Mask Task

PROBLEM SCENARIO

 

On 2nd August, in response to the second wave of  COVID-19 outbreaks in Victoria, face masks and coverings were made mandatory.

 

Face masks are now big business, with many companies taking advanage of the opportunity to cash in on a now highly sought after product.

As a well-known inventor, you have been approached by one of these companies, Magic Masks Inc. to:

(1) Research all the main options for face mask design

(2) Design and produce a mask that fits the criteria provided by Magic Masks Inc.

Magic Masks is looking for a mask that fits the following criteria:

The mask must....

1.  Be comfortable to wear for at least 11 hour straight. 

2.  Be adjustable to accommodate people of different shapes and sizes. 

3.  Provide a cover for the essential parts of the face, as ruled by the government's guidelines.

 

4.  Not be exceptionally unattractive to look at.

5.  Inexpensive.

Where to start?

FIRST... ask questions

"What do I need to know before I can design the mask?"

 

You cannot start designing the mask until you know more about what makes masks effective... 

THEN... answer your questions

  • Do this by starting to research.

  • Use the resources below along with resources you find for yourself.

  • Keep notes, writing down what you discover, so that you can include it in your digital workbook for section 1 of the EDP.

Remember to check that the sources are trustworthy!

"...choose a material you can tolerate wearing that has at least a few different layers, because that improves the filtering..."

 

"...it should fit closely against your face so you're not breathing out the top and sides of the mask... "

 

"...it should be close enough to your face that most of your airflow is actually going through the mask."

Mini task

PROBLEM SCENARIO

 

All country trains in Victoria have drinking fountains on them, since passengers get thirsty on long journeys.

Since the advent of COVID, the train company has been asked to provide disposable cups for passengers. This is seen as a safer way to drink from the fountain.

The train company is looking for a cup that fits the following criteria:

The cup must....

1.  Be able to be stored in a folded state. This will minimise the amount of storage room required for the cups. 

2.  Be made of a material that is able to be crushed easily by passengers. 

 

3.  Be made from a recyclable material.

 

4.  Be made from an inexpensive material.

 

5.  Be able to stand up when placed on a tray-table in the seating area.

 

6.  Be able to hold liquid for at least 3 minutes without leaking.​

Where to start?

 

The video below contains a tutorial on how to make a simple foldable cup from paper. However, it doesn't look like it would stand up on a flat surface very well!

Perhaps this design could be adapted to make it stand up?

Or maybe an additional object needs to be developed to help the cup stand up. For instance... an attachment, or an alteration to the tray tables.

 

There are lots of different options!
