keretalapú
Keretalapú is a Hungarian term that translates to "frame-based" in English. It refers to a fundamental concept in design and engineering, particularly in the construction of vehicles, buildings, and furniture. A frame-based structure is characterized by a supporting skeleton or framework made of interconnected components, such as beams, columns, or struts. This framework carries the primary loads and provides rigidity to the overall structure. In contrast to monolithic designs where the entire object is a single, solid piece, keretalapú structures rely on the arrangement and connection of these individual elements. The advantages of this approach often include greater strength-to-weight ratios, easier assembly and disassembly, and the flexibility to adapt the design to various shapes and sizes. For example, a car chassis is a classic example of a keretalapú design, where the frame supports the engine, body, and occupants. Similarly, many modern buildings utilize steel or concrete frames as their primary structural system. The term emphasizes the foundational importance of the underlying structure in defining the object's form and function.
