Engine Seals TRIZ Cases

Claw elements on the spring element interlock with the seal body, eliminating tool wear and fluff formation from machining retaining lugs.

An inwardly protruding plate end seals overlapping sections in a roll-formed door sash, eliminating water stagnation gaps that cause rust.

Ammonium polyphosphate and expandable graphite deliver halogen-free flame retardancy, resolving the trade-off between fire safety and environmental toxicity.

Annular backup device with a scarf cut expands to close clearance gaps and engage seal rings in blind glands.

Controlled austenite microstructure prevents surface roughening during processing, maintaining gas seal capability at 600 to 800°C.

A tapered segment seal assembly uses a central seal pin to occlude gaps between independently loading segments.

An integrated transport cover with a through-hole allows lubricant application without removal, eliminating cleaning steps.

Segmented weirs in a hydraulic seal trap retain oil at shutdown to prevent leakage while minimizing heat transfer during operation.

Resilient sealing member uses concentric ridges to distribute pressure and maintain fluid-tight integrity across multiple connection cycles.

Centrifugal rotating component generates positive pressure within a hybrid module housing to maintain internal sealing integrity.

A glass run channel assembly uses a pre-structured surface area on the extruded profile to increase grip within the molding tool during injection.

Expulsion ports direct lubricating fluids into annular channels, reducing frictional heat and extending operating life.

A glass run channel applies a solid material covering over a thinner sponge lateral wall connecting portion to prevent tearing while reducing weight.

Segmented rubber sealing profile accommodates vertical and horizontal sliding step movements, preventing deformation and noise during operation.

A shaft assembly uses a rigid component fixed to the sealing element to prevent extrusion during reciprocating motion.

Optimized back-up ring axial length ratio reduces compressive stress on elastomer seals, preventing cracking damage in 45,000 psi applications.

An oblique channel between race members houses a frustoconical ring member that reduces steering column noise and turning torque.

Embedded metal support with notches limits screw force on elastomer, ensuring reliable flange sealing.

A gasket with a stepped resin carrier integrates structural support directly into the sealing unit.

Nesting the radial magnet coupling inside the impeller balances thrust loads and exposes the canister to incoming fluid for effective cooling.

Extracting the piston rod segment outside the cylinder reduces weight and complexity while maintaining reliable barrier fluid management for LNG pumps.

Oppositely oblique sealing lips press radially onto the inner part, preventing dirt ingress and lubricant loss despite angular misalignment.

Segmenting the L-shaped baffle sleeve into flange and cylinder parts reduces onsite assembly complexity and material wastage.

A segmented sealing assembly uses compression elements to engage tapered tongues and interlacing beads for continuous perimeter sealing.

An applicator head uses magnetic attraction to position filler disks on smooth surfaces, reducing burn risk during melting.

Integrated seal members on molded parts eliminate vertical walls and manual alignment, simplifying sunroof installation.

A disc brake sealing device uses a bellows outer stiffening ring with a circumferential groove to engage caliper projections for axial fixation.
