Refined Dust Mask with Eye Protection: Phase Two Industrial Design Soft Goods product development


in the last video we took a look at a
proof-of-concept mock-up of a dust mask with an integrated eyewear to keep you
safe while you’re working in your shop in this video we’re gonna take a look at
the further design process of this soft goods product what is it gonna take to
make it manufacturable different materials colors finishes and make it
look really great so that the consumer is gonna want to buy it when they see it
on the shelf my name is Eric Strebel I’m an industrial designer welcome to my
channel about product design and making I hope that you like and joy and become
a subscriber make sure you give the video a thumbs up and then you hit the
bell hit the bell again so you get the little parentheses around it that way
you’ll be notified every time I have a new video for phase 2 of this project
we’re gonna sketch right on top of one of the images from the proof-of-concept
from the last design face so now we’re taking a look at the aesthetics and
functionality and the manufacturability of such a product
we’re gonna have some vents for the person to breathe that’s something that
the last mock-up or proof-of-concept did not have we’re gonna take a look at
manufacturer ability how things kind of go together so that they are fit and
finishes better it’s a little bit more comfortable adjustability how the
glasses kind of attach those sort of things and materials fit and finish look
and color in this face in a regular design project you would probably take a
look and explore multiple concepts instead of just one like we’re doing
here so you would take a look at different styles and colors materials
and finishes that sort of thing before we move on with this project I just want
to let everybody know the design and making merchandise is here t-shirts
hoodies and stickers for your shop it’s my way of saying thank you for
everybody’s fantastic support and will help me continue to make awesome content
so super quick the first thing I do is I 3d print out
plastic sort of mouth and nose piece I use some basic dimensions that I measure
just with a ruler and I translate that into a piece so I can sort of see if my
concept is gonna work and it does appear that it’s gonna work I think in general
it’s way way too early in the design process to use modeling CAD modeling and
3d printing the only reason that I go to a CAD and 3d printing in this instance
is because of this grille with the holes for the mesh in hindsight I probably
should have just Matt modelled a little mesh piece and built the thing out of
cardboard it would have given me a lot more flexibility so either cardboard or
like a styrene or something like that I spent so much time modeling it in the
computer that I don’t think it was worth it and it’s something that I should have
done by hand now if you have the resources and you have a dedicated you
know box jockey that’s gonna sit there and model your hand wave sketches then
that’s a different deal most designers don’t have that flexibility and I
certainly don’t so we’re just gonna print out the 3d piece here and this is
gonna give me my base piece that I’m gonna use and modify pretty heavily here
as we move forward in the project scraping it off the 3d printer here and
we’re gonna clean off all the support material on the backside real quick now
that being said there is definitely an upside to 3d printing this part it is a
pretty strong piece that’s made out of PLA and it’s some good structure ability
it’s symmetrical on both sides I don’t have to worry about that so let’s start
working on the side pieces that are going to connect onto this mask I’m
using a piece of 3 millimeter craft foam you can buy this at any craft or hobby
store it’s actually quite well suited for this kind of a project it’s flexible
it has some strength so as an alternative material to leather which I
don’t think is an option really for a kind of a budget
dust mask in it in this case I think this type of a foam is a good material
to sort of simulate some sort of a flexible material maybe like a TPU or
silicone or something like that in this case so I’m modifying the
mouthpiece here to make it fit my face a little bit better and I clean things up
with a file I like using files instead of sandpaper they’re flat straight and
they give you a nice surface finish and I feel like a little bit less dust and
just a little bit more control over the surface that you’re finishing all right
I want to talk a little bit about the colors that I’ve chosen here and you’ll
see I’ve chosen a white material and some of you would say oh my gosh a white
dust mask but you know that’s quite a common thing actually they’re very cheap
dust masks they’re all white sort of material and I am definitely going for a
little bit more of a sci-fi kind of menacing kind of look maybe something
from like a Final Fantasy or whatever where I’m gonna attempt to do this dust
mask in some lighter more space type of colors and thus the silver that I chose
for the grille and the white for the sides and I really like that kind of
look it’s not super dark it also reads better on film of course so we’re gonna
start to attach the straps and I could simply sew right through that foam
material onto the straps works halfway decent just be careful
here when you’re using this kind of stretchy material it’s pretty tricky too
so you really gotta push it underneath the foot of your machine if you don’t
have a walking foot machine it’s stretchy and it doesn’t grab really
great on to the teeth on the bottom alright at this point we want to do a
kind of a test fit to see if things are gonna start to work out in terms of the
side pieces how they get mounted on to the mouth and nose piece I’m going to
use some double-sided sticky tape here to merely attach the foam onto the
printed part alright we’re gonna use these off-the-shelf
one-way valves these are the valves that allow the person to breathe or exhale
out while using the mask okay so that looks pretty good actually
fits onto my head quite well allows me to breathe and creates a halfway decent
seal across my face you’ll see that little bend in the side of the mask
