Sauer Danfoss

JS7000 Joystick Series

Definition & Discovery

The JS7000 joystick series, a new line of joysticks for mobile equipment control, was born from an in-depth collaboration between Sauer-Danfoss and Brooks Stevens, Inc. Sauer-Danfoss relied on BSI throughout the development process of these new controls which feature a dual axis design, push button & trigger switches and right or left hand grips.

A multi-continental design research study identified surprising regional differences in use from an ergonomic and an interfacing perspective, leading to the identification of three distinct types of users the new designs would have to accommodate. They were defined by geography, equipment to be operated, level and format of switch technology employed, and even hand size.




Several iterations of drawings and clay models were guided by these video and interview insights, and tested through validation research. Validation models were cast in urethane with tactile switches installed for accurate evaluation of feel and accessibility. This phase of research showed improved behaviors with the new concepts compared to the current offerings.





Evaluation & Refinement

Our designers and engineers refined these concepts with vertical and horizontal design configurations in clay and cast urethane models for further ergonomic evaluation. Our engineers continued the relationship through assistance in mechanical design for manufacturing & assembly, production design & support.







The new joysticks give operators improved comfort, ease of control and manufacturers more flexibility in configuration. The strength of the product came from understanding the end-users and translating their needs into impactful design solutions.
