This study aimed to design an innovative product which was a Multifunctional Locker which would be adapted to the needs of children in school for learning and utilizied as Education Supporting Tools (EST). The design of this Multifunctional Locker product used Conceptual Design method which includes stages such as identifying customer needs to the product, benchmarking the three competitor’s products so the specification of the product innovation would be identified, abstracting the design specification to get essential problems, forming product function structure with Functional Modeling and resulted 6 function structures, then elaborating those structures to be developed into the product's work structure and finally the final stage of design was to evaluate the concept of Multifunctional Locker which had been formed. The results obtained from this research were the product innovation of Multifunctional Locker had a concept that had met the criteria of the planned design specifications so that Multifunctional Locker can be easily operated, safe and comfortable used by kindergarten children for their learning and utilized as Education Supporting Tools (EST).
