Global, Human, and Ethical Impacts of Product Design
INVESTIGATING PRODUCT LIFECYCLES
![Page 2: Global, Human, and Ethical Impacts of Product Design](https://reader036.vdocuments.us/reader036/viewer/2022062305/568166ae550346895ddaa4d8/html5/thumbnails/2.jpg)
Impacts
Human Throughout time, humanity has used
natural resources, animals, plants and inanimate materials, for its survival, consumption, and enjoyment.
It is often taken for granted things and resources will always be here.
Many times short term monetary gain is considered a priority.
![Page 3: Global, Human, and Ethical Impacts of Product Design](https://reader036.vdocuments.us/reader036/viewer/2022062305/568166ae550346895ddaa4d8/html5/thumbnails/3.jpg)
Impacts Continued…
Global Population:
- is growing at an exponential rate.
- shows a continual change in human needs and wants.
Energy: non-renewable resources are becoming more and more scarce.

Ethics
A set of moral principles or values; a theory or system of moral values.
The discipline dealing with what is good and bad and with moral duty and obligation.
![Page 5: Global, Human, and Ethical Impacts of Product Design](https://reader036.vdocuments.us/reader036/viewer/2022062305/568166ae550346895ddaa4d8/html5/thumbnails/5.jpg)
Ethical Design Dilemmas
Situations in which decisions you make are in conflict with what may or may not be morally correct.
Sometimes this is obvious right away, and other times it is not.
Solutions to open-ended design problems have dilemmas that designers face when creating the product.
Let’s look at some pictures of products or things and discuss the ethics involved.
![Page 6: Global, Human, and Ethical Impacts of Product Design](https://reader036.vdocuments.us/reader036/viewer/2022062305/568166ae550346895ddaa4d8/html5/thumbnails/6.jpg)
Steps in resolving ethical design decisions
1. Moral Clarity- identify the relevant moral values.
2. Conceptual clarity- clarify key concepts.3. Just the facts- obtain all relevant
information.4. Informed about options- Consider all
genuine options and alternative solutions.
5. Well-reasoned- Make a reasonable decision.

Design Analogy
Engineering design as a metaphor or model for thinking about moral decision making- in general, not just within engineering.
Like design, moral choice often involves alternative permissible solutions to dilemmas.

Product Lifecycle
Definition is the succession of strategies used by
business management as a product goes through its life-cycle. The conditions in which a product is sold (advertising, saturation) changes over time and must be managed as it moves through its succession of stages.
The goals of Product Life Cycle (PLC) are to reduce time to market, improve product quality, reduce prototyping costs, identify potential sales opportunities and revenue contributions, and reduce environmental impacts at end-of-life. To create successful new products the company must understand its customers, markets and competitors.

1. Raise and Extract
All consumer products begin their lifecycle with a dependence on the natural environment.
Some form of energy is always required to extract the natural resources from the earth or its atmosphere.
![Page 10: Global, Human, and Ethical Impacts of Product Design](https://reader036.vdocuments.us/reader036/viewer/2022062305/568166ae550346895ddaa4d8/html5/thumbnails/10.jpg)
2. Process
Raw materials are processed or refined.
Energy is required for the processing and refining.
![Page 11: Global, Human, and Ethical Impacts of Product Design](https://reader036.vdocuments.us/reader036/viewer/2022062305/568166ae550346895ddaa4d8/html5/thumbnails/11.jpg)
3. Manufacture
Manufacture Additional energy is
required as the processed or refined materials move through the manufacturing and assembly process.
![Page 12: Global, Human, and Ethical Impacts of Product Design](https://reader036.vdocuments.us/reader036/viewer/2022062305/568166ae550346895ddaa4d8/html5/thumbnails/12.jpg)
4. Use
Use Consumer products are transported
to stores (consuming additional energy) and are ready for purchase.
Products remain at this stage as long as they are usable or repairable.
![Page 13: Global, Human, and Ethical Impacts of Product Design](https://reader036.vdocuments.us/reader036/viewer/2022062305/568166ae550346895ddaa4d8/html5/thumbnails/13.jpg)
5. Dispose
Dispose When the product is no longer of use to us
and we “get rid” of it.

Concrete-
Made by combining four materials into a mixture of two parts: portland cement aggregate
![Page 21: Global, Human, and Ethical Impacts of Product Design](https://reader036.vdocuments.us/reader036/viewer/2022062305/568166ae550346895ddaa4d8/html5/thumbnails/21.jpg)
Portland cement-
A finely pulverized material made up of compounds of silica, lime, alumina, and iron.
Portland cement is created by mixing limestone with clay, slag, or shale and then burning the mixture in a rotary kiln.
The setting and hardening is the result of a chemical reaction between the portland cement and water called hydration.
![Page 22: Global, Human, and Ethical Impacts of Product Design](https://reader036.vdocuments.us/reader036/viewer/2022062305/568166ae550346895ddaa4d8/html5/thumbnails/22.jpg)
Alternatives to Portland Cement
Slag cement and Fly-ash cement are green alternatives.

