Dewert Okin Linear Actuators
Lippert Studios has been working with Dewert Okin for over 15 years on projects ranging from hospital bed drives and customised user interfaces to specialised linear drive systems. Dewert Okin was formed from the merger of the two German innovators Dewert and OKIN, who made their name in the 1980s with early developments such as the Dymat and OKIMAT drives. Today, Dewert Okin is part of the Phoenix Mecano Group and remains a leading supplier of drive and system technology for medical applications, beds, seating and office solutions.
Delta Drive
Elegant and minimalistic linear actuation motor system
Final Prototype
The DeltaDrive features a dynamic, compact design. Thanks to the small number of parts, installation is significantly simpler than with the previous drive model. Interchangeable end caps allow the ER or QR functions to be changed, which can significantly reduce production costs.

MCL II
the heart of every drive system
Final Prototype
The MCL II is a standalone component, but can also be connected to a single drive to form a single unit.
Fastening options
Fastening clip
Recesses on the top and side surfaces of the foam core allow it to rotate in line with the position of the aluminium profile. By simply adjusting the foam core, the control unit can be fitted to various drives with different profiles.
Fastening strap
A flexible strap allows the drive housing and its aluminium profile to be secured to the control housing using Velcro.
Apex Drive
A powerhouse for the smooth and safe lifting of patients.
Communicating Power
Visual USP communication
he unique selling point of this particular motor was its ability to generate a force of up to 12 kN. To convey the linear drive’s performance capabilities, we began with visual research focusing on industrial forms that naturally convey strength and power. We gathered references from the fields of aviation turbines, V8 engines, cylinder blocks, reinforced housings, heat sinks and high-tolerance mechanical assemblies. The aim was to identify visual cues that signal strength. This research guided the aesthetic direction and established a design language.
Setting a visual direction
Using these references, we translate the visual cues we have gathered into initial concept sketches. In this phase, we explore silhouettes, proportions and recognisable visual features that subconsciously link the actor to the predefined aspects.
3D Modelling for manufacture
We switch to CAD and refine the concept into a shape that accommodates the internal components and technical constraints. Mounting points, wall thicknesses, tolerances and the internal geometry of the motor redefine the shape. In this way, the design is transformed into a manufacturable housing, whilst retaining the visual identity of the sketches.
The CAD models are prepared for the client and used to create clean, high-resolution 3D renderings. These present the final design with realistic materials, lighting and proportions. In the case of the 12 kN Alpha drive, the design was further refined to adapt it to its specific application in a patient lift.
