Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If metal plates are used in anti-ballistic protection systems, then ballistic protection capability is improved, but weight increases excessively
Solution Approach 1:
The patent employs composite materials consisting of multiple layers including plastic layers, metal foil layers, and resin layers. This composite structure provides effective ballistic protection by combining the advantages of different materials: plastic for lightweight energy absorption, metal foil for structural integrity and bullet deformation, and resin for binding and energy dissipation. The composite approach achieves protection capability comparable to metal plates while significantly reducing overall weight.
Solution Approach 2:
The patent utilizes parameter changes in material properties during ballistic impact. The plastic layers undergo deformation and melting to absorb kinetic energy, the metal foil layers change from rigid to deformed state to stop and deform bullets, and the resin layers transition from solid to viscous state to dissipate energy. These parameter changes enable the barrier to provide effective protection without requiring excessive weight.
2Weight of moving object
If plastic materials are used in anti-ballistic protection systems, then weight is reduced, but strength and protection capability become insufficient
Solution Approach 1:
The patent combines plastic materials with metal foil and resin layers to create a composite barrier structure. The plastic layers provide lightweight energy absorption through deformation and melting, while the metal foil layers contribute to bullet stopping capability and structural strength. This composite approach maintains lightweight characteristics while achieving sufficient ballistic protection capability.
Solution Approach 2:
The patent transitions from considering single-material protection to multi-layered composite protection, adding dimensional complexity to the barrier structure. By stacking multiple layers of different materials (plastic, metal foil, resin) with specific thicknesses and arrangements, the system achieves enhanced ballistic protection while maintaining lightweight properties through optimized layer configuration.
3Stability of the object's composition
If fixed rigid barriers are used, then protection stability is improved, but energy absorption capability from ballistic impact decreases
Solution Approach 1:
The patent incorporates dynamic elements into the barrier structure, allowing the layers to move, deform, and interact during ballistic impact. The plastic layers can deform and melt dynamically to absorb energy, the metal foil layers can deform and fragment to stop bullets, and the resin layers can flow and redistribute to dissipate energy. This dynamic behavior enhances energy absorption capability while maintaining protection stability through the coordinated interaction of multiple layers.

AI summary
A method of using an anti-ballistic protection system for protecting an interior space in a building. The ballistic barrier includes a laminated material having a plurality of layers of lightweight, flexible, ballistic resistant material such as woven sheets which are secured together into the laminate using a adhesive, heat weld, or stitching. The ballistic barrier is configured to be in a compact retracted state which can be deployed to provide a protective state to protect against kinetic ballistic projectiles. The system may include an automated control system operably configured to change the state of the ballistic barrier from the retracted state to the protective deployed state, such that upon sensing a threatening event or condition triggers a transition from the retracted state to the deployed protective state such that in the protective state. The ballistic barrier in the deployed state is configured to be resistant to penetration by high-speed ballistic projectiles such as a bullet fired from a gun or a shrapnel from a bomb to protect the interior space.
