TRIZ (Inventive Principles)

Nesting

7: NESTING: (A) Place (embed or position or put or insert) an object (or system) inside another object and so on in a recursive manner, (B) Pass an object (or system) through the cavity of another object (or system). EXAMPLE: Door-within-a-door, Stacked Chairs, Telescoping/Extendable Antenna, Suspended oil storage reservoir (that stores different products in a …

Universality

6: UNIVERSALITY : (A) Make a part or object (or system) perform multiple (several different) functions; thereby eliminating the need for other parts (or elements) or objects (or systems) (B) Introduce or use commonly (widely or universally) acceptable standards. EXAMPLE: Sofa-cum-bed, Cycle-as-Wheelchair, Home-on-Wheels, Houseboat, Toothbrush (with inbuilt toothpaste disposal system in its handle), Child’s Car …

Consolidation

5: CONSOLIDATION: (A) Consolidate homogeneous (identical or related) objects in space or objects destined for contiguous operations or functions,  thereby also decreasing the number of interfaces (to a manageable least limit) (B) consolidate homogeneous (identical, related) or contiguous operations or functions in time (to action or performance together at the same time) SYNONYMS: MERGING, Combining, …

Asymmetry

4: ASYMMETRY: (A) Change or replace symmetrical form (s) with asymmetrical form (s), (B) Vary the degree of asymmetry, if an object (or system) is already asymmetrical, change an object’s (or system’s) or property or form to suit the asymmetry in the external environment EXAMPLE: Electric furnace with asymmetrically placed electrodes, Encryption System, Key- Lock, …

Local Quality

3: LOCAL QUALITY: (A) Change an object’s (or system’s) structure or property from uniform (or homogeneous) to non-uniform (or heterogeneous), (B) Change an object’s (or system’s) external environment from uniform (or homogeneous) to non-uniform (or heterogeneous), Make each (different) part of an object (or system) perform a different useful function, (C) Make a part of an …

Extraction

2: EXTRACTION (TAKING OUT, Extracting, Retrieving, Removing, Separating, Isolating, Zoning Out): (A) Extract the “redundant or disturbing or an interfering” part (or property) of an object (or system), (B) Extract only the “necessary or useful” part (or property) from an object (or system), (C) Extract only the desired (required or non-required) function (in terms of time or …

Oxidation

38: ACCELERATED OXIDATION  : Principle of “strong oxidants” is related to the use of substances with powerful oxidizing properties to address and solve problems in innovative ways. Oxidants are substances that facilitate oxidation reactions, where a substance loses electrons. In inventive problem-solving, this principle considers introduction or utilization of substances with strong oxidizing properties to improve a …
