Izici zokuphepha zibalulekile. Amafoni amaningi anamakhamera avelelayo afaka ukutholwa kokuwa kusetshenziswa i-accelerometer/gyroscope. Uma idivayisi itholakala iwela ngenkathi ikhamera ivuliwe, uhlelo luzozama ukuhoxisa ikhamera ukuze kuncishiswe ingozi yokuphuka. Ngaphezu kwalokho, isofthiwe kumele ibhekane nezimo ezifana nokucindezela umsebenzisi ikhamera noma into eyivimbayo.
7. Ukubhala kabusha kanye nokuphindaphinda komklamo
Ngaphambi kokukhiqizwa ngobuningi, kudalwa ama-prototypes ukuze kuhlolwe imiqondo kanye nokubekezelelana. Ama-prototypes angaba:
– Ukuphrinta kwe-3D kwezingxenye zokuqala (ukuhlolwa kwesimo nesikhala)
- Umshini wokugaya we-CNC wezingxenye ezidinga amandla nokunemba
- Amasampula okubumba ngomjovo ukuze ahambisane nezimo zokukhiqiza zangempela ezilinganisiwe
Ukuphindaphinda kuvame ukwenzeka izikhathi eziningi. Isibonelo, uma imodyuli inomsindo kakhulu lapho inyakaziswa, umklami uzoshintsha izinto zegiya, engeze i-lubricant, ashintshe isilinganiso segiya, noma afake ama-bushing. Uma imodyuli izwakala ikhululekile, ama-rails kanye nama-tolerances ayaqiniswa noma kufakwe izingidi zemishini.
8. Ukukhetha izinto kanye nenqubo yokukhiqiza
Izinto zokwakha kumele zibe lula kodwa ziqine. Ngokuvamile kusetshenziswa inhlanganisela:
– Amapulasitiki obunjiniyela (isib. i-POM, i-PC, i-PA) amagiya athile noma izindawo zokubeka izinto
– Insimbi (i-aluminium noma i-stainless) yezinsimbi zomzila nezingxenye ezithwala umthwalo
– Irabha noma igwebu lokuvimbela umsindo nokuvala
Ukuze kukhiqizwe ngobuningi, izingxenye zepulasitiki zenziwa ngokufaka umjovo, kuyilapho izingxenye zensimbi zenziwa ngokunyathela, ukushintshwa kwe-CNC, noma ukuphonswa nge-die, kuye ngesimo. Amagiya amancane adinga ikhwalithi ephezulu ukuvimbela ukuguguleka okusheshayo nomsindo owedlulele. Igrisi ekhethekile ivame ukungezwa, kodwa kumele iphephe kuma-elekthronikhi futhi ingasabalali kalula ku-lens noma ku-sensor.
9. Ukuhlanganiswa emgqeni wokukhiqiza
Imojuli ye-pop-up ivame ukuhlanganiswa njenge-sub-assembly ngaphambi kokufakwa emzimbeni we-smartphone eyinhloko. Izinyathelo ezijwayelekile yilezi:
