Human machine cooperation

Daimler AG TecFabrik Leanfit

The mounting system LeanFit from the Daimler AG gives an outlook on the future collaboration between man and machine in modern assembly workstations. Defortec developed the design concept and the functional structure of the entire system consisting of the Leanfit gripper system, control unit and control box. Defortec manufactured and supplied this system in record time, which was presented to the audience at the annual meeting in 2016 in Berlin.

The main focus of the development was on an optimized user ergonomy and compliance with the strict MRK guidelines. The volume-reduced design provides an optimal, unobstructed view of the door position as well as on the screwing points of the door hinges. The lightweight aluminum construction allows with lowest weight, maximum strength and high transparency of the component.

The sensitive robot technology perceives the human being, deviates him actively and thus avoids any threat to the worker. The LeanFit system is used in production for the assembly of car doors. The robot performs large-scale movements automatically and precise positioning processes are carried out by the human using a joystick.

Ergonomic optimization
Kinematics detail

Operating unit

The ergonomically designed operator terminal provides all functions for controlling this complex system. A combination of 3D joystick, enable switch and emergency stop gives total control in any work situation.








Kinematics
The interface between the robot and the gripper system is formed by the kinematics, which is based on the swash plate principle. The latest tension and pressure sensors make the precise fitting of components possible.

Gripper adjustment

Function and design

The design of the gripper system with its soft-edge shape protects the user from injuries. The flat suction pads are easily adjustable in their distances to safely accommodate different sizes of doors.

Awarded design

The visionary tool of the Daimler AG is awarded with the prestigious iF Design Award 2017 and the Designpreis Baden-Würrtemberg Focus Open 2016.

"Design Center"

Design Center Stuttgart is the only State-owned design center in all of Germany. Located in „Haus der Wirtschaft“ in the middle of Stuttgart, it‘s the most important part of economic development support in Baden-Württemberg. It provides information and advice about professional design. As part of the promotion of trade and industry, it especially offers small and medium-sized enterprises guidance on current design topics. The Design Center Stuttgart offers companies and creative service providers the ideal platform for making contacts and networking. The cooperation with federations, the Chamber of Industry and Commerce, Center of Innovations and comparable institutions often plays an important role.
