Technology is the branch of knowledge
which deals with the conversion of raw
materials into articles, product of utility.
This requires knowledge about :-
Materials,Methods,Tools and Equipments.
Design is using technology but it is not only technology!
What is Design?

Engineering is the application of mathematics, empirical evidence and scientific,
economic, social, and practical knowledge in order to invent, innovate, design, build,
maintain, research, and improve structures, machines, tools, systems, components,
materials, and processes. (Or) Arts and science of utilizing the forces and materials of
nature for the benefit of mankind and for the direction of man’s activities towards this
end.

What is Design? - 'Ninth Symphony’ by Beethoven

What is Design? - 'Starry Night' by van Gogh

 In science, if you don't do it, somebody else will. Whereas in
art, if Beethoven didn't compose the 'Ninth Symphony,' no one
else before or after is going to compose the 'Ninth Symphony'
that he composed; no one else is going to paint 'Starry Night'
by van Gogh. Neil de Grasse Tyson

What is Design ?

 Design challenges are not limited to engineering, but can also be
found in other fields.
 Artists, architects, interior designers, clothing designers, etc., are all
“designing” products and solutions for us! So, they are also engaged
in the design process!
 So, what is design? Design can be loosely stated as the art of creating
something that does not exist. Such a creation can be in the mind,
too. For instance, you can “design a story” by thinking about the story
plot, the characters you want to use in the tale, how long you want it
to be, and who you want to be reading it.

 Decision-making
 Modeling
Design Activity

Purpose of Design

The purpose of design is defined [Mostow, 1985] as the
construction of a structure (artifact) description that;
 Satisfies a given (probably informal) functional
specification,
 Conforms to the limitations of the target medium,
 Meets implicit or explicit requirements on performance (time,
space, power, cost etc.) and structure (style, simplicity etc.),
 Satisfies restrictions on the design process itself.
Purpose of Design

Engineering – Left Brain / Design – Right Brain

Design Engineering / Engineering Design

 There has always been confusions among people between
Industrial / Engineering design (ID/ED) and Design
engineering.
 And the same confusion applies to art school and design
school which the lines are often blurred.
 These two categories of design have a fundamental difference
between them:
 ID / ED is an applied art, whereas
 DE is a discipline

Discipline or applied art?... … …
 What is discipline? Merriam-Webster defines discipline as “a
field of study” and as “a rule or system of rules Governing
Conduct or activity”.
 What is Applied Arts? Is the conscious use of one or more
technique (from the Greek: téchnē which means art) to a
definite field intended to go beyond the aesthetic expression
of the human spirit.

 Industrial Design / Engineering Design is more than applied art.
 ID / ED is responsible for the functional, structural, ergonomic,
environmental, operational, productive and economic aspects of
products which today integrate the human artificial eco-system or
“world of objects”.
 ICSID (International Council of Societies of Industrial Design)
says that “The design is a creative activity which has a purpose of
determining the formal qualities of the products items. By formal quality,
we shouldn’t understand only the external qualities, but mainly the
structural and functional relationships that are the centre of a
coherent unity”.

In other words, the ID/ED is a discipline that is concerned in the
integral aspects of products and not just cosmetics.
In the other hand, Design Engineering is a field of action.
 DE is, the way a see it, a field whereby engineering practices
(as well as science and arts concepts) are applied by engineers
(and Industrial Designers as well) to create, develop and
maintain products.

Industrial / Engineering designers must understand a few things
which are very important:
1. Creativity comes from discipline (not from dreams).
2. We Design to satisfy needs (what the customer needs / wants).
3. We design to work (if it doesn’t work, then it is a crap). Anything can be
achieved on paper, but everything that has been designed must work.
4. We Design to be manufacturable (if it can’t be produced… then it was
not well designed). This implies knowledge and definition of technologies,
processes, materials, etc.
5. We Design for the real world (dream is for free… but the design process
is about money).

