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.
