This paper describes a new design support system that supports conceptual or creative design by dynamically integrating knowledge in different design domains. We argue that abduction for integrating theories can be a basic principle to formalize such design processes. Based on this principle, we propose Universal Abduction Studio, a design environment in which designers combine different theori...

It is not easy for a user of an Information Retrieval (IR) system to select an appropriate keyword set to represent his or her specific information need. Therefore, many IR systems can modify keyword sets by estimating the users particular requirement. Even though such IR systems have better retrieval performance, the complicated estimation process entailed by a large number of keywords makes i...

In this paper, we propose a fundamental idea of a new CAD mechanism to facilitate design knowledge management. This mechanism encourages a designer to externalise his/her knowledge during a design process and facilitates sharing and reuse of such externalised design knowledge in later stages. We also describe the implementation of this idea called DDMS (Design Documentation Management System). ...
In a design process, a designer uses various kinds of design object knowledge, such as physical laws, mechanism library, and manufacturing knowledge. Therefore, it is necessary for a CAD system to handle large scale knowledge bases to support this process. However, it is difficult to use a large scale knowledge base without knowledge about operations of the knowledge itself. This paper proposes...
During design, a designer uses various computational tools, such as a geometric modeling system, analysis tools, and databases. To support these design processes, a system that can integrate such computational tools is required. For this purpose, we have been developing the Knowledge Intensive Engineering Framework (KIEF) system. KIEF enables the designer to build, evaluate, and modify design m...
In this study, we propose a framework of an integrated modeling environment for design. Since a mechanical engineering design process requires various kinds of design object models, such as a geometric model, a kinematic model, and a finite element model, this environment should maintain consistency among these models. Furthermore, commercial design tools are practically used in design processe...
An intelligent CAD system aims at serving a designer as an intelligent, integrated design environment. For building such a system, development of a large scale knowledge base is necessary. To do so, design knowledge must be systematically formalized, made computable, and organized. Design knowledge has two categories ; i.e., design object knowledge and design process knowledge. In our previous ...
In order to realize a creative design, it is thought to be important to unify the different knowledge group flexibly, and the concept of the computer environment which supports designers in an integrated way has been proposed. Our project, called Universal Abduction Studio, aims at assisting designers in obtaining design solutions through the dynamic interaction between a system and a designer....
In order to design new artifacts that are different from existing ones, it is crucial to have new knowledge for the design problem. We have already confirmed that combination of existing knowledge from different domain may useful for this process by analyzing design cases. In this paper, we briefly review our hypothetical knowledge generation support environment "Universal Abduction Studio...
We argue that abduction for integrating theories can be a basic principle to formalize creative design processes. Based on this principle, we have proposed Universal Abduction Studio, a design environment in which designers combine different theories to arrive at better design. In this new approach to computational support of conceptual design, the system should offer various types of abductive...

When a designer confronts a difficult design problem which cannot be solved only with his/her own knowledge, it is necessary to amplify it by introducing new perspectives and ideas for design. The authors have been developing a integrated computer aided design system for creative design. In this report, the authors propose a knowledge description framework which enables computers to analogize a...
Program management aims to support a management for a large and complex project. We have already proposed a framework for supporting this management process by reviewing a program from three different aspects (i.e., process planning, related information, and stake holder networks). However, this system only supports to represent and review a program by using manually inputted information. In th...
It is important to unify different knowledge groups, which exist independently, and to extend knowledge gradually in order to obtain creative design solutions that are not obtained only with the existing design knowledge. With the aim of development of "Universal Abduction Studio", which is a system supporting creative design, a knowledge representation and a matching algorithm for cr...
For tracing or finding the lost goods, we need active-type of RFID tags with built-in batteries, but those active tags have significant drawbacks such as the higher hardware cost and the finite battery lifetime. In this paper, we propose "double-decker" RFID tags, which can be separated into the two parts of ID tags. The new type of RFID tag is useful and cost-effective for tracing/ke...

The objective of upgrade design is to extend product life so as to reduce consumption volume of resources and energy usage. However, difficulty of upgrade design resides within prediction of future trend such as technological trends and market trends, and upgrade design should be robusts against uncertainty of future predection. This paper proposes a design methodology for upgradable products, ...
Since previous designer may already generate possible combination of existing domain knowledge, it is difficult to design creative solution without creating innovative knowledge. We have already confirmed that combination of existing knowledge from different domain may useful for this process by analyzing design cases. In this paper, we propose methodology to generate hypothetical knowledge for...
Although design support systems have been well developed in geometric and detail design areas, they are still not successful in conceptual or creative design domain. In our opinion, the main difficulty is knowledge and its operation that play a crucial role in conceptual design. In this paper, we propose "Universal Abduction Studio" that is a new approach to support designers by compu...

In engineering design research, numerous design process models have already been proposed. For constructing model of synthesis, it is very important to know the position of the model among them. This paper reports results of comparison of some design process models with the synthesis oriented thought process model. We use a reference model as an example of design, compare it with some existing ...
Since design knowledge plays a crucial role in design process, we are conducting research on design reasoning model that takes notice of design knowledge. To make a design reasoning model, we have already proposed a reasoning framework of design and analyzed basic operations for the framework, and then propose a synthesis language for describing design operational knowledge. In this paper, we p...
Since design knowledge plays a crucial role in design process, we are conducting research on design reasoning model that takes notice of design knowledge. To make a design reasoning model, we have already proposed a reasoning framework of design and analyzed basic operations for the framework. However, since these operations are just fragments of whole design process, it is necessary to describ...
In engineering activities, engineers solve various kinds of problems. Most of these problems are routine problems that are easy to formalize and formalized knowledge is useful for these problems. On the other hand, there are complicated problems that is difficult to formalize all of the problem solving process. One of the useful information to solve such complicated problems is result of the si...
Conventional products tend to be thrown away because of functional obsoleteness before reaching the end of physical life of the products. This is one of the main causes of the mass disposal problem. In order to solve this problem, this paper proposes a design methodology for upgradable products. Especially, this paper discusses a method dealing with uncertainty of long-term planning in the desi...
In engineering activities, management of designers' knowledge is becoming crucial to share and reuse it efficiently. Toward this issue, we are studying a methodology to capture the designer's thought process, and to semi-automatically arrange it into a refined document, which addresses a particular objective with particular thought patterns. The key issues of this methodology are to a...
