Understructures TRIZ Cases

A widened curved top plate lets an open-section structural component keep high reaction force under load without closed-section welding.

Elastic suspension isolates engine vibration while a central rear crash box improves impact energy absorption without adding vehicle length or weight.

A stowable trailer enclosure creates a sheltered workspace for fitting tire chains in snow and ice, improving driver safety and comfort.

Sliding cross beams let LiDAR sensors be repositioned on the tractor frame for more accurate semi-trailer angle and blind spot detection.

A nested battery enclosure keeps high-voltage cables short and protected while preserving familiar fire truck controls and fleet-ready operation.

A damper nested in a U-shaped chassis cross-member shifts floor-panel resonance to cut vehicle noise and vibration at 160-200 Hz.

Selective clutch decoupling lets inner truck wheels free-rotate during lateral motion, cutting friction and wear without adding wheel motors.

A 45° square-tube frame lets loading bridges and the driving assembly shift for different timber bundles while reducing trailer weight and noise.

Front and rear torsion axle assemblies use asymmetric quadrilateral geometry to reduce shock transfer while preserving traction, steering, and stability.

A narrowed front side and closed top contour reduce peak weld tension, extending chassis-beam joint life while cutting bracket weight.

A segmented 3D front body framework disperses frontal crash loads to protect the cabin and battery pack in full-wrap and small-overlap impacts.

A one-piece sand-cast aluminum front body structure cuts part count, weight, and assembly steps while preserving vehicle body strength.

A segmented beam-and-axle height mechanism lowers the vehicle body further for loading while still raising clearance for rough roads.

A stepped receiving cavity locks a support flange inside a plastic fuel tank, avoiding sensitive welding while improving stiffness and durability.

Welded steel external and internal panels replace complex aluminum fastening to cut cost, reduce weight, and hold side sill rigidity in crashes.

A transverse reinforcing member between cross-member joints helps the rear side frame resist side-collision deformation and protect cabin space.

Detachable front and rear frame joints with local reinforcement improve EV chassis assembly strength while simplifying part replacement.

Spring-loaded flapper doors replace a fuel cap to keep the filler pipe sealed during refueling while reducing spills and manual handling.

Inclined main frame walls and a load-sharing bottom wall absorb side impact loads, avoiding larger cross members and extra case weight.

A double rib layout inside plastic vehicle tanks distributes axial, bending, and torsional loads while remaining compact and easy to weld.

A box-shaped front body frame links side members to transfer small overlap collision loads, boost rigidity, and limit A-pillar deformation.

Downward column members and a connecting brace stiffen the vehicle floor cross member while preserving cabin space and conduit routing.

A segmented undercover shields connectors from moisture while preserving moving-component clearance and electrical safety in the vehicle frame.

An outward side-frame and straight lower member improve offset collision load transfer, reducing lower-member bending failure and aiding weight reduction.

Interconnected side, suspension, and fender apron members form box structures that disperse front collision energy without sacrificing cabin space.

A plunger-shaft lock with a guarded indicator replaces reel pins, preventing pin loss and showing locked or unlocked status at a glance.

Detachable frame sections and wheel assemblies let one person quickly break down and reassemble a towable trailer for compact storage.

Removable cradle and hoist bracket assemblies use interchangeable bushings to avoid welding, cut alignment issues, and speed dump truck setup.

Snap-engaged support rods cut robot car body assembly time while preserving load-bearing strength through a hybrid snap-and-screw connection.

Ground-level gantry assembly lets crews build mirrored roof sections before hoisting, reducing rooftop labor, accident risk, and delays.

A hook-and-ridge bracket enables self-alignment, faster AGV-friendly docking, and secure vehicle equipment mounting under vibration.
