Decision Based Design

Different products necessitate different design processes. Determining which such process is most appropriate for a particular product, in turn, requires its delineation before the design of the product under consideration. The phase where design processes are composed is called meta-design. Despite its importance, current simulation-based design frameworks such as FIPER, ModelCenter, and iSIGHT do not support meta-design. This oversight can be attributed at least in part to the fact that these frameworks capture information about products, design processes, and the associated tools in a lumped fashion. Processes are captured in terms of the specific tools employed and the product information, associated with their use, thereby restricting the re-utilization (i.e., reuse via adaptation or customization) of instantiated processes for designing different products. This inherent inability to separate product and process information hinders the exploration of different design process options for designing a product at a fundamental level, thereby restricting meta-design. In order to address this challenge, we propose an approach for distinctly capturing and processing three key components of design related information - a) design problem, b) design process, and c)product. We term this approach, rooted in decision-based design, modularity, and separation of declarative and procedural information, 3-P. The modular separation of information associated with problem, product, and process enables designers to utilize existing knowledge, captured in the form of pre-defined process configurations, for more effectively designing a given product. The proposed approach facilitates the efficient exploration and reconfiguration of design processes, furnishing a much needed and essential basis for meta-design.

Key Factor

From interviewing developers and analyzing examples from industry, the authors have concluded that communication issues during the design process are a key factor of the complexity of product development. These communication issues stem from a lack of insight in the workflow between designers and their resources, and the lack of insight in the relation of this workflow to the system architecture. To the best knowledge of the authors, currently there are no suitable models and tools that allow capturing and understanding such information in an integrated way. This work contributes by providing requirements for tools and models, and proposes a modeling language that fulfils such requirements. With this language we introduce a method for capturing design process information: The language can combine multiple stakeholder-based views on their system aspects of interest with architectural concerns, and can specify which resources in terms of models and parametric information are needed from other stakeholders to develop these aspects. The language was also developed as a stepping stone for automation of design processes.

Product And Process

In modern automotive manufacturing the data associated with the products and the assembly processes required to build a car are not intelligently linked. This becomes problematic when trying to efficiently create best practice templates for assembly processes because the procedure for linking these best practice assembly processes with vehicle components becomes a daunting task. This research is aimed at the development of a decision support system and cyber infrastructure for efficiently linking product information and process information. Specifically, tools are developed to link product and process information in the automotive industry. The goal of this research is to develop and encode rules to guide the linking of product and process information. These rules are formed from historical data and provide suggestions to process planners as to which variants of parts can be assigned to the same standardized set of assembly instructions which exist as process sheet templates. The part data used consists of a standard text description of the part, the bounding box coordinates for all possible installation locations of the part, a unique identifier for the part, and a logic string which defines valid vehicle configurations such as platforms, models, and options for which the part is valid. A portion of this data is analyzed and used as the basis for development of the part grouping rules. Each rule will compare two parts with respect to the relevant part data and determine whether the two parts are capable of being assigned to the same process sheet. The development of the rules is discussed along with examples, followed with a discussion regarding the implementation of the rules into a prototype system. The rules are tested against part data not used in the development process, and a discussion of the results is presented. The paper concludes with conclusions drawn from testing of the rules and a discussion of future work.

Design Reasoning

AbstractThe mechanism of design reasoning from function to form is suggested to consist of a two-step inference of the innovative abduction type. First is an inference from a desired functional aspect to an idea, concept, or solution principle to satisfy the function. This is followed by a second innovative abduction, from the latest concept to form, structure, or mechanism. The intermediate entity in the logical reasoning, the concept, is thus made explicit, which is significant in following and understanding a specific design process, for educating designers, and to build a logic-based computational model of design. The idea of a two-step abductive reasoning process is developed from the critical examination of several propositions made by others. We use the notion of innovative abduction in design, as opposed to such abduction where the question is about selecting among known alternatives, and we adopt a previously proposed two-step process of abductive reasoning. However, our model is different in that the two abductions used follow the syllogistic pattern of innovative abduction. In addition to using a schematic example from the literature to demonstrate our derivation, we apply the model to an existing, empirically derived method of conceptual design called “parameter analysis” and use two examples of real design processes. The two synthetic steps of the method are shown to follow the proposed double innovative abduction scheme, and the design processes are presented as sequences of double abductions from function to concept and from concept to form, with a subsequent deductive evaluation step.

