Electric handcart

Alongside Rehmus, we developed battery-powered, modular work machines for use in the agricultural industry.

Ideation Process​

The first steps in developing a multi-functional device consist of an intensive phase of idea definition, sketching and experimentation. The aim is to explore the ideal interactions and functions in combination with the form. Together with the customer, we define the central principles and objectives, to be sure we understand how the device should be used, perceived, and expanded in the future. These findings are incorporated into a series of design studies in which form, function, and modularity merge into a coherent whole and form the basis for later product development.

3D Design Process

Once the form communication has been established and the practical interaction points are clearly defined, the design process transitions into the 3D phase. At this stage, the concept begins to take tangible shape through detailed CAD modeling. We refine the overall form to evaluate proportions, ergonomics, and visual balance while also testing how the design behaves under real world conditions. This includes, among others, assessing manufacturability of all sub-assemblies, determining optimal material thicknesses, and defining standard parts. Moving into the 3D phase bridges the creative intent and semantic communication goals into engineering, and through the process defies conceptual ideas into production ready forms.

Control handle
As this is the primary point of interaction with the product, the movement of the Rehmus transporter should feel as natural as possible. Users should be able to intuitively understand which stick movement triggers which transporter movement.

Modular and flexible

The Rehmus system is designed to be modular, making it easy to expand with new attachments. This lets the user choose the right add-on for each task and keeps one main tool useful for years to come. Rehmus works closely with users to plan and develop future attachments, so the system can keep growing and adapting to new needs. This results in a wider range of uses and keeps the product open for further improvement.
