Separation in Time

I want the (pile) to be (sharp) while(driving). I want the (pile) to be(blunt) while (supporting). Mustthese critical conditions overlap intime? No, they do not have tooverlap. Therefore we canseparate in time.

Some stages performed in advance

Prior Action

Partial Action

Part of whole action performed in advance

Rest of whole action performed when required

The contradiction attribute relates to an action orfunction that must be performed rapidly and slowly.The function of (painting) the (detailed parts) can berapidly performed by the gross action of (painting with aroller or large brush). The detailed remedial action of(removing the excess paint) is made possible by(applying masking) in advance or by overflowing a(hydrophobic) threshold by (making the unpainted areasfrom hydrophobic materials.)

Then

Too Much

Perfect

First

The contradiction is an action or function. (Tearing) ofthe (towel) can be broken down into steps. The stepsof (holding and tearing) are performed during (any timeprevious to use) by (mechanical holding and tearing) inorder to have (tearing). The remaining steps of (pullingthe towel) are performed during (towel use) in order tohave (not tearing).

Test for Separation in Time

The contradiction attribute relates to an action orfunction. (Tearing) of the (towel) is partiallyperformed in its entirety during (manufacture of thetowel) by (perforating the towel) giving (not tearing).The function is completed during (towel use) by(pulling the towel) giving (tearing).

Excessive and Remedial Action

ThenFirst

High High

Null

The harmful function of (tension loading) the (concretespan) cannot be avoided. The counter action of (applyinga compression load) is performed in advance by (insertingsteel columns under tension which “clamp” the span) sothat when the time comes for the harmful action of(tension loading) the (concrete span) it is not (tensionloaded).

Prior Counter Action

High High

Stable

HighCounterWeight

The contradiction attribute relates to an action orfunction. The (weight) must be (null action—stable)during (positioning). This is accomplished by applying (acounter weight or force). The counter action is removedduring (dropping) when the full action is required.

Countering

High Transmission

First Condition

Separation on Condition

The difference of (light intensity) between (low lighting)and (intense lighting) will change the (glass’s lighttransmission) from (high transmission) to (lowtransmission). The (photo sensitivity) will be exploited todrive the change of parameters.

Separation on Condition-

TransparencyThe difference of (inertia of force) between (largeobjects) and (small objects) will change the (separatormaterial) transparency from transparent to opaque.The (inertia or relative force) will be exploited to drivethe change of parameters.

The (voice) to be operated upon must be (male) during(actual story telling). A transformation of (voicemodulation) changes the (voice) to (female) during(transmission of the show).

Low Drag

The (air brake) is formed from (fabric). The (air brake)is (compacted) during (freefall), thus making it (lowdrag). The (airbrake) is (expanded) during (braking),thus making it (high drag).

During (engraving) (tar) which is (stiff) is (attached to,surrounding or mixed with) (individual or segmented)(plates) which are (flexible) thus loaning its propertyand making the combination (stiff). No carrier is usedduring (forming the plate) making the (plate) (flexible).

Segmentation is (allowed and accomplished bydesigning the table as separate pieces or not allowed).During (use) several (segmented or individual) (tablepieces) have the property of being (massive) whileunified or interacting through (an interlocking table orfastening elements). During (transportation) the unifyinginteraction is absent making them (light).

Merging—Countering sharp sharp

Elements are configured, oriented or designed to oppose eachother by (orienting them to oppose each other). Separating the(piles) during (driving) makes them (sharp). During (supporting)the merged (piles) oppose each other making them (blunt).

Multiple (thrusters) are available for adjustable use. During(large payloads) many (thrusters) are used to give (highthrust). During (small payloads) few elements are used togive (low thrust).

materials

The response of (field region A or field A) to (material,coating or structure) is (setting A). The response of(field region B or field B) to (material, coating orstructure) is (setting B).For Example:The response of (visible light) to (glass) is(conducting). The response of (ultraviolet light) to(glass) is (non-conducting).

Separate by Response of Fields

The field element associated with the conflict is (amagnetic field). The substance element associated withthe conflict is (the field coils). The (magnetic field) is(rotating) and the (coils) are (stationary). This isaccomplished by (switching on the coils in apredetermined sequence. The magnetic field directionappears to rotate, depending on the sequence of theswitching).

Compensate

Turn a knob sufficiently to fix the given problemwithout regard for what gets worse.Identify another knob which can be turned whichcompensates for the first one turned.
