The engineering design process is a methodical series of steps that engineers use in creating functional products and processes. The process is highly iterative - parts of the process often need to be repeated many times before another can be entered - though the part(s) that get iterated and the number of such cycles in any given project may vary.
It is a decision-making process (often iterative) in which the basic sciences, mathematics, and engineering sciences are applied to convert resources optimally to meet a stated objective.
10 Steps of Engineering Design Process are :
1) Identifying the problem.
2) Defining Working Criteria and Goals.
3) Researching and Gathering Data.
4) Brainstorming and Generating Creative Ideas.
5) Analyzing Potential Solutions.
6) Developing and Testing Models
7) Making the Decision.
8) Communicating and Specifying.
9) Implementing and Commercializing.
10) Post-Implementation Review and Assessment.

2_Analogy btw science math and engineering and ED.pptxaabhishekkushwaha9
An analogy between SMEs (Small and Medium Enterprises) and design could be drawn in various ways, highlighting similarities in their characteristics, processes, or importance. Here's one analogy:
Foundation and Flexibility:
SMEs are often likened to the building blocks of an economy, providing the foundation for growth and innovation. Similarly, design serves as the foundation for products, services, and experiences, shaping their functionality, usability, and aesthetics.
Just as SMEs need to be flexible and adaptable to changing market conditions, design also requires flexibility to meet evolving user needs, technological advancements, and design trends.
Problem-Solving Approach:
SMEs typically thrive by addressing niche markets, solving specific problems, or fulfilling unmet needs. Similarly, design is fundamentally about problem-solving, whether it's improving user experiences, optimizing efficiency, or enhancing aesthetics.
Both SMEs and design involve identifying challenges, brainstorming solutions, and implementing strategies to achieve desired outcomes.
Biomedical engineers design electrical circuits, software to run medical equipment, or computer simulations to test new drug therapies. In addition, they design and build artificial body parts, such as hip and knee joints. In some cases, they develop the materials needed to make the replacement body parts among others. The engineering design process is a methodical series of steps that engineers use in creating functional products and processes. The process is highly iterative - parts of the process often need to be repeated many times before another can be entered though the part(s) that get iterated and the number of such cycles in any given project may vary.

A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.
The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.
2. Problem Solution
Real – world problems are often unstructured and
open – ended
A problem may have multiple solutions
Each solution has many advantages and disadvantages
The preferred solution is that best meet the needs and
desires of an employer, a client, or the public.
3. The Nature of Engineering Design
• Engineering work often involves planning and analysis
in the initial stages, but the essence of engineering
problem solving is design.
• Engineering design is as varied as the engineering
profession and as board as the problems facing
humankind.
• Engineering design: is to conceive, imagine, devise and
plan a device, a structure, a process, or a system that
will benefit people.
4. Team Work
• Design of large projects needs to be carried out by
many engineering teams of different engineering
specialists.
• Team work: “is the work done by several associates
with each doing a part, but all subordinating personal
prominence to the efficiency of the whole ’’
• Team work can lead to better decisions, products, or
services.
• A disadvantage of the team work is the “social loafing”
i.e. an individual’s doing less work than what he
would normally do working individually.
5. Engineering Design Phases
1- Identification of the problem.
2- Gathering needed information.
3- Searching for creative solutions.
4- Stepping from ideation to preliminary designs.
5- Evaluation and selecting of preferred solution.
6- Preparation of the reports, plans, and specifications.
7- Implementation of the design.
6. 1 - Identification of the Problem
• An incorrect definition of the problem will make the
engineer to waste time and may lead to inappropriate
solution.
• It is important that the stated needs be real needs
• If it is a product that is being designed, a preliminary
market analysis will be essential
• The problem shouldn’t be unnecessary constrained
• If too many constraints are placed on the problem, this may
cause its solution extremely difficult or impossible
7. 2 – Gathering Needed Data
• Data or information will depend on the type of the
problem to be solved
• Data could be physical measurements, maps, results of
laboratory experiments, patents, results of opinion
surveys
• Engineers shall undertaken literature search to learn
what others have learned about related problems
8. Engineers may visit technical libraries, study text
books, journal articles, and manufacturer‘s catalogs
If the engineer is employed by a large corporation or a
public agency, it will be useful to search old files and
interview other colleagues who dealt with similar
problems
9. 3- Searching for Creative Solutions
Several operational techniques can be used to help a
group to produce original ideas:
- Brainstorming:
- group of usually 6-12 people who introduce ideas to
solve a specific problem
- They generate as many ideas as possible
- They may combine or improve on ideas of others
-Brainstorming sessions usually last not longer than
one hour.
10. - Checklists:
Checklists include various points of design
possibilities. For example if it is supposed to
improve a certain device the checklist may include (
ways the device could be rearranged, ways the device
could be magnified, ways the device could be put to
other uses, . . )
- Attribute Listing:
List all attributes of product / object: Ex: Color,
Material, Size, Weight, . . .
Think of all ideas to improve each attribute separately
11. 4 - Stepping From Ideation To Preliminary
Designs
This is the heart of the design process.
Possible solutions and ideas to be carefully evaluated.
Engineers often rely on models to facilitate the design
process.
The model is “ any simplified description of an
engineering system or process that can be used in the
analysis or design “
12. Three types of models:
a - Analytical or mathematical models
A mathematical model consists of one or group of
equations that represent a physical system.
EX: = k h
Where : = lateral earth pressure
= soil weight
h = height of soil
13. b – Simulation Models
When studying complex systems, engineers use
computer simulation models ( 2D or 3D )
c – Physical Models
Have been used for many years in the fields of
structure design, hydraulics, hydrodynamics,
aerodynamics
14. 5- Evaluation and Selection of Preferred
Solution
Feedback, modifications, and evaluation may occur
repetitively as the device or system evolves from
concept to final design.
If we deal with a product : safety, cost, reliability, and
consumer acceptability are of paramount importance.
Economic studies can be used to: (determine the
feasibility of a project, compare alternate designs,
priority of construction of a group of projects )
15. 6- Preparation of Reports, Plans, and
Specifications
The final design must be presented ( to those who
must approve it ), in the form of an engineering report
, a set of plans and specifications.
7- Implementation of the Design
To the design engineer , it is the most satisfying phase
of all
16. Learning From Failures
Engineering failures may be attributed to:
1- Mistakes made by careless designers.
2- Imperfections in building or manufacturing materials.
3- Careless workmanship by technicians or craftsmen
who implement the design.
4- Poor communications between the managers,
engineers, technicians, and craftsmen who produce or
construct the design.
17. Case Study
Kansas in 1981: Two walkways in Hyatt Regency Hotel
collapsed. 114 people killed and 185 injured.
A connection detail was changed at the site by the
contractor without consulting the designer.
