Creative design lies at the intersection of novelty and technical feasibility. These objectives can be achieved through cycles of divergence (idea generation) and convergence (idea evaluation) in conceptual design. The focus of this thesis is on the latter aspect. The evaluation may involve any aspect of technical feasibility and may be desired at component, sub-system or full system level. Two issues that are considered in this work are: 1. Information about design ideas is incomplete, informal and sketchy 2. Designers often work at multiple levels; different aspects or subsystems may be at different levels of abstraction Thus, high fidelity analysis …

In today’s day and age, the use of automated technology is becoming increasingly prevalent. Throughout the aerospace industry, we see the use of automated systems in manufacturing, testing, and, progressively, in design. This thesis focuses on the idea of automated structural design that can be directly coupled with parametric Computer-Aided Drafting (CAD) and used to support aircraft conceptual design. This idea has been around for many years; however, with the advancement of CAD technology, it is becoming more realistic. Having the ability to input design parameters, analyze the structure, and produce a basic CAD model not only saves time in …

This report provides an overview of scramjet-powered hypersonic vehicle modeling and control challenges. Such vehicles are characterized by unstable non-minimum phase dynamics with significant coupling and low thrust margins. Recent trends in hypersonic vehicle research are summarized. To illustrate control relevant design issues and tradeoffs, a generic nonlinear 3DOF longitudinal dynamics model capturing aero-elastic-propulsive interactions for wedge-shaped vehicle is used. Limitations of the model are discussed and numerous modifications have been made to address control relevant needs. Two different baseline configurations are examined over a two-stage to orbit ascent trajectory. The report highlights how vehicle level-flight static (trim) and dynamic …

The goal of this research was to contribute to the understanding of how the physical design of Intensive Care Unit (ICU) environments may be improved to enhance nursing communication, and in turn, the quality and safety of patient outcomes. This study was guided by two research questions: (1) What are the major characteristics of nurse communication in a hybrid ICU nurse station design? (2) What are the factors in the built environment that enhance or hinder nurse communication in a hybrid ICU nurse station design? The research design was exploratory and qualitative. Observations were conducted in two ICUs with hybrid …

In response to the rapid rise of emerging markets, shorter product lifecycles, increasing global exchange and worldwide competition, companies are implementing `sustainable development' as a mechanism by which to maintain competitive global advantage. Sustainable product development approaches used in industry focus mainly on environmental issues, and to a certain extent on social and economic aspects. Unfortunately, companies have often ignored or are unsure of how to deal with the cultural dimensions of sustainable product development. Multi-nationals expanding their business across international boundaries are agents of cultural change and should be cognizant of the impact their products have on local markets. …

Communication networks, both wired and wireless, are expected to have a certain level of fault-tolerance capability.These networks are also expected to ensure a graceful degradation in performance when some of the network components fail. Traditional studies on fault tolerance in communication networks, for the most part, make no assumptions regarding the location of node/link faults, i.e., the faulty nodes and links may be close to each other or far from each other. However, in many real life scenarios, there exists a strong spatial correlation among the faulty nodes and links. Such failures are often encountered in disaster situations, e.g., natural …

In this work, different passive prosthetic ankles are studied. It is observed that complicated designs increase the cost of production, but simple designs have limited functionality. A new design for a passive prosthetic ankle is presented that is simple to manufacture while having superior functionality. This prosthetic ankle design has two springs: one mimicking Achilles tendon and the other mimicking Anterior-Tibialis tendon. The dynamics of the prosthetic ankle is discussed and simulated using Working model 2D. The simulation results are used to optimize the springs stiffness. Two experiments are conducted using the developed ankle to verify the simulation It is …

Digital Fabrication has played a pivotal role in providing reality to industrial designers' ideas since its first commercial use in late 80's. Making the final prototype of a design project has been the initial assumed use for these technologies in the design process. However, new technology advances in this area offer further opportunities for designers. In this research these opportunities have been carefully explored. This research will be conceptualized through discussing the findings of a case study and theories in the areas of Industrial Design methodology, digital fabrication, and design pedagogy. Considering the span of digital fabrication capabilities, this research …

The Autonomous Vehicle (AV), also known as self-driving car, promises to be a game changer for the transportation industry. This technology is predicted to drastically reduce the number of traffic fatalities due to human error [21]. However, road driving at any reasonable speed involves some risks. Therefore, even with high-tech AV algorithms and sophisticated sensors, there may be unavoidable crashes due to imperfection of the AV systems, or unexpected encounters with wildlife, children and pedestrians. Whenever there is a risk involved, there is the need for an ethical decision to be made [33]. While ethical and moral decision-making in humans …

All too often, industrial designers face seemingly intractable obstacles as they endeavor to, as Simon (1996, p. 111) describes, devise "courses of action aimed at changing existing situations into preferred ones." These problems, described by Rittel and Webber (1973) as "wicked," are insurmountable due to the contradictory and changing nature of their requirements. I argue that that industrial design (ID) is largely subject to Rittel's quandary because of its penchant for producing single solutions for large populations; such design solutions are bound, in some senses, to fail due to the contradictory and changing nature of large and, thus, inherently diverse …
