Fans on sports events bring with them an ensemble of paraphernalia, which are more or less out of date and awkward. Most of them do not produce noise, and are bulky to transport. Because of these shortcomings, the idea of their improvement appeared. After the market research was done, development guidelines with main and side goals were set, and solution conceptualisations began. Models that were made with development methods were printed as prototypes and tested, which gave a foundation for their optimisation. Product compliance was rated according to economic, technological and user interface factors.
