1. In the first case, your idea is right, and the lower concept destroys the novelty of the upper concept (assuming that the controlled object is in the front)
2. In the second case, it can't be collected, and it is obvious that iron can conduct electricity, which is not creative, but novel. If the metal of the accused plays other roles besides conducting electricity, such as strengthening, discharging arc, etc., at this time, I think there is no infringement.
I want to discuss the above opinions with you.
