In the automotive industry the activities of documenting the design options and generating the necessary request for quotations, for Tier 1 system suppliers to be awarded contracts for design and development, is complex and time-consuming since these activities are predominately manual and paper-based. Thus, a knowledge-based tool is being developed to aid the selection of the design options for vehicle systems during competitive tendering. The tool is based on ontologies in order to provide a common and shared definition for the options available for a given vehicle system. An overview of this approach is provided and, as a ‘proof of concept’, a case study involving seating systems is presented. This paper shows, through the seating system case study, how the functionalities and features of a vehicle system can be selected and documented in order to streamline the business process of contracting out product development through the supply chain.

The selection of a manufacturing method for developing new products with optimal quality, minimal cost in the shortest time possible is a important phase of the industry. This paper uses artificial neural network to facilitate for product manufacturing method selection. Initially, general sorting is employed to select an initial product platform. Then using repertory grids method, designers contribute importance ratings to the design options. These ratings are employed to reduce the number of the derived design options, and thereby used as input data to a neural network. The neural network is then trained by using Levenberg-Marquart Algorithm in Mat lab software. The trained neural network is applied to classify the set of options into different patterns. The classification results can subsequently serve as base for the screening of preferred manufacturing options.

This article is intended to contribute to the development of proprietary technologies and the evaluation and selection of integrated technologies in the study of the aerospace concept necessary for the processes of technological appropriation. The problem addressed lies in the lack of modular platforms and lowcost test systems for experimental development and simulations of satellite systems. Therefore, compare to this the proposal of a scalable modular platform of the 1U CubeSat standard is presented as the main results. The design and characterization process presented from the concept of sustainability, contributes to the use and development of low-cost equipment that minimizes the impact on the environment and, in turn, is practical for its implementation in activities of groups and research centers that promote the diffusion of space technologies in Colombia. The methodology of sustainable design, the definition of design principles and conceptual design, which is materialized with the application of quality function deployment method (QFD), the theory of inventive problem solving (TRIZ)), the manufacturability-oriented design (DfM), assemblability (DfA), environmental impact (DfE), reliability (DfR), and safety assessment, are relevant for compliance with the CubeSat operating standards described in cds. Finally, several constructive modes of the low cost test platforms are proposed with different materials such as 3D prototyping in paper, abs, mdf wood and aluminum. All of them are small-scale satellite structures designed and constructed at low-cost. These designs result in the materialization to test on-board systems and integration resistance in assembly and materials, in laboratories as vibration test-bench, for research groups or companies interested in promoting the development of space technologies.

Traditional application of project risk management is limited to identifying and addressing project risks and then developing cost along with schedule contingencies. This paper proposes a method to consistently utilize the project risk management methods during Front End Engineering Design (FEED) phase of project development to select engineering design options. This method was called for recently to make several key engineering design decisions in a mega-project (case study). It allows significantly accelerate decision making and successfully manage various types of bias through leveraging the structure and visualization it provides. The proposed method is also applicable for engineering change management in any phase including operations.

This paper describes the design and testing of a novel hydraulic control valve for use in the minimally invasive surgical robotic manipulator. The use of hydraulics for surgical robotics opens new possibilities for miniaturization and robustness. However, to enable this, there exists a need for hydraulic components which bridge the size gap between traditional fluidics and microfluidics. This paper provides motivation for the development of a miniature hydraulic valve designed specifically to enable a serpentine style hydraulic surgical manipulator. Included are a description of the various considerations relevant to the valve and its specific application, such as the method of manipulation for the valve, as well as a theoretical valve design and a mathematical description of the operating principles. Two possible methods of valve activation, piezoelectric and electromagnetic, are discussed along with two physical realizations of the valve design are presented which demonstrate the theoretical design. Finally, the results of experimental testing performed on valve prototypes is described to evaluate the design options and help inform the selection of the final configuration.This is a preprint of an article submitted for consideration in ADVANCED ROBOTICS, copyright Taylor & Francis and Robotics Society of Japan; ADVANCED ROBOTICS is available online at http://www.tandfonline.com/tadr.
