Ein Kern TRIZ Instrumentarium zur Lösung technischer Widersprüche, bei denen die Verbesserung eines Systemparameters einen anderen verschlechtert: Die 40 Prinzipien sind generische Erfindungsstrategien, die sich aus Folgendem ableiten: Patent Die Widerspruchsmatrix ist eine Tabelle, die Standardparameter der Ingenieurwissenschaften einander gegenüberstellt und aufzeigt, welches der 40 Prinzipien am ehesten eine Lösung für einen bestimmten Konflikt bietet.

The 40 Inventive Principles and the Contradiction Matrix are foundational elements of classical TRIZ, developed by Genrich Altshuller and his colleagues after analyzing over 40,000 patents. They observed that the same fundamental problems and solutions appeared across different fields of technology. The core idea is to systematically overcome ‘technical contradictions’. A technical contradiction occurs when an attempt to improve one characteristic of a system (e.g., speed) leads to the degradation of another (e.g., reliability).

Altshuller identified 39 standard system parameters, such as ‘Weight of moving object’, ‘Strength’, ‘Temperature’, and ‘Productivity’. The Contradiction Matrix is a 39×39 grid where the rows represent the parameter to be improved and the columns represent the worsening parameter. At the intersection of a specific row and column, the matrix provides numbers corresponding to the most frequently used Inventive Principles for that type of contradiction in the patent database. For example, to solve a contradiction between ‘Strength’ (improving) and ‘Weight of stationary object’ (worsening), the matrix might suggest principles like #1 (Segmentation), #10 (Preliminary Action), or #40 (Composite Materials). The principles themselves are abstract heuristics, such as ‘Segmentation’ (divide an object into independent parts), ‘Asymmetry’ (make an object asymmetrical), or ‘Universality’ (make a part perform multiple functions). This structured approach transforms a specific, difficult problem into a general problem, finds a general solution using the principles, and then adapts that general solution back to the specific context, bypassing psychologische inertia and trial-and-error.

Potenzielle Innovationsideen

  • an ai-driven TRIZ system that automatically identifies contradictions in CAD models and suggests principle-based design changes
  • applying the contradiction matrix to resolve conflicting goals in sustainable urban planning (e.g., density vs. green space)
  • developing new business models by resolving market contradictions (e.g., premium quality vs. low cost) using the principles
  • creating adaptive Cybersicherheit protocols that resolve the conflict between security level and system performance
  • designing educational software that adapts to student learning styles by resolving the contradiction between standardized curriculum and personalized pacing
  • optimizing pharmaceutical drug delivery systems to resolve conflicts between efficacy and side effects
  • innovating in food science to create products that resolve contradictions like taste vs. health or long shelf-life vs. natural ingredients
  • designing next-generation user interfaces that solve the contradiction between feature richness and ease of use
  • structuring legal contracts to preemptively resolve conflicts between flexibility and enforceability
  • developing financial products that resolve the contradiction between high return and low risk
