“…Therefore, Nelson et al (2009) and Johnson et al (2016) propose refinements to the variety and novelty metrics, respectively. Furthermore, Fiorineschi et al (2020a) demonstrate that missing attributes in the definitions of designs (e.g. certain designs not addressing certain functions) could lead to variations in the scores when implementing Shah et al's novelty metrics.…”

Purpose The COVID-19 pandemic has resulted in numerous innovative engineering design solutions, several of which leverage the rapid prototyping and manufacturing capabilities of additive manufacturing. This paper aims to study a subset of these solutions for their utilization of design for AM (DfAM) techniques and investigate the effects of DfAM utilization on the creativity and manufacturing efficiency of these solutions. Design/methodology/approach This study compiled 26 COVID-19-related solutions designed for AM spanning three categories: (1) face shields (N = 6), (2) face masks (N = 12) and (3) hands-free door openers (N = 8). These solutions were assessed for (1) DfAM utilization, (2) manufacturing efficiency and (3) creativity. The relationships between these assessments were then computed using generalized linear models to investigate the influence of DfAM utilization on manufacturing efficiency and creativity. Findings It is observed that (1) unique and original designs scored lower in their AM suitability, (2) solutions with higher complexity scored higher on usefulness and overall creativity and (3) solutions with higher complexity had higher build cost, build time and material usage. These findings highlight the need to account for both opportunistic and restrictive DfAM when evaluating solutions designed for AM. Balancing the two DfAM perspectives can support the development of solutions that are creative and consume fewer build resources. Originality/value DfAM evaluation tools primarily focus on AM limitations to help designers avoid build failures. This paper proposes the need to assess designs for both, their opportunistic and restrictive DfAM utilization to appropriately assess the manufacturing efficiency of designs and to realize the creative potential of adopting AM.

“…This kind of experiment could be prohibitive and too much onerous to be performed. However, a hint to overcome the problem can be found in the recent work of Fiorineschi, Frillici, and Rotini (2020a) , where a very high number of 'virtual sets of ideas' has been exploited to evaluate the differences between M SNM and M SNM . The same experiment can be repeated by considering M SNM in place of M SNM .…”

The concept of novelty in terms of 'uncommonness' of ideas is one of the most considered in design studies. Accordingly, the metric developed by Shah, Vargas-Hernandez and Smith in 2003 (SNM) is still one of the most largely used. Nonetheless, it presents non-negligible and still unsolved problems when applied to realistic sets of ideas implementing heterogeneous numbers of attributes. This paper aims at identifying the roots of these problems and at proposing a refined assessment approach, capable to extend the applicability of SNM to any set of ideas. Generic boundary cases have been used to demonstrate the validity of the proposal, while its potential impact on the final novelty values has been estimated by assessing a real set of 100 ideas.

“…More precisely, it is possible to investigate if and to what extent the proposed SO approach can stimulate designers to generate ideas 'new in relation to their personal knowledge', i.e., the so-called 'psychological creativity' [29]. In this case, the a posteriori novelty metric of Shah can be used by considering the recent observations and improvements [30][31][32].…”

The System Operator (SO), also known as Nine Boxes or Multiscreen, is classically used for analysing the undesired situation according to different perspectives. However, its logic can be suitably exploited also for other kinds of tasks. In such a context, this paper shows an alternative application of the SO. In particular, the new proposed SO approach allows us to formulate alternative problems, i.e., different from the central one, although referring to the same problem-solving task. By applying the proposed procedure to a real case study, this paper shows that the tool can be used for problem analysis and formulation purposes, aimed at better clarifying the problem-solving task. The case study concerns a preliminary set of experiments performed to evaluate the possibility of obtaining angular shapes by bending tiles made by a specific compostable composite material. The suggestions obtained using the proposed SO approach allowed us to find potentially valid solutions, thus paving the way for further validation tests. In particular, tests are still needed to validate the actual potentialities of the proposed SO. Additionally, further and more comprehensive tests are required to validate the solutions inferred in this study concerning the compostable tiles.
