Week 13

 Week 13

👀FOR THIS WEEK WE LEARNED ABOUT:

• Operating Principles
• Mechanism Designs

Part 1: Operating Principles 🙇

Why do we need to learn operating principles?

It is because all device, apparatus and equipment are designed based on working principles that are either mechanical, electrical, chemical or magnetism.

Examples:

1. The separation principle behind distillation is differences in relative volatilities.
2. The separation principle of solvent extraction (LLE) is a solute can distribute itself in a certain ratio between two immiscible solvents.

These are the examples we have learned in the separation processes and simulation module.

Next activity: We are given a task to think about the principle of our chemical product.

What is the principle of our chemical product (deodoriser)? 💭

💬

Our chemical product is based on gas adsorption principle. Adsorption is the operation whereby a gaseous mixture is separated into its different components by contacting a bed of porous solid particles. The purpose of deodoriser is to get rid of odour in an enclosed area without much ventilation. For example, we can use this deodoriser to get rid of durian smell in an enclosed room. 

Next, we will require some research about the density, properties, and characteristics of gas components in the air.

After that, we move on to.....

Part 2:  Mechanism principle 🙌

6 Essential Mechanism in functional prototypes 

1. Actuators
   
   
   
2. Cams
   

   

   
   
   
   
3. Gears

   

   
   
4. Lever

   

   
   
5. Ratchets

   

   
   
6. Springs

   

🎉Next activity: Design Ping Pong Ball Launcher (Let's have fun~)

Our tasks 💨:

•        Design a Ping Pong Ball launcher that can shoot and reload ping pong balls.

•        The device should be able to hold at least 5 balls

•        Device should propel the ball with stored energy

•        Mechanism can be fully automatic, semi-automatic or fully manual.

•        Your design should include sketches, short notes and a clear description of the propulsion and reloading mechanisms

🔫After having a long discussion, we came up with our final design 🔫:

Ping Pong Ball AK47                                             

The End...
