Conceptual Design of a Hard-Shell Rooftop Camping Tent

In this study, the conceptual design of Hard-Shell Rooftop Camping Tents (HSRCTs) was carried out to address the growing demands in the camping industry. HSRCTs offer an innovative solution for campers with features such as portability and durability. The study systematically addressed the conceptual stages of the design process. The fundamental steps of conceptual design included creating a list of requirements, preparing function diagrams, determining design variations, and selecting the most suitable option.<br>The list of requirements encompassed key features of HSRCTs, such as geometry, materials, vehicle fuel consumption, ergonomics, manufacturing, and assembly, classifying these requirements as either mandatory or optional. For example, features such as being lightweight and durable, easy to open and close, and suitable for four-season use shaped the design criteria. The function diagram identified sub-functions by associating user needs with product outcomes. During this process, criteria such as material selection, ease of production, and assembly methods were detailed.<br>Morphological charts were used to develop various material and assembly alternatives during the solution search. For instance, ABS material emerged as an ideal option due to its lightweight nature and cost advantages. Selection charts and evaluation tools were employed to conduct a preliminary assessment of the design alternatives. Based on these evaluations, the design variant utilizing ABS material, known for its lightweight, durable, and easy-to-manufacture characteristics, was determined to be the most suitable option. This conceptual design phase established a robust foundation for the aerodynamic analysis of HSRCTs.<br><br>
