“…Graph grammars have been used for the design of a coffee grinder, which covers the design process starting with the initial definition of a system boundary to the final design (Kurtoglu et al , 2010). Other research focuses on the design of sheet metal parts (Patel and Campbell, 2010), fluid channels (Hooshmand and Campbell, 2014), or trusses (Hooshmand and Campbell, 2016). Further examples include the case where graph grammars have been used in an automated design process to optimize the design at the conceptual stage for tank suspension systems (Li and Zhao, 2015).…”

In engineering and architecture, different approaches have been developed that share the use of graph transformation to automate design processes or to search for design solutions by means of computational design synthesis. In order to give an overview of these approaches, we provide a review of articles published in the last decade. Forty-eight articles were reviewed to determine similarities and differences of these approaches. Research fields in method development for the representation of design problems and the processing of graph transformations, as well as the application of graph transformations in engineering, architecture, and shape grammars were identified. Different approaches for the documentation of the vocabulary and the rules were examined. Finally, different approaches for rule applications were analyzed. Based on found limitations, future research directions are suggested.

“…Compared with the layout graph grammar, our approach offers an easier approach to layout design, since attribute transfer functions are expressed intuitively as layout constraints. Compared with the work of Hooshmand and Campbell that focuses on the generation and optimization of three‐dimensional models, our work focuses on specifying and adjusting the spatial layout of VPLs. Our approach and that of Hooshmand and Campbell suit for different application scenarios.…”

“…Compared with the work of Hooshmand and Campbell that focuses on the generation and optimization of three‐dimensional models, our work focuses on specifying and adjusting the spatial layout of VPLs. Our approach and that of Hooshmand and Campbell suit for different application scenarios. In comparison with the CG algorithm, our approach embeds predefined layout constraints into productions rather than defining layout attributes for the parse tree.…”

“…However, the method lacks the ability of handling global layout problem such as symmetries . Hooshmand and Campbell proposed a layout approach for fluid channels, which uses graph grammars to generate the topologies of fluid channels. Using a set of design synthesis methods, the method shows high capabilities in solving complex large‐scale three‐dimensional problems.…”

A graph grammar‐based approach for graph layout

et al. 2018

View full text Add to dashboard Cite

Summary As a two‐dimensional formal tool, graph grammars are capable of handling the layout problems of visual programming languages. Based on an edge‐based graph grammar (EGG), this paper proposes a novel layout approach that uses the unique features of EGG and overcomes the weakness of existing layout approaches. In order to make the approach rigorous yet concise, the graph grammar mechanisms with layout constraints and quantitative analysis techniques are combined together as an integrity. First, the basic notions of EGG are briefly introduced; second, the layout approach is presented that consists of two phases, ie, bottom‐up parsing and top‐down derivation. Finally, a case study is given by taking the standard flowchart as an example to demonstrate the working process of the proposed approach.

“…These include automotive applications (Orsborn et al 2006;, some with focus on vehicle face details (McCormack et al 2004) and vehicle side profiles (Pugliese & Cagan 2002;Yannou, Dihlmann & Awedikian 2008;Bluntzer, Ostrosi & Sagot 2014). Such shape grammar techniques are applicable to generation of 3D design representations, for example, with fluid channel layouts (Hooshmand & Campbell 2014).…”

Balancing design freedom and brand recognition in the evolution of automotive brand styling

et al. 2016

View full text Add to dashboard Cite

Designers faced with the task of developing a new product model of a brand must balance several considerations. The design must be novel and express attributes important to the customers, while also recognizable as a representative of the brand. This balancing is left to the intuition of the designers, who must anticipate how customers will perceive the new design. Oftentimes, the design freedom used to meet a product attribute can compromise the recognition of the product as a member of the brand. In this paper, an experiment is conducted for measuring changes in ten styling attributes common to both design freedom and brand recognition for automotive designs from four brands, Audi, BMW, Cadillac, and Lexus, using customer responses to two- and three-dimensional vehicle designs created and presented interactively through a crowdsourced web application. Results show that while brand recognition is highly dependent on the manufacturer, two brands have strong negative relationship between design freedom and brand recognition, suggesting that these two manufacturers face a significant challenge when evolving their respective brand styling. This study is a first effort toward quantifying and predicting tradeoffs between design freedom and brand recognition, contributing to existing efforts that augment human intuition during strategic design decisions.
