Last year a great step in the evolution of defense systems has occurred, in a perfect accordance with the TRIZ Principles. To better appreciate this step, and to see TRIZ in action, let's step back and draw a brief evolutionary line starting at about 2000 BC with one of the first defense systems.

It was an implementation of Principle 11, "Beforehand cushioning": The Shield.

Jumping forward, at about 1000 AD, we find an implementation of Principle 7, "Nested doll": The Armor.

Much later, in 1916, Principle 3, "Local quality": The Gas Mask.

Next big war, 1940, Principle 28, "Mechanics substitution": The Radar.

Our times, 1991, Principle 17, "Another dimension": The Patriot Missile.

And finally, in 2003, Principle 30, "Flexible shells and thin films": The Duct Tape.
