Did you forget to lock your door? Close your garage? Turn off the lights? Well, two out of those three scenarios can be solved with this new feature that should be on every car key fob and garage remote control!

Background:

When an action is routine and uninteresting (e.g. locking a door, turning off a light, etc.), it’s sometimes hard to remember if you did it at all.

The issue:

Occasionally, people find themselves wondering “did I close the garage when I left the house?” or “did I remember to lock the car when I parked it on the street?”

Proposal:

The solution to some of these scenarios is straightforward: every remote control device could have a small LCD screen to indicate how long it has been since the last time it was used.

For example, for a garage door opener, the display might read “5 MIN. SINCE “CLOSE”.” Then you would know that you had pushed the “CLOSE DOOR” button on the remote 5 minutes ago (and thus, probably did in fact remember to close the garage door).

Since LCD displays are so cheap, this would only increasing manufacturing costs by a few cents per device. See Figure 1 for a car remote-entry key fob mockup.

Fig. 1: This car key fob allows the owner to remotely lock or unlock their car. It now has an additional feature: an LCD display indicating when the remote was last used. With this innovation, you will never again need to ponder whether or not you remembered to lock the car!

Upgraded Version Idea:

In order to reduce complexity, the system above only checks to see the last time a button was pushed, not whether the action actually occurred (most remotes are one-way, and do not have any way of determining, for example, whether or not the garage door did, in fact, close successfully).

Thus, a logical extension of the idea above would be to put a small receiver in the remote as well, so that the garage could send back a “yep, garage door closed successfully!” message. Then the LCD screen would be able to say “GARAGE DOOR LAST CLOSED 5 MIN. AGO” instead of the (somewhat weaker) statement “BUTTON LAST PRESSED 5 MIN. AGO.”

PROS: This seems like it could legitimately be a product, and it is unclear why it is not!

CONS: Adds a 15¢ cost to each device for the LCD display and additional plastic.

Save time AND the environment with this new gadget that encourages people to shut down their laptops more often. Finally, the product that the market has been clamoring for: the laptop remote-start key fob.

Background:

Some cars have a “remote start” feature to start a car before you actually get inside. This feature is typically used in regions with extremely cold  weather.

The issue:

Some people like to entirely turn off their laptops when traveling or over a weekend.

But then they have to wait a couple of minutes for their laptop to boot, log in, and start all their applications / open documents again.

Think of all the lost productivity!

Proposal:

Instead of losing precious time on Monday morning waiting for a shut-down-over-the-weekend laptop to boot, your laptop could have a special low-power “wake up” mode activated by a remote control. This would be exactly like a car remote-unlock key fob.

A comparison of laptops with and without this remote-start feature is shown in Figure 1.

Fig. 1: Top: this old-fashioned laptop doesn’t have a remote-start feature, so someone is going to have to wait several seconds for it to boot. Bottom: thanks to the remote control, the laptop on the bottom is ready to go by the time its owner walks up to it.

Conclusion:

The laptop remote could be a new differentiator between brands in an otherwise commoditized market. When every other laptop is the same, surely consumers will flock to buy the one with the “remote start” option!

PROS: Saves valuable employee time. Additionally, probably several watt-hours per year per laptop, since it encourages people to shut down their laptops. The amount of energy saved probably offsets up to a whole day of increased energy usage due to global population growth.

CONS: It might take longer to locate this remote control than to just turn on the laptop by walking over to it.