Engineering and design activities are blended in Engineering

Product Design & Development – Products

Product refers to a PHYSICAL PRODUCTS or SERVICE or an
IDEA which a CUSTOMER or CONSUMER NEEDS and for
which he is READY TO PAY.
PHYSICAL PRODUCTS include tangential goods like grocery
items, garments to name a few…
Introduction – Products

SERVICES are INTANGIBLE PRODUCTS which are offered
and purchased by consumers. Services may also include an
innovative idea on any aspect of operation.

benefits

A consumer may purchase a product to get three types of
benefits – FUNCTIONAL, PSYCHOLOGICAL & SOCIAL
BENEFITS.
For example, the purchase of a motor cycle provides functional
utility of a transportation, but at the same time satisfy the need
for prestige and esteem and provides social benefit by the way of
acceptance from a group, by riding the motor bike.
Thus all those aspects should be considered while planning for a
product

Introduction – Consumer & Industrial Products

Consumer Product

Products that are purchased by the ultimate consumers for their
personal consumption are called CONSUMER PRODUCTS.
For example SOAPS, EDIBLE OIL, EATABLES, TEXTILES,
just to name a few.

CONVENIENCE PRODUCTS are those products which are
PURCHASED FREQUENTLY, without much planning or shopping
effort and are consumed quickly. Example of such products are
cigarettes, Ice-creams, medicines, new papers, tooth paste and so
on. These products have low unit value and are bought in small
quantities.

Shopping Products

The products which are purchased less frequently and are used
very slowly are SHOPPING PRODUCTS. In case of these
products, consumers devote CONSIDERABLE TIME &
EFFORTS to compare the quality, price, style and suitability of
these products at certain stores.
Some of the examples of shopping products are cloths, shoes,
furniture, radio to name a few.

SPECIALITY PRODUCTS are those products which have
certain characteristics because of which customer make special
efforts in their purchase. Customers willing to PAY HIGHER
PRICES and also put up EXTRA TIME to locate the seller to
make the purchase.
Examples of speciality products are a rare collection of artwork
or of antique, jewelry, wedding dresses, cars and so on. The
demand for these goods is relatively inelastic that is the demand
does not fall even at the higher prices.

NON-DURABLE PRODUCTS are those consumer products
which are normally consumed in one or few uses. Examples of
such products are soap, salt, pickles, sauce and so on.
Such items are made available by producers through large
number of convenient retail outlets. Profit margins on such
items are usually kept low and heavy advertising is done to
attract people towards their trial and use.

These products are generally used for a longer period and
command a higher per unit margin, require greater
personal - selling efforts, guarantees and after sale
services on part of the seller.

termed as INDUSTRIAL PRODUCTS if it is used for manufacturing
bath soap.
Consumer & Industrial Products

The ways these products are marketed to these two groups are very
different because purchase by industrial buyer is usually large in quantity
and bought either directly from the manufacturer or from local distributor.

Raw Materials – Farm Products

RAW MATERIALS falls into two groups: FARM PRODUCTS &
NATURAL PRODUCTS.
FARM PRODUCTS like cotton, sugar cane, oil seeds and so on are
supplied by many producers. These producers send these goods to
marketing intermediary for assembling, grading, storage, transportation and
selling services.
FARM PRODUCTS require special marketing practices due to their
perishable and seasonal nature. Their commodity character results in
relatively little advertising and promotional activities with some exceptions.
Raw Materials – Farm Products

Raw Materials – Natural Products

NATURAL PRODUCTS such as minerals, fish, lumber and
so forth are limited in supply, usually have great bulk and low unit
value. There are fewer and larger producers who often market
them directly to industrial users.
In the case of these products, long term supply contract are
common, as the users depend on these materials. The
homogeneity of the natural materials limits the amount of demand
creation activity, Price and Delivery reliability are the major
factors influencing the selection of suppliers.

