Engine Seals TRIZ Cases

An anti-fretting agent and seal member keep the wheel hub spigot fit protected, reducing wear and improving wheel drive durability.

A water-repellent gap placement portion helps stop water buildup and ice bonding between a vehicle lid and body in low temperatures.

A resiliently mounted magnetic fluid shaft seal absorbs runout and angle errors, reducing bearing loads and extending seal life in pumps and motors.

A softer connecting portion and harder seal and base improve vibration transfer, cutting road and wind noise without seal protrusion.

A corrugated thermoplastic seal replaces metal reinforcement to stay flexible, recyclable, and securely clamped on curved vehicle rebates.

UV-curable gasket molding suppresses air bubbles in overlapping dispense paths, improving thickness uniformity and sealability for fuel cell parts.

Cover portions and side-frame protrusions reinforce sunroof seam intersections to prevent leakage where front and rear windows meet.

An installation groove, stopper, and TPV joint keep the door inner belt aligned to the frame, blocking noise and air leakage.

A flange inserted into the door-body axial gap interrupts bypass airflow, deflects splash debris, and keeps vehicle body surfaces cleaner.

Position-based inflation and release of an RV slide-out seal improves weather sealing while reducing seal damage from continuous pressure.

Chemically exfoliated vermiculite with insoluble carbonate improves SOFC and SOEC gasket sealing while reducing high-temperature corrosion.

A two-pane vehicle camera assembly preserves a privacy-glass look while using a higher-transmission pane and garnish concealment for imaging.

An integrated end plug in the sunroof frame lets the waterproof strip slide into a tubular receiving space, avoiding hot welding and extra positioning parts.

A detachable rotor bearing unit with integrated sealing and locking enables generator servicing without water ingress, corrosion, or full disassembly.

A folded sealing boot uses stop-shoulder abutment and eversion to save housing space, preserve push-rod stroke, and improve boot life.

A hard frame with soft coating simplifies demolding of motor vehicle window seals while preserving secure attachment, sealing, and appearance.

A fluoroelastomer-embedded metal ring and sleeve assembly helps wheel hub seals withstand 300°C and last over 4000 hours.

A liftable roof and rotating sealing doors close non-docking side gaps to keep the docked vehicle-building interior clean and quiet.

Multiple bellows and pressure-zone openings help a cab-to-module seal block water and dust while accommodating relative movement.

Temporary seals protect stator coolant passages during VPI, preventing resin blockage and debris while preserving heat transfer.

A reflected-light door joint assembly boosts visibility on curved transport vehicle leaves while protecting LEDs and simplifying installation.

A single applique rigidly mounted at the B-pillar cuts visible window gaps while maintaining flush door surfaces and reliable sealing.

A vent channel in the seal mounting groove relieves protective-gas pressure, preventing seal lift and leakage when opening a high-pressure chamber.

Temporary seals protect stator coolant passages during vacuum pressure impregnation, preventing resin blockage and debris ingress.

Foam sheaths seal gaps between an exterior mirror wire harness and gasket to cut wind noise, block intrusion, and keep the assembly stable.

Rain-aware threshold switching uses impedance and resistance sensing to cut false door pinch alarms while preserving safe reopening.

Separate external resistance sensing and internal impedance sensing in door weather strips improve pinch detection on both sides during closure.

A vent channel releases protective gas from the seal groove, keeping the sealing unit seated and preventing leakage when the chamber opens.

A press-fit seal element and preloaded retaining ring legs keep valve seals centered, fixed, and responsive to pressure changes.

An integrated sealing lip in the wheel bearing sensor assembly blocks contaminants while simplifying assembly and supporting wheel speed sensing.

Surface-treated seal lips and a maze slinger cut rotor friction, wear, and contaminant ingress in harsh in-wheel motor conditions.

Preheating the cover strip matches shrinkage during injection molding, preventing cracks and longitudinal slip in window-channel seals.

A deformable back-up ring changes radial shape with fluid pressure to minimize clearance gaps, prevent leakage, and protect O-rings.

Positioning the RF electrode inside the attraction electrode helps cut wafer edge heating and improve in-plane temperature uniformity during etching.

Embedding the attraction electrode in the chuck protrusion improves cooling, lowers thermal resistance, and protects the joining layer from plasma.

A perpendicular stop and trim cutout lock vehicle window-joint trim in place, preventing age-related sliding and opening interference.

An inflatable sealing tube maintains airtight vehicle-building docking during roof movement while reducing weather strip wear, dust, and noise.

Metal-to-metal connectors and detent engagement improve mount attachment strength, prevent dislodgment, and protect the liquid chamber from leakage.

A silane-like surface treatment film and OH/CH3 sealant strengthen chassis adhesion to keep electronic control housings airtight under salt damage.

An elastic gasket lets a telescoping surveillance mast pass through a vehicle roof opening while keeping equipment hidden and the cabin sealed.

A two-part closing device radially displaces sealant to seal extruded aluminum profile ends without screws or rivets, preventing media leaks.
