Design Considerations
Design considerations refer to the factors and elements that must be taken into account when creating a product, system, or solution. This includes aspects such as functionality, aesthetics, usability, cost, materials, and environmental impact. By carefully considering these factors during the design process, engineers and designers can create more effective and efficient solutions.

Therefore, we can define engineering design as follows. Engineering design is the use of scientific principles and technical information in the creative development of a plan to bring about a man-made product to achieve a prescribed goal with certain specified constraints. The consequence of the implementation of the design will bring changes to the environment, while the environment of the designer influences the design itself. Software design is a branch of engineering design where the product to bring about is software. Figure 1.5 Basic concepts of design As depicted in Figure 1.5, design activities have the following characteristics. Design starts with a need and requires intention. It results in a scheme for implementing an artefact. It involves transformations and the generation of new ideas is fundamental to all designs. Design is goal directed problem solving and decision making. It must satisfy the constraints and the requirements. The design Scheme for implementing an artefact Objectives Description of product Rationales Plan of production Usage A need or The problem to be solved Constraints on the solution Design Process Transformation Development Creation Problem solving Decision making Constraint satisfaction Constraint discovery Navigation in design space Diversity Evolution 22 Chapter 1. Basic Concepts of Design process is also a constraint discovery process. Design is to achieve optimality in a solution space of diversity; hence, it is often an evolutionary process. An engineering design should contain at least five basic elements: (a) the objectives of the design, (b) a description of the designed product, (c) the rationale of the design, (d) a plan of the production, and finally, (e) the designated usage of the product. There are a number of factors that effect design processes and their outcomes.

In the engineering literature, technical designing is sometimes placed in an even broader context, which brings us to the second feature of designing mentioned at the beginning of this chapter. The customers are frequently commercial companies – many engineers are traditionally employed by such companies – which means that the vested interests of those companies, in the form of commercial success and economic continuation, become integral aspects of the goals that have to be achieved during the design process.Technical designing thus also becomes, in part, a form of product design for economic markets; the designing engineer must create artefacts that can be marketed and must innovate technologically so that companies and national economies can grow. As well as this commercial aspect of technical designing, there is also a social aspect that needs to be considered. Governments also commission projects: for instance, in order to serve society engineers design airports, air traffic control systems and military aircraft. Engineers are service providers who set out to help people, companies and society to realise their goals and to resolve their problems. Engineers thus have great economic and social influence both in positive and negative ways. People can travel by air, but aeroplanes can also crash and have a major impact on, for example, those who live near airports and upon the environment. As such, technical designing is also becoming, to an increasing degree, a process of designing for demands and needs in the areas of ethics, safety, the environment and sustainability. This wealth of different characterisations makes philosophical reflections on technical design- ing similarly multifaceted. In the present chapter, we shall provide a philosophical reconstruction of technical designing where the main focus throughout will be on the core activity. In the next chapter, we shall go on to discuss the ethical aspects of technical designing.

It is worth noting that the pace in an engi- neering design office is driven by the available billable hours. Engineering design is tightly con- strained by the time available to get the job done. If the billable hours are limited (and they always are), then tough decisions must be made, and some of the idealized steps described here are abbreviated— or even eliminated. ❚ NEEDS ASSESSMENT The engineering design process starts with the recognition of a need that can potentially be sat- isfied using technology. In many cases, needs are Formulation phase Concept design phase Configuration design phase Detail design phase Figure 1-5 Engineering design phases 8 Adapted from Eide. CHAPTER 1 ENGINEERING DESIGN 6 identified not by engineers but rather by actual users, sometimes with the assistance of experts. See Chapter 2 for additional information on the user’s role in the design process. Potential clients may also approach design firms with a specific need. In a large manufacturing company, the sales or marketing department maintains contact with its customer base and identifies many of these needs. In a more systematic approach, product ideas are generated by a product planning group. Needs arise for a variety of reasons, including (1) a product redesign in order to make it more profitable or effective, (2) the establishment of a new product line, (3) a need to protect public health and safety or to improve quality of life, (4) an invention, often by an individual, that is then commercialized, (5) opportunities created by new technology or scientific advances, and (6) a change in rules, requirements, or the like. The outcome of the needs assessment is a list of needs or requirements, which then becomes a part of the problem definition. ❚ PROBLEM DEFINITION Once a list of needs has been developed, the next step in the design process is to clearly and carefully formulate the problem to be solved.
