Abstract [en]

The compound nature of creativity entails the interplay of multiple cognitive processes, making it difficult to attribute creativity to a single neural signature. Divergent thinking paradigms, widely adopted to investigate creative production, have highlighted the key role of specific mental operations subserving creativity, such as inhibition of external stimuli, loose semantic associations, and mental imagery. Neurophysiological studies have typically shown a high alpha rhythm synchronization when individuals are engaged in creative ideation. Also, oculomotor activity and pupil diameter have been proposed as useful indicators of mental operations involved in such a thinking process. The goal of this study was to investigate whether beyond alpha-band activity other higher frequency bands, such as beta and gamma, may subserve divergent and convergent thinking and whether those could be associated with a different gaze bias and pupil response during ideas generation. Implementing a within-subjects design we collected behavioral measures, neural activity, gaze patterns, and pupil dilation while participants performed a revised version of the Alternative Uses Task, in which divergent thinking is contrasted to convergent thinking. As expected, participants took longer to generate creative ideas as compared to common ones. Interestingly, during divergent thinking participants displayed alpha synchronization along with beta and gamma desynchronization, more pronounced leftward gaze shift, and greater pupil dilation. During convergent thinking, an opposite pattern was observed: desynchronization in alpha and an increase in beta and gamma rhythm, along with a reduction of leftward gaze shift and greater pupil constriction. The present study uncovered specific neural dynamics and physiological patterns during idea generation, providing novel insight into the complex physiological signature of creative production.

Abstract [en]

This paper addresses the crucial need for engineering students to acquire both soft and hard skills for a successful career. While technical skills are essential, soft skills like communication, collaboration, problem-solving, leadership, and adaptability are equally vital. Traditional engineering education programs often neglect soft skill development, leaving students without structured guidance. This paper presents a strategic curriculum approach within an Industrial Design Engineering program that emphasises progressive skill development. It includes a competence profile and continuous self-assessment to encourage student reflection and growth. Additionally, a transformative process is introduced in a third-year capstone project, helping students identify and actively improve personal and interpersonal skills. The results underscore the importance of systematic soft skill development through reflective practice and assessment, offering valuable insights for engineering education.

Abstract [en]

Additive Manufacturing (AM) is often considered to increase opportunities for creativity in design compared to traditional manufacturing methods. At the same time, it is suggested that regulated work can have a negative effect on engineers’ creative abilities, which are linked to three components of creativity (expertise, motivation, and creative thinking skills). Due to the ‘newness’ of AM, engineers need to broaden their expertise to fully exploit their creative potential while using AM. Previous research has presented support tools to assist engineers to understand the complexity of AM. A majority of such studies focus on novice engineers, rather than providing an understanding of how AM is involved in industrial practices. This paper follows three case studies from the space industry, a regulated industry, that aims to re-design a product for AM over a 21-month time period. The purpose is to explore how restrictions affect engineers’ opportunities to build AM expertise for creativity in a regulated industry. Results show the importance that case-specific aspects have on an engineer’s learning path for adopting AM. Engineers find themselves in a complex situation, with a conflict between being ‘safe’ or innovative, where innovation within such regulated industries is often compared to innovating ‘in a box’.

Abstract [en]

Laser Powder Bed Fusion (LPBF) brings the possibility to manufacture innovative near-net-shape part designs. But unfortunately, some designed surfaces suffer from rough surface finish due to characteristics of the LPBF process. This paper explores trends in managing surface roughness and through a space industry case study, a proposed process that uses Additive Manufacturing Design Artefacts (AMDAs) is used to investigate the relationship between design, surface roughness and fatigue. The process enables the identification of design uncertainties, however, iterations of AMDA's can be required.

Abstract [en]

Design review (DR) is a product development (PD) activity used to inspect the technical characteristics of a design solution. Immersive virtual reality (IVR) technology enables the presentation of spatial information and interaction with 3D CAD models inside an immersive virtual environment (IVE). Such capabilities have shown the potential to mitigate the cognitive load needed for the visual perception of spatial information and, consequently, enhance design understanding and DR performance. Thus, an increasing number of studies have explored the effect of IVR technology on DR activities in different domains. However, determining when the implementation of IVR technology rather than a conventional user interface for DRs in mechanical engineering PD projects will be beneficial remains unclear. Hence, a conceptual DR experimental study was conducted to investigate the differences in the ability of engineering students to identify mechanisms and understand their functions when a design solution for a technical system is presented in an IVE by IVR technology and in a non-immersive virtual environment (nIVE) by a conventional user interface (monitor display, keyboard, and mouse). Data were collected by performing DR tasks and having participants complete a prior experience questionnaire, presence questionnaire, and mental rotations test. Findings of the study indicate that IVR does not support an enhanced ability of engineering students to identify mechanisms and understand their functions compared with a conventional user interface.

Abstract [en]

Personal and interpersonal skills are an essential part of design engineers’ knowledge and skills, which students rarely feel they work with in a structured way during their education. To improve soft skills, the ideas on developing students’ personal and interpersonal skills were implemented in design- implement experience, a 15 ECTS third-year capstone project for bachelor students. Parallel to the design project, students had to identify personal or interpersonal skills that they wanted to develop during the course. Personal development was done in several stages: Identification of personal development areas (PDA), discussion of PDA in group meetings, creating a development plan, personal coach meetings, status update and a final reflection 

The results of this paper are based on teachers notes, written documentation and course evaluations. In the analysis, development areas were categorised using the CDIO Syllabus 2.0, where 59% was classified as Personal skills and 40% related to Interpersonal skills. The perseverance subset was the most common one identified. Other areas included lack of self-confidence, conflict mediation, creating a constructive dialogue between team members and time and resource management. Using this approach for three years and analysing the implementation, we can conclude that it has improved students’ personal and interpersonal skills. The results also highlight that students like to be challenged to change their professional conduct.

Abstract [en]

One often-cited benefit of using metal additive manufacturing (AM) is the possibility to design and produce complex geometries that suit the required function and performance of end-use parts. In this context, laser powder bed fusion (LPBF) is one suitable AM process. Due to accessibility issues and cost-reduction potentials, such ‘complex’ LPBF parts should utilise net-shape manufacturing with minimal use of post-process machining. The inherent surface roughness of LPBF could, however, impede part performance, especially from a structural perspective and in particular regarding fatigue. Engineers must therefore understand the influence of surface roughness on part performance and how to consider it during design. This paper presents a systematic literature review of research related to LPBF surface roughness. In general, research focuses on the relationship between surface roughness and LPBF build parameters, material properties, or post-processing. Research on design support on how to consider surface roughness during design for AM is however scarce. Future research on such supports is therefore important given the effects of surface roughness highlighted in other research fields.