Installations Equipments
Capital Items - Installations

INSTALLATIONS consist of building (factories & offices) and
heavy equipment (generators, drill presses, mainframe
computers, elevators Etc.).
INSTALLATIONS are usually bought directly from the
producers with the typical sale preceded by a long negotiation
period.

Capital
Items
Installations Equipments
Capital Items - Equipments

EQUIPMENTS comprise portable factory equipment and tools
(hand tools, lift trucks etc.) and office equipment (personal
computers, desks etc.)
EQUIPMENTS do not become part of finished products. They have
a shorter life than installations but a longer life than operating supplies.
EQUIPMENTS manufacturers sell these products directly more
often they use intermediaries because the market is geographically
dispersed, buyers are numerous and the orders are small.

The balancing factor to globalization is that products must be
customized to meet the needs of local markets, whether it’s for
language,climate, culture or price.
To achieve mass customization, the product has to be
configurable enough to meet the needs while standard enough to
be scalable. Compiled & Edited by SIVARAMAN VELMURUGAN 3383/12/2016

Localization & Mass Customization

Trends that will impact - Digitization

Digitization
Companies will increasingly rely on one true digital
representation of the product.
That digital representation will include not just the geometry and
Bill of Materials, but also the approved vendors, materials in each
component, regulatory approvals, manufacturing processes and
service requirements. Expect PLM to get bigger.

Trends that will impact - Regulation

Regulation
Product regulation adds another layer of complexity to
localization, since regulations vary by jurisdiction.
For example, many jurisdictions limit the amount and source of
certain materials that a product can contain.
Tracking those materials through the supply chain and then
reporting on them to the regulatory authorities is a complex
product management task that demands a sophisticated PLM
system.

Trends that will impact – Smart Products

Smart products
Mechanical products aren’t just mechanical anymore – they are
electronic and software products as well.
Even simple home appliances have lots of computing power, and
this trend isn’t going away.
This trend forces interdisciplinary teams and cross-functional
product development.
For example, Tier 1 automotive supplier Continental reportedly
has more software developers than mechanical engineers.

Trends that will impact – Connectivity

Connectivity
We’ve all heard of the Internet of Things.
One opportunity that connected devices will create for product
designers and support teams is the ability to remotely diagnose
and service products in the field.
That remote monitoring and serviceability in turn creates
business models that don’t transfer ownership, which brings us to
the next big trend….

Trends that will impact – Servitization

Servitization
Now there’s a word that’s not likely to catch on, but hey, we still say
“interoperability”, so who knows.
In this definition, servitization represents a change in design thinking away from
the physical manifestation of the product and towards conveying the benefits of
the product to the end user.
Instead of buying a truck, for example, a customer can buy the miles that the
truck will travel while the manufacturer retains the risks of ownership.
For this to work, product developers need to integrate service lifecycle planning
into their designs from the earliest concept stages.

Technologies that will blow you away

Air Propulsion

We sure love the idea of making a car’s internal combustion engine a bit more
efficient. In fact, many attempts have been made to advance the technology and
make EVs consume less.
Recently, Cadillac has been focusing a lot of air propulsion, and they have already
revealed Cadillac Aera. The concept won the Auto Show Design Challenge in L.A;
the magnificent style of the vehicle led to a hypothetical number of 1,000 miles on
compressed air prior to the refueling process.
Although there’s nothing wrong with today’s spectacular CTS-Vs, we would love to
get behind the wheel of a Cadillac Aera. For this to happen, we may have to wait
another 20 years.

Interchangeable Carbon Fibre Car Body Panels

Another smart technology that will knock your socks off comes from the
runner up of the Auto Show Design Challenge in L.A, the concept car
known as Smart 454WWT (aka weight watch technology).
Even though carbon fibre is not something new, Smart’s aim is to make it
more affordable.
The company’s concept vehicle has interchangeable body panels that are
supposed to reconfigure the vehicle based on the preferences of the driver.
The technology has great chances of materializing if Smart manages to
surpass crash testing.

