Parametric custom design of insoles based on 3D foot shape and plantar pressure distribution
To reduce peak plantar pressure,enhance the comfort of insole products,and prevent foot-related diseases,a process for designing parametric,customized,porous insoles was proposed.This process was driven by a three-dimensional foot model and plantar pressure distribution.First,a method was constructed for the automatic generation of highly adaptive insole models using the user's three-dimensional foot model and relevant foot dimension parameters.Secondly,an image sampling algorithm was employed to establish a mapping point set for the distribution of plantar pressure on the user's foot to the spatial density distribution in the insole.This served as the foundational data for generating spatial unit structures within the defined domain of the insole model through the Voronoi 3D tool.Finally,Voronoi skeletal lines adapted to the insole model's boundary were extracted,and a porous insole mesh model was established by integrating a mesh generation algorithm.Dynamic and static plantar pressure experimental results indicated that,compared to traditional insoles,porous insoles designed based on foot shapes and pressure distribution could effectively reduce peak plantar pressure,increase the contact area on the plantar surface,and improve the symmetry of pressure distribution between the left and right feet.
