The design process is driven by a structure known as the designer-client-user triangle Designer - conceptualizes and produces the product Client - person or group that wants the design conceived User - the person or group that will actually use the end product There are three parties involved in the design process The client first presents the project statement - the rest (design, production, consumption) all flows from here A design project statement is short and concise; it clarifies what the presenter wants from the designer Design is motivated by the client Where and When do Engineers Design? The designer and client have to understand what the users want in a design Users form the basis for the entire design process - In the end, it is the users who consume the product and whose needs have to be met The client must be able to understand the needs of the user/market and be able to communicate that to the designer User Client Designer Designers may be involved in a project where they focus only on producing a single part of a larger system - they need not be concerned by problems facing the general system Detailed design is where the procedures are thoroughly understood because the general design issues have already been resolved Conceptual design is a response to the project statement by investigating the size and mission of the product's design and identify the parameters and /or constraints Chapter 1: Engineering Design Chapter 1.2 - A Vocabulary Primer for Engineering Design Design - mental project in which means to an end are laid down Design - to conceive and plan out in the mind Designing is about people planning and creating ways to produce things that achieve some known goals Engineering design is a systematic process in which designers generate, evaluate and specify designs for devices/systems whose form and function achieve client's objectives and users' needs while satisfying a specified set of constraints Form cannot be deduced from function These may include drawings, blueprints that explain everything about the artefact Fabrication specifications enable implementation independent of designer's involvement Designs often produce unknown unknowns and ex post facto eval. criteria Communication is a key issue Design problems are ill structured when solutions cannot be found by applying mathematical formulas in a routine or structured way Open ended means designs have several acceptable solutions Engineering design: ill-structured, open-ended activity Chapter Design - an activity that produces a description of an artifice in terms of organization and functioning - its interface b/w inner and outer environments The design may be the only connection b/w the designer and fabricator Designer's intent must be clearly communicated to fabricator (Regency Hyatt House Accident) Chapter 1.4 - Evolution of Design Chapter 2: The Design Process
