Abstract

“Innovation activities” means all the scientific, technological, organizational, financial and commercial steps aimed at implementing innovation. Some innovation activities are themselves innovative, others are not new, but they are necessary for the implementation of innovation, such as Research and Development not linked to a specific innovation. Innovation has a close reference to the economic market, that is to say with the users of the innovated product: if these are not sufficiently developed they are not able to understand it and appreciate it. Innovation, making the process better, generates greater competitiveness: it is the dream of something better that translates into general well-being. This work presents an innovative hybrid car’s design, belonging to the E-segment. The choice of this segment is already innovative in its nature, as despite being currently in strong development, hybrid and electric engines are still little used for large sedans. The method we present in this paper for the car design is also innovative and is called Design for Six Sigma. It is a method used to develop new products, through the determination of customer and market needs and the transformation of these requests into the product generated.

Highlights

The method we present in this paper for the car design is innovative and is called Design for Six Sigma
The Design for Six Sigma consists of a design method for the development of new products that aims to better respect the demands and expectations of the customer
On the basis of research experience, it was stated that the most challenging phase is end-of-life stage. This issue could be supported by design strategies, as Design for Disassembly (DfD), that help designers to take care of the disassembly of products in order to recycle, reuse, remanufacture, correct disposal [9,10,11]

Summary

Introduction

The Design for Six Sigma consists of a design method for the development of new products that aims to better respect the demands and expectations of the customer. - CDDOV; Concept, Define, Design, Optimization and Verification phases. - IDDOV; Identify, Define, Develop, Optimize, Verify. The basic activities that are carried out in a Design for Six Sigma approach are the following: investigation of customer requests and needs, analysis and classification of such requests, transformation of customer requests into engineering information, design development, verification performance, and implementation of processes in line with the objective to be achieved. TRIZ is the Russian acronym for the “Theory of Inventive Problem Solving,” an international system of creativity developed in the U.S.S.R. between 1946 and 1985, by engineer and scientist Genrich S.
