Product innovation is often a process for improving existing products.Low-end disruptive innovation(LDI)enables a product to meet the most price-sensitive customers in the low-end market.The existing LDI methods are mainly based on unnecessary characteristics of disruptive innovations.Thus,they cannot easily identify and respond to the LDI design needs.This study proposes a hybrid method for the product LDI in two levels of the product design based on the summarized definition and essential characteristics of LDI.Feasible areas of the product LDI are determined using a hybrid relational function model to identify the maturity of dominant technologies.The technologies are identified through the technical search and evaluation of the feasible area for innovation to form an initial LDI scheme.Then,the product function is optimized using the trimming concept of theory of inventive problem solving based on the characteristics of LDI.The final LDI scheme is formed and evaluated based on the essential characteristics of the product LDI.The feasibility of the proposed method is verified in the design of a new dropping pill machine.

This paper presents the conceptual design stage in the product development process of a natural fiber composites of the side-door impact beam,which starts from idea generation to the selection of the best design concept.This paper also demonstrates the use of the integrated theory of inventive problem solving(Function-Oriented Search)(TRIZ(FOS))and Biomimetics method,as well as the VIseKriterijumska Optimizacija I Kompromisno Resenje(VIKOR)method.The aim of this study was to generate design concepts that were inspired by nature and to select the best design concept for the composite side-door impact beam.Subsequently,eight design concepts were generated using the TRIZ(FOS)-Biomimetics method and finite element analysis were used to analyse their performance and weight criteria using ANSYS software.VIKOR method was used as the multiple criteria decision making tools to compare their performances,weight and cost criteria.As a result,design concepts B-03 and C-02 were ranked as the first and second best,with VIKOR value of 0.0156 and 0.1178,respectively,which satisfied the conditions in VIKOR method.This paper shows that the integrated method of TRIZ(FOS)-Biomimetics and VIKOR can assist researchers and engineers in developing designs that are inspired by nature,as well as in selecting the best design concept using a systematic strategy and justified solutions during the conceptual design stage.