causes the foam to create a little void and the vents that actually work a
production mask like this would have a filter and so I’m using some filter
material here that I am basically just sewing up and this is gonna go right in
front of the mouth and in this case I’m just gonna pop it in for production you
probably have some sort of a frame or something that you could lock this down
with and be interchangeable to use and be replaceable but for right now we’re
just going to set it in there so let’s work with some bondo here’s some
polyester body filler to attach the I wear to the nosebridge art very much
in the same way that we built the proof-of-concept mock-up we’re basically
using the glasses as a guide or a squeeze and we’re letting the polyester
body filler set up around it so that we can move the eyewear in and out and have
it be replaceable this would also be like a production feature so this area I
purposely didn’t model it because I knew that it’s gonna take too much time it’s
gonna be so much easier just to do it in bondo and it’s gonna give me so much
more flexibility in terms of design figuring out the exact form of
everything it’s just gonna be so much quicker for
me to do this then modeling in a computer and giving me so much more
flexibility things are starting to come together especially with the body filler
here it gives me a ton of options you know lets me explore the form in
this nose area which I really wasn’t happy with before first up we’re gonna
repaint these one-way vents we’re gonna put a little bit of primer on them
and ultimately we’re gonna paint them like a blue color a blue grey but they
need a little bit of primer so that the paint will actually adhere to them okay well it was painting those the
polyester set up and it kind of got away from me a little bit so I’m gonna get
out a little or an old bandsaw blade here and I’m just gonna saw through to
get some of these flat plains surfaces back normally I would do that when the
material is all kind of rubbery and I can just cut it with a knife I like
using files that I mentioned before they are fantastic for getting nice flat
surfaces and great way to quickly rough in surfaces so for a plastic or wood or
plaster I find them a fantastic way to do things by hand you’ll see I have a
right and a left version and I really like the left version a lot better a
little more chiseled look I find the result of that right side there’s a
little bit too heavy so I’m gonna duplicate that over and put some bondo
onto the mask where it needs it so I can make both sides symmetrical and again
this is what I sort of like about doing hands-on stuff is it gives you the
option to test and model stuff as you go on the fly if you have that time and
flexibility I find it just so much better than doing stuff in the computer
because that just takes so much time or I think this is a quick fast and easy
way to come up with design variations and test out different things and see
what you like you know the car guys do this all the
time they’re using clay and I just love to have that flexibility to be able to
change things on the fly and make adjustments as needed so when the body
filler is still pretty soft it’s super easy to sculpt it with a knife here or a
very rough file and I like using that it’s a very easy quick way to do that
you also notice I have a piece of tape down that
put down on the PLA 3d printed parts so that I don’t get any polyester into the
lines the print lines next I switch right to a file and I rough in all my
surfaces that way just find it infinitely easier than using a species
hand paper that ultimately gets clogged up the files are easy to clean with a
brush yeah if they get clogged and you can just keep on going and they stay
sharper for a so much longer after the file I’m gonna switch to a card scraper
especially a piece of spring steel again the car guys use this all the time to
sculpt their clay and I find it a great tool I use it actually a lot on 3d
prints just for cleaning up 3d prints instead of sandpaper stay sharp for a
long time and it’s just really easy to use ultimately I am switching to a piece
of sandpaper and I use a hundred and twenty grit so it’s pretty rough I want
the texture of the body filler to at least be close to the texture of the 3d
printed part so I don’t want it to be too smooth and so I’m okay with some of
those scratches and rough surface that is left I use a paint marker here in
silver to just paint everything up that way I don’t have to mask anything off
and spray paint it just infinitely quicker the silver matches the printed
color of the silver quite well when you use some glue here to glue the foam
pieces directly onto the 3d printed part now that it’s finished I’m going to use
some e6000 the fantastic glue or something like this you could
certainly use a contact Samantha as well don’t have any so I use this to bond
everything together and some clamps to hold it while it dries and this works
out quite well I’m gonna make a little leather piece that goes on the strap
that goes over your head just to give the strap a little bit of flexibility or
a slight ability but when you put it over your head
so that you can easily get it and not snag it on your hair and just have some
adjustability I use some white leather here thinking that it’s gonna match the
foam that I have and it’s close it’s more of a cream and I don’t like it so
what I’m gonna do here is I’m gonna paint it which you know most leather is
just don’t realize it I’m gonna paint it to match those vents
and we use the same color paint a pretty light coat so I don’t need anything
super heavy-duty here I want to make sure that the edges get painted as well
I basically just put this in my spray booth here and then put a piece of
plastic bag over the rest of the mask and I tape off the elastic straps as
well so they don’t get all blue and little clips get painted blue as well
and so it has a really nice different kind of look and feel from any sort of
traditional mask that you might buy you know in a big-box retail store so that’s
as far as I’m gonna take this project for phase 2 if you are a manufacturer of
safety where dust masks that sort of thing respirators if you are 3m and you

