If there is a SFM which is not easy to change as required, and the conditions contain restrictions on the introduction or attachment of substances, the problem has to be solved by synthesizing a SFM using external environment as substance.

If the external environment does not contain ready substances required to synthesize a SFM by 1.1.4 rule, these substances can be obtained by replacing the external environment with another one, or by decomposing the environment or by introducing additives in it.

If a minimum (i.e., measured, optimal) mode of action is required, but it is difficult or impossible to provide it under the conditions of the problem, one should use a maximum mode, while the surplus of the action is then removed. The surplus field can be removed by a substance, ...

If a maximum mode of action on a substance is required but this is not allowed for some reason, the maximum action should be maintained but directed to another substance attached to the first one.

If a selective-maximum mode is required (maximum in certain zones while the minimum mode is maintained in other zones), the field should be maximal.

If a useful and a harmful effects appeared between two substances in a SFM and it is not required that these substances be closely adjacent to one another, the problem is solved by introducing a third substance (available or cheap) between these two substances.

If there are a useful and harmful effects between two substances and it is not required that these substances be closely adjacent to one another, but it is forbidden or inconvenient to use foreign substance, the problem is solved by introducing a third substances (modification of the existing substances) between ...

If it is required to eliminate the harmful effect of a field to a substance, the problem is solved by introducing a second substance that "draws off" the harmful effect of a field.

If a useful and harmful effects appear between two substances in SFM, and a direct contact between the substances (in contrast to Standards 1.2.1 and 1.2.2) must be maintained, the problem is solved by transition to a dual SFM in which the useful effect remains with the given field (F1) ...

If it is necessary to decompose a SFM with a magnetic field, the problem is solved by using physical effects, "turning off" ferromagnetic properties of substances, e.g. by demagnetizing during an impact or during heating above Curie point.

If it is necessary to increase efficiency of SFM, the problem is solved by turning on of the parts of the SFM into an independent controllable SFM and forming a chain SFM.

If it is necessary to increase the efficiency of a controlled SFM, and replacement of SFM elements is prohibited, the problem is solved by the synthesis of a dual SFM by applying a second, easy to control field.

Efficiency of a SFM is enhanced by replacing an uncontrollable (or poorly controlled) working field with a controllable (well-controlled) field, e.g. by replacing a gravitation field with a mechanical one, a mechanical field an electric one, etc.

Efficiency of a SFM is enhanced by transition from a solid substance to a capillary porous one. Transition to a capillary porous substance enables a liquid substance to be placed in the pores and physical effects to be used.

Efficiency of SFM is enhanced by transition from uniform field or fields with a disordered structure to non-uniform field or fields with a definite spatial-temporal structure (constant or variable).

Efficiency of a SFM is enhanced by transition from substances that are uniform or have a disordered structure to substances that are non-uniform or have a predefined spatial-temporal structure (constant or variable).

Efficiency of a SFM is enhanced by matching (or specially mismatching) the frequency of fields action with the fundamental frequency of a product (or tool).

Efficiency of complex SFM is enhanced by matching (or specially mismatching) frequencies of the fields being used.

If two actions are incompatible, e.g. treatment and measurement, one action should be performed during the pauses in another one. Generally, pauses in one action should be filled with another useful action.

Efficiency of a SFM is enhanced by using a ferromagnetic substance and a magnetic field.

Efficiency of control over a SFM is enhanced by replacing one of the substances with ferromagnetic particles (or adding ferromagnetic particles) – chips, granules, grains etc. – and using a magnetic or electromagnetic field.

Efficiency of ferromagnetic SFM is enhanced by transition to the magnetic fluids – colloidal ferromagnetic particles suspended in kerosene, silicone or water.

Efficiency of ferromagnetic SFM is enhanced by using capillary porous structure (CPS is common for feSFMs).

If it is required to improve efficiency of system control, and replacement of substances with ferromagnetic particles is prohibited, the transition is to be performed by forming an internal or external complex ferromagnetic SFM, introducing additives in one of the substances.

If it is required to increase efficiency of system control, and replacement of substances with ferromagnetic particles is prohibited, the ferromagnetic particles should be introduced in the external environment and, using the magnetic field the environment parameters can be changed and the system (inside environment) therefore can be controlled (Standard ...

Controllability of a ferromagnetic system is enhanced by the applying the physical effects.

Efficiency of feSFM is enhanced by increasing the degree of dynamism, i.e. by transition to more flexible, rapidly changing structure of the system.

Efficiency of feSFM is increased by transition from fields that are uniform or have a disordered structure to fields that are non-uniform or have a definite spatial-temporal structure (constant or variable).

Efficiency of a ferromagnetic SFM is increased by matching the rhythms of the system's elements.

