The market has shown that there is a need to plan, monitor and continuously evaluate and optimize personal training. Until today, this typically required several devices from multiple vendors. GN Netcom lacked resources to help develop a 3D master model to a brand new “all-in-one” training unit with integrated heart rate monitor. To achieve a heart rate monitor that can measure so precisely that there is only 0.8 % deviation from the scientific Electrocardiogram (ECG), it is very important to have a good ear fitting.

In cooperation with GN Netcom and the external designer, Technolution was responsible for the construction of the final 3D model.  In 3 weeks, Technolution created a robust and effective “master model” ready to use for retail construction of the headset itself.

Ears are different and have geometrically complex shapes. This means that the prototype development required great flexibility in the underlying 3D models. Technolution develop a 3D “master model” that could be change easily based on usability tests and automatically adjust the necessary changes in all sub-components.

The 3D “master model” made it possible to develop and deliver the product with only 4 different “EarGels”, and still assure a good and comfortable fitting.
