Method and system for brace designing. The method comprises the following steps: S1) fixing a subject requiring a brace； S2) acquiring skeletal image information of the subject； S3) determining an adjustment solution for implementing an adjustment with respect to the subject and a target state that is to be achieved ultimately； S4) adjusting the subject to alter the skeletal structure of the subject； S5) acquiring adjusted skeletal image information of the subject； S6) determining whether the skeleton of the subject has been adjusted to the target state； if yes, then terminating adjustment and entering step S7； if not, then returning to step S4； S7) acquiring the body surface three-dimensional shape of the subject having achieved the target state and recording information of the force applied by an adjusting head to the subject for use in manufacturing a corresponding brace； thus allowing the highly efficient designing of a brace.
