Abstract
This paper presents the conceptual development of a biomechanically-compatible mobility device designed to assist medium-sized dogs with paresis of the hind limbs. The project, conducted within the scope of an undergraduate engineering design course, aimed to produce an affordable, lightweight, and sustainable solution through a structured and iterative design methodology. Four initial design alternatives were systematically evaluated using a weighted decision matrix, based on criteria such as comfort, ease of use, durability, cost, sustainability, flexibility, and aesthetics. The selected concept was further refined through CAD modeling and CAE-based structural analysis using the finite element method (FEM) to assess the mechanical behavior of candidate materials (namely PET, cardboard, bamboo, and silicone). Cardboard emerged as the most suitable material, balancing structural integrity, low cost, and environmental impact. Additional stability analyses were performed to evaluate the system’s performance on uneven terrain and under dynamic loading conditions. The study culminated in a detailed 3D model, technical drawings, and the construction of a functional prototype. The results validate the feasibility of designing assistive devices that are both biomechanically effective and environmentally conscious, offering practical benefits to animal welfare while promoting responsible engineering practice.
