Solution Approach 1:

The patent uses a two-dimensional printed representation of a human torso instead of a three-dimensional mannequin. The printed image includes visual guidance markers and conductive paths that replicate the essential training function without the complexity of physical mannequin structures. This copying approach maintains measurement precision for electrode placement verification while dramatically reducing device complexity.
