Njengesitsha esiphathekayo esivamile empilweni yesimanje, izinkomishi zephepha zidizayinwe ngokuhlanganisa izimiso ezivela emikhakheni eminingi, okuhlanganisa isayensi yezinto, i-fluid dynamics, ne-ergonomics, okuhloswe ngayo ukuzuza ibhalansi phakathi kokusebenza, ukusebenziseka kalula, kanye{0}}nokusebenza ngempumelelo kwezindleko zokugcina uketshezi.
Ngokombono wesakhiwo, izinkomishi zephepha ngokuvamile zifaka umzimba oyi-conical noma oyi-cylindrical. Lo mumo uhlakaza ngempumelelo umfutho we-liquid futhi uvimbele ukuthinta. Idizayini ye-conical ikhululekile kakhulu ukubamba futhi isebenzisa impahla encane kunomumo we-cylindrical womthamo ofanayo. Isisekelo senkomishi ngokuvamile siyisicaba noma sigobe kancane, sinezimbambo eziqinisiwe noma inqubo egoqayo-kabili ukuze kuthuthukiswe{4}}umthamo wokuthwala nokuvikela ukuwohloka lapho uphethe iziphuzo ezishisayo.
Mayelana nokukhethwa kwezinto ezibonakalayo, ungqimba lwangaphakathi lwezinkomishi zephepha lumbozwe nge-polyethylene (PE) noma i-parafini wax ukuze kwakhiwe umgoqo ongenamanzi ukuvimbela ukungena kwe-liquid. Eminyakeni yamuva nje, ukukhathazeka ngokuvikelwa kwemvelo kuye kwagqugquzela ukuthuthukiswa kwama-coatings abolayo kanye nemiklamo engasebenza kabusha{1}}yezinto ezibonakalayo, efana nokusetshenziswa{2}kwezinto ezisekelwe esitshalweni ezifana ne-PLA (i-polylactic acid) ukuze kuthathelwe indawo ipulasitiki evamile. Isendlalelo sangaphandle senziwe ngephepha-lebanga elihlangabezana nokumelana nokucindezela, ukumelana nezinga lokushisa, kanye-namazinga angewona ubuthi.
Ngokuya ngesakhiwo esisebenzayo, izinkomishi zephepha zitholakala ngamanani anezigaba (isb, 80ml kuya ku-500ml) elungiselelwe izimo zokusetshenziswa ezihlukene. Isibonelo, izinkomishi zekhofi ngokuvamile zifaka -izibambo ezivimbela ukushisa noma imikhono ukuze kwandiswe indawo yokuxhumana nokunciphisa ukudluliswa kokushisa. Eminye imiklamo ihlanganisa unqenqema olugoqiwe ukuze kuthuthukiswe ukunethezeka kokuphuza nokuqinisa imiphetho ukuvimbela ukudabuka.
Ngaphezu kwalokho, izinkomishi zephepha ziyabekeka ngenxa yokuhlehla noma ama-grooves emzimbeni wenkomishi, okwenza kube lula ukuzithwala nokugcina. Imvelo yawo engasindi (enesisindo esicishe sibe ngu-3-i-10 amagremu inkomishi ngayinye) inciphisa ngokuphawulekayo izindleko zezokuthutha, kuyilapho izinqubo ze-prototyping ezisheshayo (ezifana nokusika i-die-cutting and lamination) zithuthukisa ukusebenza kahle kokukhiqiza.
Kafushane, ukwakheka kwenkomishi yephepha kubonisa ukuhlanganiswa kokusebenziseka nokuthengeka. Izitayela zesikhathi esizayo zizobeka phambili ukusetshenziswa kwezinto ezisimeme kanye nolwazi oluthuthukisiwe lwabasebenzisi.
