  1. Working techniques (procedures)
  1. Economic considerations
  1. Materials and their properties
  1. Information technology
  1. Technical drawingto transmit the idea of an object
  1. Knowledge of physical and scientifitc concepts

Develop the idea

Construction

Idea

Check

Need

Analyse the need or problem and the possible constrains

Study similar cases and their solutions (background)

Propose one or several solutions

Agree and choose the best solution

Prepare plans and measurements

Choose yhe necesary tools, materials and labour. Prepare an estimate (of cost)

Prepare a time frame and plan the construction

Construct and test

Evaluate

Write the final report

Summarise and analyse the background

Classify and select the data that is most useful

Order this mformation svstematically in topics.

Consider technical aspects that could affect the protect. (Use connected to books, catalogues, the Internet, etc.)

Make a note or relevant practical details related to the data

Find information about previous solutions to this type of
topic subject problem

Design an individual idea

Explore the possibility of using new matenals.

Introduce minor modifications or combme models you find
interesting.

Use existing models and draw possible vanations to adapt them to your needs

Agree and choose the best solution

You can combine the positive aspects of several designs to make the definitive product

You can create a table to help choose the best design.

Construct the desing

Before constructmg the oblect, decide how to make each piece

If something appears difficult to do, find that solution first. The
problem may be more difficult to solve later.

Drawing is the first step to buildng.

Draw the pieces in the order you are going to make them

Demde how to iom the next piece before you draw it

Views of the complete object: these give us an idea about what the fmal prolect will look hke and how it will work.

Se parate pieces: these are views of each piece that makes up the whole obiect These drawings define exactly what we need

Overhead view, side view and front view: we use these views togive technical details of the size and exact shape of the pieces We write the measurements of the pieces on these drawmgs

De tails of the way pieces are joined: to solve techmcal problems We use an appropnate scale and draw them m perspective.
