Résumé :
The conventional engineering design process consisting of three phases, synthesis, analysis and evaluation can be extended for solving rehabilitation problems by including a diagnosis phase during which abnormalities and malfunctions are identified and characterized. After diagnosis, the design objectives are clearly specified and the conventional engineering design process can begin. Different problem solving strategies, information representation, and processing are useful for the different phases of rehabilitation design. This paper describes the RETAIN knowledge-based rehabilitation design system which integrates a relational database, production rules and algorithmic functions. RETAIN diagnoses retaining wall failures and synthesizes preliminary rehabilitation designs and cost estimates. Its framework and methodology may be applied to other infrastructure components such as pavements, water and sewage networks, bridge piers and marine structures. RETAIN decomposes rehabilitation problems into influencing failure modes then identifies a set of rehabilitation strategies such that each strategy remedies one or more failure modes. Complete rehabilitation solutions are formed by searching and combining strategy components. Conceptual knowledge for design synthesis is organized in relational database tables. The paper includes an example of design synthesis with relational operations for selecting rehabilitation strategies and forming complete rehabilitation solutions.

Résumé :
Computer-aided conceptual design of mechatronic products is becoming more and more important since it offers much convenience in design scheme retrieval and enhances the utilization of existing designs. One of the key technologies for computer-aided conceptual design is an efficient search algorithm for retrieving existing designs. As such, it’s necessary to find a feasible way to select the most suitable design out of a number of candidates for further development. By applying behavioral modeling method for representation of conceptual design, this paper proposes a node matching algorithm for searching behavioral model, together with a model similarity evaluation method. Based on these methods, a framework for computer-aided conceptual design is subsequently proposed. Finally, a case study is presented to illustrate the applicability of the proposed methodologies.

Résumé :
The product form design activities involve a high degree of uncertainty and complexity and are therefore not easily formulated, coded and regularized. Consequently, very few of the computer-aided design approaches presented in the literature can support the conceptual form design tasks typically performed at the preliminary stages of a product’s development cycle. To enable designers to perform their design activities more objectively and efficiently, this paper combines the principles of fuzzy set theory, the shape-blending method and genetic algorithms to generate a knowledge-based approach for product form design based upon a database describing the relationships between different product forms and their corresponding perceptual image evaluations.

Résumé :
This paper presents a study developing a model of the ontology of an apparel product and the design thereof. Here, “ontology” means the concepts and relationships between them for apparel and apparel design; ontology models are also called conceptual models. To the best of our knowledge, such a model has not yet been made in the literature of apparel and apparel design. A conceptual model is a foundation for (1) effective human-human communication and collaboration, (2) facilitating the communication among different computer programs for computer-aided design (CAD) of apparel products, and (3) facilitating human-computer interactions necessary to design an apparel product. The conceptual model developed completely captures the semantics of apparel and design, including the 2D pattern and 3D apparel product. An example is presented, providing an impression of the usefulness of this model.

Résumé :
AbstractAlthough there has been considerable computer-aided conceptual design research, most of the proposed approaches are domain specific and can merely achieve conceptual design of energy flows-processing systems. Therefore, this research is devoted to the development of a general (i.e., domain-independent) and knowledge-based methodology that can search in a wide multidisciplinary solution space for suitable solution principles for desired material-flow processing functions without designers' biases toward familiar solution principles. It first proposes an ontology-based approach for representing desired material-flow processing functions in a formal and unambiguous manner. Then a rule-based approach is proposed to represent the functional knowledge of a known solution principle in a general and flexible manner. Thereafter, a simulation-based retrieval approach is developed, which can search for suitable solution principles for desired material-flow processing functions. The proposed approaches have been implemented as a computer-aided conceptual design system for test. The conceptual design of a coin-sorting device demonstrates that our functional representation methodology can make the proposed computer-aided conceptual design system to effectively and precisely retrieve suitable solution principles for a desired material-flow processing function.

Abstract A methodology has been developed to integrate the vulnerability discipline into the conceptual/preliminary design process of combat aircraft. An interactive and programmable solid modelling Computer Aided Design (CAD) system is used to generate a CAD solid model of the aircraft’s critical components. The aircraft’s components’ sizes and shapes are pre-defined by a conceptual/preliminary design synthesis computer model. A systematic Child-Parent assembly process is used to model the aircraft vulnerability, by defining the criticality degree of each component in the aircraft assembly. Solid Modelling CAD techniques have been modified to develop techniques to perform the two main standard vulnerability assessments, namely the shotline and vulnerable area methods.

