Diaper Warning Alarm Device, and System
U.S. Patent Office
An electronic device that alerts you when your child has used its diaper. Unfortunately, it only detects urine or liquid stool. Fortunately, nature has already come up with an alarm system for solid excrement (it's called "farts").
Let's review the elements involved in this invention: Babies. Liquid. Electricity. Yup, there's no way that could ever go wrong. We may be able to consider using this with Grandpa (because he's lived a full life, and each bowel movement is a gamble anyway), but it doesn't look like the proposed size would fit him.
"I'm more of a freeballer anyway."
What's with patent makers trying to reinvent the wheel when it comes to baby defecation? Again, they don't need a lot of help there. Parents can usually tell when their child is simultaneously screaming and reeking of urine. Unless they secured a pacifier/baby gag ball to the kid's face, that is.
