Action Principle category is used in the following TRIZ tools and stages of TRIZ-based innovation process:
• Trends of Engineering System Evolution ‒ different S-Curves for different Action Principles
• Feature Transfer ‒ integration of two alternative engineering systems with the same function and different Action Principles
Role of Action Principle in TRIZ

Principles• ARIZ step 5.4. ‒ application of “physical effects”• MPV Discovery ‒ product category definition as a group of products with the same main function but different Action Principles
• Function-Oriented Search ‒ first level of search for the best Action Principle that addresses the function
• Idea’s feasibility evaluation

Nine Cornerstones of Systematic Innovation
1. Use a scientific problem solving approach; not just inspiration
2. Innovate against the right product, not every product – “Right Product”
3. Improve only features the customer will pay for, not all features – “Right MPV”
4. Address key problems, not initial problems –“Right Problem”

“Right Problem”
5. Focus on functions, not design components
6. Utilize global knowledge to complement your in-house expertise
7. Adapt existing solutions, don’t always invent
8. Select evolutionary winners, not losers
9. Resolve contradictions, don’t compromise

• Function (F) is an action of one material object that changes (or retains) parameters of the other material object
• Action Principle (AP) is a specific way of changing the functional parameter that actualized the function
Action Principle Definition and Approach

• If an Engineering System has two or more main functions each of them may have different AP
• Complementary functions of the same product may have different AP comparing with main function
• One function may be actualized by a combination of different AP

• It is proposed to consider a Production Process as a combination of different pieces of equipment and transportation means that perform different Functions with corresponding different Action Principles
• Example 2: Production of Low Fat Peanut Butter
Action Principle for Production Processes

- Function – to mix ingredients (to move powder particles relative to highly viscose liquid).- Changing parameter – particles concentration in the volume.- Equipment – auger mixer; disc mill; jet mixer; vibro-mixer

• In many consumer products an Active Agent and Delivery System have different Action Principles
• Example 3: Teeth Whitening System- Active Agent – bleaching gel. Function – change teeth color. Action Principle – chemical oxidization of enamel.

of enamel.- Delivery System 1 – tray. Function – to deliver Active Agent to the teeth. Action Principle –mechanical containing and transportation.- Delivery System 2 – WhiteStrips. Action Principle – osmotic penetration through the membrane.

• A Function can be formulated on a different hierarchical levels
• The higher the level of function the more variety of Action Principles can actualize it and the broader is a field of potential solutions
• Mega-Function – is a generalized Function that
Action Principles for Different Levels of Function

• Mega-Function – is a generalized Function that combines several similar specific functions
• For different specific Functions that are a part of the same Mega-Function Action Principles are also different

• For the same Action Principle it is possible to identify sub-AP

Conclusions:• A clear definition of Action Principle is proposed for
both products and processes basing on functional approach
• Recommendations for Action Principle identification for typical situations were developed
• TRIZ definition of Toll (Working Agent) was clarified
Action Principle: Coclusions

• TRIZ definition of Toll (Working Agent) was clarified basing on a definition of AP
• A well defined Action Principle is making several TRIZ techniques (S-Curve Analysis, TESE, Feature Transfer, MPV Discovery, etc.) more instrumental
• The proposed definition of AP was successfully tested in several practical innovation projects
