40 Inventive Principles
Shift to Another Dimension

a) Resolve problems which result from the linear movement of an object by allowing two-dimensional movement. Analogous to this, problems with moving or placing objects in a two-dimensional plane are resolved by a transition to a three- dimensional space.

b) Use a multi-layered assembly or structure instead of a single layer.

c) Tilt the object or lay it on its side.

d) Use the reverse side of the object.

e) Use the light or the radiation falling on the reverse side of the object or within its environment.

  1. To produce accurate cuts in fibre-reinforced materials, the teeth of the saw blades are arranged in two rows at different heights. Furthermore, the upper row of teeth has a different pitch to the lower one.
  2. The effective area of a continuous loop (e.g. sanding belt or magnetic tape) is doubled if it is turned into a Mobius strip: the continuous loop is cut, one end is turned 180° and the ends are connected again.
