Designing is an essential activity to create products. The scope and activity of designing is different for various sorts of product, and some typical sorts of products are listed. Two extreme types of designing are compared. An example of conceptualizing in almost pure engineering design shows clearly that various abstract structures, models and methods can be used to enhance creativity, but the usual procedures of industrial design would not lead to such careful consideration of alternatives of construction.

‘Design’ can be a noun, or a verb. Six paths for research into engineering design (as verb) are identified, they must be co-ordinated for internal consistency and plausibility. Design Research tries to clarify design processes and their underlying theories – designing in general, and particular forms, e.g. design engineering. Theories are a basis for deriving theory- based design methods. Design engineering and artistic forms of designing, industrial design, have much in common, but also differences. For an attractive and user-friendly product, its form (observable shape) is important – a task for industrial designers, architects, etc. ‘Conceptualizing’ consists of preliminary sketches, a direct entry to hardware – industrial designers work ‘outside inwards’. For a product that should work and fulfill a purpose, perform a transformation process, its functioning and operation are important – a task for engineering designers. Anticipating and analyzing a capability for operation is a role of the engineering sciences. The outcome of design engineering is a set of manufacturing instructions, and analytical verification of anticipated performance. Design engineering is more constrained than industrial design, but in contrast has available a theory of technical systems and its associated engineering design science, with several abstract models and representations of structures. Engineering designers tend to be primary for technical systems, and their operational and manufacturing processes – they work ‘inside outwards’. Hubka’s theory, and consequently design metho- dology, includes consideration of tasks of a technical system, typical life cycle, duty cycle, classes of properties (and requirements), mode of action, development in time, and other items of interest for engineering design processes. Hubka’s methodology is demonstrated by several case examples.

<p class="2">This case study explores the opportunities for students of Industrial Design Engineering to engage with direct and indirect stakeholders by making their design process and results into open-ended designed solutions. The reported case study involved 47 students during a two-weeks intensive course on the topic of urban gardening. Observations were collected during three distinctive phases: the co-design phase, the creation of an open design, and the sharing of these design solutions on the online platform Instructables.com.</p><p class="2">The open sharing of local solutions triggered more global discussions, based on several types of feedback: from simple questions to reference to existing works and from suggestions to critiques. Also, some examples of <em>re-appropriation</em> of the designed solutions were reported. These feedbacks show the possibilities for students to have a global vision on their local solutions, confronting them with a wider and more diverse audience.</p><p class="2">The case study shows, on the other hand, the difficulty in keeping students engaged in this <em>global</em> discussion, considering how after a few weeks the online discussions dropped to an almost complete silence. It is also very difficult with such online platforms to follow the re-appropriation cycles, losing the possibility of exploring the new local context where the replication/modification of the designed product occurred. The course’s focus on open design is interesting from both the design and educational points of view. It implies a deep change in the teaching approach and learning attitude of students, allowing unknown peers to take part in the design process and fostering a global discussion starting from unique and local solutions.</p>

At RMC, in Mechanical Engineering, the third-year course MEE 303 ‘Principles of Engineering Design’ consists of 12 lectures and two mini-projects, one for redesign, and one for novel design. The redesign alternates between a water valve and an automotive oil pump. This case study is now up-to-date according to the most recent developments in the theoretical framework that is the basis for the systematic and methodical process. The search for solutions in this process involves creativity supported by systematic working.An automotive oil pump is to be redesigned for revised conditions. The existing oil pump originated from the 1970’s, and was used in a V-8 engine. A reconstituted set of engineering drawing was prepared. Using the recommended systematic procedure, and other appropriate methods, students were asked to perform the redesign process: to develop a design specification, to analyze the existing pump to detect organs and functions, to explore the solution field with a morphology, and to suggested an improved embodiment. The case study as presented here serves as a sample solution.

Multiple Case

In order to assess usability and impact of new Augmented Reality based prototyping technologies in industrial design engineering, we are carrying out a multiple case study. We focus on shortcomings in current (physical) prototypes and bottlenecks in the design process, which might present to cues for new Augmented Prototyping technologies. However, tracking and categorizing these bottlenecks is difficult, attention has to be given on the complete scope of prototyping use and its value towards design. A method was devised to capture bottlenecks in concept uttering, based on Critical Systems Thinking; identifying functionalist, interpretive, emancipatory, postmodern views tunes the researcher’s view to uses of advanced prototyping means that have impact on the complete design process.

Abstract There are growing efforts to mine public and common-sense semantic network databases for engineering design ideation stimuli. However, there is still a lack of design ideation aids based on semantic network databases that are specialized in engineering or technology-based knowledge. In this study, we present a new methodology of using the Technology Semantic Network (TechNet) to stimulate idea generation in engineering design. The core of the methodology is to guide the inference of new technical concepts in the white space surrounding a focal design domain according to their semantic distance in the large TechNet, for potential syntheses into new design ideas. We demonstrate the effectiveness in general, and use strategies and ideation outcome implications of the methodology via a case study of flying car design idea generation.

This paper introduces a new failure mode pattern of soil slope – the logarithmic spiral slippery fracture. A mathematical model for the logarithmic spiral slippery fracture is established, taking the anti-shear function of the soil-nailing into consideration. The shear of soil-nailing, axial force, and the safety coefficients based on the limiting equilibrium method are derived, leading to an accurate stability analysis of the strengthening of soil slope. A case study shows that the anti-shear function of the soil-nailing can be significant and should not be ignored in engineering design.
