Ikireka cy'Umusatsi Polygon ni ikireka cy'umusatsi cyakozwe kugira ngo gikoreshwe buri munsi mu gushushanya umusatsi. Imiterere n'aho udufindo two gufata umusatsi duherereye bitandukanye n'ibiri ku bireka bisanzwe by'umusatsi, bityo bikaba byemerera gufata umusatsi munini. Imiterere n'aho utu dufindo duherereye birinzwe n'impushya (patents) muri Amerika na Japani. Iki gikoresho cyakozwe muri aluminiyumu, ibyo bikaba bituma kiba kiremereye buhoro ugereranyije n'ibireka bya kera byakozwe mu bindi byuma. Umubiri woroheje ugumana umusatsi igihe kirekire, kandi ugabanya akababaro katewe n'ibireka biremereye. Imiterere yacyo yakozwe hakoreshejwe ikoranabuhanga rya mudasobwa (computer-aided design), hanyuma gikorwa hifashishijwe ibipimo bya rubber n'uburyo bwo gushonga no gucuruza ibyuma (casting).

Igishushanyo cyiza nuwatsindiye igihembo cyumuringa mububatsi, kubaka no guhatanira imiterere. Ugomba rwose kubona ibihembo bya bronze byegukana ibishushanyo mbonera bya portfolio kugirango umenye ibindi byinshi bishya, bishya, byumwimerere kandi bihanga imyubakire, inyubako nuburyo bwo gukora.
