Towards a Better Mask – 2

An internal project under Rattl has been to try create a better mask for the (Covid) times.

While it is possible we fail to actually create an ideal one, the exercise so far has been a learning one.

This is post #2.

This was part experiment, part fun. I’ve always been fascinated with the idea of using car components for things. For instance, a dream is to someday replace the sofa in the hall with car seats.

Back to the topic, affordability comes from using empty soup bowls from an earlier food delivery. 😛 

As for the funny white extensions on the sides, they are cardboard (from some box) and inside it lies the “protection” – A decent quality car air-conditioning filter. The entire AC filter comes for a few hundred bucks, and I barely used 10-15% of one. There’s a section of folded filter, and a second single layer where that white section joins the s̶o̶u̶p̶ ̶b̶o̶w̶l̶  mask via a ~1.2 cm opening [below].

So that’s double layer of protection! The plastic section wouldn’t allow the virus in. And the front is transparent to allow for better human interaction. With this particular prototype, the nose cut-out was not deep enough so the transparent section focused more on the beard, but ideally, it would give a view of the mouth and part of the nose.

If you’ve seen the criteria listed in the 1st post of this series, this one prototype addresses:

Among the basic criteria:

  • Protection
  • Affordability
  • Partly achieves ‘breathable’
  • Addresses gaps on the sides of the nose

And among Good-to-have features:

  • Transparency (almost on this one, but should be easy to fix)
  • Partly addresses good circulation (by being a few centimeters away from the mouth and nose, it allows for a more open, relaxed breathing setting as opposed to most regular masks)

Of course the air filtering packs on the sides are huge and unwieldy. General comfort too wasn’t great as I simply used the elastic bands from a used surgical mask so it was tight (to the point it almost took my eye out when the nose protection cushion slipped out and the strain of the bands pushed the jagged plastic edge in my eye as I was fumbling around trying to take a selfie with the mask on.

Anyway, till the next prototype…

Towards a Better Mask – 1

An internal project under Rattl has been to try create a better mask for the (Covid) times.

While it is possible we fail to actually create an ideal one, the exercise so far has been a learning one.

Some basic criteria considered:

  • protection against the virus (> handkerchiefs and cloth masks, at least)
  • affordability (pointless if a solution for a global problem is not affordable by everyone)
  • breathable (one reason a lot of people wear it on their chins, etc., is because many masks aren’t exactly easy to breathe in for more than a few minutes)
  • address the gaps on the sides of the nose that are not adequately covered by masks without the nose wire/pin

Good to have features:

  • transparent (at least around the mouth), to enable quality interactions
  • good circulation (ideally explicit unidirectional channels for inhaling and exhaling

Will share any findings or updates as and when I get to work on it.

To start with, these were some initial sketches. Faces 3 & 5 were a quick rough digital trace from an image.

Some advantages of a full-face mask are:

  • less strain of elastic bands on the ears
  • an ignored aspect – the relatively more ‘breathing room’ inside the mask, while being better shielded

Airbags and the Height of Drivers

Airbags and the Height of Drivers

About a month ago, Honda introduced a new concept airbag for their vehicles. The challenge for them, was protecting drivers from angular collisions. In such cases, the driver’s head seemed to slide off the airbag and cause injury.

The inspiration for them…Baseball mitts (or gloves).

The result. A frontal airbag system that deploys three sub-airbags that secure the head similar to how a baseball is caught.

After you check out the video below, is another challenge I was wondering about.

Here’s something I’ve been wondering about.

When an airbag deploys, there is a rapid inflating of the airbag [more on how that works, here], and a more gradual but simultaneous deflation by way of tiny holes in the airbag. This is to reduce the damage done by the face hitting the inflating airbag.

But even then, airbags can result in everything from a burning sensation and abrasion on the face, to facial burns, chest, cranium and shoulder injuries. Among those most affected, are children and short adults.

Shorter people are closer to the steering wheel, and therefore the airbag.

Which brings me to a question. Since short adults driving are closer to the steering wheel, from where the main airbag deploys, is it possible to vary the inflating pressure based on how front or back the driver’s seat is?

Let me know your thoughts.
