“…Setting the scene for consideration of the integration solution being developed in this research as a design feature into CAD, through adoption of the logic used by Noort et al (2002), who defined form features as regions of the part that have some functional meaning. The form features contain class-specific design information that is captured by means of feature elements and feature constraints.…”

Purpose: Most multipath delivery systems, such as Building-Services (BSs) are arbitrary distributed with no known solution to reduce the complexity in the way channels are arranged. This paper reports on a geometrical integration methodology that can be used to organise some types of these systems.Methodology: Integration for optimal functionality through reduction of geometrical complexity is achieved by: (i) understanding the elements of complexity within current practices; (ii) identifying commonalities between the various components which can be used for integration; (iii) performing an axiomatic design to resolve design complications; (iv) adopting theory of inventive problem solving for methodology and process development toward optimal functionality (v) generating a mathematical solution to inform digital modelling of optimal design.The study takes into account thermophysical and electromagnetic interactions between utilities; and uses novel mathematical manipulations based on designing a manifold of spherical and cylindrical geometries joined using Bezier surfaces.Findings: Once a solution was reached Computer Aided Design iterations were undertaken for channelling six BSs into a single unit. The outcome was concentric cylindrical-spherical shells superimposed with spacings of typically few millimetres to deliver/distribute the utilities. Applied to bring together BSs into a single trunking system at minimal, yet appropriate, proximal distances and allows distribution of any number of services in any direction. Physical prototypes were produced and initial testing of their performance (reported elsewhere) has been encouraging. Originality:A design methodology for integrating arbitrary distributed paths/conduits. The approach could be incorporated into CAD tools as a design feature to facilitate integration of multipath delivery systems.

“…For example, integrations between design systems and reverse engineering (Varady et al 1997;Benko et al 2001), rapid prototyping (Starly et al 2005), coordinate measurement (Kramer et al 2001), mesh generation (Rezayat 1996), virtual reality (Ma et al 2004b), process planning (Fuh and Chang 1996), and assembly systems (Noort et al 2002) have been widely studied. In these publications, the application integration is based on geometric neutral data formats, such as the Initial Graphics Exchange Specification (IGES) or the STandard for the Exchange of Product model data (STEP) (ISO 2000).…”

With widely used concurrent and collaborative engineering technologies, the validity and consistency of product information become important. In order to establish the state of the art, this paper reviews emerging concurrent and collaborative engineering approaches and emphasizes on the integration of different application systems across product life cycle management (PLM) stages. It is revealed that checking product information validity is difficult for the current computer-aided systems because engineering intent is at best partially represented in product models. It is also not easy to maintain the consistency among related product models because information associations are not established. The purpose of this review is to identify and analyze research issues with respect to information integration and sharing for future concurrent and collaborative engineering. A new paradigm of research from the angle of feature unification and association for product modeling and manufacturing is subsequently proposed.Keywords Concurrent and collaborative engineering · Feature-based design and manufacturing · Product life cycle modeling · Information validity and consistency