Abstract This paper studies the conceptual design of MC (machining center), and the main findings are as follows: The RW (representative workpiece) is the data source of designing an MC. The mechanical matrix of an MC can be figured out by the requirement arising from NC manufacturing of the RW, in which the layout of an MC matrix is constructed with the FPCNMT (functional parts consisting of an NC machine tool). In any CAD system, the design jobs of an MC’s layout involve three different fields. The first work deals with the preconstruction of the feature-model repository of FPCNMT, and the methods of building the repository are introduced by the author. The second design issue focuses on the construction of the mechanical matrix of an MC, in which the writer presents assembling the matrix by calling the FPCNMT based on the PP of a RW. The last job involves correctness and optimum of the layout design of the MC.

The paper reports the problems in automation of designing hydraulic jacks of oneway action. The analysis of methods of computeraided design systems creation is carried out and the algorithms of allowing the formation of a system for computer-aided design of hydraulic jacks are under development. A conceptual approach to a jack choice depending on conditions of its operation allows reducing time for the analysis of requirements specification. In the course of the work with the system there were developed eight basic modules of the system. These modules allow reducing considerably time for the technical documentation development essential for manufacturing jacks with oneway operation and decreasing other costs in the course of designing. Databases created store all the essential information for the proper work of basis modules and also that of standard products, 3 D parametric models and associative drawings. The system developed meets all the requirements imposed on CADs. It is applicable at enterprises engaged in production and repair of hydraulic equipment. The Hydraulic Jack CAD was tested at a functioning enterprise and justified hopes.

This paper, proposes a method that designers provide a basic conceptual form scheme of the products with multi- deformation channel, but a detailed form is modified by the users according to the locally changeable two or three dimensional models, and the needed several product form schemes can be achieved through statistic analysis of the feedbacks from the users. In this process, users redesign the form in the mean while of product evaluation, which makes the users have a good knowledge of the products and makes the designers get the direct statistics of the most desirable morph from the perspective of the users. This method combines the evaluation and design process together, which is able to promote the batter communication, thus to make design process more efficient.

Résumé :
The selection of mechanism type is one of the important aspects in conceptual design of machine products. The paper applies the set theory for representing the attribute items of kinematic function to reflect the kinematic state and the function quality to reflect overall performances of the function unit for some complex design task. It gives a set-theory-based mode for the selection of mechanism types, in which precise reasoning by computer is combined with fuzzy appraisement by human. By precise reasoning at first, the computer selects from mechanisms database those mechanisms that can meet the kinematic requirements of the function unit to be solved. And then the function qualities of the selected mechanisms are appraised by human approving, which is actually a process of fuzzy match. This approach avoided the difficulty that the computer cannot yet effectively process fuzzy information and is suitable for the selection of both single-degree-of-freedom (DOF) and many-DOF mechanisms. The selected mechanisms can thus meet the requirements not only of the kinematic function, but also of the function quality. The approach presented in the current paper has been successfully applied to the software development of computer-aided conceptual design of mechanism systems.

Résumé :
Conceptual design process is considered as the most critical and important phase of product design process. It is the stage where product’s fundamental features are determined, large proportion of the lifecycle cost of the product is committed, and other major decisions are made, which have significant impact on the downstream design and related manufacturing processes. It is also a knowledge intensive process where diverse knowledge and several years of experience are put together to design quality and cost effective products. Unfortunately, computer support systems for this phase are lagging behind compared to the currently available commercial computer aided design (CAD) tools for the later stage of design. This paper proposes a knowledge-based conceptual design support system in which design concepts from existing products and previous experiences are captured and used to design future products. The conceptual design support system will assist designers during the conceptual design process by generating concepts on a morphology chart and handling some of the repetitive tasks. In addition, the generated concepts may inspire designers to generate new concepts. The design support system addresses the key features of conceptual design process such as functional analysis, concept generation and concept evaluation with aid of the production rules within the knowledge-based system.

Résumé :
Conceptual design is the most creative and important stage in product design process. A computer-aided creative design (CACD) system is indispensable to provide effective support for human-oriented creative behavior and iterative decision-making during the conceptual design process. Based on cognition and iteration, this study proposes a triplhelix innovative solving model to guide the construction of CACD system. In this model, three types of space are established, including design flow space as reference for mapping direction, knowledge inspiration space as source of stimulus information, and solution operating space as carrier. The cooperation among the triple space is organized based on memory information processing theory, so as to inspire designers’ cognitive thinking to generate product solutions. In addition, the iterative operations of design elements among function, behavior, and structure utilizing the proposed triple space are discussed. With this model, the designers can develop multiple innovative solutions according to expected design types (variant, adaptive, original), and different cognitive stimulation (extension, analogy, mutation) of design knowledge can also be obtained. Then, a prototype system of computer-aided creative design platform is developed to implement this innovative solving model. Finally, a design case of espresso machine is presented to demonstrate the practicability and validity of the prototype system.

