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.
