This final patent, like the others, addresses a problem that virtually everyone who has used a bathroom has encountered.

The invention is not spectacular; it does not require advanced materials science or complex engineering.

But it represents the application of careful thinking to a genuine everyday problem, and in this it is entirely consistent with the pattern of all of Kenner’s inventive work.

Taken together, the five patents represent a remarkable span of inventive achievement.

Kenner invented in multiple product categories — personal care, bathroom products, health and mobility aids, safety products.

She thought across domains rather than specializing in a single area.
