Take a look at the video below for little inspiration.
GCSE Product Design Examination
Monday 6th June 2011 AM.
Collect your revision guide from your Design & Technology teacher.
Please ensure you bring a pencil, 2 black pens, a ruler, a rubber and a sharpner to the examination.
The examination will be split up into to 2 parts, there will be 2 themes for the exam:
1. Temporary shelter.
2. Kitchen tools/equipment for over 65.
Good Luck!

Job titles, roles and responsibilities
Materials and components
Name two materials that could be used during manufacture.
1. Aluminium
2. Nylon

STANDARD COMPONENTS
A pre-manufactured component or a standard component is a component that you can used that has already been made. For example, a handle, screws, nails, pre-manufactured vacuum form mould or knock down fittings. Advantages are they are already made for you, you do not have to invest in workers or materials to make new parts.
Product Packaging and Labelling
1. Promotion
2. Information
3. Protection
Material- corrugated card, bubble wrap, polystyrene
1. Transport in bulk
2. sell only to local markets
What is the purpose of a barcodes?
Barcodes are used to inform the retailer the price of the product and the quantity available.
1. meet legal requirement
2. Inform customers
3. Branding
Keep of rain/ damp conditions
Remember to add labels to your packaging, the materials you will use and three appropriate dimensions (measurements) for the packaging.
Tools and equipment
Planning
Planning can include a production plan (ghant chart), flow chart and a seqence drawing.
You may be asked to create a flow chart for either a ride on toy or portable seat for outdoor use. Ensure you include details about the following for each material you use:
MARKING > CUTTING > SHAPING > JOINING > FINISHING
Watch the video below to find out about the production of the mechanical toy.
Inputs > processes > outputs
Health and safety issues
Product safety must be considered. For example; products with no sharp corners, the use of non-toxic paint and no small parts.
SAFETY STANDARDS
A Kitemark symbol printed on a product, labelling or packaging assures customers that the product has been tested for quality and safety. The kitemark symbols is awarded by British Standards
You also may be asked in the exam about workshop safety rules. Ensure you explain in detail about each safety rule and why it is a harzard. These are easy marks.
ICT/ CAD/CAM
Word Processor
A letter could be typed out and sent out to a range of companies to asked for specific information about existing chair for teenage bedrooms.
Database
Search, cross reference and present information quickly. Useful during investigation and research stage.
Spreadsheet
A spread sheet could be used to record the data received form the questionnaire, this could then be produced into graph to find out more information about your users needs.
Web Browser
A range of products could be analysed to see the best product on the market and to see the competition
Presentation package
To present information on screen / paper to a high standard, to explain the main features of a design proposal to an audience.
CAD Program
2D design could be use to produce part of the product and then part of the design such as a decorative pattern could be created using the laser cutter (CAM) or the product could be modelled on a program like 3D Rhinoceros so the designer can have a visual image of what the product can look like.
You could also be asked about CAD/CAM- Computer Aided Design and Computer Aided Manufacture
Advantages of CAD
Reliable, faster, accurate
Information can be saved
Photo realistic models can be created
Disadvantages of CAD
Hardware and software can be expensive
Training is required
Can be time comsuming
Advantages of CAM
Machines can operate in environments that might be harmful to humans
Quicker production times
Accuracy and quality in production
Disadvantges of CAM
Cost of buying and installing machinery are very expensive
Loss of jobs for workers
Workers at automated factories can have very little job satisfaction, as all they do is monitor the machinery.
Environmental issue
In the exam it may also ask you about the product life cycle.
State one advantage of following a product cycle graph for
The designer- shows at what stage to introduce modifications to product
The manufacturer- to see how well a product is selling and when to update and replace it, increase/decrease production
There are 5 diiferent stages to the product life cycle these are:
The product is introduced in small numbers, highly priced, exclusive item
2. Rise
The product is advertised, begins to develop in popularity, details simplified and cheaper versions produced
3. Peak / maturity
Saturation point is reached most consumers will have bought it by now, the product is readily available at affordable process through mass production
4. Decline
The sales fall and the chair is sold at discount process in the sales
5. Obsolescence
The product is no longer manufactured
one-off, batch and mass production
One-off production or custom production
Batch production
Mass Production
For the exam you will need to know what the differences are. Watch the video below to find out more.
One off Production
- Final product is expensive
- Highly crafted product and highly skilled people
- Labour intensive
- Specific requirement for user
- One person or a small number of people
- Produced one at a time
- Original piece
- High standard of quality control
Batch Production
- A production line is set up
- The production line can be changed quickly, so that different products can be made.
- Team of people produce a require number of the same product
- Products can be produced a certain number at a time
- Templates, mould, former, jigs are used.
- Each worker completes one task and passing down the production line to the next worker.
- The workers are semi skilled or unskilled.
Mass Production
- Long period of time
- A semi-automated or fully automated production line is set up
- Each person is trained for specific job
- Large numbers of products are manufactured
- Sometimes require very little human input
- A lot of time and money to buy equipment and change tooling
- Cost of item is lower in the long term
- Expensive tool and machinery are used
- Limited training of staff as the product and equipment changes slowly.
Design ideas and annotation
Try to draw the mechanical toy in 1 point perspective. Draw an L shapes and an upside down
T shape, draw the cirle shape handle, pick your 1 point perspective point, make sure it is not too close, draw the perspective line in faint, then draw the mechanical toy in 3D.
Make sure you draw the designs accurately in 3D isometric or 1 point perspective.
Most importantly labels all the drawings using ACCEESS FMM
Aesthetics
Cost
Customer
Environment
Ergonomics
Size
Safety
Function
Materials
Manufacture
Write down the materials you will use and why. The joining methods you will use, the finishing methods you will use and why and finally write down how your final design meets your design specification.
You may be asked how you will produce your product in batches on this question
To make the mechanical toy use in batches I will use
Templates, jigs and CAD/CAM.
- I will use CAD/CAM to create the main character. I will design it on 2D design and cut it on the laser cutter.
- Jig can be used to make the holes for the dowel rod.
- Template can be used to create the background and foreground shapes.
Quality Control and Quality Assurance
Quality checks are used as part of quality control and quality assurance. Some quality checks are easy to do, but other quality checks are more difficult. For example:
Easy Quality checks
size
weight
construction
Difficult quality checks
attractiveness
comfortable
fashionable
Quality Control
Quality control is a series of checks which are carried out on a product as it is made. (quality control point are shown on a flow chart using a diamond shape.)
Quality Assurance
Quality Assurance checks the systems which make the products, before, during and after manufacture. It ensures that consistency is achieved and that it meets the required standard.
