The materials from this set of notes are to be used solely for educational

purposes in Teck Whye Secondary School. They are not to be sold or

distributed. The resources that have been used in this set of notes are

1. http://www.technologystudent.com

2. Ripley St. Thomas School ---http://resmat.blogspot.com

The objectives of this course are

1. Pupils should be able to appreciate and experience the design process

by understanding the design task, setting relevant design

specifications and generating interactive ideas.

Design & Technology is a subject that will help you to discover more about

the world that we live in. You will learn how things are designed to meet

peoples need, how they function, how technology is involved to enhance the

functions, and appreciate the value of the balance of aesthetic and function

as good design.

Designers go through a process in order to arrive at an appropriate solution

to meet the needs of the target users. We called this the Design Process.

A lot of thinking and reflection is done throughout the entire process to

achieve a good end result.

Design Process

A common design processused by designers to help them to designsystematically is shown in the flow chart below.


Do you notice that there are arrows

forward and backwards throughout the

entire process? These arrows show that

designers will constantly reflect upon the

previous stages and use the researched

information to make sound decisions for

their design.

This process is also a very useful model to help us with our school projects

irregardless of the subjects or CCA areas. In Design and Technology, we will

further break down each of the 5 stages into smaller sections to help us

simplify the task.

Do the terms found in the last flow chart look very foreign to you? Dont

worry! We will understand and appreciate the Design Process better as we

embarked on a real-life project from this point forth. Your very

knowledgeable and approacheable teachers will facilitate your learning and

help you along the way. This means that you will play a major role inproducing creative yet appropriate ideas and making important decisions in

designing a solution for your task. You will need to constantly reflect upon

your research and previous work to make sound decisions for your designs. I

repeat your teachers will guide you along, but they will not be making

decisions for you. Remember this, you will now be the most person in making

decision for your solutions. However, mark these words, Choices will lead to

consequences. The consequences will either turn out to be positive or

negative, depending on the quality of your thoughts and actions. You will be

assessed according to these.

Have fun and enjoy the learning process!


Project: The Handheld Electronic

Device Charging Station

Design and make a Handheld Electronic

Device charging station that can hold atleast 1 device for recharging purposes. Your

solution should not exceed 150 x 150 x 3 of

cardboard.

Design Activity 1: Analyze this!

Work in pairs. Look at the Charging Station in the picture below and

answer the following questions in the space provided.

1) How does it work? Explain with evidence based on the features of the

object.

2) Suggest others how the charging station can be used.

Design Specifications

Design Specifications are conditions, criteria, directions that will help us to

stay focused when designing. Points such as; safety, general size, what it will

do (its functions), general properties of the materials needed, who it is for(eg children), circuit requirements and other points you feel are important.

Below are sample design specifications on an Infant teething product.

Weight - The product should not exceed 0.001kg in weight.

Size - The product should at least 60 x 60 x 10. (Dimensions are in mm

only.)

Material - The product should be made of a soft material, so that babies can

bite while teething.Appearance The product should have more than 1 colours (especially red

and black), so that babies be attracted to it.

Safety The product should be smooth in texture. There should not be any

rounded corners.

Comfort for user There should be a non-slip grip to help the babies to

Hold it properly

Storage The product should be stored in areas not exposed to excessive

sunlight or heat.

Performance The product should be able to attract the attention of babiesby rattling.

Maintenance The product should be easily cleaned by rinsing with water

and dried quickly.

Design Activity 2A:

Use the following categories to help you to work out 3 design specifications

for the product that you have selected. Choose only those design factors

that are more suitable for your product. Refer to the previous sampledesign specifications while writing yours.

Design Activity 2B: Design Specifications for your Charging Station.

List down the design specifications based on your learning from Design

Activity 1. Some examples are done for you. These are to be part of your

actual Design Specifications. You should have at least 6 points including the3 given to you.

1) Size: The product should not exceed 150 x 150 x 3 (Length x Breadth

x Height)

2) Function: The product must can hold at least 1 device for recharging

purposes

3) Material: The product must be made from cardboard. (Materials size

given: 225 x 15 x 3)

Design Activity 3B: Many ways of holding a slip of paper

By displaying on a stand

By gaps

Designing becomes more and creative when the product seem to telling astory. Would you like to have one of these products? How could your product

tell a story?

paper. Illustrate your ideas in the space provided below. Annotate your

ideas and labelling your parts and describe how your idea works (Work in

pairs)

Design Activity 3B: Many ways of holding a slip of paper
