Respiratory Apparatus TRIZ Cases

Dual connector points let SCBA users swap hose and bypass valve positions for easier dominant-hand control and faster response.

An integrated alerting device and refill passage simplify SCBA pressure reduction while reducing external plumbing and system weight.

A passage beyond the sealing interface pressurizes the balancing chamber for stable closing under changing breathing pressures.

This case uses snug, deep-projecting nasal inserts to seal both nostrils without excessive external force during dives.

A diving buoyancy control valve integrates manual reset functions into existing inflation and deflation mechanisms.

Spring-loaded nosepieces in a second stage regulator automatically seal around the nose, reducing breathing effort during underwater escape.

Manual inflation of an adapter body distributes pressure evenly, resolving the trade-off between sealing fit and user comfort.

Actuator triggers jacket inflation and weight dumping when breathing regulator airflow ceases, preventing drowning during incapacitation.

A lung demand regulator uses a cam element and follower to lock gas flow when disconnected from the face mask.

Single control mechanism adjusts spring pre-stress and orifice passage to resolve complexity trade-offs in diver breathing comfort.

Peroxide decomposition in ionic liquids releases breathable oxygen at low temperatures, avoiding toxic byproducts and freezing issues.

Segmenting the battery zone with a compressed intermediary layer prevents water and dust intrusion into the internal chamber.

A breathing apparatus mouthpiece uses a flexible diaphragm to switch between closed and open circuit modes.

A stiff cup-shaped casing and curved discoidal lid compress loose filter material into a uniform bed without additional support structures.

Chemical bonding of a thermoset elastomeric seal to a rigid attachment component eliminates separate gaskets and reduces assembly complexity.
