Abstract

The invention discloses a 3D flatfoot correction insole design method based on arch data. The method comprises the following steps: S1, acquiring the parameters of characteristic foot parts of a human body; S2, determining coordinate axes of insole design according to the parameters of the characteristic foot parts; S3, determining the contour line of an insole in the coordinate axes; S4, according to the contour line of the insole, determining the parameters of an arch supporting part in the coordinate axes; S5, determining weft at the top of the insole; and S6, in the coordinate axes, generating an insole top surface and an insole bottom surface by using the contour line of the insole and the weft at the top of the insole line, generating insole side surfaces through lofting, and generating the 3D flatfoot correction insole according to the parameters of the characteristic foot parts and the parameters of the arch supporting part. The invention develops the design method for the arch part of the flatfoot correction insole based on the base point data of the arch of the human body and the man-machine ergonomic principle, and the radian of the arch supporting part of the correction insole is designed by taking the measured parameters of the human body as the basis and relying on a theoretical basis.

Description

technical field [0001] The invention belongs to the technical field of insoles, and in particular relates to a design method for 3D flat foot correcting insoles based on arch data. Background technique [0002] The design of orthopedic insoles for children with flat feet focuses on the shaping of the arch of the foot. Most of the existing flat foot correcting insoles are arch pads, that is, a support structure is added to the arch of the insole to reshape the arch of the foot of patients with flat feet. However, due to the collapse of the arch of the foot of patients with flat feet, when designing the corrective insole, it is necessary to construct the arch support according to the structural characteristics of the flat foot to restore the collapsed arch to normal. At present, patents and products related to flat foot corrective insoles only stipulate the height of the insole arch, but the human foot arch is a complex three-dimensional structure, and the arch support design...
