Nice idea, but if you want it to actually work, you need to think beyond “just more metal.” The key is the energy absorption curve—try a layered composite where the outermost shell converts impact to heat, the middle layer uses a viscoelastic core to damp vibrations, and the inner layer is a magnetic field to redirect any residual kinetic energy. Also, keep the weight down; a 30% lighter shield is easier to field, and that saves you the whole logistics nightmare. And remember, design isn’t about piling on more layers; it’s about the perfect balance between mass, response time, and durability.
