Colostomy TRIZ Cases

A drainable ostomy pouch uses a pocket to receive the folded drain chute for secure retention.

Resilient foam in the fluid chamber dynamically adjusts volume to manage stoma movement and prevent leakage.

A waterproof cover protects ostomy appliances using a zipper mechanism and adhesive layers.

Segmented breathable material and adjustable buckles enable end-user assembly of custom-fit belts, resolving manufacturing inefficiencies from standard sizes.

Citric acid and zinc ricinoleate in a hydrogel extend pouch usability by neutralizing odors over extended periods without frequent changes.

Monitor device tracks adhesive moisture propagation via electrodes, preventing leakage and skin damage.

Alternating high and low density zones create visual contrast for correct positioning while periodic peel force peaks prevent unintended detachment.

Segmenting the seal from the body side member extends adhesive wear time while preventing skin irritation from exudate exposure.

Capacitive and temperature sensors detect bag fill and skin inflammation to prevent leakage and irritation.
