Do a Survey of 20 people. create your own questionnaire of 4 relevant questions and distribute. Summarise with Pie chart or paragraph. even mood boards! A lot of work for little marks, dont dwell on this!
End Brief that you have produced from your research, including target market, time frame, general aesthetics, but dont repeat word from word of the initial brief.
Use
Access FM as titles for the spec point
Specification point explaining what it is relevant to
Primary/Secondary Level of importance *no stars but numerical 1-10 importance*
Explanation ; Use technical vocabulary
How can it be evaluated? What could you do at the end to say it worked.
Consider quantitative and qualitative statements
my product could/should...
My product must...
Quality checks?

The bigger the area the better the product is.
Do a small one for
EACH
design
Rate your design from 1-10 for each spec point.
fill the page with at least four designs.
Comment on the pros and cons, likes dislikes and refer to spec as much as possible
Use a similar table to this and state the properties of materials - even if you aren't going to use them! It shows you have considered the best material
Sometimes its best to keep your best idea for this section and under develop it for this part!
Make sure you integrate the changes from your friends
This enables you to have the best initial design but keep the good ideas until the next couple of pages. Its needs to be developed
Get two of your friends to tell you Appropriate comments that will help you! not: I don't like red / Round edges help the shape look cool.
Always refer to the Specification
This section shows a development of your appearance - the outside and inside of item / colours, textures, materials? dont forget to put prototype phots in too!
Choose areas to develop as well as the overall appearance. If there are hinges or interesting items. highlight and develop.
Use your drawing skills learnt in class and ensure it has at least two colours on the page. Put a background behind them and/or a shadow.
construction is the product net, sizes, rough dimensions to produce the product
Each part of the design has a component and each part should be a material. Just which material out of many. Would a window be made from metal? why not? explain why and then choose another.
Prepare - A4 CAT Book
Whitchurch High School
Dylunio a Thechnoleg
Consider the function:

Durability,
Weight,
Strength, (Do not simply say strong material – relate)
Conductivity,
Ease of use,
Cost, (Do not simply say cheap material – relate)
Availability,
Safety,
Consider the aesthetics of a material: colour, decoration, pattern etc that could be used in that part.
More info the better, but in a concise format such as bullet points.
Consider your power source and the components within. If possible, get an enclosed unit and design around this, such as a garden lamp
Consider each part of the product, even the interior if it needs to do a function
Two alternative methods explored for each part once again.
Annotate and justify decisions made by giving reasons that the method chosen is the better because…...
Joining like and unlike materials Such as metal to wood using adhesives of bolts.
Use of CAD CAM can be used such as the laser cutter or CAM machine for plastics and wood.
Permanent and temporary fixings such as bolts, screws or silver soldering and adhesives?
Different joints in wood? Remember the dovetail / lap joints completed in year 10.
The number of parts, components or products the design has.
Dimensions of parts, components or products should be reviewed with a SKETCH orthographic drawing. It’s basically a sketched side, Front and top view of the product and or components, dimensioned roughly with reasons of the particular material size.
working sizes of areas of machinery, equipment or materials may be necessary.
Multiple numbers of identical parts should be shown for mass and batch production.
Highlight how this is efficient and cost saving
How it can be produced safely and the quality checks to ensure that it is produced with a quality finish.
Consider your power source and its components. How will these be obtained and produced. How much does an ‘AA’ battery cost on its own compared to one bought in a batch of 10,000?
Recycled materials and where materials can be obtained?
(tessellated = fit on the material with minimum waste)
How much do the materials cost? Check the internet!
Relate it to the analysis made on page 1

