I think the key is being able to genuinely relax from focusing on the problem to help your thinking. To allow an opportunity for those competing thoughts that aren't making it to your awareness because they are beaten by whatever train of thought you are stuck on. Little rituals like taking a shower (or sitting on the toilet is a popular one) distract you so you can relax. Or they should. If it isn't working for you maybe you are too good as staying focused and aren't getting the benefit from relaxing. Thinking about work while walking would defeat the purpose.
