What is the term for developing a new product or system that has never existed?

The term for developing a new product or system that has never existed is invention. Invention specifically refers to the act of creating something entirely new, a novel idea or object that did not previously exist in any form. It involves original thinking and often leads to tangible outcomes, such as new devices, processes, or technologies. This process of invention is crucial in various fields, including technology and engineering, as it drives advancement and opens new possibilities.

In contrast, innovation typically relates to improving or making significant enhancements to existing products or systems rather than creating something entirely new. Creation is a broad term that can encompass various forms of generating ideas or items but does not specifically denote the novelty aspect inherent in invention. Design refers to the planning and structuring of existing concepts or products to enhance functionality or aesthetics but does not involve the aspect of producing something original. Therefore, the specific act of bringing something new into existence aligns most accurately with the concept of invention.
