Crowdsourcing intelligent design

Design intelligence,namely,artificial intelligence to solve creative problems and produce creative ideas,has improved rapidly with the new generation artificial intelligence.However,existing methods are more skillful in learning from data and have limitations in creating original ideas different from the training data.Crowdsourcing offers a promising method to produce creative designs by combining human inspiration and machines' computational ability.We propose a crowdsourcing intelligent design method called ‘flexible crowdsourcing design'.Design ideas produced through crowdsourcing design can be unreliable and inconsistent because they rely solely on selection among participants' submissions of ideas.In contrast,the flexible crowdsourcing design method employs a cultivation procedure that integrates the ideas from crowd participants and cultivates these ideas to improve design quality at the same time.We introduce a series of studies to show how flexible crowdsourcing design can produce original design ideas consistently.Specifically,we will describe the typical procedure of flexible crowdsourcing design,the refined crowdsourcing tasks,the factors that affect the idea development process,the method for calculating idea development potential,and two applications of the flexible crowdsourcing design method.Finally,it summarizes the design capabilities enabled by crowdsourcing intelligent design.This method enhances the performance of crowdsourcing design and supports the development of design intelligence.
