Easy way of finding new thing by going in reverse process

In order to find new things happening around us ,there is a way of doing thing and finding new.The IDEA is,Rather doing things in conventional way there is a new way for doing things like-by doing things in unconventional way,we can find NEW thing do going through the process in UNCONVENTIONAL way.

For example:Y do banks don't provide service at night hours.......

If we go through this way i hope that we can find things easy to find NEW out of it
