TIRZ Chapter 1 Flashcards
(34 cards)
Q: What does TRIZ stand for?
A: “Theory of Inventive Problem Solving” (Russian acronym).
Q: Core goal of TRIZ in one sentence.
A: Systematically guide engineers to inventive, high-ideality solutions by mining past knowledge.
Define ideality in TRIZ.
Ideality = ALl benefits/(All Costs + All Harms)
Q: TRIZ tool that maps how systems evolve toward increasing ideality.
A: Eight Trends of Evolution.
Q: What is psychological inertia?
A: Mental habits that prevent seeing creative solutions; TRIZ tools help overcome it.
Q: Tool that lists 40 generic ways to resolve contradictions.
Q: Tool that lists 40 generic ways to resolve contradictions.
Q: What are 9-box (Thinking in Time and Scale) maps for?
A: Visualize the problem before/now/after × subsystem/system/supersystem.
Q: Name the TRIZ tool that groups scientific & engineering effects for quick use.
A: Effects database (questions/answers).
Q: TRIZ method of trimming means what?
A: Removing or substituting components to simplify and cut cost.
Q: Function analysis does what?
A: Maps interactions between system components to spot useful vs. harmful functions.
Q: Substance-field analysis purpose?
A: Model system as substances + fields to choose standard solutions.
Q: Trigger: X-Factor.
A: Imagine a magic entity that solves the problem, then back-engineer it.
Q: Trigger: Ideal Outcome.
A: Visualize a solution that eliminates the problem completely.
Q: Trigger: Bad Solution Park.
A: List every terrible idea—often sparks good ones.
Q: Trigger: Smart Little People (SLP).
A: Picture tiny beings acting out each system element.
Q: Trigger: Subversion (Inversion).
A: Try the opposite of standard practice.
Q: Trigger: Size-Time-Cost extremes.
A: Exaggerate each dimension (huge / tiny, instant / slow, free / expensive).
Q: Trigger: Prism of TRIZ.
A: Check if another field already solved a similar essential problem.
Q: Trigger: Life-and-Death analogies.
A: Borrow solutions critical in other domains (e.g., medical).
Q: Trigger: Combine all the good.
A: Merge best parts of many partial solutions (carrot-cabbage analogy).
. Benefits of TRIZ
Solve problems quickly and systematically.
Pool team knowledge effectively.
Increase system ideality (lower cost, remove harm).
Use cheap or existing resources for clever fixes.
Provides structured brainstorming even for TRIZ newcomers.
Limitations (What TRIZ can’t do)
Q: Can TRIZ solve every problem automatically?
A: No—it offers triggers; still requires creative human leaps.
Q: Does TRIZ replace brain-power?
A: No—it shrinks but doesn’t eliminate the creative gap.
Q: Does TRIZ tell which tool to use when?
A: Users must learn tools and select intelligently.
