Triple Helix Ideation: Comparison of Tools in Early Phase Design Processing

This paper presents a case study on design interaction and processing incorporating triple tool modalities. The methodology and processes applied are directly related to our research and exploration of new design tools, mixed reality, user-interfaces and user experiences based on a holistic framework and learning-by-doing approach in early phase design processing. We deployed three separate collaborative design-task tests based on the same problem definition. We studied the correlation between the ease of tool use, tool performance, tool satisfaction, tool expectations and experience

Framing the concept of autonomy in system design

Advancements in multiple domains have led to a focus on autonomy in engineered systems. This focus necessitates a clear definition of the term 'autonomy' and its implications for system design. To this end, we present a framework that defines autonomy mathematically as a function of independence and task complexity. A deeper understanding is established by generating design principles that can be used to influence autonomy. We illustrate these concepts on autonomy quantification for a coffee machine and on a qualitative retrospective assessment of the evolution of autonomy for the automobile

Supporting industrial equipment development through a set of design-for-maintenance guidelines

This paper presents a leaflet with design-for-maintenance guidelines. It aims at supporting developers of industrial equipment in their design-for-maintenance practices. The use of this leaflet should lead to increased attention for design-for-maintenance aspects and to improve idea generation. The way of presenting the guidelines to the user should ensure that the support will be adopted in practice. The feedback that we have received from industrial partners indicates that the support is useful in practice. A thorough evaluation study has been planned in order to confirm this
