With the disadvantages of complex structure, complicated operation and power control, the application of existing high-building escape device are restricted. A novel high-building escape device is designed based on TRIZ theory, which has the advantages of simple structure, easy operation and without electric or other energy. With the transformation of closed-loop mechanism, the gravity of escape person generate the resistance preventing the rapid drop of escape person. The closed-loop mechanism consists of driving shaft, feedback shaft, drving gear, feedback gear and rope. One end of the rope is winded around the driving shaft, and another end is tied with escape person. With the reduction of layers number of rope, the pressure angle between feedback shaft and rope increase, which cause the raise of resistance and the decrease of landing velocity of escape person. Simulation and experiment show that the designed escape device is effective and safety.
