The algorithm can classify image datasets, CAD datasets, and combined da...

Machine vision systems for automatic defect detection commonly adopt 2D image-based systems or 3D laser triangulation systems. 2D and 3D systems present opposite advantages and disadvantages depending on the typology and position of defects to be detected. When the variety of defects is large, none of them performs defect detection accurately. To o...

Sustainability evaluations are increasingly relevant in the design of products. Within sustainability-related frameworks, circular economy (CE) has gained attention in the last few years, and this has vastly affected design, leading, for example, to design for circularity. This article deals with the wide range of product-level CE assessment tools,...

Thus, AD helps to evaluate the usability of the design or the user interface, although t...

This study examines the perception of cognitive fluency of products in accordance with the Fluency Amplification Model. An experiment was conducted to compare the differences in product evaluations between two types of product representations, a tangible product and an image thereof, each assigned to a different group of participants. The results s...

The rapid development of production methods and the introduction of additive manufacturing (AM) technologies have increased the design freedom and availability of unlabeled data.

These outcomes are achieved through a literature review on how UX relates to design. First, issues in b...

In marketing, the need to make products’ packages as much attractive as possible is generally acknowledged as one of the leading assets. However, art designers also aim to surprise people and often break previous assumptions. In 2020, Kunel Gaur has produced a series of “dystopian” images of globally famous brands, by following the principles of mi...

Since its inception, research on design methods has encompassed a number of objectives and fields. In this fragmentary and evolving landscape, a reflection was apparently needed on the chance to provide a general framework and understand the progress (if any) towards a unified and domain-independent design theory and methodology. The issue was disc...

Empirical studies based their experimental activity on HCI products, which are characterized by two components: Software and intangible (digital interfaces and web apps) a...

Eco-designed products can contribute to sustainable development if consumers choose them rather than the less environmentally friendly alternatives and if they are used properly. However, eco-design methods have so far failed to address the issue of unsustainable behaviors, whose sources have not been recognized. In light of this deficiency, the au...

The terms that constitute Ideality in TRIZ are extremely appropriate to characterize the conflicting prerogatives of value/functionality, and environmental sustainability and human wellbeing. In a system perspective, the latter are mostly ascribable to harmful functions and consumption of resources. The paper introduces a classification of sustaina...

To support the transition to sustainable development, eco-design must lead to the development of products that provide additional value when compared to traditional products, ultimately resulting in market success. In this study, creativity principles are explored as leverage points for eco-design implementation, enhancing customer acceptance and m...

The concept of Design for Additive Manufacturing (DfAM) is gaining popularity along with AM, despite its scopes are not well established. In particular, in the last few years, DfAM methods have been intuitively subdivided into opportunistic and restrictive. This distinction is gaining traction despite a lack of formalization. In this context, the p...

The concept of User Experience (UX) dates back to the 1990s, but a shared definition of UX is not available. As design integrates UX, different interpretations thereof can complicate the possibility to build upon previous literature and develop the field autonomously. Indeed, by analysing the literature, UX emerges as a cauldron of related and clos...

The term User Experience (UX) was introduced to define the dynamics of the human-product interaction, and it was thought that design would have been a main recipient of UX research. However, it can be claimed that the outcomes of UX studies were not seamlessly transferred into design research and practice. Among the possible reasons, this paper add...

Although the circular economy (CE) concept is gaining traction and methods to assess companies’ CE-related aspects exist, there is no established CE assessment tool. In many cases, it is not clear how metrics or indicators included in extant CE assessment methods have been selected. To fill this gap, this paper presents a new instrument named Circu...

On the one hand, many mechanical components manufactured through additive technologies are optimized in terms of stiffness/weight or strength/weight thanks to lattice structures. On the other hand, the high complexity of these components often impedes further finishing operations and, therefore, the fatigue strength can be compromised. The high sur...

Shortcomings in manufacturing companies’ capabilities to execute circular economy business modelling have delayed a broader dissemination of circular business models beyond the stage of pilot projects in niche markets. Circular economy poses additional uncertainties for innovation that are not common for manufacturing companies’ traditional activit...

The market for agricultural machinery is characterized by products with a high degree of maturity in the product life cycle. Consequently, current improvements in new machinery are predominantly incremental and new projects basically use solutions that are already consolidated. This makes this domain appropriate for benchmarking existing systems an...

Idea generation is acknowledged to benefit from intentionally administered stimuli or designers’ processes that include the search for external sources of inspiration. Text-based and graphic forms of stimuli are the most leveraged in design literature, but it has not been yet demonstrated which form is most effective for boosting creativity. This i...

The definition of a comprehensive initial set of engineering requirements is crucial to an effective and successful design process. To support engineering designers in this non-trivial task, well-acknowledged requirement checklists are available in literature, but their actual support is arguable. Indeed, engineering design tasks involve multifunct...

Eco-Design Strategies lead to both enhanced environmental sustainability and product differentiation, which, however, takes place only if observers recognize and value these advantages. To study this aspect, a sample of 40 product pictures has been administered to 12 subjects with experience in eco-design. They were asked to evaluate whether one or...
