Chikwama chosindikizira cha mbali zisanu ndi zitatu ndi mtundu wa chikwama chophatikizika, chomwe chimatchulidwa molingana ndi mawonekedwe ake. Chikwama chamtundu uwu ndi mtundu watsopano wa thumba lomwe latuluka m'zaka zaposachedwa, ndipo lingathenso kutchedwa "thumba lathyathyathya, thumba la pansi, thumba la zipper" ndi zina zotero.
Chifukwa cha malingaliro ake abwino a mbali zitatu, chikwama chosindikizidwa cha mbali zisanu ndi zitatu chimawoneka chapamwamba kwambiri ndipo chimakondedwa kwambiri ndi ogula.
Ubwino eyiti mbali kusindikiza matumba
1. Chikwama chosindikizira cha mbali zisanu ndi zitatu chili ndi masanjidwe asanu ndi atatu osindikizira, omwe angapangitse kuti chidziwitso cha mankhwala chiwonetsedwe chokwanira komanso chokwanira. Kukhala ndi malo ochulukirapo ofotokozera malonda ndikosavuta kulimbikitsa ndi kugulitsa malonda.
2. Popeza pansi pa thumba ndi lathyathyathya ndi kutsegulidwa, pansi pa thumba akhoza kuonedwa ngati mawonekedwe abwino kwambiri owonetsera ngati thumba layikidwa lathyathyathya.
3. Chisindikizo cha mbali zisanu ndi zitatu chimayima mowongoka, chomwe chimathandiza kwambiri kuwonetsera chizindikiro.
4. Chikwama cha zipper chokhala ndi mbali zisanu ndi zitatu chimakhala ndi zipper zogwiritsidwanso ntchito, ndipo ogula amatha kutsegula ndi kutseka zipper, zomwe bokosi silingathe kupikisana nalo.
5. Njira yosinthira yophatikizika yophatikizika imakhala ndi zinthu zambiri komanso kusintha kwakukulu. Nthawi zambiri amawunikidwa molingana ndi chinyezi, makulidwe azinthu, ndi zotsatira zachitsulo. Ubwino wake ndi waukulu kwambiri kuposa bokosi limodzi.
6. Kusindikiza kwamitundu yambiri kungagwiritsidwe ntchito, zogulitsazo ndi zokongola, ndipo zimakhala ndi zotsatira zolimbikitsa zotsatsira.
7. Maonekedwe apadera, osavuta kuti ogula azindikire, apewe kupeka, komanso kukhala ndi gawo lalikulu pakukweza mtundu.
8. Kuyima mokhazikika, ndikoyenera kuwonetseredwa kwa alumali ndipo kumakopa chidwi cha ogula.
Pansi pansi, imatha kuwonekera
Zosavuta kung'amba pakamwa kapangidwe, kosavuta komanso kothandiza.
Zogulitsa zonse zimayesedwa kovomerezeka ndi labu ya iyr yapamwamba kwambiri ya QA Ndikupeza satifiketi ya patent.
