Female Contraceptives TRIZ Cases

An osmotic intra-orifice housing uses semipermeable membrane uptake to drive controlled drug release, increase loading flexibility, and avoid reuse.

A flexible intrauterine frame uses locking parts and a removal thread to pass the cervix with less discomfort and lower uterine penetration risk.

A sterilized placement tube constrains IUD rotation and string position to enable hygienic postpartum insertion with less trauma and easier retrieval.

A shape-memory IUD expands against the uterine wall to limit migration while enabling focal copper delivery with less exposure and insertion discomfort.

A grasper, camera, and guided home-use kit help patients secure IUD strings and remove the device safely when clinic access is limited.

Wireless electromagnetic charging lets an IUD monitor uterine conditions long term without an internal battery, reducing size and leakage risk.

A slider-controlled string lock keeps the intrauterine system stable during insertion, reducing misalignment, jamming, and string damage.

An expandable absorptive unit conforms to the vaginal cavity to remove retained semen from remote regions, helping reduce odor and infection risk.

Automatic string locking and slider control keep the IUS stable in the insertion tube, reducing misalignment, jamming, and damage.

A compressed-to-expanded absorptive unit conforms to vaginal anatomy to remove semen from remote regions and reduce odor.

A shaped tray and pivoting channels fold and hold IUD arms against the shaft, making insertion tube loading easier for providers.

An elastic holding element retracts into the IUD body for easier insertion, then expands against the uterine wall for secure fixation with less pain.

An expandable frame deploys an absorptive element to capture seminal fluid across the vaginal cavity and reduce odor from fluid persistence.

Short-term vaginal insertion uses a biocompatible body and exposed copper inlay to prevent pregnancy without hormonal exposure or long-term IUD complications.

A plunger-generated vacuum grasps and stabilizes the cervix during IUD insertion, reducing pain and trauma without a tenaculum.

A clamp, hypotube, and vacuum applicator control threaded IUD loading into the insertion device for automated knot tying.

A plunger-based intra-uterine device inserter uses a manually actuated friction contact surface to regulate protective tube sliding.

A removable fiducial marker implant extends to distribute markers along uterine tissue for precise 3D localization during radiosurgery.

Threaded stainless steel tube on frameless IUD suture provides echogenic marker for anchor visualization, reducing uterine perforation risk.

Flexible metal inner tube navigates uterine anatomy for precise intrauterine device placement, resolving blind insertion errors.

A force sensor between the handle and insertion tube provides visual feedback on applied pressure.

Segmented flexures with varying stiffness extend from a collapsed position to deployed, reducing sheath diameter and cervical injury risk during insertion.

An integrated catheter combines a compression balloon with a gripping barrier structure, reducing procedural complexity by eliminating multiple instruments.

A miniature HDR applicator system uses T-shaped wings to anchor within the uterus for precise radiation delivery.

Visual guidance tools enable safe self-insertion and removal of intrauterine devices, improving accessibility in underserved communities.

A pre-filled vaginal applicator uses a resilient piston and plunger to eject medication through a dispensing opening.

An elastic rod intrauterine device transforms into a closed loop via a thread locking mechanism to maintain stable positioning within the uterus.

Elongated cavity in the pusher distal end houses the IUD stem terminal part to transmit axial force reliably.

An overmouldable substrate uses an insertable mould assembly to form a medicament reservoir.

A vaginal therapeutic delivery device uses a non-absorbent tubular structure to dispense pharmaceuticals directly to the mucosa.

Segmented insertion tubes and a slider lock eliminate manual string handling to prevent device jamming during intrauterine system placement.

An intrauterine inserter uses a movable slider and flange to manage removal strings during device placement.

An intra uterine ball device employs a shape memory alloy member that transforms into a spherical configuration, preventing expulsion and mal-positioning.

A zinc-copper-manganese-gold alloy wire releases ions to provide contraceptive effectiveness.

An open-frame structure exposes the polymer matrix deposit surface to enable diffusion, eliminating complex membrane integrity issues during insertion.

Curved plunger tip surfaces guide intrauterine device insertion, preventing loop damage during misaligned placement.

Soft resilient coatings on the hook and plate prevent vaginal canal damage during estrogen ring removal.