In-Wheel Magnetic Drive Systems

Experts agree that tomorrow’s electric car will have more than one motor. Rumor has
it that there will be one motor attached to each car wheel.
Jaguar’s concept vehicle, the C-X75, already has this feature. However, Nissan’s iV is
even better if we look beyond the ivy composite and spider silk body.
Nissan has a patent for the technology, and apparently it can also handle suspension
duties and steering. We cannot expect for the automaker to make the magnetic drive
system a reality.
According to Nissan, the technology has great chances of becoming plausible by 2035.
That’s a lot of waiting time, but we’re sure that we won’t be disappointed when it
comes out.

Body PanelsThat Produce Energy

The auto industry is packed with peculiar, pairing and odd combinations
that somehow have great potential and seem to work pretty well. Toyota
strongly believes that, and therefore they’re developed Nori, which means
seaweed in Japanese.
For the making of this smart car technology, Toyota has created a carbon
fibre chassis/body, but they’ve added seaweed in the mix. They’re also
implemented solar panels to make the concept car energy-efficient.
The combined chassis and body is unbelievably light and strong. By adding
soar cells the vehicle generates supplemental power.

Pure Oxygen Emissions

We would love to breathe fresher air and not have to inhale polluted air
from all the cars on the streets. Sadly, that’s not possible just yet.
An upcoming smart car technology comes from Mercedes Biome, and it’s
really cool to say the least. It doesn’t have any nasty emissions and it aims at
creating pure oxygen emissions.
Can you believe that by 2050 the car we will drive might emit pure oxygen?
There’s nothing wrong with hoping that someday the technology will
become a reality, so let’s dream on!
Pure Oxygen Emissions

Turbine – Electric Hybrid Power

The supercar concept recently released by Jaguar with its C-X75 model is
mind-blowing. The vehicle features a revolutionary design, and it also packs
superb technicals.
Each wheel has its own motor that draws energy from a central lithium-ion
battery. The party pieces of the C-X75 are gas turbines, and Jaguar claims that
the car concept blasts from 0 to 60 mph in 3.4 seconds.
However, because the turbines are positioned behind the car, they must find a
way to stop the heat from meting vehicles positioned behind Jaguar C-X75 on
the street. If they can make that happen, we’ll see this technology materialize
by 2025.

Vegetable – Based Car Components

A car’s organic design has just reached a whole new level. Even
though Honda’s Air car concept is not the only one, the fact that
the vehicle features veggie-based body panels sure makes the
concept interesting.
A major benefit would also be reduced weight, particularly when
mixed with additional weight-saving features such as glass-
reinforced seat panels and urethane tires.

Electric Rickshaw

The idea of developing a car with pulling rickshaws seems rather far-fetched.
The latest Maybach DRS concept looks like an urban sombrero with an
edge.
It is a beautiful blend of a personal city car and a coffin. Yes, a coffin! But
leaving aside the weird design of this car, it certainly packs smart tech
advances we’d love to see in average vehicles.
According to Maybach, we might have to wait another 50 years to that to
happen.

Translucent Instrument Panels

Kia strikes again with a concept car known as Kia Pop. Based on OLED
technology, which by the way is insanely expensive, the vehicle takes a brand
new approach to car dashboards with translucent panels.
Basically, Kia Pop will provide improved vision than other car dashboards.
It’s a type of technology that is first displayed on halo models; afterwards, it
becomes mass-produced and included in compact cars and sedans.
Considering OLED technology is improving fast, we should expect new
vehicles to incorporate it by the end of 2015.

Increased Gesture Control

Building on existing voice control and knob technology, Audi introduced in
2011 an in-car feature that would offer unparalleled control ease of their cars.
But since technology likes to advance with every year that goes by, the
automaker’s new system is known as MMI touch (multi-media interface touch).
The new technology allows drivers to input characters with a finger to “write”
directly on the car’s touchpad.
A range of apps will be triggered, and the whole purpose of the system is to
ease the driving experience.