Precast concrete-
Concrete products that have been precast in molds and then removed and transported to construction sites.
An example is precast concrete walls for building, which are often prestressed.
![Page 31: Global, Human, and Ethical Impacts of Product Design](https://reader036.vdocuments.us/reader036/viewer/2022062305/568166ae550346895ddaa4d8/html5/thumbnails/31.jpg)
Dimensional Lumber
is a collective term for harvested wood that has been manufactured into boards and planks. This process is part of something called wood production. Lumber is predominantly used for structural purposes but has many other uses as well. Lumber is classified as hardwood or softwood.
Lumber is supplied either rough or finished. Besides pulpwood, rough lumber is the raw material for furniture-making and other items requiring additional cutting and shaping. It is available in many species, usually hardwoods, but it is also readily available in softwoods such as white pine and red pine because of their low cost. Finished lumber is supplied in standard sizes, mostly for the construction industry, primarily softwood from coniferous species includingpine, fir and spruce (collectively known as Spruce-pine-fir), cedar, and hemlock, but also some hardwood, for high-grade flooring.
![Page 32: Global, Human, and Ethical Impacts of Product Design](https://reader036.vdocuments.us/reader036/viewer/2022062305/568166ae550346895ddaa4d8/html5/thumbnails/32.jpg)
Sheathing
Oriented strand board (OSB) is an engineered wood particle board formed by layering strands (flakes) of wood in specific orientations. It may have a rough and variegated surface with the individual strips of around 2.5 × 15 cm (1" x 6"), lying unevenly across each other.
OSB is a material with high mechanical properties that make it particularly suitable for load-bearing applications in construction.[1] The most common uses are as sheathing in walls, flooring, and roof decking. For exterior wall applications, panels are available with a radiant-barrier layer pre-laminated to one side; this eases installation and increases energy performance of the building envelope. OSB also sees some use in furniture production.
![Page 33: Global, Human, and Ethical Impacts of Product Design](https://reader036.vdocuments.us/reader036/viewer/2022062305/568166ae550346895ddaa4d8/html5/thumbnails/33.jpg)
Water Membranes
In building construction, a structure needs waterproofing since concrete itself will not be watertight on its own (but note concrete is easily waterproofed with additives). The conventional system of waterproofing involves 'membranes'. This relies on the application of one or more layers of membrane (available in various materials: e.g., bitumen, silicate, PVC, EPDM etc.) that act as a barrier between the water and the building structure, preventing the passage of water. However, the membrane system relies on exacting application, presenting difficulties. Problems with application or adherence to the substrate can lead to leakage. In the UK these membranes are rarely allowed below ground below the water table.

Asphalt Shingles
An asphalt shingle is a type of wall or roof shingle. They are one of the most widely used roofing covers in North America because they have a relatively inexpensive up-front cost and are fairly simple to install.
![Page 35: Global, Human, and Ethical Impacts of Product Design](https://reader036.vdocuments.us/reader036/viewer/2022062305/568166ae550346895ddaa4d8/html5/thumbnails/35.jpg)
Gypsum Board (Drywall)
Drywall (also known as plasterboard, wallboard, gypsum board, sheetrock, or gyprock) is a panel made of gypsum plaster pressed between two thick sheets of paper. It is used to make interior walls and ceilings. Drywall construction became prevalent as a speedier alternative to traditional lath and plaster.
In many places, the product is sold under the trademarks Sheetrock or Gyproc. In New Zealand the category is known as plasterboard or gib board (originally "Gibraltar board"), the latter being a proprietary brand name but now largely a genericised trademark

Finish Carpentry
Carpentry that involves the installation of finish woods, (and trim made of plastic or molded polyurethane materials) to provide a finished appearance to installed doors, windows, stairs, and other features of a building's interior. Elements include casing, baseboard, railings, mantels, louvers, paneling, and shelving.

Paints
Paint is any liquid, liquefiable, or mastic composition that, after application to a substrate in a thin layer, converts to a solid film. It is most commonly used to protect, color, or provide texture to objects. Paint can be made or purchased in many colors—and in many different types, such as watercolor, artificial, etc. Paint is typically stored, sold, and applied as a liquid, but dries into a solid.
![Page 38: Global, Human, and Ethical Impacts of Product Design](https://reader036.vdocuments.us/reader036/viewer/2022062305/568166ae550346895ddaa4d8/html5/thumbnails/38.jpg)
Carpets
A carpet is a textile floor covering consisting of an upper layer of "pile" attached to a backing. The pile is generally either made from wool or a manmade fiber such as polypropylene, nylon or polyester and usually consists of twisted tufts which are often heat-treated to maintain their structure.
