Engineering conceptual design can be defined as that phase of the product development process during which the designer takes a specification for a product to be designed and generates many broad solutions to it. This paper presents a constraint-based approach to supporting interactive conceptual design. The approach is based on an expressive and general technique for modeling: the design knowledge that a designer can exploit during a design project; the life-cycle environment that the final product faces; the design specification that defines the set of requirements the product must satisfy; and the structure of the various schemes that are developed by the designer. A computational reasoning environment based on constraint filtering is proposed as the basis of an interactive design support tool. Using such a tool, human designers can be assisted in interactively developing and evaluating a set of schemes that satisfy the various constraints imposed on the design.

Design Support Tool

National Maritime Research Institute of Japan (NMRI) has been developing the integrated design support tool, called “Harmonic Design Tool”, for evaluating economical / safe / environmental aspects of the offshore platform. We are also conducting the conceptual design of the offshore platforms for assessing the availability and accuracy of this design support tool. Seafloor massive sulphides (SMS) are high-grade hydrothermal deposits rich in copper, zinc and lead with a high gold and silver content. The Japanese Economic Exclusive Zone (EEZ) is well known to have high potential of SMS. Thus we decided the SMS mining as one of the most promising applications for the offshore platform technologies. Based on the published potential map of resources and the metocean database established in this project, we decided Izu-Bonin Arc as the target sea area and derived the design and operation conditions for the offshore mining platform. Then we proceeded to the basic concept such as the production rate and storage capacity, dynamic positioning system for station keeping and operation availability. This paper presents the review of the conceptual design of the offshore platform for SMS mining.

Abstract This paper describes a decision support tool that can help a product development team reduce manufacturing cycle time during product design. This design for production (DFP) tool determines how manufacturing a new product design affects the performance of the manufacturing system by analyzing the capacity requirements and estimating the manufacturing cycle times. Performing these tasks early in the product development process can reduce product development time. The paper presents a comprehensive DFP approach and describes the components of the DFP tool, which gives feedback that can be used to eliminate manufacturing cycle time problems. We present an example that illustrates the tool’s functionality.

Holistic Description

The conceivable evolution of information technology will enable mechatronic systems with inherent partial intelligence. We call this kind of systems self-optimizing. Self-optimizing systems are able to react autonomously and flexible to changing environmental conditions. They are capable of learning and optimizing their behavior at run-time. This paper presents the paradigm of self-optimization and shows how to develop self-optimizing systems. Focus is the conceptual design phase. The result of this phase is the principle solution. In this paper at first we explain how to describe the principle solution in a domain-spanning way. This is of high importance because a holistic description of the principle solution constitutes the basis for the communication and cooperation between the engineers from different domains who are engaged in developing a self-optimizing system. At second we introduce solution patterns for developing principle solutions. Solution patterns enable the reuse of design knowledge so that the development process will be more effective. This paper focuses on solution patterns including self-optimizing solutions. How the methods work we explain by the complex magnetic linear drive of a shuttle.

Hierarchy Process

Pemilihan konsep reka bentuk yang sesuai di peringkat reka bentuk gagasan dalam proses pembangunan produk adalah merupakan keputusan yang genting. Keputusan yang tidak tepat boleh menyebabkan sesuatu produk itu perlu direka bentuk semula atau dikilang semula. Salah satu daripada keadah yang boleh digunakan dalam menentukan konsep reka bentuk yang paling sesuai adalah process hierarki beranalitis (AHP). AHP telah digunakan dalam hampir kesemua aplikasi yang berkaitan dengan membuat sesuatu keputusan. Dalam kertas kerja ini, hasil daripada kajian kes menunjukkan bahawa konsep AHP boleh membantu pereka bentuk untuk membuat penilaian secara berkesan daripada pelbagai konsep reka bentuk di peringkat reka bentuk gagasan. Kertas kerja ini memaparkan kaedah pemilihan konsep reka bentuk dengan menggunakan proses hierarki beranalitis. Kata kunci: Process hierarki beranalitis; reka bentuk gagasan; proses pembangunan produk; perbandingan pasangan; pembangunan kerusi roda Selecting the right design concept at conceptual design stage in product development process is a crucial decision. Inaccurate decision can cause the product to be redesigned or remanufactured. One of the useful tools that can be employed in determining the most appropriate design concept is Analytical Hierarchy Process (AHP). AHP has been employed in almost all applications related to decision–making problems. In this paper, the results of a case study illustrates that AHP concept can assist designers to effectively evaluate various conceptual design alternatives at the conceptual design stage. This paper presents the methodology of selecting design concepts using analytical hierarchy process.

Changing Role

In recent years, the benefits of using FEA or design analysis as part of conceptual design have become apparent. The direct involvement of design engineers in analyzing their own designs allows for quick turnaround times and ensures that design modifications indicated by analysis results are promptly implemented in the design progress. Used properly, it yields trustworthy results that are already driving efficiencies and cost savings in industries ranging from consumer goods to automotive. This paper will outline the advances in technology which have made this change possible.
