Open- loop, Closed Loop & Systems Thinking
present a problem, question, or challenge in the copy, without immediately providing a solution, answer, or resolution.
open loop
waht is a COMPLEX SYSTEMS AND SYSTEMS FAILURE
A system is an arrangement (pattern, design) of parts which interact with each
other within the system's boundaries (form, structure, organization) to function
as a whole. The nature (purpose, operation) of the whole is always different
from, and more than, the sum of its unassembled collection of parts.
what is Criteria and Constraints
A designer or engineer is always
working within requirements, such
as criteria and constraints.
what is a Technology System
A technology system is a group of resources
(subsystems) working together to solve problems
and extend human capabilities.
what is a Development & Quality Control
One of the greatest benefits of learning about technology
is also learning to do technology, that is, to carry out in the
laboratory-classroom many of the processes that underlie the
development of technology in the real world.
whats the open loop defnshin
An open-loop system is a control system that has no means for
comparing the output
whats is the defensh and how does it help people
An example of a complex
system is a traffic control
system. If a traffic light fails
at a major intersection it can
snarl traffic and cause all
kinds of problems for
motorist. The police will
usually intervene and direct
traffic until the traffic
control experts can restore
the system to normal
operation.
what is the big lesen and how it help
Throughout the design
process, designers must
constantly compare the
solution to the criteria
and constraints of the
problem.
what is the core Technologies
The core technologies are the basic building blocks” from which all technology systems are created.
hoe and technology sometimes helps to improve
personal lives
by lessening threats such as disease,
toil, or ignorance.
Systems and Systems
Thinking
Knowledge of systems
is a path to a better understanding of how mother
nature and human nature work.
how is it like a test lite and how does it reallat
and hlep
The traffic light is a
component of a larger
complex traffic control
system. Parts of a
complex system can
fail without harm to the
entire system.
what quality a critera
designers must
constantly compare the
solution to the criteria
and constraints of the
problem.
how many Core Technologies are tere and name them
• Biotechnology
• Electrical
• Electronic
• Fluid
• Materials
• Mechanical
• Optical
• Structural
• Thermal
what is development of technology
is a human activity
Making life easier involves generating new products and systems through creativity and innovation.High Definition Television (HDTV)
what is a Systems and Systems
Thinking and why does it help stuff
A system is a group of interrelated
components designed collectively
to achieve a desired goal. Systems
can be open-loop or closed-loop.

From the
moment you flip the
first switch each
morning, you are
connecting to a huge
complex system
Example Design
For the given design challenge, what would be
the criteria and constraints?
what is a CHANGING” and how is it inpten
Stain “eating” enzymes in
detergent, bacteria “leaching” of
metals from ore, altering plant
genes to produce better crops
example, from the time
of the first gas cook stove in
1936
microwave oven in 1967,
the focus was on simplifying
the process of cooking and
reducing the time of food
preparation
how can a gool help you and go into the same as that
Technology is designed to reach a
desired goal. Most technology is
designed with several goals in
mind.
what is a COMPLEX SYSTEMS AND
SYSTEMS FAILURE
Complex systems have many layers of controls
and feedback loops to provide information. Controls
do not always succeed or work perfectly.
how can we fine the limit firm the strait
Identifying criteria and specifying constraints will provide the basis for what the design should be and what its limits are.
how is Electrical Technology inpront
Technology of producing, storing,
controlling, transmitting and getting work
from electrical energy
The sharing of the development and
production of an invention (a new product or
system) or innovation
xpands the knowledge base of technology. This new knowledge will have a direct effect on the ability of people to develop and produce more technologies which is referred to as technology transfer or spin-offs.
