Design paradigm

The term Design paradigm derives from the rather ambiguous idea of paradigm originating in Sociology of Science, which carries at least two main meanings:

As models, archetypes, or quintessential examples of solutions to problems. A 'paradigmatic design' in this sense, refers to a design solution that is considered by a community as being successful and influential. Usually success is associated to market share or some other measure of popularity, but this need not be the case. For instance, the eMate and other Apple Newton devices can be considered as paradigmatic because of their influence in subsequent designs, despite their commercial failure.

As Sociological paradigm, a design paradigm is the constellation of beliefs, rules, knowledge, etc that is valid for a particular design community. Here a paradigm is not a particular solution, but rather the underlying system of ideas that causes a range of solutions to be 'normal' or 'obvious'. A current example is the laptop: as of 2010 the design paradigm of laptops includes a portable computer unit consisting of a QWERTY keyboard, a hinged screen, etc. Moreover, such device is assumed to be helpful in tasks such as education as in the One Laptop per Child project.

While the first meaning of "design paradigm" refers to exemplary design solutions that create "design trends", the second meaning refers to what a group of people expects from a type of design solutions.

The term "Design paradigm" is used within the design professions, including architecture, industrial design and engineering design, to indicate an archetypal solution. Thus a Swiss Army Knife is a design paradigm illustrating the concept of a single object that changes configuration to address a number of problems.

Design paradigms have been introduced in a number of books including Design Paradigms by Warren Wake,^[1] and Design Paradigms by Henry Petroski.^[2] Architect Christopher Alexander's A Pattern Language^[3] is thought to have first popularized the term.

Design paradigms can be used either to describe a design solution, or as an approach to design problem solving. Problem solving occurs through a process of abstraction and characterization of design solutions, with subsequent categorization into problem solving types. The approach is akin to the use of metaphor in language; metaphors are used to help explain concepts that are new or unfamiliar, and to bridge between a problem we understand and a problem we don't. Design paradigms then can be seen as higher order metaphors; as the often three-dimensional distillation of a working relationship between parts, between groups of things, between the known and the unknown. In this sense, a bridge is a paradigm of the connection between the known and the unknown, and the functional equivalent of a physical bridge is consequently used in many fields from computer hardware to musical composition.

The design paradigms concept has proven so powerful in traditional fields of design, that it has inspired a branch of computer science, where computational analogies to design paradigms are commonly called design patterns. Importantly however, in design professions the term "design pattern" usually describes a 2-dimensional structure, whereas the term paradigm (or model) usually imply a higher order, having 3 or more dimensions.
