Stereotyping is automatically placing value on Saturation Is when the mind subconsciously ignores
something, seeing what you expect to see. sensory inputs because they are familiar sights
Failure to utilise sensory inputs
People that have normal vision rely heavily on their vision and often ignore their other senses.
Bugs are mental walls created by learned, cultural or Daydreaming
environmental standards Intuition and feeling are “bad”
Traditions oppose change
Assigned cultural and social values
The Brainstorming Method
To generate lots of new ideas and solutions, not for analysis or decision making. Should be on a specific/well defined
problem/topic rather than a general problem. Problem definition should not suggest the solution and you should
check whether you really need a brainstorming session on the given issue. Do not plan a brainstorming session if you
already have some possible solutions.
The Ideal Final Result Method
a) The object (or its element)
c) Certain function
d) By itself, without our direct involved
f) In what circumstances? (Or under what restrictions?)
The method of “Dwarfish People” modelling (smart little people modelling)
Pretend like there are little people doing the jobs required and see element can be put in their place to make the
The morphological box method
1) Formulation of the problem to be solved. General description of the object to be investigated.
2) Revealing of important characteristics and properties of the object
3) Investigation of possible variants of obtaining of each characteristic (property, function)
4) Matching variants in morphological ma
