Superstructure Subunits TRIZ Cases

Internal coupling pieces attach the bumper to a cross-member and wings, reducing hole alignment effort and improving assembly ergonomics.

An elastically deformable one-piece vehicle cover strip removes visible trim joints while enabling precise alignment and secure attachment.

A buoyant gate lets sill fluid drain on land, then seals during deep water immersion to block ingress and reduce internal corrosion.

A reusable carrier with expandable inserts adapts insulation to different vehicle cavities while cutting custom tooling and production cost.

A water-blocking wall and guided floor slopes redirect drainage away from pickup power electronics while preventing stagnation and cabin ingress.

Vacuum between the carrier and décor layer forms visible trim protrusions without actuators, improving reliability and simplifying vehicle interior assembly.

A hollow cast aluminum shock absorber cup uses tangent arms and an internal opening to route power networks while keeping suspension attachment robust.

Arc-shaped groove and boss locking keeps a flexible vehicle trim panel hatch securely closed during deformation and prevents radial release.

A movable roof cleaning nozzle retracts outside the sensor view, improving see-through area cleaning while reducing blind areas and wind noise.

A bolt-on double-shear mount spreads suspension loads across two shear planes to reduce bolt shearing and preserve alignment under extreme travel.

A roof-integrated environment sensor rotates between resting and operating positions to save space, protect the sensor, and simplify assembly.

A two-piece wheel fairing cuts aerodynamic drag while preserving downforce, low weight, and easy tire mounting on electric vehicles.

A gasketed pillar garnish and cowl-mounted fender cover minimize hood-to-A-pillar gap, cutting wind noise while preserving appearance.

Flexible entry clips and a divided housing let hidden trim retainers insert easily while preserving door panel fastening strength.

A spring-loaded intermediate pivot and dual-arm linkage let vehicle doors open independently in tight spaces without sliding-door sill penalties.

A planar upper door and cylindrical lower door improve bumper-integrated air flap motion while reducing leakage that degrades cooling modules.

A formed hard-plastic shell locks into the door pull and sill to protect interior panels without adhesives, fasteners, or surface damage.

Support brackets linking the reinforcement member and apron bracket limit bumper movement to prevent grille cracking and maintain alignment.

A metal insert with an overmolded thermoplastic rib spreads strut loads to reduce creep and extend thermoplastic vehicle component life.

A thermocompressed PET, natural-fiber, and polypropylene blend improves under-engine sound absorption while resisting gravel damage and cost growth.

Openings in a first trim layer let a second layer show through, creating smoother visual transitions between different surface appearances.

Continuous-fiber cover layers and an integrally molded plastic core with ribs improve crash strength while simplifying vehicle bumper production.

Controlling aldehydes to 0.1 ppm or less cuts polyolefin foam odor in hot weather while preserving strength, flexibility, and heat resistance.

Blocking walls and a drainage chamber separate rainwater from fast cowl airflow, supplying drier cabin air in a compact vehicle layout.

An inclined rail garnish wall follows the hatchback door path to reduce visible gap while preventing contact through opening and closing.

Sandwiched crossbar brackets balance deformation box loading and raise front-end lateral rigidity in low-overlap vehicle impacts.

A transverse-moving projection locks into a recess to hold vehicle modules under high force without added screws or complex assembly.

A threshold-based wheel cover holder stays neutral at small steering angles and turns at larger angles to cut wheel-opening drag.

Curved D-pillar and rear spoiler garnish surfaces create a labyrinth gap that slows venting airflow and cuts rear wind noise.

A biased retention clip engages a wheel notch to secure the cover while simplifying installation and reducing accidental detachment.

A hard-soft seal spans the side door edge to absorb panel tolerances, block dirt and liquid, and prevent paint flaking and corrosion.

A segmented door reinforcement and foam damper absorb side-impact energy and help keep the door supported on the side sill.

Aromatic polyester-based TPU in a PC/ABS blend improves hydrolytic stability while preserving high flow and low-temperature ductility.

A door frame extending into the rear wheel well enables wheelchair lift access with fewer body changes while preserving wheel clearance and safety.

A front crossmember and bumper rail decouple bumper and ranging sensor alignment from body-in-white variation, improving fit and sensor protection.

By using the trunk as part of the washer tank, this structure cuts front-end weight impact, saves space, and helps stabilize ride comfort.
