Mechanical failure or misalignment during the locking cycle prevents secure closure. Ensuring consistent latching improves passenger safety and vehicle security.

Inconsistent kinematic paths during opening and closing cycles lead to mechanical interference or seal failure. Stabilizing the motion path ensures structural integrity and user safety.

Physical barriers or lack of leverage points prevent safe and ergonomic vehicle ingress. Addressing this improves passenger accessibility and safety during entry and exit maneuvers.

Improper positioning of door fasteners leads to poor seal integrity and structural gaps. Correcting these deviations ensures aerodynamic efficiency and prevents mechanical binding.

External door handles often create aerodynamic drag or aesthetic disruption when not in use, yet must remain accessible for entry. Solving this ensures reliable handle deployment and retraction across varying vehicle operating states.