Abstract As engineering design is subjected to increasingly formal study, an informal attitude continues to surround the topic of iteration. Today there is no standard definition or typology of iteration, no grounding theory, few metrics, and a poor understanding of its role in the design process. Existing literature provides little guidance in investigating issues of design that might be best approached in terms of iteration. We review contributions of existing literature toward the understanding of iteration in design, develop a classification of design iteration, compare iterative aspects of human and automated design, and draw some conclusions concerning management of iteration and approaches to design automation.

Do So

Abstract Most of the previous research efforts for design process modeling had such assumptions as “design as problem solving,” “design as decision making,” and “design by analysis,” and did not explicitly address “design as synthesis.” These views lack notion and understanding about synthesis. Compared with analysis, synthesis is less understood and clarified. This paper discusses our fundamental view on synthesis and approach toward a reasoning framework of design as synthesis. To do so, we observe the designer’s activity and formalize knowledge operations in design processes. From the observation, we propose a hypothetical reasoning framework of design based on multiple model-based reasoning. We discuss the implementation strategy for the framework.

User Hierarchy

The medical device design process has a responsibility to define the characteristics of the object to ensure its correct interaction with users. This study presents a proposal to improve medical device design processes in order to increase user acceptance by considering two key factors: the user hierarchy and the relationship with the patient’s health status. The goal of this study is to address this research gap and to increase design factors with practical suggestions for the design of new medical devices. The results obtained here will help medical device designers make more informed decisions about the functions and features required in the final product during the development stage. In addition, we aim to help researchers with design process didactics that demonstrate the importance of the correct execution of the process and how the factors considered can have an impact on the final product. An experiment was conducted with 40 design engineering students who designed birthing beds via two design processes: the traditional product design process and the new design process based on hierarchies (proposed in this study). The results showed a significant increase in the user acceptance of the new birthing bed developed with the hierarchical-based design process.

Developing Strategies

Designers are increasingly involved in designing alternative futures for their cities, together with or self-organized by citizens. This article discusses the fact that (groups of) citizens often lack the support or negotiation power to engage in or sustain parts of these complex design processes. Therefore the “capabilities” of these citizens to collectively visualize, reflect, and act in these processes need to be strengthened. We discuss our design process of “democratic dialogues” in Traces of Coal—a project that researches and designs together with the citizens an alternative spatial future for a partially obsolete railway track in the Belgian city of Genk. This process is framed in a Participatory Design approach and, more specifically, in what is called “infrastructuring,” or the process of developing strategies for the long-term involvement of participants in the design of spaces, objects, or systems. Based on this process, we developed a typology of how the three clusters of capabilities (i.e., visualize, reflect, and act) are supported through democratic dialogues in PD processes, linking them to the roles of the designer, activities, and used tools.

Different Levels

AbstractThis paper presents a formal analysis of design process dynamics. Such a formal analysis is a prerequisite to come to a formal theory of design and for the development of automated support for the dynamics of design processes. The analysis was geared toward the identification of dynamic design properties at different levels of aggregation. This approach is specifically suitable for component-based design processes. A complicating factor for supporting the design process is that not only the generic properties of design must be specified, but also the language chosen should be rich enough to allow specification of complex properties of the system under design. This requires a language rich enough to operate at these different levels. The Temporal Trace Language used in this paper is suitable for that. The paper shows that the analysis at the level of a design process as a whole and at subprocesses thereof is precise enough to allow for automatic simulation. Simulation allows the modeler to manipulate the specifications of the system under design to better understand the interlevel relationships in his design. The approach is illustrated by an example.
