Doors TRIZ Cases
- Lightweight Tailgate Reinforcement for Oil Canning
Steel brackets and U-shaped reinforcements stiffen aluminum panels, preventing oil canning while maintaining lightweight design.
- Door Beam Height Increase via Inverted Press-Forming
Inverting the press direction buckles webs outward, allowing the door beam to fit limited spaces while increasing height for better energy absorption.
- Composite Reinforcement Insert with Overmolding Notches
A composite reinforcement insert uses flared notches for mechanical overmolding anchorage.
- Vehicle Sliding Slat Curtain Non-Parallel Guide Mechanism
A slat curtain system uses switching flaps to guide rollers along non-parallel main and secondary branches.
- Folding Support Curvature Resists Inward Collapse
A folding support central portion features a specific convex curvature that resists inward shifting when force is applied.
- Vehicle Door Frame Pillar Bridging Member Weld Bead Design
Multiple spaced weld beads bond the pillar and bridging member, distributing load to resolve single-point welding stiffness contradictions.
- Service Vehicle Door Connectors With Deformable Inserts
Deformable inserts compress interior panels against frame flanges to resolve structural integrity and sealing contradictions in service vehicle doors.
- Height-Adjustable Stanchion with Selective Pivot Joint
Selective pivot joints block movement during travel to maintain structural integrity while releasing for easy roof lifting.
- Vehicle Door Wall Component with Metallic Foam Grooves
Groove-shaped slots in an intermediate wall capture metallic foam, reducing metal usage and weight while maintaining structural strength.
- Automotive Door Element Composite Material Design
High-strength steel panels attach to formable joining parts via bolting or welding, resolving stamping defects while maintaining impact resistance.
- Aluminum Door Beam Webs Eliminating Welds
An aluminum alloy door beam eliminates web welds to prevent stress concentration and rupture during collisions.
- Vehicle Closure Panel Collapsible Member Fluid Drainage
Integrated drainage apertures in the collapsible member channel water away from the vehicle interior, preventing damage during open positions.
- Variable Inertia Door Frame Reinforcement
A hollow beam reinforcement with variable moment of inertia enhances vehicle door rigidity through segmented longitudinal members.
- Vehicle Door Frame Molding Garnish Integration
Direct garnish fixing to frame molding via thermal bosses.
- Vehicle Door Outer Skin Module with Integrated Stiffening
A vehicle door outer skin module integrates a fiber-reinforced shell with a stamped mounting frame to enhance structural rigidity.
- Commercial Vehicle Side Tarpaulin Reinforcement
Reinforcement elements in recessed areas distribute forces through the vertical tube, preventing tearing and extending service life.
- Liftgate Assembly A-Shape Reinforcement Stiffness
An inner panel with diagonal and vertical reinforcement ribs forms an A-shape structure that resolves stiffness weaknesses at the Z/Y center.
- Vehicular Door Panel Sliding Mounting Mechanism
Interlocking side stoppers on sliding panels eliminate separate screws, resolving assembly complexity while maintaining mounting strength.
- Vehicle Door Frame Reinforcement with Localized Thickness
Varying plate thickness across hinge, lock, and sash sections improves strength without increasing vehicle door weight.
- Tailgate Skin Retention Lip for Glue Distribution Control
A tailgate skin retention lip fits into a complementary housing cavity to bond the assembly.
- Vehicle Door Arrangement Preventing Overlap via Edge Pads
Edge pads on adjacent doors contact to prevent overlap, enabling independent operation while avoiding complex hinge redesigns.