Résumé :
.Amid the fierce rising competition in the market, accelerating the problem solving and decision making process have become major issues in product design especially in conceptual design stage. For years, Theory of Inventive Problem Solving (TRIZ) has been extensively applied in problem solving. In this paper, Analytical Hierarchy Process (AHP) was proposed to strengthen three major steps in TRIZ methodology namely as problem definition, root cause identification and solution generation. The integration was then structured in the form of computer-based system. The integration, application and software in AHP and TRIZ method have been discussed in this paper. This proposed support system not only provided evidence that TRIZ methodologies improved by the support of AHP and also aided the designers in early design phase such as concept, process and material selection.

Résumé :
With the sharpness of market competition, the design of automobile outline becomes more and more important. By far, no systematic method can direct designers to carry out creative design orderly. In fact, most of the instances are created by designers’ cerebrum independently. The rise of the evolution computation provides us a new approach for conceptual creative design; therefore, it has become one of the most important techniques for computational and creative design. This paper pays more attention to the computer aided environment in the automobile outline design, proposes the automobile outline modularization design method and classifies component base into two categories. This method stores the data in the format of XML, which can save great memory and amount of rebuild component time.

Résumé :
AbstractThis paper presents a preliminary comparison between the role of computer-aided design (CAD) and sketching in engineering through a case study of a senior design project and interviews with industry and academia. The design team consisted of four senior level mechanical engineering students each with less than 1 year of professional experience are observed while completing an industry sponsored mechanical engineering capstone design project across a 17 week semester. Factors investigated include what CAD tools are used, when in the design process they are implemented, the justification for their use from the students' perspectives, the actual knowledge gained from their use, the impact on the final designed artifact, and the contributions of any sketches generated. At each design step, comparisons are made between CAD and sketching. The students implemented CAD tools at the onset of the project, generally failing to realize gains in design efficiency or effectiveness in the early conceptual phases of the design process. As the design became more concrete, the team was able to recognize clear gains in both efficiency and effectiveness through the use of computer assisted design programs. This study is augmented by interviews with novice and experienced industry users and academic instructors to align the trends observed in the case study with industry practice and educational emphasis. A disconnect in the perceived capability of CAD tools was found between novice and experienced user groups. Opinions on the importance of sketching skills differed between novice educators and novice industry professionals, suggesting that there is a change of opinion as to the importance of sketching formed when recent graduates transition from academia to industry. The results suggest that there is a need to emphasize the importance of sketching and a deeper understanding as to the true utility of CAD tools at each stage of the design process.

Résumé :
In this paper, a conceptual design of a Delta robot is developed by means of a mechatronic design methodology. A fully integrated conceptual design, clarifying the recurrence of the conceptual design process using black-box/white-box analysis, is presented using the Model Based Systems Engineering (MBSE) paradigm and the SysML language as the formal modeling tool. Multiple designs proposals are then evaluated by the non-linear Choquet integral in order to choose the most appropriate according to a multicriteria requirement. For a preliminary conceptual design, structural parameters for the Delta robot are determined by defining and solving a nonlinear constrained optimization problem, which considers the kinematic model of the robot maximizing its workspace. Both the decision making and the optimization problem are integrated and automated into a common software framework for the design process, by using a standard genetic algorithm and Monte Carlo method to set the optimized conceptual design to be rendered in Computer Aided Design (CAD) software and in a physical prototype, satisfying the technical specifications.

Résumé :
During conceptual design of systems, the emphasis is on generating the system architecture: the configuration of sub-systems and the interactions between them. Ports, as locations of intended interaction, play an important role at this stage of design. They are convenient abstractions for representing the intended exchange of signals, energy or material; they can be applied at different levels of detail, across different energy domains, and to all aspects of design: form, function, and behavior. But to play this versatile role, ports need to be represented in an unambiguous yet flexible fashion, accommodating the differences in vocabulary and approach across different disciplines and perspectives. In this article, we introduce the semantic structure for such an unambiguous representation: a port ontology. The ontology formalizes the conceptualization of ports such that engineers and computer aided design applications can reason about component connections and interactions in system configuration. It defines ports in terms of form, function and behavior attributes and further includes axioms that can be used to support a variety of engineering design tasks, such as port refinement, port compatibility checking, and the instantiation of interaction models. A LEGO example is used to illustrate the ontology and its applications in conceptual design.

Résumé :
Exploring wide multi-disciplinary solution spaces to create conceptual design solutions is a difficult task for human designers due to lack of sufficient multi-disciplinary knowledge. A viable approach would be to develop a computer-aided system to synthesize the wide variety of knowledge for a given design task. However, the existing design synthesis systems are mainly domain-specific, focusing on conceptual design synthesis in a single or few limited disciplines. Therefore, this article introduces the development of a knowledge-based system for multi-disciplinary conceptual design synthesis, including the establishment of a knowledge base for organizing multi-disciplinary principle solutions and a design synthesis algorithm. The implementation of a prototype software is also reported, with the conceptual design of a solar fountain as a demonstrative case. The results of the case study show that the system can automatically and conveniently generate multi-disciplinary conceptual solutions.
