TRIZ is a brilliant toolkit for nurturing engineering creativity and innovation. This accessible, colourful and practical guide has been developed from problem-solving workshops run by Oxford Creativity, one of the world's top TRIZ training organizations started by Gadd in 1998. Gadd has successfully introduced TRIZ to many major organisations such as Airbus, Sellafield Sites, Saint-Gobain, DCA, Doosan Babcock, Kraft, Qinetiq, Trelleborg, Rolls Royce and BAE Systems, working on diverse major projects including next generation submarines, chocolate packaging, nuclear clean-up, sustainability and cost reduction. Engineering companies are increasingly recognising and acting upon the need to encourage successful, practical and systematic innovation at every stage of the engineering process including product development and design. TRIZ enables greater clarity of thought and taps into the creativity innate in all of us, transforming random, ineffective brainstorming into targeted, audited, creative sessions focussed on the problem at hand and unlocking the engineers' knowledge and genius to identify all the relevant solutions. For good design engineers and technical directors across all industries, as well as students of engineering, entrepreneurship and innovation, TRIZ for Engineers will help unlock and realise the potential of TRIZ. The individual tools are straightforward, the problem-solving process is systematic and repeatable, and the results will speak for themselves. This highly innovative book:
• Satisfies the need for concise, clearly presented information together with practical advice on TRIZ and problem solving algorithms
• Employs explanatory techniques, processes and examples that have been used to train thousands of engineers to use TRIZ successfully
• Contains real, relevant and recent case studies from major blue chip companies
• Is illustrated throughout with specially commissioned full-colour cartoons that illustrate

Meet the Author

Karen Gadd has been teaching TRIZ and problem solving withengineering teams from major companies for over 13 years. Hermission is to make TRIZ learning straightforward and the TRIZ Toolseasy to use. She has worked on nothing but TRIZ since discoveringand learning its power to give us all the routes, to all thesolutions, to all engineering problems.
In 1998 Karen started Oxford Creativity to concentrate ondeveloping simple and practical TRIZ problem solving for theEuropean market. Karen has taken TRIZ to major companies includingRolls-Royce, British Nuclear Group, Bentley Motors, BAE Systems,Nissan, Pilkington, Borealis and Sanofi Aventis. Oxford Creativityis now well established as one of the world's top TRIZ companiesand has helped to make TRIZ well known and widely used throughoutEurope and encouraged top companies to create expert TRIZ teams forinnovative problem solving.
Karen studied Mechanical Engineering at Imperial College, and hasan MBA from London Business School. After working in strategy andcorporate planning in the City of London she returned to live inOxford and was a tutor at Oxford's Business School the EuropeanSchool of Management ESCP-EAP (based in Paris, Oxford, Madrid andBerlin). From 1995-2002 she was a Governor of Coventry University.Karen's career has been dedicated to creating new enterprises whichmake a difference - she founded both MUSIC at OXFORD and theEuropean Union Baroque Orchestra and ran both for over ten yearsand raised millions in corporate sponsorship to make theiractivities possible. These successful music organisations stillflourish. MUSIC at OXFORD transformed Oxford's music scene and isnow approaching its 30th season of top professional classicalconcerts. EUBO has celebrated 25 years of launching the careers oftalented young musicians and has been so successful in its mission,that there are now former EUBO students in every major professionalbaroque ensemble in the world. Karen launched Oxford Creativity tomake TRIZ accessible to everyone and transform and launch careersof TRIZ enthusiasts and champions. There are now thousands ofengineers who have learned TRIZ from Karen and who intelligentlydaily apply TRIZ to solve difficult technical and scientificproblems.
Karen is long married, has four children and three grandchildrenlives happily in Oxford and the Lake District. Karen has recentlybecome a director of the Orchestra of St.John's and concerts andsinging are still part of her interests and activities.

    A modern textbook on TRIZ, highly recommended.

    I liked TRIZ for Engineers. As a practicing engineer for 20 years, and as a student of TRIZ for five years, I have read a wide range of text on classical TRIZ and higher levels of TRIZ approaches used in inventive problem solving. The book presents real engineering problems in short form scenarios and through case studies that include detailed notes on how to use a range of TRIZ tools to generate solutions. The example problems are engineering based, but less industrial focused, so the examples have a wide application to the engineering market and technologist new to the basic TRIZ concepts. .The book offers problem solving maps and algorithms that illustrate how the TRIZ tools presented in the chapters can combine to form larger algorithms. The solution maps present through out the chapters flow through the early phases of developing a problem statement, identifying which TRIZ tools fit the problem scenario and onward to developing and applying solutions. The book also offers color figures and tables, which compliment the text as it illustrates how TRIZ is used to model systems and analyze functions. Thematic cartoons are included, as the author notes to bring some levity to the educational process. In my opinion, the cartoons present a physical contradiction as a reader, as they both add and distract from the text and the more formal diagrams and figures. .The author emphasizes that TRIZ is a set of tools, which can offer more than one solution to a problem and that all solutions have some level of merit based on the users needs. This perspective is well supported in the book's classical TRIZ modeling examples. The later chapters include examples of the Traditional TRIZ 76 Standard Solutions, Substance-Field modeling, and ARIZ, which adds clarity to modeling problems with higher-level TRIZ tools. These advanced concepts discussions are supported with case study based examples. The book offers illustrations of blank worksheets that students can use as a reference to help analyze and execute the book's algorithms while problem solving. There are also chapters describing how the TRIZ concepts can be used to analyzing trends and inventing with TRIZ beyond the basic problem solving. .The best part of the book from my perspective is the text-based descriptions of creating a functional analysis model and developing solutions through trimming and substitution of the functional models. I complement Karen Gadd on her efforts to bring TRIZ to engineers, and will recommend the book to TRIZ novices and more experienced inventive problem solvers.
