What is an Inventive Problem?
There are two groups of problems people face: those with generally known solutions and those
with unknown solutions. Those with known solutions can usually be solved by information found in
books, technical journals, or with subject matter experts. The other type is called an
inventive problem.
|
New Knowledge |
New knowledge applied to known problems.
Example: New plastics provide strong, lightweight products. |
New knowledge applied to new problems.
Example: Various uses for lasers (surgery, etc). |
|
Existing Knowledge |
Existing knowledge applied to known problems.
Example: All tasks with generally known solutions. |
Existing knowledge does not provide satisfactory solution.
We are dealing with an
inventive problem |

|
Known Problem |
New Problem |
An inventive problem is a problem that:
- Suggests no known means for solution
- Is especially prone to psychological inertia
- Involves one or more contradictions. A contradiction is a situation where an
attempt to improve one feature of the system leads to the degradation of another feature.
