“…Our second research question was: Can designers showing evidence of fixation (from either source-a provided example or their own initial example) break away from it in the same session through the use of a design ideation tool? While several idea generation tools have been shown to reduce fixation [23], design heuristics were selected for this study as an example of a design ideation tool supporting idea generation [64]. Design heuristics are empirically tested and shown to be helpful in idea generation [64,69,70,72].…”

“…Reviews of this burgeoning research area have explored how variations in cognitive processes lead to fixation, and called for further research to identify how fixation on examples limits the generation of alternatives [10,11,21,22]. Other studies have examined fixation in more varied design settings, including additive manufacturing [23], information system design [24], and "in the wild" [25].…”

Jansson and Smith (1991, "Design Fixation," Des. Stud., 12(1), pp. 3-11) demonstrated that design fixation occurs when an example solution is provided along with a design problem. After seeing an example concept-even with its flaws pointed out-new designs often share its features. In Jansson and Smith's studies, a control group saw no example and showed less fixation to the example provided only in the other group. However, another source of fixation from an initial example may arise in the control group from the designer's own first-generated concept. We conducted a large-scale experiment with beginning engineers to investigate whether design fixation occurs even without seeing a provided example. Half of the participants saw an example solution and half were given no example; instead, they generated their own initial design. Next, all students were individually brainstormed ideas for 30 min. We analyzed both groups' concepts for fixation on the first solution they saw-either the example provided or their own initial concept. The results showed that the students provided with an example concept experienced less fixation on the initial example than those in the control group, whose concepts were evaluated for similarity to their own initial concept. To consider whether fixation on initial examples (provided or self-generated) might be mitigated, we asked these students to complete a second (30 min) idea generation phase using Design Heuristics for idea inspiration. The results showed that both groups experienced less fixation during the second-generation phase. These findings suggest that fixation on first solutions occurs in individual idea generation arising from both provided examples and self-generated concepts. However, more divergent idea generation can be facilitated through the use of design tools, such as Design Heuristics, to mitigate the consequences of design fixation.

“…First, studies show signs of design fixation when additive manufacturing is a part of the process (such as prototyping), but conventional methods are ultimately used for larger production (Abdelall et al 2018b). This series of work promotes software to mitigate fixation when moving between the two methods (Abdelall et al 2018a). Designers have also shown a tendency to fixate on manufacturing constraints that have limited past designs when learning new manufacturing capabilities, a concept coined Manufacturing Fixation in Design (MFD) (Bracken Brennan et al 2021).…”

Hybrid manufacturing, a combination of additive and subtractive manufacturing capabilities in one system, has recently become a more viable production option across several industries. Although current hybrid manufacturing research covers a broad range of topics, there is a lack of focus on how this new technology impacts both the designer and the operator of hybrid systems. This paper identifies areas of literature across design theory and Industry/Operator 4.0 research efforts and presents a path for applying this research to hybrid manufacturing users. The unique relationship between operator and designer is highlighted as they learn new strategies and develop new intuitive judgements over time to become the first experienced/expert users of hybrid manufacturing. The potential impact of excessive cognitive workload due to the novel combination of processes is discussed. This paper begins a critical discussion about proper knowledge transfer to other hybrid designers and operators, as well as towards efforts of monitoring, inspecting, and automating hybrid manufacturing processes.

“…It has been shown that novice designers in particular can create design fixation, when first designing for AM and then redesigning for traditional manufacturing methods (ibid.). Another study, however, did show that manufacturability software in the concept design phase could assist designers to avoid such design fixation (Abdelall et al, 2018a). In addition to this, the concept of a feature graph has been designed to assist both novice and experienced designers in creating manufacturable designs (Ranjan et al, 2017).…”

While many argue that Additive Manufacturing (AM) opens up new possibilities in design due to its higher degree of design freedom, it is also suggested that it can increase creativity in product design. It has been further proposed that creative outcomes are limited by the imagination of the designer: designers are often asked to take full advantage of the new design potentials given by AM, yet without having the supports that are needed to increase their creativity. Current literature focuses neither on supporting creative perspectives in Design for AM (DfAM) nor on how to manage the higher degree of design freedom that can be present. As a consequence of this noticeable gap in the literature, this paper continue to explore what areas that need to be considered in creativity management, to fully support designers in utilising their creative abilities in relation to AM in design. The paper proceeds through a literature study on creativity in DfAM and presents a case study with experienced designers who are just starting to work with AM in their design practices. This paper contributes to the field with the notion of a creativity layer laid upon DfAM, visualized by three characteristics of creativity (expertise, creative thinking skills and motivation) drawn from previous research. This results in three concrete propositions of areas that need to be considered in future research on how to include a creativity management perspective in DfAM.
