Successful collaborative design requires in-depth communication between experts from different disciplines. Many design decisions are made based on a shared mental model and understanding of key features and functions before the first prototype is built. Large-Scale Immersive Computing Environments (LSICEs) provide the opportunity for teams of experts to view and interact with 3D CAD models using natural human motions to explore potential design configurations. This paper presents the results of a class exercise where student design teams used an LSICE to examine their design ideas and make decisions during the design process. The goal of this research is to gain an understanding of (1) whether the decisions made by the students are improved by full-scale visualizations of their designs in LSICEs, (2) how the use of LSICEs affect the communication of students with collaborators and clients, and (3) how the interaction methods provided in LSICEs affect the design process. The results of this research indicate that the use of LSICEs improves communication among design team members.

Design Activities

The need to understand the design process in all its complexity is motivated by an interest in the development of tools and technologies that would be capable of aiding collaborative design teams. This development effort depends upon an understanding of design activities as they occur within a real world context. Observations of design activities that are made without direct communication with the design team members may fail to capture many of the subtler aspects of the process - aspects that are best understood when described by the design team members themselves. In order to supplement observational studies, this paper presents a case study in which a dialog with members of a variety of collaborative design teams was established in order to elicit information about the nature of collaborative design. A knowledge acquisition technique, concept mapping, was used to achieve an understanding of the role of human factors specialists within the collaborative design process specific to the Air Force's system acquisition program. Results highlight various findings about the nature of design problem solving such as the way different organizational settings influence human factors input in the design process/product. The paper discusses the usefulness of concept mapping to capture in-depth design knowledge and how this type of knowledge complements other approaches to understanding design.

The complexity of engineering systems is rapidly increasing because the number of components has increased and various engineering disciplines are involved. According to this trend, large-scale engineering systems are designed by multiple design teams with many designers of various disciplines. Although the design process by the design teams is a great deal similar to the design process by an individual designer, there is an important difference between them. Designing a large-scale engineering system with design teams can cause potential conflict among the subsystems because each team may design a subsystem without considering the other team’s subsystems. In this article, a collaborative design process is proposed to design a large-scale engineering system efficiently without the conflict among the subsystems using the Independence Axiom of axiomatic design. The proposed process uses a zigzagging process between the functional domain and the physical domain, and the online electric vehicle (OLEV) is designed by the proposed process. The OLEV is an electric vehicle which uses electric power transmitted wirelessly from the power source buried in the road. The functional requirements (FRs) and constraints of the OLEV are specified to clarify the design objectives and specifications. The prototype, which is designed by the design teams based on the defined FRs, is evaluated using the proposed process. It is found that the proposed process can lead design teams to design a product more efficiently without unnecessary iterations.

AbstractFraming is a crucial skill for connecting problem and solution spaces in the creative design process, both for individuals and teams. Frames are implicit in individuals’ cognitive thinking, but the creation of shared frames plays a vital role in collaborative design. Many studies have attempted to describe the framing process, but little is still known about how to support designers in framing, specifically in teams. This paper addresses this gap, by exploring the connection between sketching and framing within interdisciplinary teams. Following a qualitative and explorative approach, we have investigated the process and outcome of five interdisciplinary teams. We identified that sketching assists in the creation and elaboration of frames. Furthermore, in tandem with discussion and reflection, sketching helps increase the chance of a frame to survive within the design process. Our findings have practical and educational implications for improving the creative design process in interdisciplinary teams.

Integral Building Design is done by multi disciplinary design teams and aims at integrating all aspects from the different disciplines involved in a design for a building such as; archtitecture, construction, building physics and building services. It involves information exchange between participants within the design process in amounts not yet known before. To support this highly complex process an Integral Building Design methods is developed based on the combination of a prescriptive approach, Methodical Design, and a descriptive approach, Reflective practice. Starting from the Methodical Design approach by van den Kroonenberg, a more reflective approach is developed. The use of Integral Design within the design process results in a transparency on the taken design steps and the design decisions. Within the design process, the extended prescriptive methodology is used as a framework for reflection on design process itself. To ensure a good information exchange between different disciplines during the conceptual phase of design a functional structuring technique can be used; Morphological Overviews (MO). Morphology provides a structure to give an overview of the consider functions and their solution alternatives. By using this method it is presumed that it helps to structure the communication between the design team members and a such forms a basis for reflection on the design results by the design team members. This method is used in the education program at the Technische Universiteit Eindhoven and was tested in workshops for students and for professionals from the Royal Institute of Dutch Architects (BNA) and the Dutch Association of Consulting Engineers (ONRI). Over 250 professionals participated in these workshops.

