Example on principle #1 "Segmentation":
Pants separable at the crotch into right and left leg portions for style mixing:
Each leg portion is selected from a set of various styles to flexibly create a custom mixed or matched style for a given wearing of the pants. (US Patent #6161223 A.)
Example on "Utilize centrifugal force" (subprinciple #14c of principle #14 "Spheroidality"):
Apparatus for facilitating the birth of a child by centrifugal force (US Patent 3216423). The mother-to-be is strapped onto the turntable, which spins fast enough that centrifugal force helps ease the baby out. A "pocket-shaped reception net" catches the newborn and triggers the machine to stop. (But in case that doesn't work, there's a handbrake!).
Example on principle #18 "Mechanical vibration":
A chair for coition. Provides support for two people, one astride the other. In one preferred form, the seat vibrates (UK Patent Application No. GB2283412):
The invention relates to a novel form of chair. In the past chairs have been constructed with one back rest. Such chairs are ideally suited for one person, but not for two people. If a man and woman wish to have intimate relations on such a chair they face the problem that the woman once astride the man will be unsupported since there is no back supporting section for supporting her back once she is sitting astride the man, facing the man. This makes the act of coition difficult and uncomfortable.
To make the act of coition comfortable a second back rest is added. To further facilitate the act of coition the seat vibrates.
Example on principle #20 "Continuity of useful action":
Kamikaze flying multiple successful missions.
Example on principle #23 "Feedback":
An alarm inside a coffin to guard against premature burials.
Example on principle #29 "Pneumatic or Hydraulic Constructions (e.g. replace solid objects with inflatable ones)":
Inflatable dart board.
Example on "Transparency change" (the subprinciple of principle #32):
Glass bottom boats of a new German navy, to see the boats of the old German navy.
Example on the principle "Linearity/Anti spheroidality":
Two inches high, two inches wide, and fifty feet long box to store a garden hose.
Example on principle #34 "Discarding and recovering":
Well, not quite. The doorknob is not discraded. It rather retracts when the door is locked and extends/resurfaces when it is open. Is it not better to have a separate principle called "Retracting and extending/resurfacing" ?
Example on principle #37 "Thermal expansion or contraction":
Ice filled condom to keep the swelling down.
Example on principle #40 "Composite materials":
Wooden swimsuits (wood is a natural composite material ):
