external threats is improved, but the ability to return fire or defend is eliminated
Solution Approach 1:
The patent applies local quality by providing different penetration resistance characteristics in different directions. The laminated structure is configured to offer high resistance to projectiles approaching from the external environment while maintaining transparency and structural integrity that allows controlled response from the interior, effectively creating asymmetric protective properties tailored to specific operational needs.
4Strength
If entire window and door units are replaced with storm proof assemblies, then penetration resistance is improved, but cost increases substantially and building esthetics are compromised
Solution Approach 1:
The patent applies segmentation by providing a penetration resistant assembly that can be installed as a separate layer or panel within the existing window and door framework. This segmented approach allows the protective function to be added independently without replacing the entire window or door unit, thereby reducing material costs, installation expenses, and preservation of existing aesthetic elements.
