A product is the item offered for sale. A product can be a service or an item. It can be physical or in virtual or cyber form

1 Definition of a Product and Product Development

A Product is something sold by an enterprise to its customers. Product Design involves a broad approach to the designing and making of innovative / new products.

Product Development is the set of activities beginning with the perception of a market opportunity and ending in the production, sale, and delivery of a product.

Why Is Product Development Important?

• It is “big business” Hundred billion dollars• New products answer to biggest problems• A successful new product does more good for an organization than anything else.

Not All New Products Are Planned

• Microwave ovens• Aspartame (NutraSweet)• ScotchGard fabric protector• Teflon• Penicillin• X-rays• Dynamite

In each case, an accidental discovery -- but someone knew they had something when they saw it!

What Is a New Product?

• New-to-the-world (really-new) products (10% of new products): Inventions that create a whole new market. Ex.: Polaroid camera, Sony Walkman, Palm Pilot, Rollerblade skates, P&G Febreze and Dryel.

• New-to-the-firm products (20%): Products that take a firm into a category new to it. Ex.: P&G brand shampoo or coffee, Hallmark gift items, AT&T Universal credit card, Canon laser printer.

• Additions to existing product lines (26%): Line extensions and flankers in current markets. Ex.: Tide Liquid, Bud Light, Apple’s iMac, HP LaserJet 7P.

• Improvements and revisions to existing products (26%): Current products made better. Ex.: P&G’s continuing improvements to Tide detergent, Ivory soap.

• Repositioning (7%): Products that are retargeted for a new use or application. Ex.: Arm & Hammer baking soda sold as a refrigerator deodorant; aspirin repositioned as a safeguard against heart attacks.

• Cost reductions (11%): New products that provide the customer similar performance but at a lower cost. May be more of a “new product” in terms of design or production.

Breakthrough Innovations that Changed Our Lives

• Personal Computer• Microwave Oven• Photocopier• Pocket Calculator• Fax Machine• Birth Control Pill• Home VCR• Communication satellite• Bar coding• Integrated Circuit• Automatic Teller• Answering Machine• Velcro Fastener• Touch-Tone Telephone• Laser Surgery• Apollo Lunar Spacecraft• Computer Disk Drive• Organ Transplanting• Fiber-Optic Systems• Disposable Diaper• MS-DOS• Magnetic Resonance• Imaging

PRODUCT DESIGN AND DEVELOPMENT IN THE INDUSTRIAL ENTERPRIZE

2 Stages of product developmentA product usually starts as a concept which, if feasible, develops into a design, then a finished product. The following seven phases can be identified in a variety of product design and development projects.

1. identification of needs, feasibility study and concept selection, 2. system-level design, detail design and selection of materials and processes, 3. testing and refinement,4. manufacturing the product 5. launching the product, 6. selling the product, and7. Planning for its retirement.

2.1 Feasibility studyElements of feasibility study include:

1. Market research

2. Product specifications

3. Concept generation, screening and selection

4. Economic analysis

5. Selecting optimum solution

2.1.1 Market research

1. The range of features and the technical advantages and disadvantages of existing products, the mechanism of their operation, and the materials and processes used in making them.

2. Past and anticipated market growth rate and expected market share by value and volume.

3. The number of companies entering and leaving the market over the past few years, and reasons for those movements.

4. The reasons for any modifications which have been carried out recently and the effect of new technology on the product.

5. Patent or license coverage and what improvements can be introduced over existing products.

6. Profile of prospective customers (income, age, sex, etc.) and their needs in the area covered by the product under consideration.7. Ranking of customer needs in order of their importance.8. Product price that will secure the intended volume of sales.9. How long will it take the competition to produce a competitive product?

