Accident Situation Locks TRIZ Cases
- Vehicle Door Latch Support With Breakaway Cable Isolation
A breakaway support body isolates the ratchet and Bowden cable during side impact to prevent accidental door opening.
- Flush Handle Assembly With Inertia Release for Collision Deployment
An inertia-triggered release deploys a flush vehicle door handle during collisions when motor failure would otherwise prevent door opening.
- Vehicle Door Lock Support Structure for Side-Impact Opening Prevention
A breakaway support structure separates the ratchet and Bowden cable during side impact to prevent unintended vehicle door opening.
- Vehicle Door Lock Blocking Mechanism for Impact-Induced Deformation
A floating lock blocker follows outer-panel deformation during impact to keep the lever from releasing and prevent unintended door opening.
- Vehicle Door Reinforcing Bracket for Impact Latch Retention
A deformable reinforcing bracket shifts into the latch lever during impact to stop unintended release and keep the vehicle door closed.
- Vehicle Door Reinforcement Structure to Prevent Latch Release
A deformable door reinforcement contacts the latch during impact to keep the door closed and route crash forces into the B-pillar.
- Vehicle Door Load Path Structure for Engagement Retention
A load transmitting member redirects side impact force to the engaging member base, limiting door latch deformation and preventing disengagement.
- Vehicle Door Striker Mounting Structure for Side-Collision Load Distribution
Multiple locking rods spread side-collision loads across the reinforcement to keep the striker aligned and block door intrusion into the cabin.
- Vehicle Door Inner Panel Slot to Prevent Impact Opening
An attenuation slot near the interior latch handle limits handle movement during impact so the door stays closed and pillars absorb crash forces.
- Sliding Door B-Pillar Latch for Oblique Impact Retention
A catchment claw and T-shaped securing hook keep a sliding door latched to the B-pillar during oblique front impacts and pillar deformation.
- Motor Vehicle Lock Laser Reinforcement for Crash Load Resistance
Local laser hardening and laser-welded bearing components help a motor vehicle lock absorb crash loads without adding full-section weight.
- Vehicle Door Latch Restriction Mechanism for Collision Opening Prevention
A restriction mechanism locks the inertia lever in a non-operating position during impact, blocking ratchet release and accidental door opening.
- Reinforced Vehicle Door Lock Structure for Crash Load Retention
A reinforcing plate and multi-part lock holder raise tear resistance and load capacity so vehicle doors stay latched under crash loads.
- Vehicle Door Handle Spring Module for Side-Impact Latch Security
A secondary spring module linked by cables adds bias to the interior handle, preventing unintended door unlatching during side impacts.
- Two-Part Door Lock Striker for Higher Tear Resistance
A two-part sheet metal lock striker improves tear resistance and load absorption at the bracket-to-plate transition under extreme door loads.
- Motor Vehicle Door Lock Coupling Lever for Crash-Safe Opening
A pivoted coupling lever and torsion spring keep the door lock opening chain reliable under corrosion, contamination, and crash loads.
- Door Latch Stopper Bracket for Side-Impact Unlatching Prevention
A movable stopper bracket blocks the latch release lever during side impact, preventing unintended door unlatching while preserving normal opening.
- Vehicle Door Latch Roller Pawl for Low-Force Release
A roller pawl cuts ratchet friction to lower door release effort while a secondary pawl preserves striker capture during crashes.
- Deformable Bonnet Lock Case for Crash Force Reinforcement
A deformable lock case reinforces the bonnet locking mechanism during crashes, raising force absorption without extra reinforcing parts.
- Flush Door Handle Pre-Deployment for Collision Power Loss
Collision risk signals trigger a vehicle flush door handle before impact, preventing motorized deployment failure during power loss.
- Flush Door Handle Blocking Bridge for Crash Unlatching Prevention
An inertial rotor and bridge directly block the latch lever during a crash, preventing unintended door unlatching in flush vehicle handles.
- Rheopectic-Fluid Door-Handle Inertial Device for Crash Safety
Rheopectic fluid raises viscosity as rotor speed increases, limiting handle motion and helping prevent accidental door opening during crashes.
- Modular Door-Handle Inertial Device With Rheopectic Fluid
A rheopectic fluid and immersed rotor limit rotation during crashes, while modular mounting simplifies adaptation and replacement on vehicle door handles.
