The Cost

As engineering products become more complicated, collaboration among multi-disciplinary design teams that are separated by location, time and across organizations is becoming an increasingly difficult task. To be effective, collaboration requires exchanging, interpreting and integrating knowledge in various locations. According to a recent study, the cost of this breakdown in knowledge in the automotive industry alone is at least $1 billion per year. There has been a significant amount of research in recent years to improve the accessibility of knowledge during design. Very little has, however, been invested in format, flow and relationships of knowledge to support the process of collaborative distributed design. Progress is particularly lagging for early stages of engineering design, conceptual design, when the need for and payoff of knowledge exchange is the greatest. This paper presents the Integrated Design Environment that is being developed at the Systems Modeling And Realization Technologies (SMART) Lab at the University of Massachusetts, Amherst. This environment facilitates knowledge flow, knowledge capture and reuse with a generalized graphical modeling environment for conceptual modeling and synthesis. The paper first provides a background in conceptual design and knowledge-based engineering followed by an architectural view of the environment and finally an example problem based on the design of a coffee maker to facilitate discussion.

Abstract Due to the incomplete representation schemes and the lack of high-level reasoning capability of current CAD/CAM systems, manufacturability assessment is performed by experienced designers and manufacturing engineers. The problems associated with automating manufacturing assessment include (1) the integration of a knowledge based environment within a design environment to provide reasoning capability, and (2) the development of flexible, modularized and responsive part models with levels of abstraction to support high-level reasoning which is required. Since modification of part geometries are frequently made during manufacturability assessment, the capability for part geometry modification is required at the level of interacting procedures. Consistency problems therefore occur between the geometric database in design environment and the part model in knowledge based environment. This paper presents a framework for an integrated design and manufacturability assessment environment which address these concerns.

The One

A new method for centrifugal and mixed-type compressors flow paths design based on a unique integrated conceptual design environment is presented in this article. At the heart of this new method is the translation of proven, integrated design environments that have been successfully used for axial turbomachinery for many years. This integrated environment is a seamless and swift processing scheme that incorporates stages aerodynamic analysis and preliminary design/sizing based on the one-dimensional method interactive spatial blade profiling, export of blade geometry to CAD and CFD tools, 3D stress and vibration analysis, and finally, flow modeling. The design process is demonstrated for a centrifugal compressor design utilizing AxSTREAM software.

Common Situation

Universities and corporates, in Europe and the United States, have come to a win-win relationship to accomplish goals that serve research and industry. However, this is not a common situation in Latin America. Knowledge exchange and the co-creation of new projects by applying academic research to solve company problems does not happen naturally.To bridge this gap, the Design School of Universidad de los Andes, together with Avianca, are exploring new formats to understand the knowledge transfer impact in an open innovation network aiming to create fluid channels between different stakeholders. The primary goal was to help Avianca to strengthen their innovation department by apply design methodologies. First, allowing design students to proposed novel solutions for the traveller experience. Then, engaging Avianca employees to learn the design process. These explorations gave the opportunity to the university to apply design research and academic findings in a professional and commercial environment.After one year of collaboration and ten prototypes tested at the airport, we can say that Avianca’s innovation mindset has evolved by implementing a user-centric perspective in the customer experience touch points, building prototypes and quickly iterate. Furthermore, this partnership helped Avianca’s employees to experience a design environment in which they were actively interacting in the innovation process.

Abstract This paper presents an advisory conceptual design tool for mechanical transmission systems. Space consideration was taken into account during the design process. A prototype function tree was built in the form of knowledge-based system to transfer a designer’s idea into a set of mechanical components. An advisory expert system was also developed to help a designer in decision making. As an example, a packaging machine is designed using the developed system.
