Doors TRIZ Cases
- Adjustable Support Beam for Tarpaulin Loading Space
An adjustable support beam resolves wheel jamming by varying carriage distance for quick opening.
- Asymmetric Hinged Front Doors for Central Engine Sports Cars
Asymmetric hinge placement positions the door sill under the wheel, resolving central engine clearance conflicts while ensuring full leg stretch.
- Sliding Tarpaulin Tensioning Shaft with Integrated Customs Seal
A tensioning shaft integrates a rotatable customs clamp part secured by an internal rope to hold the side tarpaulin in place.
- Height Adjustable Tarpaulin Structure for Commercial Vehicles
A tarpaulin holder fixes the side panel above the stanchion body to maintain a sealed roof connection during height adjustment.
- Motor Vehicle Door Opening Structure Reinforcement
Outer reinforcement couples to the inner panel between end walls to enhance edge rigidity.
- Vehicle Tailgate Guide Means for Translational Movement
Guide means on the tailgate and vehicle body constrain movement along a predetermined path, resolving forced distance obstacles during loading.
- Vehicle Sheet Beveling Using Third-Degree Curves
Segmenting the fold into arcuate sections and a flattening zone resolves the contradiction between visual appearance and collision-free movement.
- Vehicle Door Storage System with Pivotable Support
A movable cargo area storage system transitions to an expanded position for vertical door placement using a pivotable support panel.
- Door Coupling Mechanism for Direct Longitudinal Force Transfer
Releasable door coupling members transfer longitudinal collision forces directly between doors, bypassing the B-pillar to reduce force transfer delay.
- Vehicle Door Water Shield with Foam Cover for Noise Dampening
A vehicle door water shield uses an expanded foam cover attached to a waterproof sheet to seal access openings and dampen panel vibrations.
- Vehicle Slide Door Support Arm Rotation Restriction
A rotation restriction mechanism locks the support arm at specific positions during opening to prevent swing and maintain rigidity.
- Dual Actuator Side Door for Rear Passenger Access
A second actuator behind the front door allows rear passengers to open the panel and adjust seats without forward leaning.
- Vehicular Resin Back Door Corner Joint Design
Overlaid resin outer panels join at corner portions to enhance torsional rigidity and waterproofness without adding separate reinforcement structures.
- Isothermal Curtain V-Rib Sealing for Refrigerated Vehicles
V-shaped rib panels interlock to seal refrigerated compartments, preventing liquid infiltration and food loss.
- Vehicle Door Film Pocket Stamping Actuator Sealing
A pocket-like stamping adapts to actuator geometry to eliminate gaps and tearing risks in vehicle door films.
- Sliding Curtain Rear Closure for Freight Units
A sliding curtain suspended from an upper track provides quick rear access to freight units without lower tracks.
