Capturing, structuring and accessing design rationale in integrated product design and manufacturing processes

Abstract

Developing customized products is the business case for many manufacturing companies striving to fulfill the customers' specific needs. When manufacturing customized products it is often necessary to also develop corresponding customized manufacturing tooling. There is a need to support concurrent development of new product variants along with their manufacturing toolsets. The communication between design engineers and manufacturing engineers is hence a key issue that if solved would enable design engineers to forsee how changes in product design affect tooling design and vice versa. To understand the correlation between the design of a product and its corresponding manufacturing tools, access to design rationale of the product and the developed tooling is required. Design rationale provides an explanation of why an artifact is designed in the way it is, including statements (textual, numerical or geometrical), argumentations, and decisions. Since design rationale is composed of information scattered all across the company's repositories in different formats (e.g. in type of a geometry, picture, table, and textual document), representing the design rationale is a challenge for many enterprises. In this paper a method is introduced that enables capture, structure, and access to design rationale across product design and tooling design. The system enables representing design rationale in formats such as CAD models, spreadsheets, textual formats, and web pages. The method has been examined by developing a prototype system tested in a case company which develops and manufactures customized car accessories, such as roof racks and bike carriers, for different car models. The company develops and manufactures the products as well as the required tooling equipment. The prototype system includes different software commonly used by engineers during designing a product, for the purpose of making it applicable for other companies.

Review Knowledge Manajemen dan Tacit Knowledge Dalam Manufaktur

“…Misal, dalam penelitian [5] proses manufaktur mengunakan bentuk aturan produksi untuk menyediakan pemetaan teknis dan elisitasi pengetahuan diam-diam (Tacit Knowledge) di industri, untuk mempromosikan pemodelan pengetahuan diam-diam ke pengetahuan eksplisit. Studi lain [8] melakukan penelitian untuk memahami korelasi antara perancangan suatu produk dan alat-alat manufaktur yang sesuai. Adapun penelitian ini bertujuan untuk mendapatkan berbagai pemahaman bagaiaman keterlibatan knowledge management dan tacit knowledge dari berbagai tinjauan dalam aspek manufaktur.…”

“…Tacit Knowledge dalam konteks manufaktur juga digunakan dalam aspek desain. Desain adalah proses penting dalam pengembangan produk dan membuat keputusan yang tepat, yang pada tahap awal ini meningkatkan proses pengembangan dan mendukung organisasi untuk memberikan inisiatif bisnis dan tujuan strategis mereka [8]. Desain adalah aktivitas intensif pengetahuan yang sangat bergantung pada pengalaman process engineers, industrial engineers, dan manufacturing equipment engineers, yang membutuhkan cara efisien untuk mengelola pengetahuan yang relevan [19].…”

“…Diantaranya adalah penggunaan aplikasi mobile yang dilakukan oleh D. Mourtzis, etc dalam penelitiannya [24] untuk membantu dalam penyelesaian masalah dibiadang manufaktur berupa instruksi dan pendapat para ahli. Selain itu dalam penelitian [8] mengajukan sebuah prototipe sistem yang membantu dalam memahami korelasi antara desain suatu produk dan peralatan manufaktur yang terkait.…”

A structured approach to defect data management for improving DFM implementation in aerospace manufacturing

“…Although this challenge is widely discussed in literature related to Extended Enterprises [4], Knowledge Management (KM), Collaboration Technology [5], Industry 4.0 [6], and Concurrent Engineering [7], most of the approaches proposed for managing large amounts of different types of data for engineering implementation remain very much top down approaches and mostly attempt to improve the understanding of the subject area; whilst very rarely aim to develop solutions that address how defect data can be used to enable more effective DFM implementations within low volume high value complex industrial context. Nevertheless, a more effective, responsive DFM approach to be achieved based on real-life defect data can play a significant role in enabling engineers to create closedloop design rationales developed from knowledge of manufacturing processes and is critical in reducing development time and costs whilst improving quality [8]. This research adopts this approach by considering how the defect data captured and stored in manufacturing can be used for facilitating DFM implementations and improving design specifications in complex aerospace design and manufacturing context.…”

A Tool for Systematically Accessing the Level of Readiness of Engineering Design in Product Development

“…A design problem as the trigger of the design can be presented in multiple forms: from a rough sketch of an ill-defined problem with little information, to a more detailed problem of application of a patent for different working or manufacturing environment or translation of scientific research findings to a practical application. The design domain can also vary extensively, it can make use of an already developed technology or it might develop a new technology within its domain of development [1]. The huge variability in initiation, the level of analysis and the domain of a particular design, makes the assessment of its level a very complicated task.…”
