Hi All!

I am a senior industrial design student at Georgia Tech and have used a divacup, mooncup and have recently tried the femmycycle! I'm loving my cups, but I think they could be improved. I am currently working on a project to design a new menstrual cup. My design involves a valve at the base of the cup, so you could empty it without removing it during the day ie when you are in a public space without access to a sink (this would be particularly helpful for women with a heavy flow like me). I'm working on making the design SUPER secure, so no worries about leaks from the bottom etc.

What do y'all think? Is this something that cup users would find useful? Any feedback would be super appreciated!

They already exist. Google Victoria's Love. And look at menstrual cups at eBay for knock-offs of the VL.

In order for the stem to be comfortable, it has to be narrow. And it would have to be too narrow to allow thick flow or clots to pass. It also makes the stem un-trimmable.

And I think it shouldn't be a big deal to remove and dump a cup so it's a whole lot of engineering that isn't really necessary.

Thanks for the quick response! I have seen those. I don't want the stem to stick out of the body. I was thinking the valve/seal would sit at the base of the cup (in the place of a diva cup stem but wider to allow larger clots to flow through). You could pull it so just the base was sitting outside of the vagina and empty from there.

Good luck! Show us your design when you're done.

I think if the base has to come out a bit in order to empty it wouldn't really work for those with a high cervix like myself.

I was just going to say this--plus, you'd have to pinch the base a little bit just to pull it down and if the cup is full to capacity, blood would then splash up out of the top.

I would be interested in the design as long as the cup + stem is short enough (or has a low cervix version like femmycycle)and the valve is large enough to pass a thick flow and clots. Those two issue are the only thing keeping me from trying a Victoria's Love knock-off.

I think if you can come up with a good design, tonnes of us will be interested. The ones that exist right now are rather bizarre. Keeping the valve inserted is a start. I'm no engineer, but I think another challenge is getting the fluid to flow out even though there is no air intake at the other end (?).

AIWO cup
I just came across the AIWO cup today. I'm not sure where the stem is supposed to go, but that would be another design to review.

There are a few cups with valves, but I don't think they're very popular. I suspect that for some people, this emptying method is much less convenient than intended. I know I regularly find less than liquid menstrual fluid and small bits of tissue in my cup. Seems like that might complicate things.

Good idea
Hi, this is really an good idea.

While this kind of product is already exist in the market.

1st, Victoria love menstrual.

2nd, Aiwo Menstrual cup.

The second one is the most advance product right now.

It wouldn't work for me... I have a fairly low cervix and the base of my cup needs to be stemless, round and smooth or it'll chafe me.

I love the idea however what happens with clotting which would block up the valve for me. But I'm no industrial designer so I'm hoping you've got a way around that and uncomfortable protrusion. Can't wait to see the finished result.
