Ergonomics and Anthropometrics

Anthropometrics means the study of human sizes, designers use this sizes and measurements when creating products.

Anthropometrics Ergonomics

Ergonomics is using anthropometric data when you create a product to

ensure it is comfortable for the user.

Scale drawings are used to draw large objects, just smaller. To draw big objects on a small piece of paper, you have to scale it down. This means drawing it smaller than it physically is but still

keeping the same proportions. You can also scale up, taking a small object and drawing it larger!

Scale DrawingsGrids can be used to

help when scaling up a complex image/drawingScales

Logo Evolutions

Advertising: Advertising is what companies do to promote their products so that people buy them.

Branding: Branding evolves creating a unique name and image for a product that will stick in the consumers' mind, mainly through advertising campaigns with a consistent theme. It helps to retains loyal customers.

Logo: A logo is a graphic mark, emblem, or symbol used to promote, identify and recognition a product or company.

5 Top Tips To Help Create A Good Logo

Simplicity is key. Don’t over complicate your logo with lots of detail, keep it simple, neat and

clear.

You need to make sure you communicate the style of the

company by selection the correct colours schemes and fonts that represent your company best.

The logo needs to look professional in order for people

to have confidence in your company/product

Make sure in your logo it is clear what the company does by adding

graphics/ visual aids relating to your company/product

You want you logo to be unique and original so customers don’t get your company confused with another which

could cost you business.

The Microchip!The brain of any circuit, this tiny yet powerful piece of kit tells all the other components what to do. Some microchips can be programmed multiple times to change the job they do. Each leg/pin has its own number as it will have a different input/output to all the other legs. Microchips are what has enabled us to have small circuits with enormous power in our day to day devices, such as phones and laptops!

Year–9 Subject–Design Technology Topic/Concept-Materials and Components

Basic ComponentsBelow are a range of electronic components you

should be able to identify visual, and explain their function.

WireUsed to connect components together and allow the flow

of electricity.

PCB (Printed Circuit Board)A PCB is used to minimise

the size of circuits, instead of using wires to join

components, they use tiny copper tracks.

ResistorThese come in many shapes and sizes, they are used to

reduce the flow of electricity. Resistors are

measured in Ω

CapacitorA capacitor stores electric charge in a circuit (not to

be confused with a battery)

LED (Light Emitting Diode)A low voltage light device,

used in hundreds of electronic devices.

DO NOT TOUCH THE METAL PART HIGHLIGHTED IN RED!

Only hold the soldering iron by the handle, highlighted in green.

How To Solder: The Basics

1. Touch component leg and copper pad with iron tip to heat up (3 seconds)

2. Engage solder with heated copper pad and component leg and allow to flow around the joint (3 seconds)

3. Disengage the solder with the heated area

4. Disengage soldering iron with the heated area

5. Allow a few seconds to cool

Sand paper: Sand paper is a type of coated abrasive that consists of sheets of paper or cloth with abrasive material glued to one face. Despite the name sand paper sand is now not used in the manufacture of these products as they have been replaced by other abrasives such as aluminium oxide or silicon carbide.

Files: Files are tools with a roughened surface or surfaces, typically of steel, used for smoothing or shaping different materials such as Polystyrene foam.

Modelling With Polystyrene foam

Files come in different shapes and sizes to create different shapes.

Below are some examples of what the files look like from their ends.

Sand Paper

Sandpaper is produced in a range of grit sizes and is used to remove material from surfaces, to make them smoother the lower the number

the more material is removed

Grades Of Sand Paper

Polystyrene foam

Polystyrene foam is a modeling material used to create prototypes of products, It is easily worked

and can be formed in to a range of shapes.

Modelling is a great way of generating a scaled prototype. This will help you determine whether your idea is going to work or needs modifying. A model allows you to test your

solution quickly and cheaply.
