The engineering design process, also known as the engineering method, is a common series of steps that engineers use in creating functional products and processes. The process is highly iterative – parts of the process often need to be repeated many times before another can be entered – though the part(s) that get iterated and the number of such cycles in any given project may vary.
Iterative design is a design methodology based on a cyclic process of prototyping, testing, analyzing, and refining a product or process. Based on the results of testing the most recent iteration of a design, changes and refinements are made. This process is intended to ultimately improve the quality and functionality of a design.
The design process is plan-driven. The design process is understood in terms of a discrete sequence of stages. The rational model is based on a rationalist philosophy [12] and underlies the waterfall model, [19] systems development life cycle, [20] and much of the engineering design literature. [21]
Industrial design is a process of design applied to physical products that are to be manufactured by mass production. [ 1 ] [ 2 ] It is the creative act of determining and defining a product's form and features, which takes place in advance of the manufacture or production of the product.
In chemical engineering, process design is the choice and sequencing of units for desired physical and/or chemical transformation of materials. Process design is central to chemical engineering, and it can be considered to be the summit of that field, bringing together all of the field's components.
The process is characterized by the alternation of divergent and convergent thinking, typical of design thinking process. To achieve divergent thinking, it may be important to have a diverse group of people involved in the process. Design teams typically begin with a structured brainstorming process of "thinking outside the box". Convergent ...
Process engineering activities can be divided into the following disciplines: [7] Process design: synthesis of energy recovery networks, synthesis of distillation systems (), synthesis of reactor networks, hierarchical decomposition flowsheets, superstructure optimization, design multiproduct batch plants, design of the production reactors for the production of plutonium, design of nuclear ...
Moreover, design changes may be also made mandatory by updates in laws and regulations. The design process is an information intensive one, and design engineers have been found to spend 56% of their time engaged in various information behaviours, including 14% actively searching for information. [1]