If it is difficult to introduce ferromagnetic or to perform magnetization, one should go over to an eSFM using interaction of an external electromagnetic field with currents either fed through a contact or induced without a contact, or using interaction between these currents.

If a magnetic fluid cannot be used, the electrorheologic fluid may be usefull.

System efficiency at any stage of its evolution is enhanced by combining it with another system (or systems) to form a more complex bi- or poly-system.

If it is given the problem of detection or measurement and it is impossible to change technical system such that there should be no need to perform detection or measurement (Standard 4.1.1), it is proposed to replace direct operations on the object with operations on its copy or picture.

If it is given the problem of measurement and it is impossible to apply Standards 4.1.1 or 4.1.2, it is proposed to transform the problem into the one of sequentially detection of changes.

If a non-SFM is not easy to detect or measure, the problem is solved by synthesizing a simple or dual measuring SFM with a field at the output. Instead of direct measurement or detection of a parameter, another parameter identified with the field that is measured or detected.

If a system (or its part) does not to provide detection or measurement, the problem is to be solved by going over to an internal or external complex measuring SFM, by introducing easy-to-detect additives.

If a system is difficult to detect or to measure at a given moment on time, and it is impossible to introduce additives in the object, the problem is to be solved by introducing needed additives (creating an easy-to detect and measure field) in the external environment, whose changing state ...

If it is impossible to introduce easily detectable additives in the external environment (by rule 4.2.3), the problem is to be solved by obtained needs in the environment, e.g. by decomposing it or by changing its aggregate state.

Efficiency of measuring SFM is improved by the use of physical effects.

If it is impossible to detect or measure directly the changes in the system, and no field can be passed through the system, the problem is to be solved by existing resonance oscillations (of the whole system or of its part), whose frequency change is an indication of the changes ...

If resonance oscillation may not be excited in a system (it is difficult to use Standard 4.3.2), its state can be determined by a change in the natural frequency of the object (external environment) attached with the system.

Efficiency of measuring SFM is improved by using a ferromagnetic substance and a magnetic field.

Efficiency of detection or measurement is improved by transition to ferromagnetic SFMs, replacing one of the substances with ferromagnetic particles (or adding ferromagnetic particles), and by detecting or measuring the magnetic field.

If it is required to improve the efficiency of detection or measurement by transition to a ferromagnetic SFM, and replacement of the substance with ferromagnetic particles is not allowed, the transition to the feSFM is performed by synthesizing a complex ferromagnetic SFM, introducing (or attaching) ferromagnetic additives in the substance.

If it is required to improve the efficiency of detection or measurement by transition to a ferromagnetic SFM, and introduction of ferromagnetic particles is not allowed, ferromagnetic particles are introduced in the external environment.

Efficiency of a feSFM measuring system is improved by the use of physical effects, such as going through Curie point, Hopkins and Barkhausen effects, magnetoelastic effect, etc.

Efficiency of a measuring system at any stage of its evolution is improved by forming bi- or poly-system.

Measuring systems evolve towards measuring the derivatives of the function under control.

If a system is not easy to change as required, and the conditions do not allow to replace the component acting as tool or introduce additives, the product has to be used instead of the tool, dividing the product into parts interacting with each other.

After the substance introduced in the system has fulfilled its function, it should either disappeared or became indistinguishable from the substances that was in the system or in the external environment before.

If it is necessary to introduce a large quantity of substance, but this is not allowed, a "void" in the form of inflatable structures or foam should be used as the substance.

If a field has to be introduced in a SFM, one should use first of all the present fields for whom the media are those substances that form the system.

Efficiency of the use of substance without introducing other substances is improved by changing its phase.

"Dual" properties are provided by using substances capable of converting from one phase to another according to operating conditions.

Efficiency of system can be improved by the use of physical phenomena accompanying a phase transition.

"Dual" properties of a system are provided by replacing a single-phase state of the substance with a dual-phase state.

Efficiency of systems obtained as a result of replacing a substance's single-phase state with a dual-phase state is improved by introducing interaction (physical or chemical) between parts (phases) of the system.

If an object is to be alternating between different physical states, the transition is performed by the object itself using reversible physical transformations, e.g. phase transitions, ionization-recombination, dissociation-association, etc.

If substance particles (e.g. ions) are required to solve a problem and they are not available according to the problem conditions, the required particles can be obtained by decomposition a substance of a higher structural level (e.g. molecules).

If substance particles (e.g. molecules) are required to solve problem and they can not be produced by decomposing a substance of a higher structural level, the required particles can be obtained by completing or combining particles of lower structural level (e.g. ions).

If a substance of a higher structural level has to be decomposed, the easiest way is to decompose the nearest higher element. When completing or combining particles of a lower structural level, the easiest way is to complete the nearest lower element.
