Iyo dhizaini ye trunk lid inobata zvakananga maitiro ekuenzanisa, kuvhara, nzvimbo yekuona uye kudzora ruzha rwemotokari. Kune zvakare zvinhu zvakawanda zvekufunga nezve dhizaini yedhizaini yesutukesi uye marongero ezvishandiso, kwete chete kuve nechokwadi chekubatana kwechivharo chesutukesi uye mota, asiwo kuve nechokwadi chehunyanzvi zvinodiwa zvechivharo chesutukesi pachayo.
Musangano wakashongedzwa wechifukidziro chesutukesi chinosanganisira mapenera emukati nekunze echifukidziro chesutukesi (inozivikanwawo sematehwe emukati nekunze), uye zvikamu zvakasimbiswa zvechifukidziro chesutukesi. Iyo shizha simbi yakashongedzerwa musangano mune yakazara pendi uye isina kuunganidzwa, uye ndiyo yakakosha furemu yekuona iyo yakazara modhi maitiro, simba, kuoma uye kuisirwa kwezvishandiso zvesutukesi.
Sechikamu chemotokari, chivharo chetrunk ndicho chakasiyana uye chinonyanya kunetseka chinhu chiri kumashure kwemuviri wemotokari. Kune rumwe rutivi, chivharo chetrunk chikamu chakakosha chechimiro chemuviri, maitiro ayo ekugadzirisa, simba, kuoma, kuvimbika uye teknolojia inofanira kusangana nezvinodiwa zvekushanda kwese kwemuviri; Kune rumwe rutivi, nzvimbo yekuona, kuchengetedzwa, kuvhara uye kumwe kushanda kwetrunk lid structure pachayo ine simba guru pakushanda kwechimiro chemuviri wose, uyewo chikamu chinokosha chekushanda kwezvinodiwa zvechivharo che trunk.
