Need/Problem
Make
Design a range of
solutions
Write a design Brief
Carry out research
Write a specification
Develop the best idea
Identifying a problem or need
Tinker Toys Corporation is a small company that makes traditional children’s toys. Instead of
using plastic which is the material most toys are made from these days, they prefer to use
wood. They are also very concerned with the environment so want their products to be as
sustainable as possible.
Tinker Toys Corporation have lots of pieces of wood, 40mm x 40mm x 120mm, and want you to
design and make a wooden car with these left-over pieces of jelutong wood. The target market
will be young children.

Design Brief
A Design Brief is a short sentence about what you are going to design and make. When you write a Design Brief you need
to mention the target market and explain the problem you are going to solve or the need you are going to meet, but you
shouldn’t say how you are going to solve the problem.
Use the words, I am going to design and make…’
Example: Cat owners often have the problem that their cat scratches the sofa. I am going to design and make something
to stop cats scratching the furniture.
Writing a Design Brief - Write the design brief for the wooden car project below
Homework Task – write a Design Brief for the following problems:
Problem One: Many adults spill spaghetti down their clothes when eating. The sauce stains their clothes and can be
embarrassing.
Problem Two: Many children lose their glasses because they put them down when they are not wearing them and then
forget them.
Assessment Criteria
Level 3
Level 4
You can write a sentence about the problem you are going to solve, but do not
mention the target market, or, the problem you are going to solve is unclear
You can write clear design briefs that mention the problem you are going to solve and
the target market.

Research – Natural Timber: Softwoods and Hardwoods
Research can involve looking at existing products and analysing them, it can mean asking people questions to find out what they would like. It can also involve
researching different materials and manufacturing processes. In this project we are going to carry out some research into different materials.
Follow the PowerPoint and complete the table. Then draw a line from each box to the correct tree.
Coniferous trees are ___________________, needle-leaved, cone-bearing trees,
such as ___________________, ___________________ and __________________.
Broadleaf ___________________ trees often loose their leaves in winter, such as
___________________, ___________________ and ___________________.
Grow ___________________, usually stop growing in winter and produce expensive
___________________.
Grow ___________________ all year and produce cheap ___________________.
Often used for high quality furniture, interior woodwork, for example ___________________ _________________
Often used for ___________________ and ___________________.
Check yourself
1. Give 3 examples of a softwood
2. Give 3 examples of a hardwood
3. Why do you think hardwoods are usually more expensive
than softwoods?
4. Describe the leaves of a softwood tree
5. Describe the leaves of a hardwood tree

Research - Manufactured Boards
One problem with natural timber is that wood from trees only comes in relatively narrow widths. This is because of the sizes of the tree trunks. One solution to this is
to use manufactured boards. This type of wood is produced by gluing wood layers or fibres together and often uses waste wood. Manufactured boards can be made
in very large sheets and are available in many thicknesses.
MDF – made of fibres
Plywood - made of layers
Check yourself
1.
What is a disadvantage of natural timber?
2. What are manufactured boards made from?
3. Give 2 examples of a manufactured board

Existing Products
When designing new products, designers often look at existing products as a source of information. Product analysis is not
just about describing them, you should identify the good features of the product and ways it might be improved.
Follow the PowerPoint in class and complete the spider diagram.

Design specification
The specification is a list of all the needs that the product must meet. The specification is very important as it states what
you can and can’t do when you are designing a product. It is also important that you list all the constraints – for example, if
you only have wood available, then this is a constraint. In which case it would be wrong to design a product that had to
made from wood or plastic.
Write a specification for your wooden car. Think about the following points: aesthetics, customer, size (look at the first
page of this booklet) function, safety and materials.
Freehand Sketching
You need to be able to communicate your ideas using sketches. Follow the exercises to
practice your freehand sketching.

Design Ideas
Design a range of ideas for your wooden car. Remember to include the wheels, draw them with
a compass – 50mm diameter. Look back at the design specification and after you have drawn
each idea annotate it to explain how the design meets the specification, or how it doesn’t. This
work will be assessed, so check out the Assessment Criteria.

Orthographic Projection
Orthographic drawings are also known as working drawings. They communicate the sizes of the product and show the different views so the product can
be made. Practise using the examples from the PPP.

Production Plan
A production plan is a set of instructions for making a product. The tasks need to be in the right order – some tasks need to
be done before others. A flow chart can be used to show the order things are done. Different shapes are used for different
things.
Use this shape at
the start and end
Use this shape to
check something
Use this shape for
a task
Use this shape
when you need
certain tools for
that task
Example – Drilling holes in the middle of the wheels
Get Safety Goggles
& Apron
Start
Are you following the
correct safety
precautions?
Machine Vice
4 wheels
Clamp 1 wheel in

Is it secure?
Line up drill bit with centre of
pilot hole and start drilling
Has the drill bit gone
all the way through?
Homework Task
Draw a flowchart to explain how to make the housing joint. Make sure you include all the stages – including safety
precautions and make sure you use the correct vocabulary (names of the tools)

Evaluation
Once you’ve finished making your wooden car, you need to decide how good it is. Take a step-back from your product and
look at it critically. Ask yourself the following questions:
1. Does it work?
2. Does it meet the design specification?
3. Could you improve it?
Evaluating your progress is serious business, so use the PPP to help you. Your evaluation will be assessed using the criteria
below. As well as reading your evaluation, your teacher will also think about how well you worked during the practical
lessons.
Assessment Criteria: Working with Materials

Level 5
You recognize what you did well as you made your car, and suggest things you could
do better in the future.
You identify where evaluation of the design and make process of your wooden car has
led to improvements.
You identify what worked well and what could be improved to overcome technical
problems.
You reflected on your design as they developed, recognising the significance of
knowledge and previous experience.
You checked your work as it developed, solved technical problems and showed some
evidence of creativity as you modified the way you worked. You have tested and
evaluated your wooden car, showing that you understand the situations in which the
product will function.
