True. There are many product innovation happened in the past with accident. I would like to add the point that innovative ideas happens with accident; but the innovative ideas are followed by various tools and methodologies of Lean Six Sigma to convert that into innovative product (Feasibility and Scalability). It has to undergo intense checks in these processes. So the Lean Six Sigma is equally much of importance and value for the product innovation. The following example is the best way to understand it.
In the year 2004, two scientist and reknowned professors of Manchester University,UK named Andre Geim and Konstantin Novoselov discovered the the material called Graphene accidently while researching on Graphite in their chemical laboratory.
Graphite is 3D structured carbon material, the commonly used as main ingredient in making of pencil which whole mankind known. The Graphene is a single layer of Graphite which was invented through mechanical clevage of cellotape.
Graphene has tremendous unique properties
It is a one atom thick carbon material.
It is 2D material (means it has length and width but has no mass).
It is Electronically, Electrically and Thermally conductive Material(The only material in the world).
It is thinnest material known to mankind (1000 times thinner than single sheet papaer and human hair).
It is flexible.
The important to mention that it is thiker than Diamond(200 times) and stronger than furness steel (300 times).
To make use of these unique propertiesof Graphene in various product /industry application, there was need for innovative product design, where the DMADV, QFD are used and brings the value of Lean Six Sigma in picture.
One of the best application of Graphene is Flexible Electronics. No wonder, in the age of technology revolution(4th revolution) every phone user want their mobile phones ro be more smarter than ever. Some of the common expectations of 21st century's consumer are going tobe fulfilled by use of Graphene(also called wonder material) in near future.
This material is used by many companies like Samsung, Sony, Lenovo, Nokia and every electronics manufacturing giant for designing the flexible display of mobile phones. This is also being use in making of Graphene mobile batteries which will charge your phone in 30 sec to 1 min. in future.
With the help of Graphene being used by companies like Intel, creating processors which will run thousand times faster.
(the list of application is long and long.)
To innovate all these products like Flexible Mobile Displays, Thinner Batteries, Faster Processors, Supercapacitors and so on, it has to undergo various Lean Six Sigma tools and methodologies which going to create value for their consumer(end user) in future.
So, to conclude, processes invovled in innovative ideas to creating a finished product which creates value for Lean Six Sigma in Designing the Product, Designing the Quality Parameters, Designing the Manufacturing Processes and so on.
These processes will be followed with the valueable feedback of the customers and improving product with Kaizen, Poka-Yoke, DFSS, Mistake Proofing with better versions.
The other industry applications of Graphene are
Paint and Anti Corresive Paints
Print and Packaging
Construction Industry
Palstic and Plastic Composites
Automative industry
Aerospace and Spaceship Building
...
Not but the least, Graphene is accidently innovated "Wonder Material" which is then creatively used with the help of Lean Six Sigma