DESIGN 101 Page 5

Page 6: Product Design Handout week 3

10. What is the optimum packaging, distribution, and marketing method?

2.1.2 Product specifications

Product specifications give precise and measurable description of the expected product performance based on the qualitative descriptions of the customer needs. For example: a specification of “the total weight of the product must be less than 5 kg” can be based on the customer need of a “light weight product” and the observation that the lightest competing product is 5 kg. Similarly, a specification of “average time to unpack and assemble the product is less than 22 min.” can be based on a customer need of “the product is easy to assemble” and the observation that the competing product needs 24 minutes to unpack and assemble.

2.1.3 Concept generation and screening

• Product specifications are then used to develop different product concepts that satisfy customer needs.

• Some of the concepts may be generated by the development team as novel solutions but others may be based on existing solutions or patents.

• The different concepts are then compared in order to select the most promising option. • The Pugh method is useful as an initial concept screening tool.

2.1.4 Economic analysis

The economic analysis section of the feasibility study normally provides an economic model that estimates:

• The development costs,

• The initial investment that will be needed,

DESIGN 101 Page 6

Page 7: Product Design Handout week 3

• The manufacturing costs, and

• The income that will result for each of the selected concepts.

The economic analysis also estimates sources and cost of financing based on the rate of interest and schedule of payment.

2.1.5 Selecting an optimum solution

Factors involved in selecting an optimum solution:• customer needs,

• physical characteristics of size and weight,

• expected life and reliability under service conditions,

• energy needs,

• maintenance requirements and operating costs,

• availability and cost of materials and manufacturing processes,

• environmental impact,

• quantity of production,

• Expected delivery date.

3 What is sustainability?Essentially, sustainability in design and manufacturing has a lot to do with “doing better with less,” and embracing a broader view of product development – looking at the full lifecycle of the product and the impact that its design, manufacture, use, and retirement can have across the triple bottom line – that is, its impact not only on business, but on the environment and society, as well.

That said, sustainability isn’t just about “doing the right thing” for the environment or for society. It’s also about doing the right thing, financially. In other words, environmental and/or societal benefits must be paired with financial benefits in order to truly succeed. The good news is that manufacturers are increasingly finding that there is key business benefits associated with “going green.”

3.1 Design for Sustainability D4S is an ecodesign concept that has evolved to include both the social and economic elements of production. It integrates the three pillars of sustainability - people, profit, and planet, but goes beyond simply ―greening‖ products to embrace how to meet consumer needs in a more holistic, sustainable way [4]. It also is unique in that it can focus specifically on the needs of industry in developing countries. Companies incorporating D4S into long-term product innovation strategies strive to alleviate the negative environmental, social, and economic impacts along a product’s supply chain and through its life cycle—the ―cradle-to-cradle‖ mentality.

There are encouraging developments that contribute to the expanding knowledge base of sustainable product development.

These newly designed products and services offer:

increased functionality ease of use longer life spans easy disassembly or recyclability lower environmental impacts which can save the company money And improved materials sourcing and production which can positively affect

communities.

In other words, sustainability offers added value through better quality and lower price—the two motivators for most consumer decisions.

4 Sustainable Products to Follow in 2013:

1. PUMA's In Cycle collection, which includes footwear, apparel and accessories that need not be tossed in the trash at the end of their useful life, but can rather easily be turned into biological nutrients or taken apart for metals, textiles and plastic to be reused in making other products (or more In Cycle products). Particularly note-worthy in the In Cycle collection are this T-Shirt and these Basket Sneakers, both of which are fully compostable.

2. The BMW I series of electric cars, featuring the compact urban i3 and the dynamic i8 sports car. These two models are being built from the ground up as entirely new concepts with the goal of being 'uncompromisingly sustainable' for the next age of mobility. To help fine-tune the I series, BMW has been collecting customer feedback through an impressive 16-million-kilometer e-mobility field trial for its Active vehicle released last year.

