Abstract Internet technology opens up another domain for building future CAD/CAM environment. The environment will be global, network-centric, and spatially distributed. In this paper, we present a new approach to network-centric virtual prototyping (NetVP) in a distributed design environment. The presented approach combines the current virtual assembly modeling and analysis technique with distributed computing and communication technology for supporting virtual prototyping activities over the network. This paper focuses on interoperability, shape representation, and geometric processing for distributed virtual prototyping. STEP standard and CORBA-based interfaces allow the bi-directional communication between the CAD model and virtual prototyping model, which makes it possible to solve the problems of interoperability, heterogeneity of platforms, and data sharing. STEP AP203 is utilized as a means of transferring and sharing product models. In addition, Attributed Abstracted B-rep (AAB) is introduced as 3D shape abstraction for transparent and efficient transmission of 3D models and for the maintenance of naming consistency between CAD models and virtual prototyping models over the network. Further, this paper discusses geometric processings needed for distributed virtual prototyping activities such as collision detection and interactive assembly modeling.

Developments in simulation technology that enable a qualitatively new virtual prototyping approach to design of mechanical systems are summarized and their integration into an engineering design environment is illustrated. Simulation tools and their enabling technologies are presented in the context of vehicle design, with references to the literature provided. Their implementation for design representation, real-time driver-in-the-loop simulation, dynamic performance simulation, dynamic stress and life prediction, maintainability analysis, design sensitivity analysis, and design optimization is outlined. A testbed comprised of computer aided engineering tools and a design level of fidelity driving simulator that has been developed to demonstrate the feasibility of virtual prototyping simulation for mechanical system design is presented. Two 1994 demonstrations of this capability for vehicle design are presented, to illustrate the state of the technology and to identify challenges that remain in making virtual prototyping simulation an integral part of mechanical system design in US industry.

The design and test of Multi-Processor System-on-Chips (MPSoCs) and development of distributed applications and/or operating systems executed on those hardware platforms is one of the biggest challenges in today’s system design. This applies in particular when short time-to-market constraints impose serious limitations on the exploration of the design space. The use of virtual platforms can help in decreasing the development and test cycles. In this paper, we present a cloud-based environment supporting the user in designing heterogeneous MPSoCs and developing distributed applications. Therefore, the design environment generates virtual platforms automatically allowing fast prototyping cycles especially in the software development process, and exports the design to a hardware flow synthesizing compatible FPGA designs. The extension of the peripheral models with debug information supports the developer during test and debug cycles and avoids the need of adding special debug codes in the application. This improves the <br />readability, portability and maintainability of produced software. Additionally, this paper presents the benefits of using cloud-based design environments in engineers’ trainings and educations. Therefore, the framework supports testing the system including complex software stacks with prerecorded data or testbenches.

Abstract This paper presents a novel class of human-worn manipulation aids for people with disabilities, and a paradigm for the cost-effective design and manufacture of such devices. These manipulation aids are passive multi-link articulated devices that are physically connected to and controlled by a human user. This physical connection enables proprioceptive feedback control of the end effector. Performance can be enhanced by task and user customization of such devices prior to manufacture. As illustrative examples, we consider two case studies of the design and prototyping of customized manipulation aids for quadriplegics. We explore the use of the virtual prototyping and interactive simulation tools by the designer to customize the designs, virtually analyze the user-product interactions and progressively refine these designed aids. This process is aided by a unified design environment that integrates such support tools as automated data acquisition and measurement, mechanism synthesis and optimization, creation of customized synthetic models of the human user, and the user-based refinement of the product performance.

Common Situation

Universities and corporates, in Europe and the United States, have come to a win-win relationship to accomplish goals that serve research and industry. However, this is not a common situation in Latin America. Knowledge exchange and the co-creation of new projects by applying academic research to solve company problems does not happen naturally.To bridge this gap, the Design School of Universidad de los Andes, together with Avianca, are exploring new formats to understand the knowledge transfer impact in an open innovation network aiming to create fluid channels between different stakeholders. The primary goal was to help Avianca to strengthen their innovation department by apply design methodologies. First, allowing design students to proposed novel solutions for the traveller experience. Then, engaging Avianca employees to learn the design process. These explorations gave the opportunity to the university to apply design research and academic findings in a professional and commercial environment.After one year of collaboration and ten prototypes tested at the airport, we can say that Avianca’s innovation mindset has evolved by implementing a user-centric perspective in the customer experience touch points, building prototypes and quickly iterate. Furthermore, this partnership helped Avianca’s employees to experience a design environment in which they were actively interacting in the innovation process.
