Case Studies From A Breakthrough Innovation
 
"Starting in August 2004, the Hong Kong government began sponsoring a deployment of TRIZ to a cluster of eight local companies. Over the course of the next 15 months, each company was invited to assemble a team of between 5 and 8 engineers and designers each of whom would be exposed to a series of six three-day TRIZ education and utilization sessions. The aims of the program were for each company to realize new products, patents and tangible financial benefits, and to measure the extent to which TRIZ allowed companies to accelerate their rate of innovation. This paper describes a collection of some of the success stories emerging from the program."

Law of Increasing Intelligence of Technical Systems

We discovered that human beings by collectively evolving their technical systems, are trying to make each technical system as close to a human being as possible - or at least a model of human being and its environment based on the current understanding of the world (for example, understanding of laws of physics and chemistry in making an automobile) and the current understanding of the system called the human being. As man understands the world around it as well as its body and its mind, it wants to create an "ideal man" or at least an idealized human of all technical systems it is creating. This is an unexpected discovery and may take the readers used to classical TRIZ, sometime to accept it.


Navneet Bhushan is a founder and director of CRAFITTI Consulting, an innovation consulting and research firm focused on co-crafting innovation in global enterprises. In his paper, Navneet makes some challenging conclusions about where and how ideal systems are evolving to.

A tool to estimate the strength and life of a Patent

TRIZ (Theory of Inventive Problem Solving) classifies inventions into five novelty levels. At level 1 are slight modifications of the existing systems.  At level 2 are those inventions that resolve a system conflict or contradiction using usually inventive solution or inventive principle used to solve similar problems in other systems.    At level 3, the inventions change one subsystem or resolve the system conflicts in a fundamental way. At level 4, the invention gives birth to new systems using interdisciplinary approaches. The level 5 inventions are closer to a recently discovered scientific phenomenon. See article for a complete discussion.

Case Study: Applying Triz in a non-technical setting for a fuel-cell start-up

 

By Jean-Francois Denault

1.    ABSTRACT

Denault head shotTRIZ is a systematic tool used to generate creativity and solve technical problems, but there is little litterature of its use in non-technical situations. This brings up the question: How can TRIZ be used to generate creativty and solve a non-technical problem?

The objective of this experiment was to use TRIZ in a non-technical setting. As such, the article is very exploratory in nature. Working with a private company, we identified and defined a non-technical problem, and experimented with TRIZ to generate creativity in an attempt to solve the problem.


KEYWORDS: Creativity, Brainstorming, TRIZ, Problem Solving


Other authors have explored TRIZ in a non-technical perspective, they have mostly done so from a theoretical perspective. For example, Mann (1999) and Terninko (2001) did excellent work in developing examples of applications of Triz principles in non-technical settings. With this article, I wish to add to existing literature by developing a case study solving a tangible problem.

THE REAL WORLD: TRIZ in Two Hours for Undergraduate and Masters Level Students!

Dr. Paul R. Filmore

School of Computing, Communications & Electronics

University of Plymouth, UK

 

The reality of overloaded university syllabi is very limited time for introducing challenging and comprehensive concepts like TRIZ. This paper shares e

xperience and knowledge, based on five years of ‘teaching’ TRIZ in the UK. Key areas covered are:-

  • Creating a need in the student to learn more e.g., demonstrate that TRIZ has more potential than student’s other present problem solving strategies
  • Using an interesting learning case study; researched by the author with Michelin (USA): the Tweel
  • Reporting the use of a computer assessment based on the lecture and self study. The assessment focuses students to access an electronic TRIZ book, electronic resources and the internet, to self study greater understanding of TRIZ (NB this is one way to get around limited timetabled lecture time). Results from student perceptions of their understanding of TRIZ and of experiencing a rich learning environment, are also examined.

Results from undergraduate and MSc student cohorts who have undertaken a TRIZ learning experience designed around the above, demonstrate a high appreciation of the potential of TRIZ and a measurable level of understanding.

