Morphology
The sense 'to have an effect on, especially a negative one' is directly built from the verb 'impinge' (to produce an effect/influence) with the preposition 'on' marking the target. This follows a common verb + on compositional pattern rather than an idiomatic shift, so a B1 learner who knows both constituents should be able to infer the meaning.
Etymology
Impinge on comes from an old word that meant 'to strike against.' Imagine a small particle suddenly hitting a sensor or a meteor striking the ground, and that sharp picture explains why it means 'to hit or come into sudden contact with'.
