“…During the creative process, designers usually recur to several sources of inspiration to seek analogies from different domains and with the aim of obtaining inspiration. In this sense, two relevant aspects widely studied in this field are "fixation" and "inspiration", showing some studies how the use of examples facilitates the generation of novel and high-quality ideas [56][57][58][59].…”

Optimization of the Aesthetic Design of an Agronomic Product Inspired by an Asymmetric Shape of Water

Industrial products have been highlighted in the agronomic field more for their technical and functional aspects than for their visual aesthetics. Currently, this concept has changed and has favoured the development of innovative products taking into account all the factors involved in the conception of a product. This article describes a real industrial product redesign case that was functionally innovative and a reference in the agronomic domain. Due to the large number of copies that emerged from its competitors, this design required a new image in its aesthetic appearance to differentiate it from the rest. The difficulty of this project lay in the technical limitations to develop it, so a conceptual design process based on analogies and inspired by nature was necessary to find the most appropriate shape. Based on this methodology, a symmetrical and static design was transformed into one with asymmetrical and dynamic shapes inspired by the helicoidal movement of water. This new design gave this product an innovative, symbolic, and differentiating image that allowed its industrial registration in a large number of countries.

“…The main phases of the systematic design process followed in this work can be schematically represented by Figure 7, where it is possible to observe that the conceptual design process can be furtherly split in three sub-phases (Fiorineschi, 2018;Fiorineschi et al, 2016). It is worth to notice that even if not represented in Figure 7, the overall design process is highly iterative, and then several iterations are expected among the different design phases (Pahl et al, 2007).…”

“…Recently, a new conceptual design approach has been proposed in literature, which is claimed to overcome the limits of Functional Decomposition and Morphology, by exploiting the systematic tracking of problems and solutions co-evolutions of the concept alternatives generated during the design process (Fiorineschi et al, 2016). The approach is based on six fundamental rules, which allow the generation of a structured network of problems and solutions, which can be conveniently used for managing the design space exploration and to overcome design fixation, especially if predefined abstraction frameworks are adopted (Fiorineschi, 2018). It is constituted by three main phases that substantially provide a further nested subdivision of the overall systematic design process (Figure 7).…”

Purpose The purpose of this study is to identify an innovative solution for the power transmission gearbox of concrete mixers, according to the specifications provided by the company. Design/methodology/approach A tailored systematic design approach (inspired to the German systematic framework) has been adopted to comprehensively gather the company specifications and perform in-depth design space explorations. Subsequently, an iterative embodiment design approach has been followed to identify the size of the components for the preferred concept, by using acknowledged mechanical design procedures and finite element analysis tools. Findings An innovative cycloidal gearbox has been developed, by merging the kinematics underpinning the classical cycloidal drives and the Wolfrom planetary gearbox. The resulting concept provides high reduction rates with a very high overload capacity. Research limitations/implications The main limitation of the studies is the absence of in-depth evaluations usually performed in the detail design phase. However, this limitation is a direct consequence of the company specifications, which only asked to find a preferred concept and to perform preliminary evaluations. Accordingly, the subsequent design optimization are intended to be performed by the company’s staff. Originality/value The present paper shows an original design approach, opportunely tailored to the design of innovative gearboxes. It can be conveniently adapted and reused by designers involved in similar tasks. Moreover, the designed cycloidal gearbox paves the way for important innovations in the field of concrete mixers, allowing to design more robust and compact devices.

“…Restricted by the complexity and uncertainty of reasoning processes and the incompleteness of reasoning knowledge [17][18][19][20], the AI-based FBS model for function reasoning mainly deals with the conceptual design of mechanical systems in series combinations [21][22][23][24] but fails to support non-routine design problems [13,25]. To overcome the flaws ascribed to classical function-based methods and increase the FBS model's capability to generate creative design schemes, the integrated framework [26,27] to manage abstraction levels…”

Domain Reconstruction and Mutation Approach to Expand Creative Design Solution Space for Practical Mechanical Systems

Mechanical systems are fundamental means and carriers for expanding human physical strength. Their novelty is the key factor to determine the cost of manufacture and maintenance, service life, reliability, and other comprehensive performance of products. However, the function-based synthesis methods mainly focus on expanding the solution space in the function layer; each artifact only matches a subfunction individually. Consequently, the obtained physical structures to realize the overall function of design problems are bloated rather than concise. For overcoming this flaw，a computerized creative design system for solving non-routine design problems based on the domain synthesis theory in quotient space was proposed in our previous studies by introducing two bottom-up rule-based matching processes to replace the function-form direct mapping in the FBS model and using form-independent and solution-neutral fine granularity function units to describe the subfunctions. In this paper, the domain reconstruction and mutation processes are introduced to expand the solution space of creative design and increase the creativity of matching physical structures for mechanical systems further. The case study shows that domain reconstruction can effectively imitate human experts' creative design skills to realize the ingenious combination of mechanisms and expand the function-form mapping solution space to the creative solution space. Moreover, the domain mutation can obtain more simplified physical structures to realize the complex top-level functions with few constituent devices. Utilizing fewer and simpler constituent physical structures to meet the functional requirements synergistically determine that the physical structures of mechanical systems figured out by the platform have prominent market competitive advantages due to their structural simplicity and novelty.