Nontechnical Systems' Transformation Algorithm

by Eugene Chikov and Nikita Chikov

The article considers potential of caricature in the development of the creative thinking and reveals the structural model of the caricature creating process; it compares logical operations while solving inventive problems in techniques (Su-Field analysis) and while getting the new result within the context of the nontechnical system. This article also offers the formula of the nontechnical systems' transformation algorithm (solving of the nontechnical creative problem), which is common for all nontechnical systems.

 Key words: Su-field analysis, nontechnical systems' transformation algorithm, creative thinking development

 "The potential of trial-and-error approach is exhausted... That is why creation of the algorithms for solving technical, scientific and other tasks is not only possible, but also necessary. ARIZ will be followed by algorithms for solving the scientific and other tasks. The development of General Theory of Creative Problem Solving will inevitably be started some day. But now we are at the very beginning of our way."

Improving the Fuzzy Front End of Product Development for Continuous Innovation Incorporating TRIZ

Why have many legacy companies been unable to innovate continuously? A study of several famous companies that have stumbled in innovation reveals that it is not just one activity but a multitude of them that are not executed well. That is why "if it were easy everyone would be doing it." Innovation has been defined as invention brought to the market. The federal government has tried to measure innovation and found it very difficult. Work is ongoing to collect information on important factors for innovation but most measure factors that are results versus critical skills that drive innovation. A model for continuous innovation has been developed from a variety of sources, including the author's 40 years in the appliance industry. The model incorporates four key parts and arguably the most important part is problem solving and problem identification. This is where TRIZ plays a critical role since problems poorly solved or not solved lead to weak invention and innovation that can be trumped easily. The details of the model will be explained with associated forms that are useful for implementation.

An important aspect of TRIZ problem solving is noticing the resources needed to resolve contradictions. “Resources are things, information, energy, or properties of the materials that are already in or near the environment of the problem” (Rantanen & Domb, 2008). Because of the way we humans process information, however, we tend to overlook many possible resources. The normal processing of our perceptual and semantic systems leads us to notice the typical resources for the problem at hand. The typical is the enemy of innovation; whereas, the atypical, or the obscure, is innovation’s friend. But what techniques can help counteract our propensity for the typical and help us uncover the obscure? After devising an extensive taxonomy of possible types of resources, we have created and tested a set of techniques, the Aha! Toolkit, that helps uncover the obscure resources. Even though our set of techniques is only a year old, it has already been used to solve several difficult engineering problems. Further, it can assist TRIZ with problems that involve contradictions but will also work with problems involving no contradictions. We present our new cognitive theory of innovation as well as the techniques that help humans see the often-invisible obscure resources.

Holistic Value Framework using TRIZ and other frameworks
 
This article from Karthikeyen Iyer, Crafitti Consulting, shows opportunities can be gained by using some of the lesser know tools of TRIZ. In this context, there are several techniques associated with TRIZ that can be beneficial. Function-based thinking and Ideality can help in creating an improved understanding of value (and thereby waste). Nine Windows can broaden the context and scope of value stream mapping to provide an end-to-end perspective. For more information click below.

Improving the Fuzzy Front End of Product Development for Continuous Innovation Incorporating TRIZ

In this article, Dr. Coates explores why have famous companies failed to innovate on a continuous basis. Putting aside socioeconomic disasters, downstream product development failures, or rollout blunders, many legacy companies have failed because they lack the front end management and technology systems that allow for a continuous flow of new products, processes, or services that outperform their competitors. Many had great beginnings and now have questionable futures. He discusses the development of a model for continuous innovation has been developed from a variety of sources, where TRIZ plays a critical role.

Abstract
Why have many legacy companies been unable to innovate continuously? A study of several famous companies that have stumbled in innovation reveals that it is not just one activity but a multitude of them that are not executed well. That is why "if it were easy everyone would be doing it." Innovation has been defined as invention brought to the market. The federal government has tried to measure innovation and found it very difficult. Work is ongoing to collect information on important factors for innovation but most measure factors that are results versus critical skills that drive innovation. A model for continuous innovation has been developed from a variety of sources, including the author's 40 years in the appliance industry. The model incorporates four key parts and arguably the most important part is problem solving and problem identification. This is where TRIZ plays a critical role since problems poorly solved or not solved lead to weak invention and innovation that can be trumped easily. The details of the model will be explained with associated forms that are useful for implementation.

