Isixhobo sokuchonga iinwele sisixhobo esibalulekileyo kwishishini lempahla, esisetyenziselwa ukuchonga naziphi na iinwele ezikhululekileyo ezikhoyo kwintambo ngelixa isebenza ngesantya esiphezulu. Esi sixhobo saziwa ngokuba sisixhobo sokuchonga iinwele kwaye sisixhobo esibalulekileyo esixhasa umatshini wokugoba. Umsebenzi waso ophambili kukuyimisa intambo yomatshini ngokukhawuleza nje ukuba kufunyenwe naluphi na uhlobo lwentambo.

Isixhobo sokufumanisa iinwele sinamacandelo amabini abalulekileyo: ibhokisi yokulawula yombane kunye nebracket yeprobe. Iprobe ye-infrared ifakwe kwibracket, kwaye umaleko wesanti usebenza ngesantya esiphezulu kufutshane nomphezulu webracket. Iprobe yenzelwe ukubona uboya, kwaye xa isenza njalo, ithumela isignali kwibhokisi yokulawula yombane. Inkqubo yangaphakathi ye-microcomputer ihlalutya imilo yoboya, kwaye ukuba ihlangabezana nomgangatho ochazwe ngumsebenzisi, isignali yokukhupha ibangela ukuba umatshini wokugoba ume.

Isixhobo sokuchonga iinwele sidlala indima ebalulekileyo ekuqinisekiseni umgangatho wentambo eveliswayo. Ngaphandle kwaso, iinwele ezikhululekileyo kwintambo zinokubangela iingxaki ezahlukeneyo ezifana nokuqhekeka kwentambo, iziphene zelaphu, kwaye ekugqibeleni, ukungoneliseki kwabathengi. Ke ngoko, kubalulekile ukuba nesixhobo sokuchonga iinwele esithembekileyo ukuze kuncitshiswe ukwenzeka kwezi ngxaki nokugcina umgangatho wemveliso yokugqibela.

Ukuqukumbela, isixhobo sokubona iinwele sisixhobo esibalulekileyo kwishishini lempahla, sinceda ukuqinisekisa ukuba intambo eveliswayo ikumgangatho ophezulu. Ngokukwazi ukubona nokumisa umatshini wokugoba ngokukhawuleza, esi sixhobo sinokunciphisa kakhulu ukwenzeka kweziphene zelaphu kunye nezikhalazo zabathengi.
