I-Bumper inemisebenzi yokukhusela okukhuselekileyo, ihombisa imoto kwaye iphucule iimpawu ze-aerodynamic zesithuthi. Ngokwendlela yokhuseleko, imoto ingadlala indima ye-buffer kwimeko yengozi yesantya yesantya esiphantsi kwaye ikhusele umzimba wangaphambili nangasemva; Ingakhusela abahambi ngeenyawo kwimeko yeengozi nabantu abahamba ngeenyawo. Ngokwembonakalo, kuyayihlonipha kwaye iye yaba yinxalenye ebalulekileyo yokuhombisa ukubonakala kweemoto; Kwangelo xesha, i-bumper yemoto ikwanayo nefuthe elithile le-aerodynamic.
Kwangelo xesha, ukwenzela ukunciphisa ukwenzakala kwabakhweli kwimeko yengozi yefuthe lempembelelo, i-Bumper emnyango ihlala ifakwe emotweni yokuphucula amandla okuchasene nomnyango. Le ndlela iyasebenza kwaye ilula, inotshintsho oluncinci kwisakhiwo somzimba, kwaye isetyenziswe ngokubanzi. Kwangoko i-shenzhen ye-ofisi yemoto ye-1993 ye-Shenzhen yavula inxenye yomnyango ukuze iveze i-Bumper kubaphulaphuli kubaphulaphuli.
Ukufakwa komnyango we-bumper kukubeka i-beams yentsimbi ephezulu kakhulu okanye ngokungagungqiyo kwiphaneli yomnyango ngamnye, ukuba i-cumper ye-tumper, ukuze i-Wall yodonga iphela inesithuba sendawo yokhuseleko. Ewe kunjalo, ukufaka olu hlobo lohlobo lwe-bumper kuya kunyusa ezinye iindleko kubavelisi bezemoto, kodwa kubakhweli bemoto, ukhuseleko kunye nokhuseleko kunye nengqondo yokhuseleko kuya kwandisa kakhulu.
