held products, based on the theme of wildlife.
Prototype -
A prototype is an early sample, model, or release
of a product built to test a concept or process or to act
as a thing to be replicated or learned from. It is a term
used in a variety of contexts, including semantics, design,
electronics, and software programming.
Prototype
:A life sized scale 1:1 working model of a design
requiring testing, development and evaluation.

Block Modelling
: These help to determine the shape, dimensions and surface
finishes by constructing an accurate representation/model of the final
product. The external surface should show all details that would be
present on the final design. As the name suggests block modelling is
made from a solid block so the prototype/model will not contain any
internal detail or moving /working parts.
Polystyrene foam (Styrofoam) Brittle in tension, lightweight, with good heat
and sound insulation Available in blocks and used for product-modelling

Material Tools Used Advantages Disadvantages Safety Biodegradabl e Styrofoam File/Rasp Sand Paper Filler Acrylic Paint Great for 3D models. Difficult to achieve high quality finish. Use a ventilated area and a mask when cutting and finishing. No Balsa Wood File/Rasp Sandpaper Acrylic Paint Stronger then Styrofoam. Can act as mould for vacuum forming. Takes longer to shape. More expensive than Styrofoam. None Yes Plasticine / Clay Fingers Shaping tools Very quick. Can be vacuum formed. Easily recycled. Difficult to achieve a good finish. None Yes
Polymorph Hot Water Fingers Really quick to mould into shape. Easy to use. Only able to mould into shape once.
Take care with hot water and moulding material when hot
No

Covering any Errors
Filler can be used on any model to cover over any mistakes. This sticks itself to
the model and allows you to finish the filled in section with sandpaper. Filler
will also take any finish you plan to apply to the overall model design.
Finishing Block Models
The model needs to be finished to a high standard. It will firstly need to be
finished using various files and rasps to finish the design to its final shape.
Secondly sandpaper needs to be used. You will need to use various grades
from rough to extremely smooth to ensure a quality finish. The colour and
material finish can the n be added either with paints or spray paints. This
provides a quick drying coloured finish that can provide different finishes
including gloss, matt, satin, coloured and clear.
Block Modelling using CAD/CAM
A model can be manufactured once a detailed 3D drawing has been produced
on an accurate 3D drawing package. The design can then be sent to a CNC
machine where the design is transferred into a series of numerical code. The
CNC machine then uses the code to manufacture the 3D model. The process is
accurate and fairly quick. However, training is required to draw the design and
operate the machine combined with high set up costs.

Producing a Block Model
The foam is supplied in rectangular blocks which can be cut easily using both hand and power tools. The best way to approach this type of modelling is to build your shape up from smaller blocks rather than cutting away from a large block. Each piece is drawn on the block in pen/pencil and then cut out using a vibrasaw/scroll saw/hegna saw or bandsaw.

When answering the design questions the products is hand held and for children so please consider the following:
Children – are generally young people aged between 2 and 12.
Ergonomics – Ensuring the product comfortable, safe and meets its function.
Anthropometrics – Ensuring the product is the right size, using children’s hand, finger, palm
sizes etc.. as design information.
Social - Is the designed product aimed correctly at the right audience and is it inoffensive? Moral– Is the design safe for children to use?
Cultural – Is the design acceptable for children of different origins and backgrounds? Material – Include block modelling material choice with justification.
