Design And Manufacturing

Abstract In this paper, we present a new paradigm where design and manufacturing processes can be integrated. Engineers can do what-if analysis of a particular design choice before they continue with the design process, and select a design process that meets constraints such as cost, manufacturing setting and machine shop resources. These constraints in turn enforce the designer to choose the ‘correct’ parameters and processes in earlier stages of design. Even with an incomplete set of design data, problems in manufacturing can be forecasted to the engineers in product development. The crux of the new paradigm is a process grammar, which provides the abilities to represent, abstract, manipulate and execute design and manufacturing processes. The grammar also provides a theoretical foundation for an execution environment to carry out the iterative nature of the engineering process. This approach to the integration of engineering design processes can also be applied to coordinate concurrent engineering activities in a distributed environment. We have developed a web-based prototype of the framework called Manufacturing Integration and Design Automation System (MIDAS). The represented design and manufacturing processes can be executed in a distributed environment through a process controller. Communication among engineers is made through a collaborative design browser with various visualization tools. MIDAS conforms to the CORBA standard, and uses JAVA to create a platform independent environment on the Web.

In this paper, we present an engineering framework called Manufacturing Integration and Design Automation System (MIDAS). The core of MIDAS is a process grammar, which provides the theoretical foundation to represent, manipulate and execute design and manufacturing processes. The important properties offered by MIDAS, which are especially useful for integrating design and manufacturing, are generativity and abstraction. Given a set of rules and objects, it generates feasible alternative processes that can be represented at varying levels of abstraction. Generativity and abstraction allow users of MIDAS to explore alternative processes while coordinating and integrating iterative engineering activities concurrently in a distributed environment. When design and manufacturing processes are integrated within the framework of MIDAS, it helps engineers to navigate through the process alternatives and to foresee the effects of particular design choices in subsequent stages of design and manufacturing, even with an incomplete set of design data. Using a shared representation of design and manufacturing processes, MIDAS facilitates communication among engineers through a collaborative browser and various visualization tools.

Early Stages

Stir was a crowd-voted grants platform aimed at supporting creative youth in the early stages of an entrepreneurial journey. Developed through an in-depth, collaborative design process, between 2015 and 2018 it received close to two hundred projects and distributed over fifty grants to emerging creatives and became one of the most impactful programs aimed at increasing entrepreneurial activity in Canberra, Australia. The following case study will provide an overview of the methodology and process used by the design team in conceiving and developing this platform, highlighting how the community’s interests and competencies were embedded in the project itself. The case provides insights for people leading collaborative design processes, with specific emphasis on some of the characteristics on programs targeting creative youth

Abstract We introduce a method to help protect against and mitigate possible consequences of major regional and global events that can disrupt a system design and manufacturing process. The method is intended to be used during the conceptual phase of system design when functional models have been developed and component solutions are being chosen. Disruptive events such as plane crashes killing many engineers from one company traveling together, disease outbreaks killing or temporarily disabling many people associated with one industrial sector who travel to the same conference regularly, geopolitical events that impose tariffs or complete cessation of trade with a country that supplies a critical component, and many other similar physical and virtual events can significantly delay or disrupt a system design process. By comparing alternative embodiment, component, and low-level functional solutions, solutions can be identified that better pass the bus factor where no one disruptive event will cause a major delay or disruption to a system design and manufacturing process. We present a simplified case study of a renewable energy generation and storage system intended for residential use to demonstrate the method. While some challenges to immediate adoption by practitioners exist, we believe the method has the potential to significantly improve system design processes so that systems are designed, manufactured, and delivered on schedule and on budget from the perspective of significant disruptive events to design and manufacturing.

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.
