Fostering Practical Engineering Skills Through Problem- Based Learning: A Scissor Lift Design and Automation Case Study

Abstract

This technical article introduces a pioneering educational approach that seamlessly melds Problem-Based Learning (PBL) with the practical development of a small-scale scissor lift. Encompassing the realms of design, simulation, and automation, the project offers students an immersive learning experience within the framework of a Machine Design course. By engaging in the conceptualization, design, prototyping, and automation of the scissor lift, students gain invaluable insights into the multifaceted dimensions of engineering practice. Problem-Based Learning serves as the foundational pedagogical strategy, encouraging students to collaboratively tackle real-world engineering problems. The scissor lift project becomes a microcosm of the engineering process, fostering critical thinking, teamwork, and communication skills. From the initial ideation and iterative design refinement to the application of Finite Element Analysis (FEA) to assess structural integrity, students learn to navigate challenges that mirror authentic engineering scenarios. The article delves into the pivotal role of simulation in refining the design's performance. By employing FEA tools, students gain competence in predicting mechanical behaviors, optimizing load distribution, and ensuring operational safety. The practical aspect of the project materializes during the prototyping phase, where theoretical designs transform into tangible prototypes. Load testing and iterative adjustments further imbue students with a hands-on understanding of engineering intricacies. Highlighting the contemporary relevance of automation, the project extends beyond conventional mechanical considerations. Arduino-based automation injects the element of control and precision into the scissor lift's operation.