Justify all decisions made and show the relevant quality control issues to achieve a good finish. For self-finished materials such as plastic sheet you may need to focus on the edge treatment.
How will the design will be finished and the quality control issues necessary to achieve a quality finish. This section focuses on the final product and consider all the parts of the design.
A range of possible finishes for each part. Don’t put paint for all of the parts unless it is the best choice. It may be put into a type of table once again and have alternatives and select to most relevant.
The processes / stages necessary to achieve a quality finish should be highlighted. Pre-manufacture checks on wood would be check for cracks in the panel and irregular grain and knots. Make sure the grain all flows in the same direction before marking out. How are you going to ensure that you do this?
The advantages and disadvantages of each finish should be explored.
The cutting out of one part by hand or cutting via CAM. But CAD CAM can be costly and slow if you only need one part.
CAD/CAM is expensive initial outlay but cheaper if its mass produced.
Accuracy and consistency of construction should be put in. EG; the laser cutter can produce multiple parts in mass manufacture, which ensures the accuracy, but it needs a clean every 4 weeks to ensure a consistent cut. Put this in and add as a quality control point for the manufacture process.
Time allocation with the process. Such as; drawing a part to be laser cut can take longer than actually manually producing it.
Refer to how skilled a process can be, whether its drawing on CAD or creating a dovetail.
Pre-manufacture, Manufacture and Post manufacture checks.
Accurate and clean lines in your drawing. Use a darker line for the outer line and thinner defined lines within the design.
No annotation
.
3D main drawings with optional 2D extras.
Quick background or shadow of the product to give 3D aspect.
Detail ‘bubbles’ showing intricate or fiddly parts of the design.
Full colour with shading and materials showing where applicable.

This page should be able to be given to someone else to produce the product. If they cant, then it isnt successful!
Ensure all dimentions are put on an orthographic projection, or several 3D drawings
How the work is tesselated on the materials
How the design is constructed
Materials used for each component
Finishes that need to be applied to each of the parts. Is it before or after construction?
You can use any format, such as ; CAD, Orthographic projection, Exploded Drawing, Step by Step.

This should be series of logical procedures for making the product.
Gannt charts or flow charts, sometimes both to ensure you hit all stages of manufacture
Break down the making into a series of stages
* Time for each stage
* All processes involved in making it ( Machinery, Tools )
* Quality Control points ( Check woodgrain and knots in wood)
* Lasercut is better finish because...

Very important to completely prepare this at home. Spend as much time as possible writing it out so that you can just copy it when you are under CAT time. ITS WORTH 10 MARKS!!!

!! ALL RELATE TO SPECIFICATION !!
Does it satisfy all the specification points?
Dont say what you would do differently, thats the next page.
Be critical but constructive, provide evidence, maybe get target market views of the product to back up your ideas.
General conclusions on how the design meets the needs. Difficulties? Successes? Time management? Quality controls?
Paragraph the specification points with headings used in the spec page, but ensure that it is a continuous piece of work. no bullet points or short hand. An essay style sheet.

Very important to completely prepare this at home. Spend as much time as possible writing it out so that you can just copy it when you are under CAT time. ITS WORTH ANOTHER 10 MARKS!!!
Reflect on page 13, use annotated sketches, what and what should you change now because... and production methods
Talk to two users and get thier thoughts on the product. Outside persons would be better, and take it seriously
Relate to;
Aesthetics
Function
Quality
Processes used
Time allocation
Durability

Material appropriateness
Four images of the finished product only!
2 images of the outside,
1 of the inside (possibly)
1 of any important focal area/feature
Prototyping is essential to check to see how it goes together.
!! PREPARE !!
Use the Guidance sheets that the teacher gives you
Track all times under the CAT and even the Non- CAT
Sketches should be short and concise
Utilise your time wisely. Christmas should be up to page 11/12 and start making on your return after christmas.
The teacher is there but not to give you the answers! its your work and your GCSE. Remember all your work from Year 10
Good Luck and God Speed!
Remember that you get marks for quality of presentation.
TIME MANAGE!
Did i say prepare?
Get music on to stop disturbances and FOCUS!
Find and print picture and info of competitor product and analyse using access fm. Make sure analysis is relevent and concise.
document your time after it is complete. you may go back to it months later!
Initial brief given to you by me
Page one is hard work, but remember that it is only 5/180 marks. dont go M

Specification point importance, explaining why it needs to be/ should be included in the final product
Put your initial design here straight from page three. It should be well drawn, fit 1/3 of the page with Access FM for annotation.
CAD modelling is a great tool here. it is an accurate prototype!
