This paper examines current trends in foot prosthesis development, including a review of existing commercial and laboratory solutions. Based on the analysis, key limitations of current designs are identified high cost, maintenance complexity, and the lack of an active push-off phase in affordable models. The study presents a prototype of an adaptive foot prosthesis that does not rely on electric actuators or microcontrollers. The design incorporates an elastic element for energy return and a shock-absorbing sole made from foam material similar to that used in orthopedic sports footwear. Three-dimensional modeling was performed in SolidWorks, and structural analysis using the finite element method confirmed the mechanical integrity of the device under loads up to 1000 N. The results demonstrate the potential of passive, energy-efficient solutions for the development of affordable foot prostheses suitable for widespread use.

摘要

This paper examines current trends in foot prosthesis development, including a review of existing commercial and laboratory solutions. Based on the analysis, key limitations of current designs are identified high cost, maintenance complexity, and the lack of an active push-off phase in affordable models. The study presents a prototype of an adaptive foot prosthesis that does not rely on electric actuators or microcontrollers. The design incorporates an elastic element for energy return and a shock-absorbing sole made from foam material similar to that used in orthopedic sports footwear. Three-dimensional modeling was performed in SolidWorks, and structural analysis using the finite element method confirmed the mechanical integrity of the device under loads up to 1000 N. The results demonstrate the potential of passive, energy-efficient solutions for the development of affordable foot prostheses suitable for widespread use.
