From idea to invention

Although a new or useful object or method may be developed to fulfill a specific purpose, the original idea may never be fully realised as a working invention, perhaps because the concept is in some way unrealistic or impractical.

A "castle in the air" or a "pie in the sky" (or "castles in Spain") may refer to a creative idea which does not reach fruition due to practical considerations. The history of invention is full of such castles, as inventions are not necessarily invented in the order that is most useful. For example, the design of the parachute was worked out before the invention of powered flight. Other inventions simply solve problems for which there is no economic incentive to provide a solution.

On the other hand, any barriers to implementation may simply be an issue of engineering or technology which can be overcome in time with scientific advances. History is also replete with examples of ideas which have taken some time to reach physical reality, as demonstrated by various ideas originally attributed to Leonardo da Vinci which are now expressed in everyday physical form.

Invention and innovation

Following the terminology of political economist Joseph Schumpeter, an invention differs from an innovation. While an invention is merely theoretical (even though the legal protection of a patent may have been sought), an innovation is an invention that has been put into practice. However, this conflicts with the theory of social anthropologists and other social sciences researchers. In social sciences, an innovation is anything new to a culture. The innovation does not need to have been adopted. The theory for adoption (or non-adoption) of an innovation is called diffusion of innovations. This theory, first put forth by Everett Rogers, considers the likelihood that an innovation will ever be adopted and the taxonomy of persons likely to adopt it or spur its adoption. Gabriel Tarde also dealt with the adoption of innovations in his Laws of Imitation.
