Iyo bumper ine mabasa ekudzivirira kuchengetedza, kushongedza mota uye kugadzirisa maitiro eaerodynamic yemotokari. Panyaya yekuchengetedza, mota inogona kutamba buffer chikamu chebufer kana yakadzika-yekumhanyisa tsaona uye kuchengetedza kumberi uye kumashure muviri. Inogona kuchengetedza vanofamba netsoka kana tsaona nevanofamba netsoka. Panyaya yekutaridzika, inoshongedza uye yave chikamu chakakosha kurongedza kutaridzika kwemotokari; Panguva imwecheteyo, iyo mota bundu zvakare ine imwe yeiyo aerodynamic.
Panguva imwecheteyo, kuitira kuti uderedze kukuvara kune vafambi muchiitiko chekuchinja tsaona yekukanganisa, gonhi bumper rinowanzo kuiswa pamota kuti isimbise iyo anti-collision kukanganisa simba remusuwo. Iyi nzira inoshanda uye yakapusa, nekushandurwa kushoma kune chimiro chemuviri, uye chakashandiswa zvakanyanya. Pakutanga kwa1993 Shenezhen International mota Exhibition, Honda Accorct yakavhurwa chikamu chesuo kuti ifumure musuwo kune vateereri kuratidza kwayo kwekuchengetedza.
Kuiswa kwesuo kweimba kunofanirwa kuisa mwero wakakwira-simba Ehezve, kuisa rudzi urwu rwemusuwo bumper hakuzowedzera kuwedzera mamwe emitengo yemotokari dzevatambi, asi vafambi vemotokari, kuchengetedzeka uye pfungwa yekuchengetedza ichawedzera zvakawanda.
