The issue with oral capable heads

Thanks for sharing this common head design. Very interesting. I hope that the Chinese manufacturers will appreciate the design input of the community. With that in mind...
In my opinion, the most critical missing feature in this common oral head design is the lack of hinged jaw. This would be easy to add if the head core were ABS, but it is admittedly not so easy for fiberglass.

I've been playing around with making oral head prototypes on for a while, and I discovered, to my surprise, that the hinging served two important functions. Most obviously, it allows a smallish mouth to expand as a larger...object...is inserted. If the elasticity of the insert and the hinge stiffness are in the right range, this will happen passively, even though it would require some active movement for an actual human mouth. If the head is life-sized or, worse, a bit smaller, then this may be critical.

The second advantage of the hinged jaw is that it will close as the aforementioned object is removed, enhancing the vacuum effect.

To give due credit, I discovered this effect when evaluating the design of the Japanese H.E.P.S. toy. It has a hinged jaw made of ABS or some similar hard plastic. The soft inner mouth layer is held in place with some small Nd magnets. It looks to me like the BoyToy heads might have the same effect; I've never tried them, though, so I don't know if the jaw is too stiff for this. If I'm not mistaken, Matt McMullen patented the Face-X system; I can see why.

My main interest has been in adding an external vacuum and some pneumatically actuated components, which obviously adds additional problems. The hinged jaw, as well as a mechanism (e.g. magnets) to hold a removable insert in place are both useful with or without external vacuum.

Many find doll orifice air compression and vacuum to be a detriment. Some dolls can be so tight that this factor becomes a problem and there has actually been a number of discussion on doll design and how to eliminate it.

But you do offer up a bunch of good ideas though. Thanks
TPE has good elasticity so probably has a lesser need for a hinged jaw than silicone. Silicone heads seem to require a open mouth for oral to keep from damaging it. And some extreme open mouth heads tend to lose the beauty. A hinged jaw might certainly help this where the mouth would close more when oral is not being performed.

I would definitely want a hinged jaw - for either TPE or Platinum Silicone heads (obviously, the more the merrier) -

Considering how many guys enjoy blowjobs - and are the primary customers for these - why Hasn't this been implemented already? Like, even that HEPS Kinsey thing was only released a couple years ago, and seems to be the only male sex toy that has Any type of feature like that (and it's not exactly a life-sized jaw).

The RealDoll face w/skulls sell for $1000 before shipping, etc. I would think/hope manufacturers like WM or even Sanhui would be able to price them somewhat less.

Magic Eyes makes the best blow job device on the market.

If ANY doll manufacturer would incorporate this device in their dolls, it would be heaven

You talking about the La Bocca Della Verita?

If so I own one and it's magical (no pun)

As much as I like Magic Eye's La Bocca Della Verita, I'd much rather have something better/even more realistic - which I think could be accomplished with a hinged jaw system, with tongue and teeth.

Plus, I think that would still satisfy fans of the sensations provided by the Bocca

Yes, thats the one!!

It seems like it would be a great fit to any of the dolls made in China (ORdoll, WMdoll. ect.) I actually tried to trim one down to install in an extra head I had. Almost worked

I have 3 TPE bodies and 9 different faces/heads - all are totally crap for oral sex. Too small, eyes bulge... very frustrating - it is hard to find many real life women who love giving blowjobs so we pay good money for these dolls and still no decent blowjobs.........

There appears to be room to make the mouth cavity wider by

1. making the TPE thinner in the cavity area of the 'skull',

2 making the cavity area wider on the 'skull' while maintaining TPE thickness,

3 widen the 'skull' cavity and reduce the thickness of the TPE covering the 'skull' cavity.

Why are the doll heads fiberglass instead of plastic? Wouldn't that make things easier to create new heads/faces/features for them? (I have no idea as to how the heads are made)

I'm addressing this issue in what I hope will be an easy fix.

Would a doll owner give up a dolls head turning ability to have a true down the throat oral capability?
The head could still nod forward and back, tilt left and right, just not rotate.

Yes

In a perfect world they would have a movable lower jaw, a deep throat, and still be affordable - but for now I propose this simple design change to manufacturers:

Get rid of the lower jaw structure on the current model TPE skulls, and bump out the upper jaw/skull front where it is currently missing from. It will now look more like an actual human skull (minus nasal bones) without teeth or lower jaw. Keep the hollow cavity where it is but make it as long as the skull interior will allow, and a little wider.

Now the upper/front face is firmly supported and won't deform or pop-eye. The lower "jaw" is not too floppy due to the amount of solid TPE, but is free to flex down (and cheeks out) when you're in it. If she's kneeling, you won't see the bottom of her jaw - just her pretty eyes and nose. If you are 69-ing you're looking at her rear. If you have a big mirror she just looks like her mouth is opening down, as it should, and it's 1000x better than what we have now.

The skull is still one hollow piece, just shaped a little different, and once the mold/form is made these shouldn't cost any more to manufacture than current models. Same with the TPE - less in upper face (sinuses) but more in lower jaw area. Not complex like a RD, just different than current design.

And for God's sake, close the end of the oral tube!

Vendors - You hand our money to the factories every day, and read our complaints here every night. Only YOU can tell them to improve the flawed design. Once you fix this I'll tell you how to manufacture durable finger bones.

Please fix it !

I agree with the OP's list. Although, I can get satisfaction with my doll seated.

I find the goose-neck to be useless when trying to re-position the head when my doll is on all fours, for example.
