Sometimes when looking at problems or searching for innovation, it is a handicap to have too much knowledge of the context of the problem.

For example, if you give the problem of spanning a river to a bridge-builder, you will get a bridge as the solution.  It might be a great-looking bridge and/or one with little bits of innovative engineering, but it will not be too dissimilar from past bridges. The advantages are that it will almost certainly be buildable and stable. 

If you give the same problem to a design student with  little or no engineering knowledge, you might get a fabulous, innovative design which looks little like any existing bridge.  It might be unworkable, unbuildable and even dangerous if it were built but it will look- and perhaps – act differently. 

If you combine the talents of a great designer with a great bridge-builder, you will perhaps get the best of both worlds – an innovative deign that is buildable and will prove effective in use.

The ‘ignorance’ of the designer is tempered by the ‘knowledge and skills’ of the bridge-builder.

This is true in other walks of life snd areas of technology – creative people ignorant of the technology can come up with idea which  someone with the appropriate knowledge and skills can turn into a workable solution without losing too much of the innovation snd flair of the original deign.

Ignorance can result in creativity.