Design Conflicts

Due to the product complexity and time constraint, it is common to conduct a collaborative design process to consider design requirements concurrently from the product lifecycle. However, such multi-disciplinary integration process may lead to potential design conflicts which has to be further resolved as the development continues. In this research, we propose a novel analytic model by combining the concepts of Ideal Final Result (IFR) and Trends analysis in TRIZ theory to systematically find the possible design contradictions from a top-down approach. The IFR is used to represent the integration of the developing product requirements which are requested from the collaborative team members. We then apply Trends analysis to compare the current state of existing product and the IFR state of the developing product. Therefore after comparison we will transform the differences into 39 engineering parameters defined in TRIZ to acquire possible design contradictions among components. The contributions of this methodology not only derive design conflicts systematically, but also help designers jump out of their psychological inertia and perform the design process with IFR to achieve distinct innovation.

Wikis, freely editable collections of web pages, are showing potential for a flexible documentation and communication tool for collaborative design tasks. They also provide a medium that can be further transformed by properly understanding both the need for flexibility as well as support for design thinking early in the design process. The purpose of this work is to analyze the different dimensions of the wiki from a communication perspective as applicable to design. With a focus on communication in design, we will explore the advantages and disadvantages of using wikis in student engineering design teams. Our ultimate goal is to better support the design process while exploiting the potential for increasing the shared understanding among teams using a wiki. By introducing a wiki in a globally distributed product development course, students gain hands-on experience in using wikis as a design tool. Feedback from students will be collected through questionnaires and used to improve and transform the wiki as a support tool for communication during early design collaboration.

The mantra of industry today is to design products and processes using collaborative design teams. While the potential benefits of such a design philosophy are numerous and significant, many organizations find themselves falling short in the implementation. Sometimes these shortcomings are due to cultural and technical difficulties in the organization, but too frequently they are due to a lack of knowledge as to how to collaborate effectively. Described herein is an educational initiative by Syracuse and Cornell Universities to together teach collaborative design methodologies through a common two-semester, senior-level engineering design course. In the course, not only are the lectures taught to the two cohorts of students using at-a-distance technologies, but the students are teamed in cross-university teams to execute a series of 6-week design challenges, from preliminary through detailed thermal-structural design of the external skins of seconds-generation reusable launch vehicles. An Advanced Interactive Discovery Environment (AIDE), which is a computer-based infrastructure specifically designed for this course, is used to support both synchronous and asynchronous communications amongst the team members and with the faculty. Extensive surveys of the students, together with faculty observations, indicate that proper use of collaboration tools can facilitate effective geographically-dispersed design teams, making them as successful as local design teams.

The lightweight representation of three-dimensional computer-aided design (3D CAD) models has drawn much attention from researchers as its usefulness in collaborative product development is vast. Existing approaches are mostly based on feature depression or mesh-based simplification. In this article, a new approach for 3D CAD lightweight representation based on combining triangular mesh representation and boundary representation (B-rep) is proposed. The corresponding data structure as well as the conversion method from original data given in B-rep was developed. Considered as an essential application in collaborative product development, a case study on the visualization process of large-scale assembly models represented in the proposed lightweight representation was also conducted. The validation of the approach was performed via experiments with 3D CAD models in SAT format and by benchmarking with the conventional all-faceted approach with the same level of mesh resolution.

Typical Design

In this case study, we present a project of Reflex Design Collective, an experimental social equity design consultancy based in Oakland, California. Since founding Reflex Design Collective four years ago, we have reimagined the role of “designers” to transform relationships structured by oppression. To illustrate this reimagination, we present a case study of our work as ecosystem-shifters. In 2017, we facilitated a co-design innovation summit where unhoused Oakland residents led collaborative efforts to alleviate the burdens of homelessness, with city staff and housed residents serving as allies instead of experts. Our approach to design facilitation differs from a typical design thinking process by pairing our clients with those on the front-lines of social inequity in a collaborative design process. Specifically, we elevate the importance of democratized design teams, contextualized design challenges, and ongoing reflection in a design process. We highlight successes of our design facilitation approach in the Oakland homelessness summit, including outcomes and areas for improvement. We then draw higher-level key learnings from our work that are translatable to designers and managers at large. We believe our approach to equity design will provide managers and designers an alternative mindset aimed to amplify the voices of marginalized groups and stakeholders.
