It's amazing we could do so much better nowadays, and you want technologies that are over 10 years old. It is a pity to limit your imagination and your hopes to just minor changes to products currently on the market.
My problem with the product are:
For me when using a disposable diaper one should have to soak in urine and or fecal matter.
I also think that disposable diapers should be possible To be slipped on like a slip, or as a conventional disposable diaper, the side directly in contact with the skin should be breathable.
obviously the ISO absorption should be at least double the disposable diapers currently on the market.
there should be no external odor, even for faecal use, there should be no need for leakage barriers.
The side and the belt should be elastic, not something ugly as the pants.
Disposable diapers should not be very thick (the thickness impact the weight, and the size of the packaging which impact the shipping costs, and therefore the price.
My solutions to correct this problem are:
to avoid contact with fecal and urinary matter the solution is simple simply add under the nonwoven a thickness of plastic.
To put it on like a slip there is a simple solution, just make a self-adhesive fastener that is the height of the disposable diaper, and thanks to the elastic sides, the disposable diaper will always be well adjusted.
To allow the disposable diaper to breathe, simply add a piece of foam (made of neutral material) between the nonwoven and the plastic (respecting the design, writing just above).
To avoid odors leaks, the solution is since the disposable diaper is now completely waterproof, just add a few things on the inner side that allows air to pass but not moisture or odors, this is where the charcoal filter is a very good solution.
This design does not need leakage barriers.
The product should not be too thick for that there is a simple solution put more SAP, and put the least possible cellulose, cellulose is a rather expensive material and in addition it is not very compressible, replace most of the cellulose with semi hard foam (always a neutral material) it allows to make very absorbent products, but do not take of space in transport, which are also very light, example when the package is new we could at least 3 pack of 10 disposable diaper, to have the equivalent in size of a package of Rearz, And yet we would double in SAP (double ISO absorption), using it we do not make a big difference if it is no embarrassment guaranteed.
My solution has positive and negative of course:
The positive:
no need to soak in this disposable diaper,
it respects the skin,
and the intimate parts,
no odors, more leaks,
a simpler cleaning,
a disposable diaper adjusted to the body,
the skin breathes,
costs less in transport,
takes much less space for storage as the package is new,
absorbs more than you can ever need (in normal use (maximum 8H days, 12H night (it is always advisable if possible not to exceed 6 hours of use))) You can even use it by spanking "the pear tree" there will be no leaks,
No more skin problem related to soaking in urine and feces.
The product has a greater chance of being well Seen by the general public, and eventually to be adopted.
The negative:
To guarantee a total waterproofness there is only one solution (to my knowledge) it consists of using a soft and neutral plastic disc to stick on the skin with a glue Already apply which is neutral as well obviously, this disc this place around the different "Hole" I think it's quite understandable
and a kind of very flexible plastic funnel, covered with non-woven fabric, stick it to the plastic circle glued to the skin, which guarantees a complete waterproofness.
The negative is it may take a little longer to put, when it's the first time.
The others are more negative points for ABDL only, the product is not extremely thick, the product only one fastener on each side, you do not feel like wearing a disposable diaper (since you are no longer in contact with urine etc.)
I wait for your reactions on the subject if you find it's interesting idea or not (this product would be with current technologies achievable) I would like to have so much reaction of people incontinent, that AB / TB / DL.
