1.Introduction

Recently,growingmarketcompetitionandincreasinglydiversecustomerdemandhasforcedcompetitorstoincreasethespeedatwhichtheydelivernewproductstothemarket.However,developingamoldformassproduc-tionrequiresconsideringnumerousfactors,includingproductgeometry,dimensions,andaccuracy,leadingtolongproductdevelopmenttime.Introducingmodulardesignconceptsintoproductdesignappearsakeymeanoffacilitatingproductdevelopment,sinceitincreasesdesignflexibilityandshortensdeliverytime[1–4].Mean-while,ahighlevelofproductmodularityenhancesproductinnovativeness,flexibility,andcustomerservices[5].
