The Design Process When designing your project you will be concerned with the design process. You will begin by identifying a problem and you will end the project by evaluating the article that you have designed to solve the problem.

This design process requires you to consider many factors and make a number of decisions. There are many different methods or routes for doing this and the one which you choose for your project will depend on the nature of the problem. This section introduces you to a framework which will help you your design work.

The framework for the design process is a series of linked stages which will help you to solve the problem. At each stage you will need to refer back to the previous stages.

A typical design project will consist of the following stages: 1.

The Design Brief

2.

Investigation

3.

4.

Evaluation

5.

Development

6.

Materials All designers must have a good knowledge of materials and their properties. In doing so, they will be able to make good choices when selecting materials for design.

When working on you project you will have to consider materials and be able to select the best material for the job.

The materials commonly used in schools are:  Wood 

Metal



Plastic

3

Wood There is a huge selection of different timbers available. This range can be split into two groups: 1.

Softwoods

2.

Hardwoods

Softwoods Softwoods are timbers which come from trees which are coniferous (evergreen).

This means that they do not shed their leaves in winter. Coniferous trees usually have needle like leaves and there seeds are found on cones. Softwood trees are fast growing and they tend to be cheaper to buy than Hardwoods. Softwoods are often used in the construction industry.

Types of softwoods include: Scots Pine, Spruce, Red Cedar and Douglas Fir.

Scots Pine

Red Cedar

Douglas Fir

Hardwoods Hardwoods come from tress which are deciduous. This means that they lose their leaves in winter. Hardwoods have broad leaves and have few knots. These trees are slow growing and are expensive to buy. They are often used to make expensive furniture.

Types of Hardwoods include: Oak, Beech, Walnut, Teak and Mahogany.

Oak

Beech 4

Mahogany

Manufactured/Man Made Boards Manufactured boards are made from recycled woods. The recycled woods are cut into fine pieces and are glued in a large machine to make a flat board. Many boards have a veneer on top to make it look nicer or like a more expensive wood.

Manufactured boards are cheap to buy and are often used for flat pack furniture.

Types of Manufactured Boards include: MDF, Plywood, Blockboard and Hardboard.

M.D.F.

Plywood

Blockboard

Finishing Wood A number of steps should be carried out when finishing Hardwoods and Softwoods and are shown below: 1.

Sand the wood to remove pencil marks.

2.

Raise the grain of the wood with a damp cloth.

3.

Sand the wood again to smooth it.

4.

Varnish the wood to make it waterproof.

5

Metal There are two main groups of metals: Ferrous and Non-Ferrous.

Ferrous Metals Ferrous metals contain iron. This makes the metals magnetic and causes them to rust.

A type of Ferrous Metal is Mild Steel. Mild Steel can be recognised as dark grey in colour and heavy in weight.

Non-Ferrous Metals Non-Ferrous metals do not contain iron and are therefore not magnetic and do not rust.

Types of Non-Ferrous metals include: Aluminium, Brass and Copper.

Aluminium

Brass

Copper

Pure Metals Some metals are pure metals meaning that they contain no other elements. Pure metals include: Aluminium, Copper and Tin. Alloy Metals Alloy Metals are metals which have a mixture of elements in order to create metals with certain properties. Alloys include: Brass, Steel and Bronze.

Finishing Metals A number of steps are carried out to finish and polish the surface of metals: 1.

Rub the metal with Emory Cloth.

2.

Rub the metal with Wet and Dry Paper.

3.

Rub the metal with Steel Wool.

4.

Polish the metal with metal polish (Brasso) and a cloth.

6

Plastics Synthetic plastics come from chemicals that come form coal, oil and gas. There are two main groups of plastics: Thermoplastics and Thermoset plastics.

Thermoplastics Thermoplastics can be heated and shaped then harden when cooled. They can be reheated and reshaped. These types of plastics have plastic memory and return to their original shaped if reheated.

A type of Thermoplastic is Acrylic. Acrylic is available in a wide range of colours.

Thermosetting Plastics Thermosetting plastics can only be heated and shaped once. Once the plastic has been shaped and has cooled it cannot be heated and shaped again. Thermosetting plastics are often used for products which are going to going to get hot.

A type of Thermosetting plastic is Urea Formaldehyde. Urea Formaldehyde is strong and scratch resistant.

Finishing Plastics A number of steps are carried out to finish and polish the edges of plastics and are shown below: 1.

Cross file the edges with a flat file.

2.

Draw file the edges with a flat file.

3.

Rub the edges with Wet and Dry paper.

4.

Polish the edges with metal polish (Brasso) and a cloth.

5.

Remove the film from the plastic.

Acrylic is most commonly used in schools and has a thin plastic film covering the surfaces of the plastic. The plastic film protects the surfaces form scratches while it is worked on.

Technology Timeline Homework During class time you will have discussed what you and your classmates felt to be technology. You should pick one item of technology and create a timeline for that product.

You will have to choose your product then find out when the product was invented, and how it has changed over time until the present day.

Your timeline should: 1. Show pictures of the technology as it changes over time 2.

Contain dates of when the product changed

3.

Describe the product and how the product has changed (how it looked, how it worked, materials etc.).

Your timeline can be completed by hand or on the computer and should be well presented on a piece of A4 paper. Try and remember one interesting fact about your chosen technology to share with the class next time in CDT. An example of a timeline is shown below.

Recycled Toy Homework Children around the world have very different lifestyles.

In wealthy countries we produce huge amounts of waste which we bury in the ground. Much of this waste is produced by companies using unnecessary packaging on their products. In wealthy countries children’s toys produce a huge amount of packaging waste as well as the waste caused when the toys are finished with.

In poor countries, where many of these toys are made, children don’t get toys as presents because there is only enough money for essential items such as food and clothing. Many of these children use the little waste their family does produce to make their own toys.

Your challenge is to: 1.

Design and make a child’s toy using only found/waste materials (You must not use glue, cellotape etc.).

2.

Create a poster/factsheet discussing 

Three facts about waste/recycling



Three facts about children’s lives in poor countries like South Africa

The toy’s will be judges on imagination and the use of found materials, as well as the quality of facts presented with the toy.

Merits will be awarded to the best three entries in each class as well as a certificate.

The best entry overall will win a prize!!!

Prizes will be awarded to the best three entries overall.

•House points will be awarded to the best three entries in each class.

•Toys will be
