The claims of an apparatus or device include the elements or parts that when arranged together makes that apparatus or device. For example, in case of electric brush, the elements or parts such as a battery (power source), a motor (that drives the bristles), bristles, handle etc. should be claimed. These elements or parts are not available in a non-electric brush and therefore the claims of electric brush is different from the non-electric brush. It does not matter if both of them solves the same problem i.e. cleaning teeth. Many different solutions (patents) can solve the same problem.
