Engine Seals TRIZ Cases

A machining device uses independently movable retaining elements to form a V-shaped receiving area for secure gripping.

A labyrinth seal stator cavity containing a heat transfer medium cools or heats process fluid before it reaches the dry gas seal.

A composite sealing unit integrates guide elements and sealing components to simplify installation.

Segmented mounting base with J-shaped and V-shaped lips prevents disconnection during panel movement without increasing weight or complexity.

Segmented contact seals create a convoluted path that prevents dust contamination and reduces maintenance downtime in conveyor rollers.

Replacing Teflon U-cups with O-rings repositions the sealing area, enabling reuse of fret-damaged shaft sleeves without modifying the cartridge.

Reinforcing plates fix the partition plate to gland seal walls, preventing deformation under oil pressure without pre-formed grooves.

A metal chevron axial seal assembly uses PEEK and nickel components to maintain contact with cylindrical surfaces under high pressure.

Segmented cylindrical converters reduce material stresses and parasitic heat transfer while maintaining high energy transformation efficiency.

A seal member taking-out device uses a movable cylinder to convey stacked seals along a shaft.

Spring steel retaining clips join gear housing components while a narrow support region compresses an annular seal for uniform sealing.

A linear piston engine uses a curved joint seal to accommodate connecting rod movement within the cylinder.

Pressure indicator tape adhered to vehicle door seals reveals contact pressure distribution through color intensity changes upon closure.

A tetrahedral amorphous carbon layer coats the shaft sleeve to enhance axial mobility of the secondary seal O-ring.

Mechanical locking parts engage weather strip grooves to resolve assembly difficulties while maintaining holding force.

Segmented garnish and seal members protect the pinch sensor from occupant damage while maintaining obstruction detection.

A backup ring assembly balances radial pressure to maintain a stable extrusion gap in dynamic seals.

A weather strip tip projection portion deforms to contact vehicle panels.

Segmented shoes on an offset base reduce radial height and weight while maintaining sealing reliability.

Overlapped contact seal portions isolate robot joint gaps to retain lubricant and block external dust.

A vehicle door uses a coupler to adjust section positions relative to each other.

A seal structure integrates a resin film with a rubber gasket to enhance shape retention without increasing reaction force.

A sealing sleeve with a bellows portion prevents water ingress and galvanic corrosion in marine actuators.

Optimizing ring cap rubber hardness reduces pressing force below 500 grams, suppressing stick-slip noise while maintaining sealing reliability.

A mid-turbine frame buffer system uses pressurized air and carbon contact seals to maintain bearing compartment pressure.

Heat treatment raises the glass transition point of a thermoplastic polyurethane buffer ring to preserve compression set resistance at 120°C.

Offset peaks with inward constrictions reduce stress fatigue and prevent oil canning in metal bellows.

A composite seal uses a metal member to reflect ultraviolet radiation away from an elastic sealing component.

Ethylene propylene diene rubber covers sealing member ends to prevent low-temperature cracking while maintaining gas-tightness.

Varying-sized slots tailor airflow to create a stable pressure barrier, reducing cooling air consumption while preventing hot core gas intrusion.

A unitized bi-directional seal assembly connects opposing annular seals via a locking ring to ensure structural integrity.