  1. The one-way valve is sitting flush against the cheeks?! Also, there's not enough surface area on the filter part to make breathing comfortable. I know this is a proof of concept prototype but it fails to address the functional requirements.

  2. Back when i used to actively use Blender, i could make and iterate on a 3D model of such kind much faster than i could ever do in cardboard. A friend of mine on Softimage XSI could work even faster. Maybe the more rigorous CAD software is simply less suited for such quick and dirty operation. Most other 3D packages are also fairly slow to work with, except maybe Modo. Now that XSI is gone. Another problem is that ideally you'd have any geometry that you need to build around or connect to already in 3D, else you're running blind, though luckily a mesh of a human head isn't exactly a rarity nor that hard to make if you don't need it to be all too detailed.

  3. really good work , the only thing when you do the narration you say "Ah" like 2 thousand times jaja dont want to be like annoying just share a simple detail so you can improve 😛

  4. I would love to try so lightweight safety glasses with a scarf, as I am an avide woodworker. However I am becomoming allergic to Sawdust

  5. Awesome! I also love that you're UM2+ looks exactly like mine on the inside! All the plastic goobers.

  6. I need this. When and where can I get three, and how much am I going to spend? I am not a manufacturer but I am willing to work PR on it 😊

  7. Dust masks and safety glasses typically don't work together when doing any sort of physical work (like demolition work). The problem is that moisture from respiration and perspiration will condensate on the interior of the safety glasses rendering the worker blind from the fog. In these situations the worker is faced with the choice of either seeing or breathing which leaves lungs or eyes in danger. I hope that your concept solves this problem! Great video! Thanks for sharing. Good luck!

  8. I guess that it looks ok not sure maybe it's the long hair with wings at the neckline that makes it look bad show us on someone else with a MAN haircut lol awww man
