Weather/Dirt Prevention Locking TRIZ Cases
- Flush Door Handle Unlocking Cylinder for Fouling Protection
An inclined cylinder nested in a flush sliding handle keeps manual door unlocking accessible while protecting the key mechanism from weather and fouling.
- Vehicle Door Handle Assembly With Gasket Pads Against Panel Friction
An elastomer peripheral gasket seals the handle bowl while its pads shield the door-panel edge from friction, corrosion, and noise.
- Motor Vehicle Lock Dry Chamber Sealing
Flexible plastic film seals the dry chamber to equalize pressure differences from temperature fluctuations.
- Waterproof Door Latch Cover With Movable Sealing Body
An integrated cover with a movable main body reduces component count and assembly complexity while maintaining water prevention for door latch mechanisms.
- Motor Vehicle Lock Sealing Interface Design
A motor vehicle lock integrates a rail-and-slide sealing interface between the flexible plastic housing and transmission arrangement.
- Vehicle Handle Cap Sliding Guide and Snap-Fastening Mechanism
A vehicle handle cap uses guide cursors and grooves for curved external mounting along a snap-fastened path.
- Motor Vehicle Door Handle Removable Lock Cylinder Cap
Integrated C-shaped cap prevents water ingress and simplifies removal via cam-guided key motion.
- Motor Vehicle Door Handle Deflection Control
A support structure with a stop limits actuating lever deflection to prevent sticking caused by thermal expansion and moisture absorption.
- Vehicle Door Handle Dust-Proof Wall Design
A dust-proof wall surrounding the return spring coil prevents foreign matter from entering the mechanism, maintaining ease of operation.
- Flush Vehicle Handle Ice Removal via Mechanical Self-Service
A flush vehicle handle uses mechanical movement to break ice blockages without motorization.
- Motor Vehicle Lock Rotary Latch Dust Ingress Prevention
Elastomer contact surface component on rotary latch reduces friction and dust ingress, preventing increased opening forces over time.
- Vehicle Keyhole Cover with Flexible Annular Shoulder
A vehicle keyhole cover uses a flexible annular shoulder for secure friction fit.
- Motor Vehicle Door Lock Hollow Shaft Axial Positive Locking
A hollow shaft connects a rotary latch to a locking element via a plastically deformed bearing journal for secure axial engagement.
- Motor Vehicle Lock Seal Using Straight Plastic Strip
Straight plastic strip seals minimize material waste by eliminating large pad cutting for motor vehicle locks.
- Plastic Film Sealing for Motor Vehicle Component Housing
A plastic film seals a motor vehicle component housing opening to protect internal mechanisms from moisture and contamination.
- Vehicle Door Handle Assembly Noise Reduction via Gasket Compression
Compressing the peripheral gasket with strip hooks prevents friction noise between components without adding assembly complexity.
- Vehicle Door Handle Cover Engagement Mechanism
An extension part engages the handle body to prevent unintended cover detachment while allowing access to the cylinder lock.
- Motor Vehicle Latch Seal Clip Fastening
A motor vehicle latch seal uses a resilient clip to compress housing peripheral walls for secure assembly.
- Motor Vehicle Door Latch Third Lever Engagement
A third latch lever blocks rotation at an intermediate position, revealing unsteady engagement states caused by weatherstrip counterforce issues.
- Decorative Cap Water Guide Channel for Cylinder Lock
A decorative cap member integrates a water guide channel to direct infiltrated fluid toward an ejection opening.
- Inclined Wedge Edge Alignment for Vehicle Flap Coupling
Inclined wedge edges and grooves self-align vehicle flaps, preventing dirt ingress while maintaining secure frictional coupling.
- Vehicle Door Handle Water Evacuation Orifices
Drainage orifices pass through the handle and bracket to channel water away, preventing frost accumulation that blocks operation.
- Vehicle Strike Plate Sealing Lip Indexing Pin Design
A vehicle strike plate integrates a sealing lip around indexing pins to secure the movable panel.
