Goynta jeexitaanka Dib-u-isku-darka Habka derbiga qoto dheer (TRD ee gaaban) wuu ka duwan yahay habka derbiga isku dhafan ee ciidda (SMW). Habka TRD, qalabka miinshaarta silsiladda ayaa lagu dhejiyaa qayb leydi dheer leh "goob gooyn" oo la geliyo dhulka, si loogu dhaqaaqo jarista iyo daadinta qashinka, isku dhafka, kicinta, iyo xoojinta ciidda goobta asalka ah, si samee gidaarka diaphragm ee dhulka hoostiisa. Habkan ayaa markii ugu horreysay laga sameeyay Japan 1994-kii si loo sameeyo darbiyo la gooyay ama gidaarada diaphragm-ka ah, taas oo si weyn loogu isticmaali jiray saldhigyada tareenada, meelaha qashinka lagu daadiyo, darbiyada aan nadiifka ahayn si looga hortago wasakheynta biyaha dhulka, iwm. Habka TRD ayaa si weyn loo isticmaalay goobaha shaqada ee Japan ilaa 1990-meeyadii. Habka TRD helo horumar degdeg ah, tan iyo markii TRD markii ugu horeysay lagu soo bandhigay Shiinaha ee 2009. Kaliya sanadka 2018, guud ahaan meelaha derbiga sameeyey habka TRD waa ilaa 1 milyan oo mitir oo laba jibbaaran iyo in ka badan 80 mashaariicda gudaha.
