Bumpers TRIZ Cases

A heterophasic propylene copolymer blend with an ethylene-based elastomer helps bumper materials balance low shrinkage, high gloss, and impact resistance.

A fragile bridge lets the sensor mounting plate detach in a frontal crash, shielding front sensors behind the bumper reinforcement.

A nested inner-outer member layout reinforces collision loads, suppresses buckling, and cuts material cost in vehicle underrun protectors.

Vertically moveable guards and bumper plates deploy from under the vehicle to block door strikes, carts, and other impacts automatically.

Separated central flanges in an extruded hollow bumper cross member improve impact stress absorption and bending stiffness without added weight.

A multi-stage bumper module combines deformable chambers and shear-thickening fluid to adapt to impact force and improve frontal energy dissipation.

A segmented bumper absorber uses small and large reaction sections to deflect impact outward while increasing collision energy absorption.

A flush closure element and forward protective element form an air duct that cuts swirling, lowers drag, and preserves low-speed impact protection.

A metal-resin bumper structure adds body-side ribs to stay rigid under light loads and deform under heavy impact while transferring energy to crush boxes.

Quick-release pivot pins and locking pins let a truck brush guard mount securely to the frame without multiple corroded fasteners.

A hollow crash extension with a bending flange absorbs small-overlap impact energy while limiting force transfer to the vehicle body.

Hard plates in a hybrid bumper energy absorber spread towing-ring loads while preserving crash energy absorption and side member protection.

A tapered reinforcing plate stiffens the bumper center while guiding arc-shaped deformation to absorb crash energy without buckling.

Chamfered or radiused crash box corners spread impact stress, improve weld quality, and keep the bumper cross member attached in central crashes.

A polypropylene homopolymer with 5-20 mm fiber reinforcement enables injection-molded rear bumper beams with low-speed crash strength and lower cost.

Metal beam extensions and resin ribs enable controlled buckling and rib breakage, improving impact energy absorption without adding bumper weight.

Crumpling sleeves and projecting members absorb and deflect impact forces while enabling one reinforcement assembly across vehicle platforms.

An extruded hollow connector links upper and lower bumper beams to improve energy absorption and block intrusion in car-to-car crashes.

Internal ribs and transverse branches in a bumper beam insert improve crash energy absorption while simplifying bonding and assembly.

An internal longitudinal guide controls folding in a hollow crash member, limiting buckling and raising impact energy absorption.

Controlled breakage between trunk and branch sections helps a bumper absorber absorb impact energy without raising pedestrian reaction force.

A non-matching outer beam and M-shaped reinforcement cut tolerance demands while improving crash energy absorption without cracking.

Oblique bumper crossmember ends engage the wheel and suspension to spread offset crash loads and limit passenger compartment intrusion.

A vertical hollow profile at the bumper end enlarges wheel contact and absorbs crash energy to prevent penetration and stabilize impact loading.

An obliquely downward ring-end crossmember spreads crash loads through the wheel and sill to reduce peak forces and deformation.

Distributed energy absorption between the bumper beam and crash box limits low-speed intrusion and reduces vehicle damage and repair costs.

A spaced interior rib and aligned hidden fastener openings keep plastic vehicle body panels smooth while avoiding sink marks on Class A surfaces.

A pivoting bracket and lobe frame keep an RV bumper end cap from falling out while allowing quick removal for sewer hose access.
