High-Tech in Everyday Life: The Invisible Precision of Modern Door Systems

Did you know that a modern car door – depending on vehicle type, equipment, and safety requirements – can consist of up to 200 mechanical components?

What seems simple at first glance is actually a highly complex interaction of mechanics, kinematics, and integration: from the satisfying "click" when closing the door, to the millimeter-precise fit, to tuning for crash tests and comfort requirements.

The development of modern door and closure systems is a prime example of interdisciplinary engineering:

Kinematics – For precise movement sequences, defined detents, and perfect haptics

Crash and Safety Design – Including side impact protection, child safety locks, and airbag integration

Mechanics & Actuation – For locking systems, window regulators, electric drives, and damping elements

Manufacturing and Assembly Relevance – With a focus on tolerance chains, joining technologies, and process reliability

System Integration & Durability – Ensuring trouble-free operation over many years and millions of cycles

And all this under one guiding principle: every movement must feel high-quality, every click must be precise.

Developing modern door and closure systems means one thing above all: precision, system-level understanding, and attention to detail.
