Bodily Discharge Devices TRIZ Cases

A fluid collection device uses a dry adhesive region to attach securely to a user's garment.

A fluid collection sheath uses a porous material to absorb urine from the penis.

A fluid transfer assembly uses a pump to modulate pressure within a collection container, enabling automatic expulsion of urine.

A fluid collection assembly uses a securement body to limit movement relative to the urethral opening.

Segmenting the ostomy adhesive wafer into zones with varying thickness provides a tactile grip and notch that ease removal while maintaining central thinness.

Distributed suction apertures along a serpentine conduit prevent pooling and leaks, reducing infection risk.

An asymmetric slope design minimizes mid-wear leaks and messy removal in women with anatomical variations.

A fluid collection device uses a permeable body to wick liquid into an impermeable chamber.

An absorbent pouch with a zipper and O ring collects urine externally, eliminating internal catheter infections.

A hinged sleeve and elastic band secure a condom catheter via dry friction, preventing slippage on flaccid tissue without impairing blood flow.

A urination assistance apparatus uses a telescopic tube and rotating joint to position the discharge funnel for user comfort.

Multi-durometer materials in a menstrual device improve comfort and leak protection by balancing stiffness and flexibility.

Vertical nonwoven fibers capture and move bodily fluids rapidly, preventing leakage and skin degradation during prolonged use.

Segmented container design prevents spillage and reduces emptying time for truck drivers on long trips.

Curved internal walls divert solid waste from the filter while gas flows through, preventing clogging without complex barriers.

Applicator plunger deploys folded menstrual collection device via projections, resolving insertion discomfort.

An elongated cross-section tube design enhances flexibility and fluid flow efficiency.
