Improvements in helmets (collaboration with Crizal ™)
Product design
Being a pillion rider to my boyfriend, I realized that whenever it rains, he always have
to use either one of his hands to wipe away the rain drops. It is already dangerous to
be riding in the rain, what more than to remove either of your hands to wipe away the
raindrops while riding.
Thus, I decided to work on the idea to ease motorist while riding in the rain.

2. Idea 1

3. Input a “screen wiper” at the visor.
Advantages and disadvantages
• Advantages
o Rider can switch on and off the “screen wiper” as and when they like.
o “Screen wiper” is curved to follow shape of the visor.
o Rider can just easily hit the button at the side of the helmet to activate
the “screen wiper”.
• Disadvantages
o Natural causes of wear and tear of things – “screen wiper” might wear
and tear easily. The heavier the rain, the more friction is caused.
o Might not be an ideal idea because riders need to check their “blind
spots” when they want to change lanes. In this case, the “screen wiper”
might block their view.

4. Idea 2

5. Collaborate Crizal™ into the visor.
Advantages and disadvantage
• Advantages
o Riders will not fear of having to remove their hand from their bike
handles (breaking gear/clutch gear) to wipe away the rain drops.
o Even with the rain drops on the visor, the riders are able to see clearly
through the visor.
• Disadvantage
o Natural causes of wear and tear of things.
In this case, I would choose Idea 2 because riders do not have to wipe away the
raindrops off their visors. Thus, this will not reduce the dangers of them riding on the
road (of having to remove one hand from the bike handles to wipe away the
raindrops).
So, I did a mini experiment. In this case, since the main problem is water, I did an
experiment with water and my spectacles. My spectacle lens are Crizal™ lenses.

6. Experiment
By using a spray bottle filled with water, I sprayed water on my spectacles. From the
outside, my spectacles looked like as though I wouldn’t be able to see through them.
But when I wore them, my vision was clear. It’s as though my spectacles were free
from water!
The reason why users are still able to see though Crizal™ lenses even with the
water droplets on the lenses is because the company makes use of Slide
FX™ technology. This technology makes use of hydrophobic (water repellent)
molecules so that the water doesn’t stick to the lenses and so that the water
slides of the lenses easily.

7. *picture that shows illustration
Thus, from this mini experiment, I can conclude that I am able to finalize my idea.
With the usage of Crizal™ lenses, the price of the whole helmet will be costly.
The price of just creating a pair of spectacles lenses cost around $150 (based
on how much my spectacles costs because the lenses are of Crizal™ lenses).
Thus, instead of inputting the lenses into the whole visor, the lenses will be
input into a portion of the visor; the eye level of the helmet.

8. 17cm
32cm

9. 6cm
4cm
To find the dimensions of where to input the Crizal™ lenses, based on
measurements, I’ll take 32cm (length of visor from right to left ear) subtract off
the 12cm (6cm – the distance of my eye from the end of the visor*2). Thus, I
will get 20cm. From there, I measured my eyes vertically which I got a 4cm.

10. From there, I will be able to conclude that I will input Crizal™ lenses in the
middle of the visor. The dimensions would be 20cm by 4cm.
