But that’s not a helpful timeframe. ;-)
Initial research can define the problem space: the breadth and variety of the human problems you are trying to address. An understanding of the limitations of your chosen technology and your business objectives will define your design space. By having an understanding of both will let you know how “narrow minded” you are being.
In other words, if you do some good solid requirements gathering research to start off with, you will have a better idea of how many ideas/sketches you need to work with. But there is no absolute answer. Design is a wicked problem.
