The 10 LEVERS OF ‘smart engineering’
‘Smart
engineering’is all about using insights to conceive,model and scale an
appropriate solution to a problem or an objective.Scientific,
economic,social,and practical knowledge is applied in the process.This
knowledge serves as an engine behind designing,building and maintaining
structures,machines,systems, materials and even processes.
1 NEED-OF-THE-HOUR ENGINEERING: IN THE BEFORE CHRIST PERIOD,
people focused on primitive technology for agriculture - studying
soil characterisation,improving irrigation system,and finding means of
ploughing land for harvesting.As civilisation moved from the Stone Age
to the Metal Age,the society learnt to cook and prepare food.Agriculture
to heavy engineering to electronics engineering - various themes have
got emphasis during India’s series of five-year plans.Today’s
‘need-of-the hour engineering’ is towards a wide deployment of broadband
and connectivity, and an optimisation of required infrastructure.
2 IMPROVISED ENGINEERING: I
CALL the second lever of smart engineering as ‘improvised engineering’.
This deals with how the same or similar purpose is achieved by more
sophisticated technology.For example, in the early days,the shadow from
an anchored stick used to give relative time-of-the-day.Currently,we
have watches of all types including highprecision instruments that
capture the split-second difference between winner and runner-ups in the
Olympics 100-meter race.Smartphones have not only enriched voice
communication,but also eased filesharing and multimedia data transfer.
3 STRIP-DOWN ENGINEERING: CURIOSITY
about what goes into a product design gets satiated to a great extent
by reverse engineering. How many people have tried to unravel Coke’s
signature formula? We also hear about frugal engineering, which drives
down the cost factor but at times fails to maintain the durability of
the product.‘Strip-down engineering’combines the strengths of reverse
engineering and frugal engineering.The engineering smartness here is
built around applying Pareto’s 80:20 principle and analysing how to keep
essential functionalities.The goal is to select the top 80 per cent
features from a user perspective and implement them with 80 per cent
cost reduction.
4 PERFORMANCEBOOSTING ENGINEERING: THE
SUCCESS of a product or service lies in its performance by relative as
well as absolute measures.‘Performance-boosting engineering’seeks to
enhance performance by keeping constraints in mind.Let us take the
example of the mobile phone where we currently leverage the octa-core
processor.The evolution from single-core to octa-core has enabled us to incorporate parallelisation and increase processing power.In a heterogeneous
processing environment, appropriate partitioning of code across
ASIC,DSP,CPU,GPU,and MCU chips significantly drive up system
performance.This category of smart engineering also encompasses
developing multi-resolution systems,such as a spectrum of products from
phone-with-full-connectivity-but-basic-camera to
higher-resolution-camera-but-basic-phone-connectivity. This class of
smart engineering facilitates introduction of more complex
features,reduces response time or boosts other system performance
metrics.
5 INTELLISYS ENGINEERING: ‘INTELLISYS
ENGINEERING’empowers intelligent systems,promotes autonomous operation
based on closedloop control,energy efficiency and networking
capabilities for a platform or a system to be intelligent.IntelliSys
engineering for connected cars enables us to build cars that aid in
navigation,cars that can go driverless,cars that talk to each other by
wi-fi technology and cars that will even fly!
6 CROSSPOLLINATION ENGINEERING: STUDYING a single field dries up one’s ideas! Newer fields are emerging.And solutions for some problems require extensive knowledge of multiple faculties - either to tie ideas up,or learn from one field and apply to another.This is what
I term as ‘cross-pollination engineering’.For example,knowledge of
geology and soil engineering combined with biology helps to address
problems pertaining to geo-microbiology.This helps us understand how
bacteria and viruses come to our food through soil contamination and
what possible remedies could be taken up. Geography knowledge in
conjunction with information system expertise paves the way for
Geo-Information System (GIS).Cross-pollination engineering
gives birth to new fields like fiber optic communication that combines
optical physics with telecommunication.The field of music,coupled with
acoustics engineering,opens a chapter of musicology by cross-pollination
of subtleties in both fields.
7 SMART-AUXILIARY ENGINEERING: AT
TIMES, engineering plays second fiddle to scientific projects - it
helps in next-level of scientific discoveries through infrastructural
support.Let us consider the lLarge hadron collider mega project recently
conducted in CERN,Geneva.The very simulation of the Big Bang has been
an engineering feat - this has been a pre-requisite to determine what
happens after the big bang event.The support role of engineering should
not be misconstrued as engineering trivia.One mouse can bother an
elephant! One bird can hit a plane and knock it down.
8 SUSTAINABLE ENGINEERING: ‘SUSTAINABLE
engineering’encourages us to build products that consume less energy
and cause least damage to the environment.Let us take the example of
electronic circuitry.Researchers have progressed to operate digital
chipsets in 1.8V instead of 3V or 5V.Energy-aware protocols have also
been designed.These techniques substantially help in overall power
reduction for electronics equipments. Sustainable engineering addresses
concerns around energy consumption,electro-magnetic radiation hazards
produced by cell towers and so on.How to reduce contamination and even
re-purify natural resources for our well-being is the concept behind
sustainable engineering that impacts the product design phase.
9 NATURE-INSPIRED ENGINEERING: CITY
parks often have bushes that are shaped like animals.We can also design
usable products inspired by flora and fauna.Cranes are built mimicking a
long-necked giraffe.Look at our national flower lotus.The lotus leaves
manage to remain free of contaminants as they possess a field of small
bumps and dust is easily picked up by water drops.Nature-inspired
engineers study objects and phenomena from nature to understand how a
fundamental scientific principle works in daily life and apply the
notions in product design.
10 FORWARD-LOOKING ENGINEERING:
ENGINEERING
foundations that are based on strong theory and driven by science can
be quite forward-looking. Information theory,game theory, number theory
and string theory have all been playing roles in
telecommunication,cryptography and other associated areas.Technology is
moving from virtual reality to augmented reality.User interactions are
changing from touch-base to gesture-controlled.Integration of audio,
visual and haptic feedback is becoming a part of next user interaction.
Quantum computing uses qubits with superposition and entanglement.Using
these basic principles, quantum teleportation allows the same entity to
be in two places simultaneously,but observation decoheres.
Forward-looking engineering aims to manifest scientific ideas or even
science fiction concepts to reality.

undergraduates should not be charged fees. They should receive grants
not student loans, and the government will get the money back long-term
from increased exports.
