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.

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.

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).

Merging—Adjustable Numbers
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).

Two (piles) which are (sharp) and (blunt) are attached toeach other. During (driving) the pieces are oriented sothat (sharp) comes into play. During (supporting) thepieces are oriented so that (blunt) comes into play.
Rearranging—Changing Directions
Changing directions of the (propeller) allows thesetting to be changed. During (takeoff and landing)the (propeller) is oriented so that (upward lift) comesinto play. During (flying) the (propeller) changesdirection so that (lateral force) comes into play.

the Parts and the WholeStep 1: At a critical moment in time, should either (failed) or (notfailed) be hidden or minimized to solve the problem? Yes, if bulbfailure were hidden it would solve the problem.Step 2: At a critical moment in time, do I want (failed) AND (notfailed) to occur at different scales? No, I do not want a “failed”light to occur at any scale.Step 3: If the answer to 1 or 2 is “yes”, separate between theparts and the whole. The answer to 1 is “yes”.
