Penis Implants TRIZ Cases

A valve block with movable control members separates flow control from the main pathway, improving penile prosthesis inflation and deflation response.

Pressure sensing and piezoelectric pump control automatically deflate an implantable inflatable member to prevent misuse and unsafe overpressure.

A keyed rear tip extender adjusts penile implant length while resisting detachment through a rotating paddle-and-cavity connection.

A plunger-and-cam control with articulating and locking members reduces effort when switching a penile implant between curved and linear states.

Coordinated piezo pumps and valves use phase-offset timing and pressure sensing to stabilize implant inflation, deflation, and pressurization.

See how a spool-controlled five-port valve and check valves simplify inflation and deflation while reducing patient pumping effort.

A tactile pump bulb structure helps penile prosthesis users orient the assembly, prevent slipping, and locate the deflation actuator.

Uneven engagement forces can cause detachment; balanced locking teeth and rings improve rear tip extender retention.

This case uses a movable push valve and fluid bypass to prevent collapsed pump bulb entrapment during prosthesis deflation.

Segmented implant surface structure prevents fibrotic tissue bridging, maintaining functional integrity and natural erection angle.

Segmented inflatable member uses smooth and undulated chambers to lower inflation pressure while maintaining a natural tubular shape when deflated.

Segmenting the pump into two bulbs distributes fluid transfer, reducing manual force and sequential squeezes required for inflation.

Hermetic partitions isolate electronics from fluidics to prevent leakage while enabling precise pressure control.

Strut-based pelvic anchor secures neophallus implants without bone screws, reducing infection risk and migration.

Segmented porous mesh implant corrects curvature while promoting tissue ingrowth, reducing recovery time and revision risk.

Segmenting the pump bulb into convex lobes resolves dexterity trade-offs by improving grip reliability.

Movable connector portions on a distal portion align tubular members, resolving the trade-off between connection ease and device complexity.

A penile prosthetic insert features a longitudinal channel that maintains structural integrity during erection transitions.

Shear stress on dilatant liquid increases viscosity, eliminating repetitive pumping for erection maintenance.

Symmetrical valve guides constrain the poppet motion path within a fluid transfer pump assembly to reduce mechanical oscillation.

An inflatable bladder expands radially to form the base exterior of a penile prosthetic implant.

Segmented cylinder design with internal tensile support members reduces fluid volume and pumping effort while maintaining structural rigidity.

A segmented inflatable cylinder uses elongate members within a lumen to facilitate fluid transfer and reduce manual inflation effort.

A nested multi-balloon brachytherapy device uses a spacer balloon to modulate radiation dose distribution, reducing toxicity to surrounding brain tissue.

A penile prosthetic deflation assembly features a recessed activation surface for easy palpation through tissue layers.

A reversible flow pump assembly transfers fluid between a reservoir and an inflatable member using check valves.

Adapter with engagement lips secures rear tip extenders on lubricious hydrophilic-coated cylinders, preventing separation during implantation.

An inflatable penile bladder contains an internal insertion tool to provide column strength during surgical placement.

Single implant merges reservoir and pump via peristaltic tubing to reduce skin trauma from separate abdominal and scrotal devices.

Springless refill valve assembly uses fluid dynamic forces to drive valve movement, reducing refill time and inflation effort in inflatable penile prostheses.

Composite reinforcement strands reduce inflation pressure requirements, enabling faster device operation with fewer pump activations.

An electronic pump assembly automates fluid transfer between a reservoir and inflatable member, replacing manual pumping to reduce user effort.
