From user research to the final product.
Key requirements for the rollator of the future
Rollators enable people with limited mobility to remain active and independent in everyday life. However, many existing models are heavy, ergonomically flawed, and visually unappealing.
On behalf of a medical device manufacturer, we explored what the rollator of the future should look like and developed two models — from an initial design vision through product design and engineering.
At the beginning of every design thinking process lies a deep understanding of the people who will use the product and their needs. As part of our user research, we accompanied rollator users in their daily routines to observe real-life challenges and conducted in-depth interviews to uncover their motivations and barriers.

This phase also included observations and interviews in medical supply stores to better understand the criteria used when purchasing rollators — often bought by younger family members.
GENERATING IDEAS
Based on our research insights, an innovation workshop with the client team sparked a wide variety of new concepts. Through a cross-industry innovation approach, we drew inspiration from adjacent product categories like bicycles and strollers.
Based on the workshop results and an analysis of current design trends, we developed an initial concept and several design visions for the future product range. Key assumptions were tested as early as possible through rapid prototyping of individual components.
Creating a design vision
technological innovation
One of the key challenges with existing rollators lies in poor vibration damping and limited ergonomic comfort. Especially with lightweight models, the high frame stiffness transfers every uneven surface directly to the user’s hands and wrists. In addition, uncomfortable grips and suboptimal grip angles often make longer walks exhausting and unpleasant.
By transferring expertise from carbon bicycle frame engineering, we developed a vibration-damping frame for the new lightweight rollator. Combined with newly designed grip geometries and materials, overall ergonomics were significantly improved.
Additional innovations such as integrated lighting, a smartphone interface for connected mobility scenarios, and a contemporary, emotional design further differentiate the new rollator.
Designing lightweight structures sustainably
Keeping weight to a minimum is a core requirement for any rollator. While carbon fiber reinforced plastics are commonly used for lightweight designs, they are difficult to recycle and dispose of sustainably.
A second rollator model therefore focused on bamboo as a renewable raw material, combined with metal joints that can be easily separated and reused — placing sustainability at the center of the design.
Once again, we drew on proven expertise from the bicycle industry, where bamboo frames have been successfully used for many years.
Testing in real-life conditions
Following the product design and engineering phases, prototypes of both rollator models were built. This step made it possible to test the developed designs and technical solutions in real-world conditions and prepare for production.
By combining deep user understanding with strategic product design and innovative engineering, we created forward-looking products that are not only highly functional but also visually appealing.

For the rollator project, our team led the full innovation and product development journey — from user research and design through to detailed engineering and final technical drawings.
Michael led the design thinking process and concept development, while Matthias and Adrienne were responsible for product design and Paul for technical engineering.
