I have been looking at drawings and pictures of the inflatable prostheses and wonder if the pump could be built into an articulated RTE (rear tip extender) so that the action of foreplay and coitus would operate the pump to inflate the prosthesis.
In this way, the erection would grow gradually and emulate a natural erection. A pressure relief valve would keep over-inflation from happening.
I believe this could be easily done with some modification of the RTE and a deflation valve built into the RTE (if it can be reached by the owner's hand at the base of the penis) or in the scrotum (much smaller and unobtrusive than the current pumps and valves).
Combining the left and right RTEs into a single piece (if that is possible) would make the engineering pretty simple and almost all the tubing would be solid-cast into galleries and valves inside the solid part of the unit, ALL of the high-pressure parts would be INSIDE the solid part of the unit, thus protected from most damage. Only the (single) tube communicating to/from the reservoir would be outside the unit if the deflation valve were able to be cast into the RTE. Otherwise it would be in a short loop in the scrotum.
I have a rough drawing if anyone wants to have a look. The drawing shows a circular cross-section. This shape would not be possible, but changing it to an ellipse was more than I had time for.

The red bulbs are the inflation pump. Three so that axial movement or rocking movement in any direction will cause pumping
The gray is solid material
Six one-way valves ensure flow through the pump bulbs is always INTO the inflatable parts Only four are shown
The big circle in the center (blue/orange) is the release valve. Always open until erection is desired, then you toggle it closed. It may also be thought of as the deflation valve or the inflation lock valve). It is shown in a central location for simplicity but could be anywhere in the body of the RTE on the surface, maybe, if that is convenient or, if necessary, in the scrotum.
The unit is always "on" and fluid (saline) is permitted to flow through the bullbs into the inflatables and back into the reservoir, but if desired, a couple more valves could be used to lock out all flow once deflation is effected. Auto-inflation a thing of the past, even if the reservoir is squeezed.
The tubing back to the reservoir and the reservoir is shown in blue. This tubing is ALWAYS low-pressure, reducing chance of leakage failure.
The orange, of course is the pathway for the fluid to enter the inflatables.
The green, yellow and purple bridging the gap at the articulation is a flexible sleeve/tube which is to stabilize the articulation joint This is potentially a point of wear.
The pressure relief valve (If one is necessary) that prevents over-inflation is not shown
The diagram to the far right is a view of how the inflation and deflation galleries would be cast into the upper base unit. It may be necessary to make this part with 3-D printing or casting the unit in pieces before assembling them permanently to a single piece.
If the center valve is open, the blue and orange galleries communicate with one another, and the reservoir, thus no unintended inflation even if the three bulbs are pumping. Close that deflation valve and no drainage through the orange gallery occurs because the valve is closed. No drainage/deflation flows through the blue gallery because the one-way valves block that direction of flow.
