Product Realization

Virtual Reality (VR) technology holds promise as a virtual prototyping tool for mechanical assembly; however, several developmental challenges still need to be addressed before virtual prototyping applications can successfully be integrated into the product realization process. This paper describes the development of SHARP (System for Haptic Assembly & Realistic Prototyping), a portable VR interface for virtual assembly. SHARP uses physically-based modeling for simulating realistic part-to-part and hand-to-part interactions in virtual environments. A dual handed haptic interface for realistic part interaction using the PHANToM® haptic devices is presented. The capability of creating subassemblies enhances the application’s ability to handle a wide variety of assembly scenarios. Swept volumes are implemented for addressing maintainability issues and a network module is added for communicating with different VR systems at dispersed geographic locations. Support for various types of VR systems allows an easy integration of SHARP into the product realization process resulting in faster product development, faster identification of assembly and design issues and a more efficient and less costly product design process.

Abstract The process by which new products are brought to market — the product realization process, or PRP — can be introduced in engineering design education. In industry, the PRP has been evolving to concurrent engineering and product teams. The PRP includes components such as concept generation, analysis, manufacturing process development and customer interaction. Also, it involves the sequencing of the components and their connections which includes teamwork, project planning, meetings, reports and presentations. A capstone senior engineering project, along with classroom lectures and presentations can be structured to provide knowledge and experience to the students in many of the PRP components and the connections. This paper will give an overview of the PRP and a project/lecture structure at the author’s university. The instructor recently joined the academic ranks after years in industry with responsibility for directing product development and R&D and for leading product development teams.

Product Realization

Developments in digital technology and manufacturing processes have expanded the horizon of designer innovation in creating products. In addition to this, real-time collaborative platforms help designers shorten the product development cycle by enabling collaborations with domain experts from concept generation to product realization and after-market. These collaborations are extending beyond enterprise and national boundaries, contributing to a growing concern among designers regarding the security of their sensitive information such as intellectual property (IP) and trade secrets. The source of such sensitive information leaks could be external (e.g., hacker) or internal (e.g., disgruntled employee) to the collaboration. From a designer's perspective, this fear can inhibit participation in a collaboration even though it might result in better products or services. In this paper, we aim to contextualize this evolving security space by discussing various security practices in digital domains, such as encryption and secret sharing, as well as manufacturing domains, such as physically unclonable function (PUF) and physical part watermarking for anticounterfeiting and tamper evidence purposes. Further, we classify these practices with respect to their performance against different adversarial models for different stages in product development. Such a classification can help designers to make informed decisions regarding security practices during the product realization process.

A flexible information model for systematic development and deployment of product families during all phases of the product realization process is crucial for product-oriented organizations. In this paper we propose a unified information model to capture, share, and organize product design contents, concepts, and contexts across different phases of the product realization process using a web ontology language (OWL) representation. Representing product families by preconceived common ontologies shows promise in promoting component sharing while facilitating search and exploration of design information over various phases and spanning multiple products in a family. Three distinct types of design information, namely, (1) customer needs, (2) product functions, and (3) product components captured during different phases of the product realization process, are considered in this paper to demonstrate the proposed information model. Product vector and function component mapping matrices along with the common ontologies are utilized for designer-initiated information exploration and aggregation. As a demonstration, six products from a family of power tools are represented in OWL DL (Description Logic) format, capturing distinct information needed during the various phases of product realization.

Product Realization

Many small and medium sized companies base their business strategy on their manufacturing processes. They are highly specialized in areas such as: die-casting, extrusion, machining, sintering, injection molding etc. The specialization is usually also focused on a limited number of material and alloys for the manufacturing process in question. These companies are commonly acting as subcontractors to other companies, original equipment manufacturers (OEMs). For the OEMs to be able to provide affordable products in a short time and to be at the competitive edge, every new design must be adapted to existing production facilities. In order to ensure this, collaboration between engineering design, at the OEM, and production engineering, at the subcontractors, has to be supported. With the dispersed organizations of today and the increasing amount of information that has to be shared and managed in the product realization process, this collaboration is a critical issue for many companies. A more intense collaboration is sought by many subcontractors as it will strengthen the business relation. To provide manufacturing knowledge and to be a partner in the product realization process is a means to outplay competitors. The purpose of this work is to investigate, explore, and develop a computerized method, i.e. an application system, to support the process planning and cost estimation in the quotation process. The main objective is to reveal concepts and principles to support application system development and utilization. The results are based on the experiences from a case study at a subcontractor of turned components.

The Physical Realization

The term Product realization is usually used to describe the physical realization of a product in the product development cycle. Therefore, the term may or may not include conceptualization and design phases. Considering that product realization means bringing a product to reality, it is important to study the concept of reality to understand the role of conceptualization, design, and manufacturing in product realization. In this paper, the concept of reality is expanded to include the perceptual and virtual realities as integral parts of the product realization process. This paper discusses the three phases of realization and their interactions. It also addresses the key roles of conceptualization, design and manufacturability in the realization process. To illustrate the concepts, presented in the paper, some examples are included.

Product Realization

Product realization, which is the goal of any product development process from concept to production, usually means bringing a product to physical reality. Problem solving and design are two of the engineering activities for achieving the product development process goal. For this reason engineering education efforts are usually focused on problem solving as a building block for any educational course or program activities. In addition, some courses and curriculum threads are usually dedicated to design education and practices. The common restriction of realization to mean physical reality, however, limits the full understanding and potential of better problem solving and design education in engineering. In this paper, the realization process is expanded to include the virtual and perceptual realities as valid domains of the product realization process. These domains of realization and their interactions with the physical reality are studied. Also, the relationships between research, problem solving, and design are examined in the context of engineering product realization. Focus, in this study, is directed to the understanding of research, engineering problem solving, and design activities as a result of the expanded realization concept. This understanding aims at improving engineering education by focusing on the key issue of creativity in program and course design, delivery, and assessment. To illustrate the concepts, presented in the paper, several examples are included.

This paper describes a new approach to teaching first year design at Memorial University. Students are introduced to engineering design using the product realization process (PRP) as a platform. The course integrates the business, engineering design, and prototyping functions of the PRP. The just-in-time structured delivery of background tools and theory complement the relatively unstructured nature of the design problems. Lab exercises are used to intoduce the basic practicalities of mechanical, electrical and electronic design. Projects are completed in teams with emphasis placed on teamwork, project management and communication skills. Student enthusiasm has been very high and this aides significantly in the learning process.

Information Requests

Geographically distributed engineers must collaboratively develop, build and test solutions to design-manufacture problems to be competitive in the global marketplace. Engineers operate in a distributed system in which separate entities communicate cooperatively—ideas and information requests are generated anywhere within the system, rapid turn-around is essential, and multiple projects must be handled simultaneously. In this paper we present a prototype platform-independent framework to integrate distributed and heterogeneous software resources to support the computationally intensive activities in the product realization process. This framework, PRE-RMI, is based on an experimental event-based communications model; it has been coded in Java and uses the RMI messaging system. We describe its usage in a distributed product realization environment, the Rapid Tooling TestBed. PRE-RMI is compared to a previous environment, called P2 that was based on Java Servlet technology. PRE-RMI is adaptable to different design processes, is modular and extensible, is robust to network and computing failures, and is far preferable to P2. Further, we demonstrate the successful integration of CAD, CAE, design, and manufacturing software tools and resources in this flexible distributed computing environment.
