Multiobjective optimization is rapidly becoming an invaluable tool in engineering design. A particular class of solutions to the multiobjective problem said belong Pareto frontier. solution, set which comprises frontier, optimal sense that any improvement one design objective can only occur with worsening at least other. Accordingly, frontier plays important role design—it characterizes tradeoffs between conflicting objectives. Some methods be used automatically generate a from final...
Multiobjective optimization is a powerful tool for resolving conflicting objectives in engineering design and numerous other fields. One general approach to solving multiobjective problems involves generating set of Pareto optimal solutions, followed by selecting the most attractive solution from this as final design. The success critically depends on designer's ability obtain, manage, interpret set—importantly, size distribution set. potentially significant difficulties associated with...
We introduce the notion of s-Pareto optimality and show how it can be used to improve concept selection in engineering design. Specie c design alternatives are classie ed as optimal when there no other from same or any general that exhibit improvement all objectives. Further, we say set comprises frontier. Under proposed approach frontier plays a paramount role process, is dee ne classify dominance. Thes-Pareto frontier-based method becharacterized onethat capitalizes on benee ts...
This paper reviews the findings of several engineering researchers and practitioners on topic design for developing world. We arrange these into nine guiding principles aimed at helping those who are searching effective approaches The reviewed come from mechanical discipline, as well other nonengineering disciplines. For each principle, we provide references to various studies a means supporting principle. also detailed example Based our own experience based many papers reviewed, succinct...
Engineers face many challenges when designing for the developing world, which are not typically encountered in other design circumstances, such as a lack of understanding language, culture, and context. These often prevent engineers from having sustained impact they resource-poor individuals. In this paper, reports 41 engineering projects world were analyzed, common pitfalls identified. The data came Failure Reports Without Borders (EWB) Canada authors' own field reports. After described,...
This study set out to identify emerging trends in advancing engineering for sustainable development, supporting the workforce address wicked problems, and strengthening pathways between education, industry, policy. The following question guided this work: What are factors impacting future of global sustainability efforts within engineering, how can these be amplified increase impact development? Using an adapted Delphi method with surveys, focus groups, member-checking interviews, we hosted...
An important factor in system longevity is service-phase evolvability, which defined as the ability of a to physically transform from one configuration more desirable while service. These transformations may or not be known during design process, and reversible. In different study, we examined 210 engineered systems found that excess modularity allow evolve Building on this observation, present paper introduces mathematical relationships map system's evolve. As introduced paper, relationship...
Over the past decade a large amount of research has been dedicated in academic literature to improving technical capabilities improved cookstoves; primarily performance efficiency and reduction emissions. Unfortunately, as published highlighted, trade-offs that result from placing such concentrated emphasis on these objectives is cookstoves lack same level usability traditional cookstoves. Thus, users often return using their stoves potential impact never fully realized. In order for have...
Abstract Organizations all over the world, both national and international, gather demographic data so that progress of nations peoples can be tracked. This is often made available to public in form aggregated level or individual responses (microdata). Product designers likewise conduct surveys better understand their customer create personas. Personas are archetypes individuals who will use, maintain, sell otherwise affected by products created designers. help person product designed for....
System models help designers predict actual system output. Generally, variation in inputs creates outputs. Designers often propagate variance through a model by taking derivative-based weighted sum of each input’s variance. This method is based on Taylor-series expansion. Having an output mean and variance, typically assume the outputs are Gaussian. paper demonstrates that rarely Gaussian for nonlinear functions, even with inputs. also presents solution to more meaningfully describe...
Sustainable design is often practiced and assessed through the consideration of three essential areas: economic sustainability, environmental social sustainability. For even simplest products, complexities these areas their tradeoffs cause decision-making transparency to be lost in most practical situations. The existing field multiobjective optimization offers a natural framework define explore given space. In this paper, method for defining product’s sustainability space (defined by...
Analysis and synthesis of compliant mechanisms has recently been the subject significant study in research community. This focus led to a number design approaches for developing mechanisms. paper describes value using Pseudo-Rigid-Body Model (PRBM) commercial products. Application PRBM is illustrated through development two parallel mechanisms: bicycle derailleur parallel-motion brakes. The allows be modeled analyzed as rigid-body significantly reduces complexity analysis. Mechanisms with...
The recent introduction and advancements in design of simple, constant-force mechanisms have created the potential for small-scale, low-cost, electronic connectors (CFECs). CFECs differ from traditional by separation or disassociation contact normal force deflection. By removing constraints imposed forces deflections that are dependent on each other, new types can be explored. These designs may lead to smaller more reliable connectors. In this paper, adapted satisfy current industry...
The dramatic and often unjust difference between life in the developed versus developing parts of world is striking. For example, roughly 3 billion people still burn biomass to cook their meals; more have a mobile phone than toilet; Dallas Cowboy Stadium (AT&T stadium) requires three times electrical power entire country Liberia can produce; 73 s shower (using an EPA approved low-flow head) uses all daily clean water available per person Rwanda. These conditions others given rise interesting...
One of the purposes creating products for developing countries is to improve consumer's quality life. Currently, there no standard method measuring social impact these types products. As a result, engineers have used their own metrics, if at all. Some common metrics include sold and revenue, which measure financial success product without recognizing successes or failures it might have. In this paper, we introduce potential universal metric, metric (PIM), quantifies has on impoverished...
Flapping flight has the potential to revolutionize micro air vehicles (MAVs) due increased aerodynamic performance, improved maneuverability, and hover capabilities. This paper presents design of a robotic flapping wing mechanism for use in general studies involving laboratory-based experimental optimization trajectories. The allows dynamic adjustment trajectories or liquids with three rotational degrees freedom on each wing. design, instrumentation, control are discussed, characterization...
University engineering programs across the USA engage in service learning projects. These projects involve student teams designing and implementing products or solutions for communities need, often developing nations. There has been much research done relating to pedagogy impact of these on learning. However, less measuring affected communities. This paper examines factors that practitioners believe are related successfully delivering a desirable transferable solution The authors identified...
