Abstract Today, engineering designs are tackling projects of increasing complexity and cost. The constraints are getting more complex, there are new materials and processes to exploit and stricter regulations and legal requirements to satisfy. Making products more quickly and efficiently is even more important in these times of increasing economic competition. Over recent years, use of computer tools in the design-analysis-manufacture stages has led to decreased lead times and reduced product costs. In particular, in the engineering design process, it has become clear that more extensive computer based support tools would result in greater gains. These include tools that help the designer maintain consistency in the design representation, help in documentation of information such as design intent, perform knowledge based manufacturing analysis and help in the generation of intelligent manufacturing plans. Progress has been made in the representation of design entities, as can be seen, for example, in geometric modeling. However, as this article point out, the techniques and methodologies underlying current Computer-Aided Design (CAD) systems are an insufficient basis for realizing automation of the engineering design process. This article proposes that an integration of Artificial Intelligence (AI) techniques with geometric modeling systems can better meet the requirements of Computer-Aided Engineering (CAE) design practice.

The article shows that the study of design process as a special activity in graphic design is an art history problem and requires special research methods. It is scientific methodology that makes it pos-sible to achieve reliability in art history knowledge. Attention is drawn to the fact that since the 1960s the methodology of systems theory and activity theory has been a keynote for the development of the design process knowledge in various schools of graphic design. This methodology meets academic criteria and has not lost its value in our days. Based on the principles of this methodology the article analyzes different types of the graphic design process. The objective processes associated with the use of computer technologies in design appear to be the norm and the paradigm of functioning in modern graphic design. Thus, the idea of existence of numerous computer-aided design types is justified. The design objectives of diverse complexity serve here as criteria. On the basis of these objectives traditional, original, and innovative designs are out-lined and comparatively analyzed in the article. It is noted that computer technologies, first, act as an effective tool for the implementation of the forms envisioned by the designer. Second, a computer can be regarded as a creative partner, an agent. Computer technologies possess a unique set of properties and features that open up new opportunities for a creative practice in the field of graphic design. The boundaries of the design practice are changing, and new areas of collective creativity are being estab-lished. In this case the graphic design process is a process that involves efforts of many people. So, individual creativity of professional designers appears to be replaced by the collaboration of interdisci-plinary experts. It is also noted that the growth of computer-aided technologies is too fast for graphic designers to develop a theoretical understanding of them. It results in the duality of assessing the role of methodol-ogy and experience in the graphic design process. On the one hand, the use of design methodology improves efficiency of the design process in comparison with the approach based on experience. On the other hand, there occurs the “extraction” of methodology from the design practice. Research meth-ods of the graphic design process are created under the influence of not only intradisciplinary process-es but also with a view to the messages from other areas of academic knowledge. An example is the use of synergy as a special way of understanding empirical facts accumulated in various fields of aca-demic knowledge. Namely, computer-aided design reveals the non-linearity, a large variety of forms. Herewith, any calculations applied to a huge number of graphic elements change the visual result, creating a new version of the form. It is noted that the use of high-tech computer technologies is quite specific about training designers.

In recent years, there has been a significant push towards “Design for X” (DFX) in modern engineering design practice. One such category that has received a large amount of attention is design for manufacturing. When conducting design for manufacturing, a common tool to assist in the design process is design for a series of design for manufacturing guidelines. While the use of these guidelines, as well as other DFX guidelines, has been shown to be effective, little research has been done with the intent to standardize the guidelines or make them more readily available. In this paper, the authors propose a Design for Manufacturing database tool to assist in the instruction of design for manufacturing guidelines. The development of the database model is discussed, as well as the interface that is used to interact with the database. The tool is then evaluated and conclusions are made with regards to the effectiveness of the database and any future work to increase the functionality. One major addition that is discussed is the adaptation of the database for use in industry, and not just in education, to assist in the engineering design process.

Purpose The purpose of this study is to examine a week-long science, technology, engineering and mathematics (STEM) project-based learning (PBL) activity that integrates a new educational technology and the engineering design process to teach middle and high school students the concepts involved in rotational physics. The technology and teaching method described in this paper can be applied to a wide variety of STEM content areas. Design/methodology/approach As an educational technology, the dynamic and interactive mathematical expressions (DIME) map system automatically generates an interactive, connected concept map of mathematically based concepts extracted from a portable document format textbook chapter. Over five days, students used DIME maps to engage in meaningful self-guided learning within the engineering design process and STEM PBL. Findings Using DIME maps within a STEM PBL activity, students explored the physics behind spinning objects, proposed multiple creative designs and built a variety of spinners to meet specified criteria and constraints. Practical implications STEM teachers can use DIME maps and STEM PBL to support their students in making connections between what they learn in the classroom and real-world scenarios. Social implications For any classroom with computers, tablets or phones and an internet connection, DIME maps are an accessible educational technology that provides an alternative representation of knowledge for learners who are underserved by traditional methods of instruction. Originality/value For STEM teachers and education researchers, the activity described in this paper uses advances in technology (DIME maps and slow-motion video capture on cell phones) and pedagogy (STEM PBL and the engineering design process) to enable students to engage in meaningful learning.
