The bird’s nest

CONSTRAINTS AND CONSIDERATIONS:

The Design Brief contains lots of information.

To work out what we have to include in our design, we made a list of the Constraints and Considerations from the design brief in the table below.

Constraints	Grade	Considerations	Grade
Stability	3	Chain	3
Brightness of light	4	Paint	1
Position of switch	6	Design	2
Quality	1	Glitters	5
Strength	2	Rattle	8
Portability	7	Beeper	6
Efficiency	5	Stickers	4
		Rubber	7

TOP FIVE PRIORITIES:

      Constraints                       Considerations

1.       Quality                                                1.    Paint

2.       Strength                                               2.    Design

3.       Portability                                            3.    Chain

4.       Brightness                                            4.    Stickers

5.       Efficiency                                             5.    Glitters

EVALUATION CRITERIA:

1.       Will it last for at least two years without being destroyed?

2.       Will the brightness of bulb be enough to supply enough light at night during brownouts?

3.       Will the LED lights be lit when there is no light?

4.  Will the battery last long?
5. Will the artefact be efficient?

Torch Light Holder Design Process

DESIGN TASK:

We are to research, design and make a torch light holder and then we shall evaluate our work.

Design Brief:

    We are tasked to design and make a torch light holder that will be useful every night when there is no electricity.

1.     A 1/8 illustration board will be used.

2.     The design should be modified/modelled from a unique building.
