    Distributed product design

    Distribution of design tasks is a measure to accelerate the product design process. In a distributed design environment based on broadband communication network it is feasable to split the design task into functional and shape related subtasks. Under the supervision of a project management system the design tasks can be worked out in parallel and independently. The product model of the design system can include information about design space, design constraints and connections to other design subtasks.

    The sequential execution of the product development stages is still the mostly used method in industry nowadays. A very short lead-time in product life cycle is one necessity for a good and safe position in the market. Very often the time-to-market decides about the success of a product. Therefore it is not only sufficient to shorten single stages of the product development process. It is rather necessary to let those stages run in parallel. The result is an overlapping of product development stages which is the kernel spirit of Simultaneous Engineering (SE). The intradepartmental research center TUB-KOM is an installation in the TU Berlin where research and development for broadband communication technique is concentrated and coordinated out of different areas in the university.

    Virtual spaces to support feature-based computer aided design
    ( 1994)

    Increasingly high demands placed on the product development process with respect to the shortening of development and job throughput times, the lowering of development costs and an improvement in product quality have raised the requirement for unbroken continuity in the information-technological linkage of the associated tasks into process chains. Beyond the geometrical description of the component shape, the exchange of semantic information for use in all phases of product development must be supported. To meet these requirements features can be used as semantically endowed objects that accompany the product development process from customer request throgh the product release. The essential requierement here is the ability to define and process the features in a task- and product-specific fashion and to adapt them flexibly to the chaning constraints of product development. Parametrical models generated with features support the automation of associated design, configuration and planni ng processes.

    New hardware and software tools based on wide-band communication techniques are opening innovative ways of distributed product development, in connection with multimedial systems and techniques of cooperation. At the example of a system implemented as a prototype it presents the basic possibilities for improvement and provides an outlook on the future potentials which are connected to that technique

    Eine Sprache für die featureorientierte Beschreibung und Verarbeitung von Produktgestaltungsinformationen

    For efficient computer aided design it is nessessary to provide an object oriented modelling environment. This requirement is fulfilled by using the feature approach. Features are intelligent design objects, including their shape and their functional and technological behaviour. A language has been developed to describe features in an object oriented manner. This language allows the description of all feature related information, including design rules and functional constraints. New features are generated in a graphical interactive environment. The resulting textual feature description is then interpreted during runtime, taking into account the current design state. The described feature modeller is part of an integrated system for product and process modelling.

    Feature modelling systems serve for the integrated processing of geometric, technological and functional information during design. They enable the designer to work with design elements he is accustomed to. Information contained in the feature model can be accessed and processed by other phases involved in the product development. This article describes a feature modelling system and the resulting design environment.

    PDGL - A language for efficient feature based product gestaltung

    For high level and efficient computer aided design it is necessary to provide the possibility of object oriented modeling. A language has been developed to describe features in an object oriented manner including their technological semantics. The resulting generic feature templates are interpreted by the modeling system during runtime. Therefore the specific feature takes the actual design into account. By computing derivable parameters automatically, integrating related standard tables and by regarding design rules, features behave according to their associated semantics. During product gestaltung with features, the user works in his semantical environment and not only with geometric primitives. The concept for the feature design language as well as some examples demonstrating the advantages of the concept are presented.