Enhancing Air Safety for Pilots and ATC using TRIZ

Air Safety is a term embracing the concepts, theory, investigation and categorization of flight failures, and the prevention of such failures through regulation, education and training. The Pilots and Air Trac Controllers (ATC) face a whole panoply of critical decisions during the flight, and most of them are taken within split second under stressful situations. The displays of cockpit and ATC and design of cockpit, are very crucial factors for successful flights. The pilot and ATC face lot of conflicts while performing their roles. The need to display more information conflicts with the focus needed for flying. The vital information needs to be segregated from the routine information. The need to have more switches to control the aircraft conflicts with the operational e ectiveness. This article explores the use of TRIZ principles for resolution of some of these conflicts in order to enhance the Air Safety.

Optimization of a Diesel Engine Software Control Strategy

This paper discusses optimization of software control strategy for eliminating “hitching" and “ringing” in a diesel engine powertrain. Slow- and high-amplitude oscillation of the entire vehicle powertrain under steady pedal position at idle is called "ringing," and similar behavior under cruise-control conditions is called "hitching." The intermittent nature of these conditions posed a particular challenge in arriving at proper design alternatives.

Zero-point-proportional dynamic S/N ratio was used to quantify vibration and tracking accuracy under six driving conditions, which represented noise factors. An L18 orthogonal array explored combinations of six software strategy control factors associated with controlling fuel delivery to the engine. The result was between 4 and 10 dB improvement in vibration reduction, resulting in virtual elimination of the hitching condition. As a result of this effort, a 12 repair per thousand vehicle reliability (eight million dollar warranty) problem was eliminated.

The Robust Design methodology developed in this application may be used for a variety of applications to optimize similar feedback control strategies.

Contradictions Beget Conflicts

In this article by our contributor Aditya Bhalla, he focuses on the contradictions that life constantly places in front of us.

Many people when faced with conflicting demands, whether in personal or professional life, tend to react in one of the two ways
a)      Push through a solution that suits the personal interests (My way or the Highway)
b)      Settle for compromises or tradeoffs

For those who are unskilled in the principles of resolving contradictions, conflicting demands are one of the unfair aspects of life and tradeoffs are the harsh reality to avoid conflicts.

LG case study for making shrinking tubes

Since 2001, LG Cable has tried to enhance R&D processes and manufacturing processes by applying TRIZ. Therefore, LG Cable opened TRIZ education course and have taught full process of TRIZ to research engineers. And TRIZ has been adapted to practical engineering projects.
Several successful results were achieved through co-work with TRIZ team and research engineers. For instance, the quality of Polymer Insulator and Heat Shrinkable Tube were improved dramatically. The tolerance of Heat Shrinkable Tube was relatively more than 7mm and the production speed was limited by the tolerance. Some solutions which satisfy production speed and quality were developed by TRIZ. And the tensile strength of Polymer Insulator was increased by TRIZ, too.
 
In this paper, TRIZ applications and activities in LG Cable will be discussed with example of Heat Shrinkable Tube and full processes.

 Embrace Constraints to Innovate

 

Constraints are Omnipresent.  Many times Problem solvers feel dejected when faced with innumerable constraints. Psychologically it may even trigger thoughts along the lines: “Why me?”

But history is replete with examples of innovators not allowing their innovative spirit to be broken by the constraints. Through their never-say-die spirit coupled with a systematic thinking framework they are eventually able to come out on top of the situation.

Strong innovators have a well developed skill called Perspectives Thinking.

Perspectives thinking is the ability to appreciate the concerns of key stakeholders and their inter-linkages within the context of the given situation. It is also the ability to foresee and adapt to the dynamic nature of those perspectives over time.

Lack of a well developed skill of perspectives thinking leads to situations where the untrained minds gloss over the different and sometimes differing perspectives.
