2022 Secondary 1 Design and Technology- Project 1: Bag Tag

Design Brief

Design and make a bag tag for student to attach to their bags so that it will be easy to pull the zip.

Design Specifications

• The bag tag must be made of aluminium.

• The bag tag must be able to provide a good grip for zipping action.

• The bag tag should have an interesting shape generated using “ lines & circles.

• It must have a hole to insert a ring to connect the zip of the bag.

Term 3 Week I - Ideation

Objectives

To introduce various methods of ideations but to emphasize that we are using lines and circles in Project 1.

• Lines and circles;

• SCAMPER;

• Random ideas;

• Shape borrowing.

ACT 1 : Ideation - Lines & Circles

• Sketch 4 different designs of bag tag using combination of 2 lines and 3 circles.

• Sketch 4 different designs of bag tag using combination of 3 lines and 3 circles.

• Sketch 4 different designs of bag tag using the sample template with symmetrical lines.

• Make use of the 2D template provided at the end of the Resource Booklet.

Refer to the example given below.

Term 3 Week 2 - Sketching in isometric

Objectives

ACT 2 : Converting to 3D sketch (isometric)

• Click video on converting 2D sketch to isometric to learn how to convert 2D sketch into isometric.

• Place your completed 2D designs on the Isometric underlay and draw out the thickness lines and complete your 3D.

Refer to the examples given below.

Term 3 Week 3 - Dimensioning & rendering

Objectives

• To teach students the proper way to do dimensioning.
