The current study proposes the innovative concept of gravity balance and dynamic efficiency for developing a energy saving walking assisting device for the people hard to walk themselves. The problems encountered by developing and developed countries getting serious labor shortage and increasing of old age society. A walking assisted mechanism are that can help people easy to walk or move heavy load is thus to be a focus topic of the study. First of all, we searched and surveyed the products on the current market to define the need of the design object. Second, we use the design theory: TRIZ to define our design direction with two targets. Those are this mechanism can keep user in stable at anytime and energy saving. Following the design targets, we propose a two legged walking assisted device for the experimental model of this thesis. The spring were adopted to implement the gravity balance force. The coefficient of the spring has been calculated and designed to generate a potential energy function without the angle variables. The total potential energy thus becomes a constant. Then, we develop a program to evaluate the effect of energy saving at Dynamic status for deriving or better design of the walking assisting device. We hope this study conclusion and design prototype can be improved and developed into a new two-legged walking assisted design platform, and help to initiated many new developed easy to use assisting device to reach a more happy and healthy society in the future.
