Abstract:
Although a bigger keyboard is often comfortable to work
with, they cannot be fit into laptop and small size computer boxes. The portable
and handheld computers need small size keyboards. So there is a need to reduce
the size of the keyboard to fit into the laptop box. There are various
mechanisms to reduce the size of the keyboard; collapsible keyboard is one of
them.
Although different inventions intend to achieve the same
objective of reducing the keyboard size, they all differ in their mechanism.
For example, some invention uses a compression mechanism, some invention uses a
folding mechanism, and some invention uses a collapsing mechanism and so on.
This article illustrates 10 inventions on collapsible keyboards from US patent
database. Each case is analyzed from a TRIZ perspective.
