Method for prefitting an orthotic member to the body

摘要

A method is provided for prefitting a stiffened member to a curved body having a geometry approximatable by a cone. Two points are initially selected on the surface of the body which also lie on two different planes passing through the body, such that the intersection of the surface and the planes defines two closed curves. A cone is approximated based on parameters relating to the curves and the selected points. A three-dimensional pattern of a stiffened member is then superimposed onto the conical surface at a modelling position corresponding to the desired placement position of the member on the body. The geometry and dimensions of the pattern are mathematically specified relative to the conical surface and the specifications provide a model for fabricating the prefitted stiffened member.
