“…This characteristic allows the generation of a multitude of possible product configurations and through this the realization of optimization cycles which can lead to product configuration which represent an optimum solution in a multi-dimensional solution space. This is especially advantageous for systems with many configuration possibilities such as wire harnesses and pipe systems such as exhaust systems (Vogel and Rudolph 2016). The third notable advantage is the possibility to include multiple physical domains, e. g. it is possible to address simultaneously the mass and moment balance and thermal validation of a satellite (Vogel and Rudolph 2018).…”

Graph-based design languages offer a promising approach to address several major issues in engineering, e. g. the laborious manual transfer between CAD and CAE. Such languages generate a digital meta- or system model storing all relevant information about a design and feed this into any relevant CAE tool as needed to simulate and test the impact of any design variation on the resulting product performance. As this can be automated in digital compilers to perform systematic design variation for an almost infinite amount of parameters, such graph-based languages are a powerful means to generate viable design alternatives and thus permit fast evaluations.To leverage the full potential of graph-based design languages, possibilities are presented to expand their applicability into the domain of product functions. This possibilities allow to cohesively link integrative function modelling to product structures. This intends to close the gap between the early, abstract stages and the systematic, concrete design generation and validation with relevant CAE tools. In this paper, the IFM Framework was selected as integrated function model to be linked with the graph- based design languages.

“…The integration of the components is validated for the defined orbits in terms of thermal loads arising from the incoming sun light as well as heat sources from components and systems ( figure 4 bottom left). Finally, figure 5 shows results of a design language for the automated functional optimization of SCR (selective catalytic reaction) exhaust aftertreatment systems, that reduce the emissions of internal combustion engines [10,13]. At the beginning a combustion engine is given in terms of mass flow and exhaust temperature as well as emissions and emission target.…”

“…The scope of design languages has been prototypically extended up to downstream stages of the life-cycle by generating and designing the digital factory for a product in addition to the product itself [12]. Additional work has been done in the implantation of algorithms to automate engineering tasks as routing of cables and wires [8] and the automated creation of pipework in given installation spaces [13]. These intelligent wiring and piping algorithms become necessary as graphbased design languages fully automate the design process and therefore need to be able to create an intelligent integration and interaction of system components in given installation spaces for different product architectures.…”

Graph-based design languages in UML (Unified Modeling Language) are presented as a method to encode and automate the complete design process and the final optimization of the product or complex system. A design language consists of a vocabulary (i.e. the digital building blocks) and a set of rules (i.e. the digital composition knowledge) along with an executable sequence of the rules (i.e. the digital encoding of the design process). The rule-based mechanism instantiates a central and consistent global product data structure (the so-called design graph). Upon the generation of the abstract central model, the domain-specific engineering models are automatically generated, remotely executed and their results are fed-back into the central design model for subsequent design decisions or optimizations. The design languages are manually modeled and automatically executed in a so-called design compiler. Up to now, a variety of product designs in the areas of aerospace (satellites, aircraft), automotive (space frame structures, automotive cockpits), machinery (robots, digital factory) and consumer products (coffeemakers) have been successfully accelerated and automated using graph-based design languages. Different design strategies and mechanisms have been identified and applied in the automation of the design processes. Approaches ranging from the automated and declarative processing of constraints, through fractal nested design patterns, to mathematical dimension-based derivation of the sequence of design actions are used. The existing knowledge for a design determines the global design strategy (i.e. top-down vs. bottom-up). Similarity-mechanics in the form of dimensionless invariants are used for evaluation to downsize the solution for an overall complexity reduction. Design patterns, design paradigms (i.e. form follows function, or function follows form) and design strategies (divide and conquer) from information science are heavily used to structure, manage and handle complexity.

“…Meanwhile, the simplified routes represented by discrete points or voxels are far from the practical pipe models, making it hard to consider some engineering constraints such as manufacturability and the end pose requirement during the routing process. Vogel and Rudolph (2016) proposed a pipe route generation method using standardized pipe bends, which reduces the manufacturing costs for general engineering applications. Nevertheless, the fixed bend angles and radii induced extra constraints on the routing design process.…”

Purpose This paper aims to propose an optimization method to automatically adjust the spatial route of multibend pipes to meet the assembly demands in constrained space. Design/methodology/approach The compact geometric parameters that uniquely determine the pipe route are analyzed. Besides, the relationship between these parameters and the end pose is revealed based on the exponential product formula. Mathematical representations for the engineering constraints, including the end pose restriction, collision interference, manufacture ability and geometric limitations, are further established. On this basis, the adjustment of the spatial route is formulated as a multiconstraint optimization problem. A modified particle swarm optimization method based on the combination of gradient projection and swarm intelligence is designed to find the near-optimal pipe that meets the required assembly demands. Findings The experimental results show that the proposed method can effectively find the feasible pipe route that satisfies the engineering constraints and the end pose requirement is highly guaranteed. Originality/value The proposed method can automate the geometric adjustment of multi-bend pipes to meet the actual assembly demands, which significantly reduces manual efforts and guarantees high accuracy. The results demonstrate the possibility of further applications in the pipe assembly or design process, especially in ships, aerospace products or pressure vessels.
