Engineers frequently refer to catalogues when designing products and by carefully selecting standard components, they are able to create their own unique systems. Unfortunately, these catalogues tend to serve a limited audience as they favour experienced designers. This research is aimed at developing a software framework that renders catalogue data more accessible to novice designers. The system envisaged is composed of a highly object oriented virtual design environment that allows engineers to develop their products at the conceptual level and then draw on catalogue data as they enter the embodiment and specification phase of the design process. In addition to catalogue data, this design environment must integrate other design aids, such as graphics, simulation and analysis programs. Ultimately, the virtual environment should allow novice designers to develop systems that rival those of experienced engineers using traditional catalogues.

Design Cycle

Abstract Shape modeling plays a vital role in the design process but often it is the most tedious task in the whole design cycle. In recent years the Computer Aided Design (CAD) industry has evolved through a number of advances and developments in design methodology. However, modeling in these CAD systems requires expertise and in-depth understanding of the modeling process, user interface and the CAD system itself, resulting in increased design cycle time. To overcome these problems a new methodology and a system called “Detailed Virtual Design System” (DVDS) has been developed for detailed shape modeling in a multi-modal, multi-sensory Virtual Environment (VE). This system provides an intuitive and natural way of designing using hand motions, gestures and voice commands. Due to the lack of effective collaborative design, visualization and analysis tools, designers spend a considerable amount of time and effort in the group discussion during design process. To enable multiple designers to effectively and efficiently collaborate in a design environment, framework of a collaborative virtual environment, called “Virtual Environment to Virtual Environment” (V2V), has been discussed. This framework allows same site and remote site multi-modal, multi-sensory immersive interface between designers.

Insight Into

This paper outlines continuing work on the intelligent design catalogue. The intelligent design catalogue seeks to create a virtual design environment that is linked to a catalogue of standard parts. The theoretical framework for this research draws on several engineering areas. Within manufacturing, process plans can be developed in a virtual environment independently of the machines on the shop floor just as products can be conceptually designed independently of the standard parts available. The standard parts themselves can be grouped borrowing from classification schemes of Group Technology. Object-Oriented Programming (OOP) provides an environment for the development of the software that runs the intelligent design catalogue. As the objects of OOP parallel standard components, OOP also serves as a design paradigm after which the catalogue can be modelled. . Design theory suggests frameworks for developing a (semi-) hierarchical structure for cataloguing parts and design case studies offer insight into differences between novice and expert designers.

An overview of a virtual design environment (virtual platform) developed as part of the European Commission funded VRShips-ROPAX (VRS) project is presented. The main objectives for the development of the virtual platform are described, followed by the discussion of the techniques chosen to address the objectives, and finally a description of a use-case for the platform. Whilst the focus of the VRS virtual platform was to facilitate the design of ROPAX (roll-on passengers and cargo) vessels, the components within the platform are entirely generic and may be applied to the distributed design of any type of vessel, or other complex made-to-order products.

ABSTRACTThe purpose of this paper is to outline the structure of the DLR integrated rotorcraft design process. The complexity of rotorcraft design requires the development of the tools directly by the specialists of the respective institutes, where the tools are continuously refined and published to authorised users. The integration of the tools into a suitable software framework by means of distributed computation and the harmonisation of the tools among each other are presented. This framework delivers a high level of modularity making the layout and testing of the process very flexible. This design environment covers the conceptual and preliminary design phases. Not only conventional main/tail rotor configurations can be designed, but also some other configurations with more than one main rotor. The fundamental concept behind the layout of the tools is demonstrated, especially the use of scaling and optimisation loops in connection with the different levels of fidelity and the different phases of design.

Mechanical design education focuses on teaching students with fundamental design theory and methodology. Educators systematically introduce design theories, processes, and tools to help students solve design problems. Companies and professional organizations expect that students will be equipped with basic understanding of the engineering practice, and be able to effectively perform independently and in a team environment. Senior capstone design courses, particularly with industry sponsored projects, are widely used to satisfy both education and professional needs of students. This paper presents an education system, which can further facilitate students to acquire design skills in a real-time collaborative, and practical environment. The web-based system helps student teams to: (1) specify the design process for their team projects, (2) organize and distribute tasks among different team members to simulate industry design environment, and (3) get instantaneous access to models, analysis, etc. related to their design. The developed web-based system also contains a knowledge-base that provides students with instructions to setup the design process for projects, and to perform different design tasks. A virtual design organization is created in the system, which is managed by students. In this paper different components of the web-based design education system are presented.

The Virtual Environment Operating Shell (veos) was developed at University of Washington's Human Interface Technology Laboratory as software infrastructure for the lab's research in virtual environments. veos was designed from scratch to provide a comprehensive and unified management facility to support generation of, interaction with, and maintenance of virtual environments. VEOS emphasizes rapid prototyping, heterogeneous distributed computing, and portability. We discuss the design, philosophy and implementation of veos in depth. Within the Kernel, the shared database transformations are pattern-directed, communications are asynchronous, and the programmer's interface is LISP. An entity-based metaphor extends object-oriented programming to systems-oriented programming. Entities provide first-class environments and biological programming constructs such as perceive, react, and persist. The organization, structure, and programming of entities are discussed in detail. The article concludes with a description of the applications that have contributed to the iterative refinement of the VEOS software.

This paper describes an interactive virtual environment for modeling and designing factories and shop floors. The factory building tool is developed as an open architecture in which various modules can be utilized to quickly implement factory design algorithms ranging from plant layout to factory flow analysis. Software modules and utilities have been implemented to allow easy set-up of the visual interface. In this paper, this virtual factory is used to implement cellular manufacturing (CM) system. CM has traditionally been a very complicated system to implement in practice. However successful implementation of the system has improved productivity immersely. Several issues involved in implementing CM within our virtual factory machine modeling and interface designs for defining the cells, are discussed. The mathematical clustering algorithm called Modified Boolean Method was implemented to automatically generate complex virtual environments. The virtual factory makes the process of CM-based factory design a very easy and intuitive process. Though the cell formation problem is NP-complete in 2D space, issues related to human factors and ergonomics can be better perceived in a 3D virtual environment. It also leads to further optimization with respect to maintainability and performance, and thus help get better solutions, which are not visible unless the factory is built. Our virtual factory interface also allows easy reassignment of machines and parts, subcontracting of bottleneck parts and rearranging of machines within the same design environment, making this a productive industrial tool. 3D virtual factory can also be automatically generated from the Part Machine interface called the Virtual Matrix Interface.
