1551 results about "Modular design" patented technology

Modular design, or "modularity in design", is an approach (design theory and practice) that subdivides a system into smaller parts called modules or skids, that can be independently created and then used in different systems. A modular design can be characterized by functional partitioning into discrete scalable, reusable modules; rigorous use of well-defined modular interfaces; and making use of industry standards for interfaces. In this context modularity is at the component level, and has a single dimension, component slottability. A modular system with this limited modularity is generally known as a platform system that uses modular components. Examples are Auto platforms or the USB port in CE platforms.
