ing the 76 standard solutions onto the 40 inventive principles in TRIZ Principle Standard solution

Divide the element into smaller units Use particles instead of the whole object Divide the object into parts, then make it flexible by linking the parts Transition to the micro-level Protect certain regions from the full impact of an action Turn a magnetic field on or off according to the local need. Change from uniform structure to a structure that is specific to the situation Concentrate an additive in one location Change from uniform structure to a structure that is specific to the situation Additive, temporary or permanent, internal or external, from the environment or from changing the environment Simplification of Bi- and Poly-systems

Use a substance to protect a weaker substance from a potentially harmful occurrence.

Introduce magnetic materials in the environment, instead of into the object

Make the system flexible Use dynamic magnetic fields Control small quantities by applying and removing a surplus Simulate the introduction of more than is acceptable

Match the natural frequencies of the field with the substance Use vibration in conjunction with magnetic fields

Measure changes in a system by means of changes in its resonant frequency. Replace an uncontrolled field with a structured one. Use magnetic field resonance Do one operation during the downtime of another

Eliminate harmful effects (also others in 1.2) Self-controlled changes Use dynamic magnetic fields Use one object to make the actions of another possible. Create structures by use of magnetic particles Introduce a ferromagnetic additive, temporarily Use a temporary additive, internal or external Introduce an additive temporarily Measure a copy Self-controlled changes Use dynamic magnetic fields Measure a copy Apply additives to a copy instead of the original Replace or supplement a poorly controlled field with a more easily controlled field Use of ferromagnetism and ferromagnetic materials Use electric current instead of magnetic particles Create a field that can be detected or measured Use a field instead of a substance Use magnetic liquids Use "nothing" Use "nothing" to simulate structures Change from a uniform structure to a structure that is specific to the situation Use porous or capillary materials Change a uniform structure to a non-uniform one

Use capillary or porous structures in a magnetic material, or to contain magnetic fluid Use detection instead of measurement Measure the system by means of natural phenomena The additive disappears after use Phase change Additive, temporary or permanent, internal or external, from the environment or changing the environment Use rheological liquids Use the accompanying effects from phase changes Use the physical effects of magnetic transitions Control a system by means of a phase transition, instead of measuring temperature, pressure, magnetic field, etc. Measure the system by means of natural phenomena Control a system by means of thermal expansion, instead of measuring temperature Measure expansion instead of temperature Getting needed ions, molecules, etc. Includes 5.51, 5.52, and 5.53 Use small amounts of very active additives Additive, temporary or permanent, external Change the environment of the system Add "nothing"—foam, honeycomb, etc.
