Understanding Electrical Engineering with Analogie

the role of analogies in the engineering design process, and educational applications for analogical reasoning. Researchers have discovered that analogical reasoning is often a fundamental cognitive tool in design problem solving. Regarding the possible role of analogical reasoning in the context o water starts flowing from a collector (battery) Nothing in an electric circuit really works like a collector of water. In your analogy, water is electric charge which, in metals, is carried by electrons slowly drifting. Batteries do not store charge, they are not a reservoir of charge (nor of electrons) Analogies give engineers insight. A person trying to explain a difficult concept will often say, Well, the analogy is . The use of analogies in everyday life aids in understanding and makes everyone better communicators. Mechatronic systems depend on the interactions among mechanical, electrical, magnetic, fluid, thermal, and. the generation of concepts in engineering and architectural design, an important research question is: Can a Design-by-Analogy approach, in particular, a word-based ideation method, provide transactional domain experts the ability to increase quantity, novelty and quality whil

One way is to construct an analogy between two systems. Each common feature leads to an abstraction; each abstraction connects our knowledge in one system to our knowledge in the other system. One piece of knowledge does double duty. Like a mental lever, analogy and, more generally, abstraction are intelligence amplifiers engineering design: The process of devising a system, component or process to meet desired needs.

Combines an understanding of basic sciences, mathematics and engineering sciences to use available resources. engineering analogy engineering psychology marine engineering engineering analogy response by analogy principle hydraulic engineering civil engineering electrical engineering analogy test public health engineering electronic and communication engineering engineering material structural engineering aeronautical engineering engineering drawing. The analogy method is most appropriate early in the program life cycle when the system is not yet fully defined. This assumes there are analogous systems available for comparative evaluation. As systems begin to be more defined (such as when the program enters the Engineering and Manufacturing Development Phase (EMD)), estimators are able to. In terms of thinking like humans, analogies are where it's at, said Forbus, Walter P. Murphy Professor of Electrical Engineering and Computer Science in Northwestern's M c Cormick School of Engineering. Humans use relational statements fluidly to describe things, solve problems, indicate causality, and weigh moral dilemmas

Engineering principles taught well to students become the foundation for lifelong understanding of physical processes. No set of engineering principles is more useful or pervasive than the concepts of effort variables and flow variables. By analogy, these can be applied to almost an Reasoning by analogy is a great way to help persuade, explain, and understand new ideas or concepts. The use of analogies in law is done through appeal to precedent, where old cases are applied to. Analogous Estimation uses a similar past project information to estimate the duration or cost of your current project, hence the word, analogy. You can use analogous estimation when there is limited information regarding your current project. Quite often, there will be situations when project managers will be asked to give cost and duration estimates for a new project as the executives need.

Geotechnical engineers frequently use design-by-analogy methods to promote innovative design solutions, or reuse existing design schemes. However, this approach has not yet provided a means for comparing various potential project solutions quantitatively. Moreover, while geotechnical engineering has accumulated data in large. Estimating by analogy is a top down method that relies on their being previous projects with very similar attributes to the one you are about to begin. This is a technique for early life cycle macro-estimations. Actual data from completed projects is extrapolated to provide estimates for the proposed project analogy. It is a technique widely applied by innovators. Traditionally, analogous solutions are sourced from other industries, but a recent trend has practitioners of design by analogy looking to a more distant domain for solutions—biology. Design by analogy to biology, often called biomimicry,1 is innovatio

  1. If I did not use analogies to explain things, but actually used the detailed theory of the application of engineering and physics, there would be negative consequences. For one thing, I wouldn't be able to do it. I feel that I have a pretty good understanding of the techniques that we use, but only at a superficial level
