Bodily Discharge Devices TRIZ Cases
- Menstrual Cup Slit Venting for Low-Force Extraction
A longitudinal slit opens an air channel during stem pulling, breaking cup vacuum to ease removal while avoiding complex stem structures.
- External Catheter Layout for Simultaneous Urine and Feces Suction
Separate urine and feces chambers with targeted apertures and suction paths improve collection during diarrhea while limiting fluid ejection.
- Female Waste Capture Funnel With Insert for Clean Urine Collection
A contoured funnel, adjustable skirt, and wicking insert improve female urine capture in low gravity while reducing backsplash, mess, and cross-contamination.
- Urethral Cup Catheter Structure for Vacuum-Assisted Urine Removal
A urethral cup and permeable chamber structure improves female external urine collection by combining comfortable fit with vacuum-assisted removal.
- Vacuum Urine Collection Chamber for Accurate Output Measurement
A vacuum chamber and plunger valve clear retained urine from tubing to improve output measurement accuracy and prevent backflow.
- Adhesive Fecal Collection Interface for Continuous Drainage
An adhesive skin interface, drainage conduit, and one-way valve enable continuous feces collection with easier replacement and lower pressure sore risk.
- Fluid Collection Assembly With Movement-Stable Leak Control
Porous wicking and flexible positioning features help a fluid collection assembly reduce leakage while allowing more comfortable movement.
- Adhesive Sump Barrier for Hygienic Urine Collection
A body-mounted sump barrier uses porous media and adhesion to collect urine with less leakage, discomfort, and infection risk.
- Excreta Collection Cleaning Assembly for Immersion Disinfection
A sealed inner chamber lets the spray nozzle form disinfectant solution for easier immersion disinfection of the excreta recess.
- Expandable Excretion Cup Sealing for Posture-Change Leakage
A fluid-expanded sealing body keeps the excretion cup in close contact during posture changes, preventing waste and rinse-water leakage.
- Urine Collection Sleeve Pleat Structure for Adaptive Body Fit
Pleated water-permeable and waterproof sleeve layers create a shapeable urine collection pocket that improves fit, dryness, and leak control.
- Urine Collection Indicators for Overflow, Kink, and Pressure Control
Volume, flow, and pressure indicators help a wearable urine collection setup prevent overfilling, tube kinking, and poor suction.
- Wearable Urine Collector With Check Valve for Backflow Control
A constricted tubular collector and check valve block urine backflow and leakage while keeping wearable collection comfortable during sitting or lying down.
- Garment-Based Urine Collection With Urethral Positioning and Wicking
A wearable crotch-mounted collector uses urethral positioning, a fluid barrier, and capillary wicking to keep users dry without invasive catheters.
- Shape-Memory Fluid Collection Assembly for Leak-Safe Anatomical Fit
Shape memory material helps an external fluid collection assembly conform to patient anatomy, reducing leaks, discomfort, and infection risk.
- External Urine Collection Sleeve-Cup Assembly for Urethral Access
A detachable sleeve and cup improve urine collection while preserving urethral access and reducing discomfort and infection risk.
- Condom Catheter Chamber Structure to Prevent Leakage and Skin Damage
A porous chamber and collapsible side wall collect and direct urine away from skin to reduce leakage, pooling, and discomfort.
- Fluid Collection Barrier With Adhesive Base to Prevent Slippage
A localized adhesive base secures the collection barrier in the gluteal cleft, reducing slippage while improving urine capture and comfort.
- Multi-Region Fluid Collection Structure for Gravity-Independent Drainage
Multiple angled collection regions and selectable conduits keep fluid draining effectively even when the collection device is repositioned.
- External Catheter Flange Securing to Reduce Leakage and Skin Irritation
Adhesive tabs moved from the penile shaft to the abdomen improve external catheter retention while reducing leakage, constriction, and skin irritation.
- Wearable Urinary Reservoir Seal for Female Anatomy Mobility
A flexible lip seal and siphon tubes let a wearable urinary reservoir collect urine in any body position without internal catheters.
