What Is Engineering Design? What Steps Make Up the Design Process Cycle?
Engineers, who develop the structures, tools, and machines that meet people’s needs in every area of life, work systematically and focus each project on a specific need. Design plays a critical role in turning this systematic work into results and achieving high efficiency.
Engineering design means much more than a workable idea. The design process works through many different scenarios and steps with the aim of delivering the best possible outcome for investors and users. External factors also shape engineering design: a design’s functionality and its physical and financial constraints have a significant impact on how it is developed. At the same time, the competitive conditions in the relevant field strongly influence the decisions made along the way. A creative idea, the right conditions, and an effective presentation are essential for an engineering design to meet expectations and for the process to be completed successfully.
What Is Engineering Design?
Engineering design is a concept that covers all of the practical and theoretical work carried out systematically to meet a specific need. It is much more than a set of designs developed simply to solve a problem. Designs developed after a problem has been clearly identified can deliver results that make a real difference. The scope and presentation of a design are key to demonstrating its functionality. In addition, a number of criteria come into play when designs are approached from an engineering perspective.
Designs that result from applying engineering skills where they are needed must meet certain criteria when evaluated from an engineering perspective. Even if an idea is practical, it is unlikely to be implemented if factors such as the total cost of the design, its production phase, and its competitiveness do not reach the required level. Engineering design is generally developed in accordance with international standards and subjected to established reliability tests.
What Steps Make Up the Design Process Cycle?
The decisions made throughout the engineering design process cycle are crucial to taking the right steps. For the design process to progress successfully, visual, verbal, and written communication is essential. Different disciplines use these communication methods to contribute to analysis, development, and testing. The steps from identifying a problem to reaching the final design outcome are as follows:
+ The first step in the design process is identifying the need. A design can only begin once a need exists and has been defined in general terms. This stage is crucial for addressing the problem correctly.
+ Once the need has been identified and defined, concept design follows. Solution-oriented research gives rise to initial draft ideas. At this stage, more than one design is usually put forward.
+ Engineering design allows designers to define the boundaries of their work. The competitive cost is shaped by the decisions of the design team. The estimates made at this point should meet the requirements of the design, and decisions should be made accordingly. Sufficient and reliable information is needed to make realistic estimates.
+ The next step in the process cycle is mathematical modeling. This step examines manufacturability and identifies the most suitable approaches. Engineers also carry out optimization and analysis at this stage, before physical production begins.
+ In prototype design, the final step of the process, the requirements are evaluated using mathematical modeling. Following this evaluation, the prototype is produced and the necessary tests are carried out.
