I-ERGONOMIC DESIGN: Ngendawo yephethini ye-wavy yensimbi enkulu nebukhali ebukhali, ifayela lensimbi engenasici nalo ligobile kahle ukuze lisetshenziswe kunoma iyiphi i-engeli, lishelela kalula izindawo okunzima ukufinyelela kuzo.
IZIMALI EZINGAPHEZULU: Yenziwe ngensimbi engagqwali echwepheshile, isethi yefayela yonyawo iyagezeka futhi iphinde isetshenziswe. Futhi athambile esikhumbeni sakho futhi asuse isikhumba esifile ezinyaweni zakho ngokuphepha nangokungenabuhlungu.
UKWENZIWA KWESISINDI: Isibambo se-rasp sefayela lezinyawo senziwe ngezinto ezisezingeni eliphezulu ezinokwakheka kwesithwathwa esingasheleli ukuze sinikeze ukubamba okuhle okwengeziwe. Izibambo zinembobo ukuze zilengiswe kalula futhi zomiswe ngemva kokusetshenziswa.
ISICELO: Ifayela lochwepheshe lensimbi engagqwali elifanele izintokazi, amadoda nabadala abanesikhumba esiqinile nesiqhekekile ezinyaweni
