This book is the result of lessons, tutorials and other laboratories dealing with applied mechanical design in the universities and colleges. In the classical literature of the mechanical design, there are quite a few books that deal directly and theory and case studies, with their solutions. All schools, engineering colleges (technical) industrial and research laboratories and design offices serve design works. However, the books on the market remain tight in the sense that they are often works of mechanical constructions. This is certainly beneficial to the ordinary user, but the organizational part of the functional specification items is also indispensable.

Case Study-based Design Methodology

1.1. Methodology for designing a project product

“Methodology” should be taken to mean the preparation of an exhaustive file of the steps that must be followed at a research center. That file will contain the data defining the product, right down to the expression defining the need for it.

Figure 1.1. Scientific approach to design

The scientific approach is named as such because of the dissatisfactions pertaining to fields not explored by the core sciences. If the subject is unique or original, in collaboration between multiple disciplines, new hypotheses may be formulated and patented. Thus, the state of the art will be enriched.

Figure 1.2. Process of a design project

Given the multi-disciplinarity (fields of mechanics, pneumatics, hydraulics, electronics, etc.) of subjects which encapsulate design and vast domains of application (the manufacturing industry, agriculture, civil and/or military construction, biomechanics, automotive engineering, aeronautics, etc.) in this book, we present examples found in systems in mechanical and civil engineering. The mathematical foundations are common to the two domains, but the behavior of the materials and structures sometimes differ.

We can already see that design is hugely complex. A designer must have good knowledge of numerous branches of science and technology, in addition to a keen sense of the dual organization of good intuition. The project approach is less stressful because the client will have clearly expressed their requirements at the outset. Solutions will be put forward with the aim of satisfying the requirements, in connection with the technical and economic feasibility. Once the designer has accepted the project to conduct manufacturing studies, tests will be carried out. If the result is a conclusive approval, then the product will be made and potentially released to the public.

1.2. Main players involved in the design process

Design projects are studied in a research hub (RH). Thus, the RH is an entity which is often complex, the size of which is subject to variation from one company to another. The teams employed at RHs are multi-disciplinary, complementary and diverse. The tasks are often trivial and overseen by: the study engineer; the study designer and the projector.

The research engineer is the head of the research project, but delegates some of the work to the projector. In addition to the calculations for which s/he is responsible for (graphic design, core sciences and applied sciences), the research engineer acts as an interface between the administrative and financial management teams.

The study designer, despite what the title suggests, actually deals with more than just designs. His/her role is to finalize the defining designs and drawings in the preliminary stage of the project.

The projector, as the etymology indicates, assists the research engineer in projecting technical tasks, including the defining design drawings. Depending on the structural organization of each company, the projector may sometimes deal with clients, with suppliers and with all the company’s separate departments. In addition to t...
