Isingeniso Amantongomane elokhi enayiloni acwecwe, aziwa nangokuthi amantongomane wokukhiya inayiloni noma amantongomane enayiloki, awuhlobo lwezibophelelo eziklanyelwe ukunikeza okuphephile nokuthembekile.
Isingeniso Ukufakwa kwamaphaneli elanga kudinga ukusetshenziswa kwezixhumi ezihlukene ukuze kuqinisekiswe ukukhwezwa okuphephile nokusebenza kahle kwamaphaneli elanga. Izinto zokubopha zidlala indima ebalulekile
Imboni ye-fastener iyingxenye ebalulekile yemikhakha eminingi, ehlinzeka ngokuxhumeka okuphephile kwezinhlelo zokusebenza ezihlukahlukene. Eminyakeni yakamuva, imboni iye yabhekana nentuthuko ebalulekile eqhutshwa izimfuno zemakethe, ukuthuthukiswa kwezobuchwepheshe, kanye nezinhlelo zokusimama. Kulesi sihloko, sizohlola amanye amathrendi akamuva embonini ye-fastener, sigqamisa ukuthuthuka okubalulekile nokuqagela kwemakethe.
