Abstract
Even today, many people around the world, that need artificial limbs, do not have access to them. This is mainly because of the high cost associated with the design and production of artificial limbs. One critical key factor that contributes to the cost of the production of artificial limbs is the complete customization of shapes and proportions to each individual patient. Automating this process could substantially reduce the cost of producing artificial limbs. In this paper we utilize the API (Application Programming Interface) of a commercial CAD-based system to automate the three-dimensional design of prosthetic lower limbs. First, the essential design parameters for the automation process are defined. These parameters are mainly based on human physiology and the traditional design and fabrication techniques of artificial lower limbs. Then, the system, based on the values assigned to the input parameters, automatically creates customized prosthetic lower limbs. In addition, the system offers various design alternatives based on the intended use of the artificial limb. The CAD-based System presented in this paper highlights the feasibility of comprehensive parameterization in the prosthetic limb design process, which harbors significant potential for shaping future developments in prosthetic limb design. Beyond technical considerations, it also holds promise for positively influencing cost dynamics and improving accessibility within this critical domain.
