The DMF lab has had three papers published today in the proceedings of Design 2020.
Though the conference has been delayed due to COVID-19, the proceedings are now all available via Cambridge University Press with open access. They are:
A FRAMING OF DESIGN AS PATHWAYS BETWEEN PHYSICAL, VIRTUAL AND COGNITIVE MODELS
During engineering design, designers employ three types of model: physical, virtual and cognitive. The role and contribution of each is documented in literature albeit fragmented in nature. Consequentially, a gap in understanding exists in terms of how these models and the transitions between them impact the designer and design process. This paper begins to address this through a characterisation of each model class and an appraisal of the transitional pathways including their alignment to seminal design frameworks.

DEMOCRATISING DESIGN THROUGH SURROGATE MODEL CONVOLUTIONAL NEURAL NETWORKS OF COMPUTER AIDED DESIGN REPOSITORIES
The capability to manufacture at home is continually increasing with technologies, such as 3D printing. However, the ability to design products suitable for manufacture and use remains a highly-skilled and knowledge intensive activity. This has led to ‘content creators’ providing vast repositories of manufacturable products for society, however challenges remain in the search & retrieval of models. This paper presents the surrogate model convolutional neural networks approach to search and retrieve CAD models by mapping them directly to their real-world photographed counterparts.

LOOKS LIKE BUT DOES IT FEEL LIKE? INVESTIGATING THE INFLUENCE OF MASS PROPERTIES ON USER PERCEPTIONS OF RAPID PROTOTYPES
Prototyping is a key part of the design process, with artefacts increasingly fabricated using 3D printing methods. However, these printed parts often lack internal structure and the mass properties of the artefact – mass, balance and moments of inertia – differ from the design. It is hypothesised that a stakeholder’s assessment of a design is affected by this misrepresentation. The work presented demonstrates that mass properties have a significant effect on stakeholder perception of prototypes. This is done through a study of University of Bristol students and consultation with industry.
