Abstract Ongoing work within the engineering design research community seeks to develop automated design methods and tools that enhance the natural capabilities of designers in developing highly innovative concepts. Central to this vision is the ability to first obtain a deep understanding of the underlying behavior and process dynamics that predict successful performance in early-stage concept generation. The objective of this research is to better understand the predictive factors that lead to improved performance during concept generation. In particular, this work focuses on the impact of idea fluency and timing of early-stage design concepts, and their effect on overall measures of ideation session success. To accomplish this, we leverage an existing large-scale dataset containing hundreds of early-stage design concepts; each concept contains detailed ratings regarding its overall feasibility, usefulness, and novelty, as well as the completion time of each idea. Surprisingly, results indicate that there is no effect of idea fluency or timing on the quality of the output when using a holistic evaluation mechanism, such as the innovation measure, instead of a single measure such as novelty. Thus, exceptional concepts can be achieved by all generator segments independent of idea fluency. Furthermore, in early-stage concept generation sessions, highest-rated concepts have an equal probability of occurring early and late in a session. Taken together, these findings can be used to improve performance in ideation by effectively determining when and which types of design interventions future design tools might suggest.

Sketching and prototyping of design concepts have long been valued as tools to support productive early stage design. This study investigates previous findings about the interplay between the use and timing of use of such design tools. This study evaluates such tools in the context of team design projects. General trends and statistically significant results about “sketchstorming” and prototyping suggest that, in certain constrained contexts, the focus should be on the quality of information rather than on the quantity of information generated, and that prototyping should begin as soon as possible during the design process. Ramifications of these findings are discussed in the context of educating future designers on the efficient use of design tools.

Conceptual sketches of design alternatives are often employed as a tool for eliciting feedback from design stakeholders, including potential end-users. However, such sketches can vary widely in their level of finish and style, thus potentially affecting how users respond to a concept. This paper presents a study of user responses to three objects drawn in styles ranging from rough hand sketches to CAD drawings. This study also considers the amount of design time required to create the sketches. Results show that respondents generally ranked realistic, “clean” hand sketches the highest over other types of sketches, particularly “rough” sketches. These types of sketches took longer than other types of hand sketches to create, but were still much faster than CAD renderings. Results also suggest that the complexity and familiarity of an object can influence how users respond to a sketch.

The Impact

Building Information Modelling (BIM) and its associated technologies have proved to be one of the most promising developments in the Architectural, Engineering and Construction (AEC) industry. Over the past few decades, the AEC sector has been restricted in its communication of design as a result of single interface methods based on 2D and 3D visualization of information. Thus, most issues with respect to construction are identified fairly late, resulting in costly changes. With the introduction of BIM, many other approaches to data visualization can be leveraged including Mixed Reality (MR) applications for the virtual representation of spaces and objects beyond 3D. MR offers a revolution in the virtual representation of objects and space through context awareness as well as the incorporation of information beyond 3D offering countless opportunities for more effective design visualization and coordination. Despite the capability of MR, however, few examples exist of its application to design coordination in the AEC. In addressing this gap this study proposes a novel methodology for the application of MR in design coordination as well as investigates the impact of introducing MR into BIM workflow with a focus on the identification and avoidance of clashes. A prototypical model of the MR design coordination is presented and discussed. Findings indicate that MR improves design productivity and quality but also highlights potential infrastructure issues inhibiting the mainstreaming of MR for design practice.

And Function

In this paper, we explore the possibility of reconciling and integrating practical affordance- and function-based design representations. We present a classic function-based design method and representation and argue for the benefits of augmenting it with affordance-based approaches. Building on existing function concept ontologies, we present an integrated approach to developing early-stage design representations. This approach combines the use of affordance and function representations to capture user needs across a device's life cycle. We demonstrate how affordances add rigor and expressiveness to the early stages of traditional design processes, and how traditional function-based tools provide affordance-based design (ABD) with structured methods for concept generation. The integrated approach is illustrated with an example, in which a use case is explicitly decomposed to demonstrate the structure of relationships between users, goals, actions, artifacts, functions, and affordances.

The Impact

The aim of this paper is to demonstrate by “facts and figures” the perceived influence of rule changes, including but not limiting to the safety for special purpose ships (SPS) codes and marine regulatory changes since 2000, in the design of different offshore vessel. It is stated by many that practical design of offshore vessels, as one of the major groups of special purpose work vessels, has been significantly influenced by new rules introduced. For example, SPS code developments over the last years, have created challenges for designers besides endless argumentations to envelope proper sample of vessels for similar vessel based designs. The same problems are observed within performance benchmarking of samples and fleets of vessels over time series. However, enabling designers and decision makers in the early stage design phase to understand the impact of such codes and regulations on vessels’ price, performances, capacities and capabilities, is a significant and important issue, which has not been studied comprehensively during the last years. This influence study is based on two major design perspectives of ‘design for Efficiency’ and ‘design vessel for Effectiveness.

Gathering user feedback on provisional design concepts early in the design process has the potential to reduce time-to-market and create more satisfying products. Among the parameters that shape user response to a product, this paper investigates how design experts use sketches, physical prototypes, and computer-aided design (CAD) to generate and represent ideas, as well as how these tools are linked to design attributes and multiple measures of design quality. Eighteen expert designers individually addressed a 2 hr design task using only sketches, foam prototypes, or CAD. It was found that prototyped designs were generated more quickly than those created using sketches or CAD. Analysis of 406 crowdsourced responses to the resulting designs showed that those created as prototypes were perceived as more novel, more aesthetically pleasing, and more comfortable to use. It was also found that designs perceived as more novel tended to fare poorly on all other measured qualities.

To support the development of TheDesignExchange — a portal to a comprehensive set of design methods applicable to a range of disciplines — we hosted a series of workshops with design students, educators and practitioners. In this paper, we summarize insights gained from the three practitioner workshops associated with early stage design methods used to: Research, Analyze and Communicate. We contrast the practitioner feedback with insights from previous workshops with design students and educators. We also discuss implications for enhancing professional skills and industry practice into design education.

AbstractPhysical prototyping during early stage design typically represents an iterative process. Commonly, a single prototype will be used throughout the process, with its form being modified as the design evolves. If the form of the prototype is not captured as each iteration occurs understanding how specific design changes impact upon the satisfaction of requirements is challenging, particularly retrospectively.In this paper two different systems for digitising physical artefacts, structured light scanning (SLS) and photogrammetry (PG), are investigated as means for capturing iterations of physical prototypes. First, a series of test artefacts are presented and procedures for operating each system are developed. Next, artefacts are digitised using both SLS and PG and resulting models are compared against a master model of each artefact. Results indicate that both systems are able to reconstruct the majority of each artefact's geometry within 0.1mm of the master, however, overall SLS demonstrated superior performance, both in terms of completion time and model quality. Additionally, the quality of PG models was far more influenced by the effort and expertise of the user compared to SLS.
