Introduction • Nowadays, many people like to

keep their things that have esthetic value such as handicrafts or cutlery set in a display cabinet.

• But, usually the display cabinet in market today are quite expensive.

• Therefore, we are trying to create a modern display cabinet that have stylish but affordable.

Objectives

• To create something for displaying product

• To create a portable and affordable cabinet

• To create display cabinet with modern look and better features

• To apply the knowledge that we have learn in GMI

Principle of operation(electrical part)

• Firstly, the power supply for the motor is switched “ON” or connected to the circuit.

• Then, the motor will start running an rotate the center display pillar.

• Next, the other two power supply for the lights is also switched “ON”.

• The LED in the display centre and the bulbs in the base will turn on.

Material selection & product design

• The design of our product is simple but have stylish and modern look. It also have better features compared with the ordinary one.

• We choose to use Perspex (Polymethyl methacrylate) as the major parts in our product to replace the glass.

• We decided to use Perspex because:– Not fragile– High strength– lightweight

• Other than Perspex, we also decide to use wood as the material for the body.

• It is because wood have high strength and easy to shape.

Step by step instruction(1 of 3)

Gather all the materials and equipment needed

Proceed to the mechanical part first

Cut the parts to the required dimension (wood & Perspex)

Bend the Perspex to the required angle to be functioned as door

Assemble all the part together according to the product drawing

Proceed to the electrical part

21


Build 3 simple electrical circuit (for motor, LED & bulb)

Put all the electrical part such as power supply, switch, and the bulb in the base to prevent them from get damaged

Connect the motor to the center pillar

Do some wiring to the LED so that it can be put in the display centre

After finish everything, cover the base with wood to make it more stable

Finally the product is ready to be use

23

Safety features• The main body is made from Perspex

which is very light and rigid compared with glass.

• The wood parts has been polished with the orbital sander or sand paper in order to get a smooth surface.

• The electrical part is build in the base which is surrounded by wood to prevent it from getting damaged.

• The power supplies used are from low voltage (9 volts) batteries which are essential to prevent electric shock caused by high voltage.

Troubleshooting procedures(1 of 2)

PROBLEM REASON SOLUTION

No electric supply Open circuit Check the main switchCheck the power supply using a multimeterMake sure all the wire are connected

The LED is not functioning

Wrong connection of electronic circuitWrong polarity of the LED

Check the electronic circuitMake sure that the polarity of the LED is correctChange the LED

25

Troubleshooting procedures (2 of 2)

Problems encountered and countermeasures

(1 of 4)

PROBLEM COUNTERMEASURE

Failed to get accurate angle for the door in the first try

Do some adjustment to the bending machine (hot wire strip heater).

The blade of the universal fret saw has broken during the cutting process

Replace the blade with a new one.

27


(2 of 4)

PROBLEM COUNTERMEASURE

The first motor that we use is not afford to rotate the center pillar

Replace the motor with more powerful motor

The door is not fit when it has been assembled.

Do some adjustment to the dimension and assemble the parts carefully
