The causes of accidents and the resulting injury can be due to many factors – work accidents, sports, sudden movements in everyday life, crashes, overloads and falls. It all started with my client and already a partner in this project – Ventsislav Angelov. After a injury and a recovery process, he came to the conclusion of a feeling of discomfort, inconvenience and inadequate functionality in the standard and familiar to us all crutches. After thorough analysis of the relevant products in this area, a product has been developed that has a specific multifunctionality. This partnership project led to the creation of product identity – UNIERGO.
