The Impact

AbstractAssessing the impact of design automation on design practice prior to its implementation is difficult and subject to uncertainties. One reason for this is the designers' lack of knowledge about design automation. In this work, an industrial case study focusing on conceptual design of hydraulic circuits is conducted to assess the impact of the designers' knowledge on design automation potential estimation. In particular, the impact of demonstrating a prototypical implementation of a design automation application is investigated as a means to enhance the designers' knowledge about design automation. In this respect, a given set of metrics is rated twice to enable a comparative study: prior to and after introducing the design automation prototype. The yielded results show that the knowledge impacts the rating and supports reliability of potential estimation. Further, it is shown that designers acknowledge design automation potential for the early stages of design given sufficient knowledge about design automation. Yet, the results also indicate that careful attention needs to be put on the aspects covered by the prototype in order to avoid biasing participants.

This paper presents an application of symmetry and connectivity to select kinematic structures of parallel manipulators. One kinematic chain can originate several mechanisms and each mechanism can originate several parallel manipulators and, in early stages of conceptual design, it is difficult to decide what is the most promising one. Hunt [1] introduced the concept of connectivity and, since then, the connectivity has been used as an important parameter to select the most appropriated parallel manipulators to develop determined task. However, it is difficult to analyze non isomorphic parallel manipulators from the connectivity matrix. In this sense, in this paper, we apply symmetry to reduce the set of parallel manipulators to a manageable few with the desired connectivity. As a result, all promising parallel manipulators originating from a kinematic chain can be analyzed without isomorphisms.

In this paper an attempt has been made to identify certain useful parts that will assist to consider reliability during conceptual design phase. The aim is to provide some thoughts and a toolkit for addressing reliability during the early stages of design, influencing design decisions and product reliability, and reducing the relying on the reliability prediction and expensive experiments in later design stage. Therefore high reliability can be cost-effectively achieved.

Design Ideas

Conceptual design is the most creative part of architectural activity. In the professional work of architects, conceptual design is given great importance. Various architectural and design forums, exhibitions, competitions are dedicated to him. In Soviet times, an interesting example of the formation of conceptual solutions is the work of Alexander Brodsky and Ilya Utkin (who signed their works as a tandem of "Brutus"). We have other solutions of interesting concepts - the object of the competition "The World of El Lysytsky" - the Globe Theater in Novosibirsk. Here the authors start from the main idea - that the cube is the main form that characterizes the spirit and style of the Russian avant-garde of the twentieth century. Conceptual design ideas are implemented in the construction of unusual hotels, atypical urban environment, non-traditional building materials. All this allows you to think about life according to other rules. Than those prescribed in building codes. The world around us is more interesting and diverse, so we can, in part, paint it in bright colors.

Design Freedom

Our primary focus in this paper is on open engineering systems. Developing ranged sets (as opposed to point sets) of top-level design specifications is a means to enhance openness and system flexibility by increasing design knowledge while maintaining design freedom. Consequently, our secondary focus in this paper is on metrics for assessing the design freedom and information certainty associated with a ranged set of top-level design specifications. As a demonstration, these metrics are applied to an example problem, namely, the conceptual design of a family of aircraft. Our emphasis in this paper is on introducing open engineering systems and metrics for design freedom and information certainty, and not on the example, per se.

Early Stages

The early stages of product development are arguably the most important in the design of successful products. This paper describes different approaches to the conceptual design phase of product development, how they are taught to undergraduate engineering students, and how they are practiced in industry both in Germany and in the United States. The authors note that teaching the early stages of product development to future engineers at German Universities is more focused on methodology and processes. In the United States teaching design is more about being creative and overcoming individual constraints in order to find good and unconventional concepts. To understand how the conceptual phase is implemented in industry, the authors interviewed 16 companies in Germany and the United States. A thematic analysis was performed on the responses. In German industry, the authors observe uncertainty about how to apply process management in the very early stage of product development where different concepts are developed and evaluated. In U.S. industry most companies do not claim to follow a process during the early stage of concept development. Observing the differences between what is taught to engineering students in school and what is practiced in industry some conclusions recommendations are drawn. The observations demonstrate a weakness in process reliability during the early stage of product development both, in German and U.S. industry that should motivate academia to adapt its pedagogy in order to enable future engineers to create successful concepts.

Indonesia is known as a country rich in types of building materials and technologies inherited from generation to generation. Along with the passage oftime appears the computer as a human tools. However during the materialsprocessing this computational approach is still separated. Computers are still usedas tools for drawing and not used as design tools in the design thinking process.Computational design has an ability to integrating the design focus from thematerial side, structure, and formation associated with digital fabrication. Thispaper focuses to divide concepts of tectonics as general and relate them to theunderstanding of digital perception. This paper also presents the results of a studythat has involved digital perception in the study of planar materials and wafflestructure systems from the early stages to the model of construction. Plywood isthe only material used, made with milling machines and built by students. Thisprocess introduces students to different experience of the design process.Computational design makes possibilities to integrating the design focus from thematerial side, structure, and formation associated with digital fabrication.

Construction materials manufactured with composite cement binders are characterized by shrinking deformation in the course of their hardening. The total deformation consists of three shrinkage types: contractional, humid and carbonizing. The analysis of crack propagation in building materials is important because its changes result in the reduction in the service life of building structures. Humid and carbonizing shrinkages are determined for various construction materials. It is found that contractional shrinkage of construction materials may significantly ex-ceed shrinking deformations which occur during material drying. Possible ways to decrease con-tractional shrinkage are considered. It is shown that one of the more effective ways to reduce shrinking deformations is forced carbonization of building mixes, especially at early stages of hardening.

PurposeThe integration and automation of the whole design and implementation process have become a pivotal factor in construction projects. Problems of process integration, particularly at the conceptual design stage, often manifest through a number of significant areas, from design representation, cognition and translation to process fragmentation and loss of design integrity. Whilst building information modelling (BIM) applications can be used to support design automation, particularly through the modelling, amendment and management stages, they do not explicitly provide whole design integration. This is a significant challenge. However, advances in generative design now offer significant potential for enhancing the design experience to mitigate this challenge.Design/methodology/approachThe approach outlined in this paper specifically addresses BIM deficiencies at the conceptual design stage, where the core drivers and indicators of BIM and generative design are identified and mapped into a generative BIM (G-BIM) framework and subsequently embedded into a G-BIM prototype. This actively engages generative design methods into a single dynamic BIM environment to support the early conceptual design process. The developed prototype followed the CIFE “horseshoe” methodology of aligning theoretical research with scientific methods to procure architecture, construction and engineering (AEC)-based solutions. This G-BIM prototype was also tested and validated through a focus group workshop engaging five AEC domain experts.FindingsThe G-BIM prototype presents a valuable set of rubrics to support the conceptual design stage using generative design. It benefits from the advanced features of BIM tools in relation to illustration and collaboration (coupled with BIM's parametric change management features).Research limitations/implicationsThis prototype has been evaluated through multiple projects and scenarios. However, additional test data is needed to further improve system veracity using conventional and non-standard real-life design settings (and contexts). This will be reported in later works.Originality/valueOriginality and value rest with addressing the shortcomings of previous research on automation during the design process. It also addresses novel computational issues relating to the implementation of generative design systems, where, for example, instead of engaging static and formal description of the domain concepts, G-BIM actively enhances the applicability of BIM during the early design stages to generate optimised (and more purposeful) design solutions.