3. The water center Coca-Cola is starting to build across Africa, Latin America and Southeast

Asia in partnership with DEKA Research and Development Corp. Each unit is designed to be

an entirely off-grid little cabin the size of a small café, powered entirely by solar energy or

biomass and featuring extra perks such as cell phone charging, some shade and a public

flat-screen TV. DEKA's water purification technology takes 'anything that looks wet'

(literally!) as an input and produces 1,000 liters of fresh drinking water per water

center per day.

4. Kraft Foods

Engineers at Kraft Foods wanted to find a more functional packaging

solution for their salad dressings. Their research in commercial food

service kitchens showed that operators typically had to go to great

lengths to get dressing out, spending time scraping the insides with a

spatula and even cutting the tops off the rigid jugs. After examining several designs, the engineers proposed a new solution: a significantly lighter, flexible, squeezable package made of nylon and polyethylene, branded the YES Pack, which stands for yield, ease and sustainability. The Kraft YES Pack delivers 99 percent yield or up to two extra servings of dressing per case, which reduces product waste.

• Assembly of packaging requires 50% less energy

• Packaging waste occupies 50% less landfill space

• Transportation of film involves 70% fewer CO2 emissions

• Restaurant operations enjoy up to 99% product yield, reducing waste

• Made with 6 oz less water per 2/1-gal case

• Discarded materials take up 86% less receptacle space

5. The up cycling Filabot, a one-of-a-kind plastic extrusion system capable of converting most

types of recyclable plastic, such as milk jugs, detergent bottles, soda bottles, shampoo

bottles, product packaging and many more, into usable 3D-printing filament. Talk about the

number of possibilities this opens up.

A fascinating project is making the rounds this weekend that could change the way we think of 3D printers. The Filabot is a robot that can turn scrap plastic into 3D printer filament, thereby allowing an almost endless supply of material for prototyping and manufacturing.

5 The future of product design

just as quality assurance is no longer a differentiator but a must-have, environmental lifecycle assessment will become the de facto standard -- if not the regulated standard -- for product design. A decade from now, designers won't consider these sustainable product design examples innovative -- they'll consider them obvious, and wonder why we ever

designed unsustainably.

5.1 Case Study I: Ergonomic Monitor An ergonomic monitor refers to a computer screen that has adjustable components that

allow for the user to maintain a healthy position while using the computer. Ergonomics is the

science of regulating work-related environments and equipment to best support the worker's

physical needs. In an office environment, ergonomics generally refers to the design and options

available in the computer workstation where most work is completed. Many office workers

report health problems related to repetitive movements and prolonged hours staying in the same

position. Ergonomic design aims to reduce the effects of the necessary use of equipment for long

periods of time. An ergonomic monitor is a key part of creating a work station that optimizes

productivity while also preventing physical ailments.

Common physical problems associated with computer use include eye and vision problems as

well as Work-related Musculoskeletal Disorders (WMSD). Eye and vision problems range from

pain to blurriness. WMSDs include muscle and joint pain and strain in hands, shoulders, necks,

and wrists caused by repetitive movements, poor positioning, fast pace, and working

continuously without sufficient breaks. An ergonomic monitor, paired with a more ergonomic

workstation, allows for a healthier workplace. The ergonomic monitor allows for appropriate

positioning and lighting to reduce the effects of long hours working at a computer workstation.

An ergonomic monitor has three elements: a tilting component, a swivel component, and a

brightness and contrast component.

5.2 Case study II: Ergonomic Chair

By the time, design faces great challenges in the creativity and reliability. As technology plays a great role, Utilities and tools become more creative in order to withstand the human needs and to comfort him as possible. So, we can take an ergonomic chair as an example versus an ordinary chair. You by default will use the ergonomic chair although you don't know why It is more expensive than the ordinary one. Simply, because the ergonomic chair is a re-designed ordinary chair but with achieving all the factors of comfort ability and lighterness. As for engineers, office

DESIGN 101 Page 23

workers, managers, clerks, lawyers and executives they took long time sitting and as a result they need to feel comfort on the chair they are sitting. This re-designed chair fulfills the customers' needs, satisfaction, and durability.
