Doors TRIZ Cases
- Aluminum Extruded Door Beam Composition for SCC-Resistant Impact Absorption
A tuned 7000-series extruded alloy balances impact absorption, low beam weight, and SCC resistance through controlled Zn-Mg-Cu and Fe-phase chemistry.
- Convertible Truck Bed Cover With Sliding Pivot Panels
Sliding and pivoting top and side panels let a truck bed cover switch between tonneau and cap configurations with less removal effort.
- Vehicle Rear Gate Structure With Stiffening Plate Reinforcement
A stepped inner skeleton and overlapping stiffening plate raise rear gate rigidity while avoiding complex hat-shape forming of both panels.
- Laminated Door Service Hole Cover for Acoustic Sealing
A laminated door cover combines a sound-absorbing cushion layer and rigid insulating board to seal service holes with fewer parts and easier installation.
- Vehicle Door Hole Cover Structure for Clip Detachment Access
Guide walls and a protruded portion hold the clip while opening tool access, making vehicle door hole cover removal easier.
- Quadrant Cover Gutter Structure for A-Pillar Fluid Deflection
Integrated gutters on the quadrant cover divert rainwater and washer fluid away from the front door to preserve side mirror visibility.
- Vehicle Door Impact Pad Structure for Handle Deformation Reduction
An impact pad bridging the inner door access opening redirects impact loads away from the handle assembly to reduce deformation during crashes.
- Refrigerated Vehicle Sectional Door Rails Integrated Into Side Walls
Integrated side-wall guide rails widen the rear opening of refrigerated vehicle bodies while preserving insulation and a flush exterior.
- Vehicle Door Mirror Mount With Dampener for Rattle Reduction
A dampener between the mirror base bracket and door panel isolates vibration, reducing side mirror rattling and cabin noise.
- Convertible Truck Shell Roof for Weatherproof Tall-Item Access
A modular retractable truck shell roof protects cargo from weather while opening for easier access and taller item transport.
- Modular Vehicle Door Panel Sharing for Full and Half Doors
A shared lower door panel lets full and half vehicle doors use common knobs, latches, and hinges while cutting mold cost and preserving sealing.
- Commercial Vehicle Stanchion Locking with Rounded Retaining Contours
Rounded retaining contours lock a movable vehicle stanchion to the roof rail, preventing release under braking and heavy load forces.
- Composite Vehicle Beams With Mixed Fiber Layout for Crash Resistance
A two-beam composite layout combines chopped and unidirectional fibers to improve crash energy absorption, manufacturability, and weight.
- Recessed Reinforcing Pipe Profile for Two-Sided Body Shell Joining
Recesses in a body reinforcing pipe open tool access for two-sided spot-welding, riveting, or clinching, cutting shell assembly cost and complexity.
- Vehicle Monitor Base Assembly With Stopper-Guided Cover Edge Fixing
Integrated stopper parts lock the cover edge to the base, preventing lift, drop, and deformation in vehicle periphery monitoring assemblies.
- Vehicular Back Door Joint Structure With Rotation Stop Bracket
A rotation stop bracket stabilizes a resin back door joint during adhesive curing, preventing grooves, delamination, and water ingress.
- Utility Vehicle Door Strut Control for Stable Open Position
A pneumatic strut between the door and B-pillar resists wind and gravity, keeping a utility vehicle door open and accessible.
- Automotive Exterior Panel Frame With Nested Struts for Impact Absorption
Intersecting struts with a groove-based nested joint absorb impact loads, keep panel stiffness, and avoid weight and forming complexity.
