Viotar/Patent Research

Because no one of the group had any experience with patents a lot of research on this topic had to be done. On this page the results of this research is briefly summarized. Patent Research The design As already meantioned, the viotar has been designed to create new possibilities regarding to bowing instruments. The most important thing of this design, is that bowing speed and force are controlled continuously by the system. This has the great advantage that the player himself does not have to control these things, which make playing the instrument more easy and therefor playable for more people. At the same time, this design makes it possible to play chords which is impossible on regular bowing instruments. To meet the requirements, every individual string will be provided with a bowing belt driven by an electromotor. With this, the bowing speed can be controlled for every string individually. To control the bowing force, every bowing belt is also attached to a linear actuator. Existing patents Used ECLA-codes for the research In order to find out which patents already exist on this region, several ECLA-codes have been used for research. The following combinations of ECLA-codes and keywords have been used: G10 + String strike G10 + Bow wheel G10 + Violin string bow G10 + Mechanical bow G10D + Violin bow G10F + Violin G10F + Bow Selected patents From the results of our research, a number of patents has been selected which may have common things with the design of the viotar. This selection is also included in table 1. These patents are chosen because they have at least one aspect that seems to be the same as in our design for the viotar. The patent that has the most similarities with the viotar, is the one on the bottom of table 1 (US1425533 (A)). This patent describes self playing violin from the Mills brothers. Further developments of this design are described in the patents with numbers US1028495 and US0807871. The strings are bowed by little wheels. These wheels are attached to hinges, which push the wheels on the strings using a relais. The idea has strong similarities with the viotar. However, bowing speed and force are not controlled in this design, which is a clear and very important difference. Furthermore, this patent is about a fully automatic violin, where the viotar is played by a musician. Tabel 1: Selected patents from Viotar patenteerbaar? Uit het octrooionderzoek is gebleken dat het idee van de viotar niet geheel nieuw is. Er zijn elementen van de viotar die in bestaande octrooien zijn terug te vinden. Bijvoorbeeld het gebruik van strijkwieltjes in plaats van een strijkstok is niet nieuw. Ook het idee dat deze via elektrische aansturing op het bestrijken van een viool doormiddel van van bespeeld wordt met toetsen is in de octrooien terug te vinden. Wat echter niet terug gevonden is, is het idee om de strijkdruk en snelheid continu te regelen zodat er altijd zuivere tonen gespeeld worden. Op grond van deze resultaten zou het idee van regelen van strijkdruk en –snelheid mogelijk gepatenteerd kunnen worden. Het gebruik van strijkwieltjes in plaats van een strijkstok zal geen problemen opleveren, aangezien de gevonden octrooien reeds verlopen zijn.
