Knowledge Based Design

Abstract Pedal packaging is a complex and tedious design process involving trade-offs among many related activities, including driver placement and engine compartment layout. Pedal layout design requires checks of candidate designs against large libraries of standards. Designers of pedal assemblies must carefully follow these regulations and standards, and manually come up with the pedal layout design. Differences in interpretation of the regulations result in inconsistent designs. A knowledge-based design assistant, named PEDAL, has been designed and developed to help automotive package designers overcome these problems. This paper reviews the needs of the pedal package designer in the framework of the abilities of knowledge-based engineering. PEDAL’s prototype implementation and its combined knowledge base of design standards are described.

Use Of Knowledge

Competitive pressures are forcing manufacturers of turbine engines to reduce product development times, minimize design iterations, and react rapidly to changing markets and customers. Concurrent Engineering replaces the traditional sequential design process with parallel efforts in multiple disciplines, increasing product quality while reducing leadtime. Knowledge-Based Engineering captures product and process knowledge contained in the “corporate memory” to enhance and accelerate the design process. Linking the two together provides a wide variety of synergistic effects not separately available. In this paper a general description of the process used to create a Knowledge Based Engineering (KBE) System capable of Concurrent Engineering (CE) will be presented, along with selected results. The summary discusses use of the system created to pursue real world design problems.

This article focuses on the optimization of a design process, in the context of automotive subcontracting opportunity. This optimization is guided by the underlying manufacturing process and by the industrial knowledge. We first show that the actual design studies are biased by the final goal (a formal design) and do not take into account early industrial needs (a draft design to draw up an estimate). We then demonstrate how an automaker subcontractor optimizes the early design process thanks to industrial knowledge.

HighlightsA knowledge-based rapid design system for combine chassis is proposed.Object-oriented knowledge representation uniformly describes the multi-source heterogeneous design knowledge.Multivariate linear regression analysis ratiocinates further unknown design principles behind existing products.Abstract. In the design of agricultural machinery, the lack of systematic and structured knowledge utilization systems results in low development efficiency and poor reusability of design knowledge. This study considers the design of a combine chassis and focuses on the application of knowledge-based rapid design to agricultural machinery. As a typical sophisticated agricultural machine, combines have a complicated design that requires the integration of multiple disciplines according to the crop types, production areas, and ability of the designers. Hence, a knowledge-based design system for a wheeled combine chassis is proposed. By integrating object-oriented technology with a mixed reasoning strategy, multi-source heterogeneous design knowledge can be applied in completing the chassis design task. To date, there are more than 2000 design ideas and 350 parameter models in the knowledge database. In addition, tacit design knowledge acquired by a knowledge discovery method can be employed to perfect the design and improve the reliability of the product. The design of a combine chassis demonstrates that the knowledge-based rapid design of agricultural machinery is completely feasible, and the design system significantly reduces the design workload, shortens the development cycle, and improves design efficiency and knowledge utilization.

This paper presents a knowledge based CAD/CAE integrated multidisciplinary design system. The CAD and CAE models of the major parts of products are established with a set of parameters input from the user interface (UI). The knowledge base and inference engine were constructed to determine the parameters. The system contained self developed modules and commercial CAD/CAE software. It automated the design process and eased the capacity of complicated engineering analysis of the designers and reduced the time for computation. A case study on a roof cover in turbine was carried out to verify the feasibility of this system. The results showed that the developed system facilitated the multidisciplinary design.

Purpose This paper aims to present a knowledge-based fuel system, implementation and application, oriented towards its use in aircraft conceptual design. Design/methodology/approach Methodology and software tools oriented to knowledge-based engineering applications (MOKA) is used as a foundation for the implementation and integration of fuel systems. Findings Including fuel systems earlier in the design process creates an opportunity to optimize it and obtain better solutions by allocating suitable locations in an aircraft, thereby reflecting on the centre of gravity of the aircraft. Research limitations/implications All geometries are symbolic, representing a space allocation inside the aircraft for the fuel system. A realistic representation of the real components could be realized in detail design. Practical implications Fuel weight is a significant part of take-off weight and decisive in aircraft sizing and range estimations. The three-dimensional geometry provides a better estimation of the volume that is available to allocate the necessary entities. It also provides fast measures for weight and balance, fuel capacity, relative tank positions and a first estimation of piping length. Originality/value Fuel systems appear early in the design process, as they are involved in several first estimations. By using a knowledge-based engineering approach, several alternatives can be visualized and estimated in the conceptual design process. Furthermore, using the weights and centre of gravity at different angles of pitch and roll of each fuel tank, the aircraft could be optimized for handling qualities by using automatically generated system simulation models.

Abstract The design process can be divided into different phases. The best order in which the designer should execute these steps remains difficult to predict. In principle, conventional computer programs can only be applied to problems for which algorithms are available. Therefore, in many fields the design process did not allow computer support. The technology of knowledge-based systems has led to new perspectives. However, knowledge-based systems can only be utilized if the well-established design aid, CAD system, is integrated into the concept of knowledge-based computer support. Conceptual considerations and new approaches to linking a CAD system to an expert system, which assists the designer in solving kinematic problems, especially in the conceptual phase, are presented.

Knowledge Based Design

Abstract Micromachine technology has developed in recent years significantly and become an outstanding research field with remarkable results. In the past, several new products resulted, mainly related with sensors, actuators, and medical apparatus. The characteristics of micromachines are given by the interaction of miniaturised mechanical and electronic components, which are manufactured by methods originally developed for semiconductor production. These characteristics of micromachines are taken as occasion to investigate the possibilities of supporting the micromachine design process with knowledge based systems. After a short introduction into knowledge based design systems and design methodologies, a case study on the micromachine design is presented. We will mainly examine the conceptual design stage based on the methodological design. From the case study, specific requirements for a design environment to support the micromachine design process are derived. These requirements are compared with the capabilities offered by today’s concepts for advanced design systems such as SYSFUND. Then, the necessary enhancement for SYSFUND that was found in the process of knowledge representation is described. Finally an extended concept for a micromachine design environment is discussed.

Abstract An emerging technology known as Knowledge-Based Engineering (KBE) is the next step beyond CAD for product representation. KBE allows a true virtual prototype to be developed that represents both the geometric and the non-geometric characteristics of a product. A graduate level design course based on this technology is described. A new version of the design process is presented for the development of a virtual prototype. Examples of a product that was modeled, a hand held vacuum, are also presented.
