Necessity is the mother of invention. This old proverb certainly rings true when it comes to the one home item I know I would develop if I were an inventor:
Since having children, I have learned how important it is that the delivery guy, visitors, the mail man, etc. don't ring the doorbell during nap time. A sign placed on the door (or even on the exterior doorbell button itself) is the best way I've found to address this, but even that is sometimes overlooked. This leads to my invention:
Why not create a doorbell chime that can be switched off and on as desired? The wiring would be simple and would allow the user to have complete control over when she can and can't be disturbed by the ringing of a doorbell. There might be issues of forgetting to turn it back on after the desired silence period, but this could be addressed with a timer, visual indicator, or something similar.
The product wouldn't just be great for new parents with napping infants. Shift workers who sleep during the day could also benefit. So, there's my pitch.
What about you? Do you have a home invention born of necessity? Tell us about it (or don't if you want to seek a patent before sharing it with the world!) in the comments below!
