Presentation Drawings are used in design, advertising and promotions. It helps potential consumers to see what a product looks like.

 

Design Drawings contain all the specifications and measurements needed in the manufacturing phase of the Technological Process. It is used to set the machines and tools in the factory

 

For both of these types of drawings the Communication Graphics in your Drawing Portfolio are used. 

 

Copy the notes, from the attached pdf document, into the correct spaces on page 5 in your Technology File.

 

It is important to protect your ideas and designs, because if someone copies your product the competing product may be sold for less money than yours. Consumers will buy the cheaper product, no matter if it is not as good as yours. Underline the notes about patents and protecting your income.

 

Consumers choose products according to the 7 design factors in your notes.

Read and underline the notes on the Technological Process on pages 5 & 6.

 

Aesthetics: Refers to what a product looks like.

A box of colour pencils where all the pencils are painted white, may not sell as well as one where each pencil is painted in the colours it comes in.

 

Affordability: The cost of a product will determine how many consumers can afford to buy it.

A pair of handmade designer leather shoes will cost more than a pair of mass-produced canvas shoes.

Only a few important businessmen will be able to buy the fancy shoes, but even a teenager's allowance makes the cheaper shoes affordable, so that many more pairs will be sold to a wide variety of consumers.

 

Ergonomics: Is all about comfort. 

A shirt made from scratchy fabric will not feel comfortable to wear. A badly designed chair will be uncomfortable or even painful to sit in, because it does not support the body as, and where, it should.

 

Durability: A well-made product, used properly, ought to last a long time. 

A pencil is relatively inexpensive, because it gets shorter every time it is sharpened. It will need to be replaced often and it is expected not to last. You do not expect a single pencil to cost the same as a kettle.

A car is expensive and cannot be replaced every few months when something breaks. Replacement parts should be available and inexpensive, so that the vehicle will be roadworthy for years and years.

 

Functionality: This refers to how well a product works, or how logical it is to figure out how it works.

Using an ATM is difficult for people in wheelchairs or short people, because they cannot read the screen. 

Water-fountains with press-buttons to open the tap is also challenging. Some have a foot pedal which makes it more functional, because more differently abled people can use it.

 

Safety: We see all the (obvious) warnings on everyday products. Have you ever wondered why?

Using a product in an unexpected way, or incorrectly, may be dangerous. The manufacturer and the designer put these warnings on their products to protect themselves against lawsuits.

Scratching your ear with a pencil may rupture your eardrum. It was not designed for this use, but many people do it, because a pencil is a very ergonomic length and thickness for doing just that.

 

Target Market: Who is expected to buy or use a product will determine the cost and look of it.

Dad is a journalist and needs to be in constant contact with colleagues all over the world. His cell phone is the latest model with the very best in camera technology. It cost a lot of money.

His tween daughter only needs a basic smart phone for emergencies and her parents will not spend more money on it than they think is necessary. Of course it had to be the one that comes in pink with purple sparkles, because a black phone is SO boring!

Granny, who is afraid of technology, will not like or use a smart phone, so she has one without access to the Internet and social media platforms. Her phone is bright orange and glows in the dark, so that she can see where she left it.

 

 

To test your knowledge of the Tecnological Process you can complete the exercise on page 7 in your notes. 

1.  Colour in the drawing according to the descriptions given. 

2.  Take each problem with the glasses and decide which design factors will be affected by it.

3.  Write the design factors in the order of importance in the space provided for each issue.

4.  This exercise should be finished at home.
