The Oxford TRIZ Standard Solutions

The Oxford TRIZ Standard Solutions are a powerful tool for dealing with problems: they are simple lists of solutions based on analysis of patents and scientific journals. They are organised according to the kind of problem they solve:

• Dealing with harm (H)
• Overcoming insufficiency (i or i.a.)
• Difficulties with measuring and detecting (M)

The Standard Solutions are numbered in a logical way. Each Standard Solution has both one or two letters and two numbers: the letter tells you the class of the Standard Solution (such as H for ‘harm’); the first number tells you the category of Standard Solution (for example, 2 for ‘Block the harm’), the second number identifies the specific Standard Solution (such as ‘protect part of the system from harm’).

• Dealing with Harm
  1. H1 = Trim out the harm (6 solutions, so H1.1, H1.2 and so on until H1.6)
  2. H2 = Block the harm (11 solutions)
  3. H3 = Turn harm into good (4 solutions)
  4. H4 = Correct the harm afterwards (3 solutions)
• Overcoming Insufficiency
  1. i1 = Add something to the subject or object (7 solutions)
  2. i2 = Evolve the subject and object (10 solutions)
  3. i.a. = Improve the action (18 solutions)
• Difficulties with Measuring or Detecting
  1. M1= Indirect methods (3 solutions)
  2. M2 = Add something (4 solutions)
  3. M3 = Enhance measurement with fields (3 solutions)
  4. M4 = Use additives with fields (5 solutions)
  5. M5 = Evolve the measurement system (2 solutions)
