Brand
A brand is a name, term, design, symbol, or other feature that distinguishes an organization or product from its rivals in the eyes of the customer. Brands are used in business, marketing, and advertising. Name brands are sometimes distinguished from generic or store brands.
Design
Design is the creation of a plan or convention for the construction of an object, system or measurable human interaction (as in architectural blueprints, engineering drawings, business processes, circuit diagrams, and sewing patterns). Design has different connotations in different fields (see design disciplines below). In some cases, the direct construction of an object (as in pottery, engineering, management, coding, and graphic design) is also considered to use design thinking.
Innovation
Innovation can be defined simply as a "new idea, device or method". However, innovation is often also viewed as the application of better solutions that meet new requirements, unarticulated needs, or existing market needs. Such innovation takes place through the provision of more-effective products, processes, services, technologies, or business models that are made available to markets, governments and society. The term "innovation" can be defined as something original and more effective and, as a consequence, new, that "breaks into" the market or society. Innovation is related to, but not the same as, invention, as innovation is more apt to involve the practical implementation of an invention (i.e. new/improved ability) to make a meaningful impact in the market or society, and not all innovations require an invention. Innovation often manifests itself via the engineering process, when the problem being solved is of a technical or scientific nature. The opposite of innovation is exnovation.
Design
This is exactly the meaning of design: the conflict between form and content, form being the problem. [...] It is the coming together of form and content that is the realization of design.
Paul Rand (2008), Conversations with Students p. 32
Design
If the chief rules of good design were understood by the masses as they might be, nothing would do more to promote beauty, improve workmanship, add to the value of manufactures, and in many other ways further the general welfare and prosperity of the country. They are simple, easy to acquire, and should be taught with the alphabet.
Ernest Flagg, Small Houses: Their Economic Design and Construction (1922)
Design
I think so many of the objects we're surrounded by seem trivial. And I think that's because they're either trying to make a statement or trying to be overtly different. What we were trying to do was have a very honest approach and an exploration of materials and surface treatment. So much of what we try to do is get to a point where the solution seems inevitable: you know, you think 'of course it's that way, why would it be any other way?' It looks so obvious, but that sense of inevitability in the solution is really hard to achieve.
