Doors TRIZ Cases

Two rail-guided flaps keep one hatch section closed if the other opens, limiting vehicle bulk and preventing clearance accidents in motion.

An integrated composite reinforcement replaces multiple door subcomponents to cut weight while maintaining side and frontal impact resistance.

A plastic-metal door panel uses quadrangle reinforcement to raise rigidity while cutting mold cost and production time for varied vehicle doors.

A separately formed lower-member projection improves alignment, welding, and sealing in vehicle door frames while avoiding bending damage.

A bracketed reinforcing member keeps a vehicle door outer panel rigid while avoiding surface waviness and reducing dents during washing or waxing.

A jig-fixed anchor plate position standardizes sliding side door rail alignment, reducing manual adjustment and improving production consistency.

Segmented inner reinforcement supports complex vehicle panels, limiting dents under pressing while avoiding outer-surface unevenness.

Multiple pivot members guide a vehicle side door to preserve interior access, driver-door clearance, and a flush closed appearance.

A two-part pickup rear door uses slides, telescopic jacks, and damping to enable vertical opening where rear clearance is limited.

Shouldered screws and molded bosses secure liftgate brackets to composite inner panels, cutting assembly time while avoiding visible sink marks.

A hinged-fastened and slidably coupled door panel structure absorbs thermal expansion between plastic and metal panels to prevent body interference.

Injection-molded stiffening turns the organosheet door carrier into a load-bearing sill reinforcement, reducing weight and cost.

A slotted vibration absorber slides onto a pre-installed door fastener, simplifying fit-up while maintaining secure impact retention.

A two-part framed door bodyshell shifts the sealing flange below the window line to hide the seal, avoid frame interference, and block dirt ingress.

By spacing the weld away from upper-frame edges, this door frame avoids component interference and reduces cutting or polishing work.

Gas-swollen hollow door beams replace lapped steel plates to cut weight while improving side-impact energy absorption and deformation resistance.

Magnetic attachment, straps, and hinge-post supports let a collapsible vehicle door install in seconds without vehicle modification or tools.

A tube-shaped support member replaces hat-shaped beam supports to absorb side impact loads more evenly and preserve panel integrity.

A frame-and-truss reinforcement overlaps the door panel boundary to transfer inward loads and suppress local deformation without sacrificing styling.

An adjustable liftgate housing repositions OEM cameras and proximity sensors to preserve rearview visibility after tailgate removal.

A welded bracket between the door beam and inner panel spreads side-impact loads, boosts rigidity, and helps prevent door opening in crashes.

A sealed support plate hides tailgate lighting in a dry zone while the removable outer skin preserves styling and simplifies service.

An adhesive-filled rim reinforcement strengthens thin vehicle door panel openings while avoiding visible read-through on the opposite surface.

A modular tarpaulin tensioning device adapts to raised or lowered roofs, reducing side-sheet flapping, drag, and handling effort.

A curved door beam with a crush box redirects side collision loads into the vehicle body frame, improving absorption while reducing center pillar impact.

An auxiliary side reinforcement supports the exterior opening control support, limiting side-impact deformation that could trigger unintended door opening.

A hinge-mounted privacy panel with fabric sections, braces, and vents shields split-liftgate cargo areas from view and wind.

A mounted garnish bridges sharp corner geometry so one front door fits both two-door and four-door cabs without panel forming failure.

Rigid interlocking panels slide fore-aft to open trailer sides for loading while preserving security and reducing wind-related opening hazards.

Bracket protrusions lock into guide rail recessions during roof crush to keep a pillarless vehicle door attached and distribute loads.

A pivoting-door retainer and sliding-door extension prevent untimely opening during transverse impact in pillarless vehicle body sides.

Elastic flaps and shape-coupled module profiles simplify industrial vehicle door assembly while enabling adjustable width and lower production cost.

An outer-overlap cover edge seals the inner panel opening to block water and moisture entry while simplifying vehicle door assembly.

Two independently rotating trunk panels improve cargo loading flexibility, reduce clearance needs, and maintain secure sealing in closed use.

A collapsible Jeep door frame uses retractable fabric and clear panels to balance easy removal, weather protection, visibility, and low weight.

A removable intrusion-beam module converts a conventional vehicle door to a skeleton door while preserving protection and in-vehicle storage.

A deployable two-member assembly fills the B-pillar gap during impact, boosting body rigidity without blocking vehicle entry and exit.
