|Abstract: ||Purpose – The purpose of this paper is to report on a geometrical integration methodology that can be
used to organise some types of these systems. Most multipath delivery systems, such as Building
Services (BSs), are arbitrarily distributed with no known solution to reduce the complexity in the way
channels are arranged.
Design/methodology/approach – Integration for optimal functionality through reduction of
geometrical complexity is achieved by understanding the elements of complexity within current
practices; identifying commonalities between the various components which can be used for
integration; performing an axiomatic design to resolve design complications; adopting theory of
inventive problem-solving for methodology and process development towards optimal functionality;
and 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 (CAD) 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. It is applied
to bring together BSs into a single trunking system at minimal, yet appropriate, proximal distances, and
it 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/value – 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
