25 Useful Inventions That Make Life Easier

The desire for convenience and efficiency is the main source of inspiration for inventors. After all, people are attracted to technologies that simplify life.

Let consider 25 brilliant innovations that meet different needs: from water purification to one-
time charging. These are vivid examples of how talented people find problems, develop solutions, and implement them for the benefit of humanity.

Smart Socket

Technical progress has also reached such a simple thing as an outlet. First, the smart device is
equipped with a timer that allows you to turn on and off your devices at the right time. When you
leave the house, you will be sure that the iron and stove are de-energized. Also, the timer helps to
save electricity.

Secondly, the socket controls the voltage in the network, and your expensive devices are not in

Smart Temperature Controller

A useful device that allows you to automate the air conditioning system in the house. The
thermostat controls the temperature of the house, transmitting data directly to the smartphone.
– Programming on your own;
– Aability to control the consumed energy;
– Remote temperature monitoring and control;
– The reduction of energy consumption.

Smart Fridge

Unlike electronic vacuum cleaners, a smart refrigerator is still exotic for wealthy geeks. But in a
couple of years, this technique will be equal to the advanced models of ordinary refrigerators,
and then it will become the standard at all.
Smart refrigerators select the optimal temperature for all compartments, taking into account the
products inside, determine the humidity level, and enable uniform cooling on the shelves. These
devices have a fault diagnosis system, and you can control smart refrigerators from your

Innovative models that will soon be on sale allow you to view the contents of the refrigerator on
your smartphone, control the expiration date of food, and even make shopping lists.

Kettle with Wi-Fi

Today, even an inexpensive kettle from popular brands can be safely connected to the network.
And not only the kettle, but also, for example, a slow cooker.
Why do your kitchen utensils need Wi-Fi? First of all, this is a real paradise for the lazy. Lie on
the couch, go to the gadget app and turn it on. Secondly, the network connection allows you to
determine the operating mode, including temperature. For example, boiling water or just
maintaining the temperature.
In some models, you can directly specify the required water temperature. For green tea, the
temperature is not very high; and for black tea, you need boiling water.

Video Peephole

Even the simplest device for a few hundred dollars has a whole set of nice features. At the same
time, it is indistinguishable from a standard peephole and will not confuse neighbors.
A color monitor will help you see in detail what is happening behind the door. It is easy to install
and works on regular batteries. More expensive models are characterized by high image clarity, a
GSM module for communication with the guest, a wider viewing angle, the ability to record
photos, IR illumination, and USB charging.

Smart Lock

In science-fiction movies, the keys to the front doors have long been replaced with fingerprints.
But not everyone understands that this is not the future, but the present.
The smart lock is installed instead of the usual one and allows you to open the door by
fingerprint – exactly as you unlock your smartphone. Besides, you can close it from the inside
with a single button. If unwanted guests enter the house, the alarm will go off, and the thieves
will remain inside.
Moreover, you will not have to make copies of keys for relatives: you can distribute them using
your smartphone. Otherwise, the gadget is not inferior in terms of security to modern locks.
What is important, you will cause surprise and admiration of your guests in the house.

Robot Vacuum Cleaner

In recent years, the robot vacuum cleaner has turned from an exotic for high-tech fans into a
familiar gadget. Vacuum cleaners are equipped with height sensors (so they won’t fall off the
stairs) and obstacle detection. Such devices themselves return to charging, penetrate hard-to-
reach places, and are able not only to vacuum the floor but also to thoroughly wash it.

Flexible Camera For a Phone

A camera similar to an endoscope appeared relatively recently on the market but has already won
a leading position. Even though this device is similar to a medical device, it still has some
differences with it. And first of all, this is the scope of application. Thus, the device allows you
to view details that are impossible to see with your eyes or impossible to reach with a regular

Automatic Feeder

Even the simplest gadget in this category can deliver food on a schedule, using several programs
and a feed dispenser. More advanced models have, for example, a camera that can transmit
photos or videos to the app. Food is issued not only by preset. You can give the command to
pour food at any time via your smartphone (even when you are at work or away).
Smart feeders are also able to reproduce messages from owners. Your pet will not be so lonely
when you are at work.

An App to Help The Visually Impaired and Blind

Technologies that simplify life can't do without Be My Eyes. This is a mobile application
through which a person with vision problems can get help from a seer. The functionality is based
on video calls: the visually impaired person contacts a volunteer, who helps them navigate
through the video.
The founder of the project also has poor eyesight. Based on his own experience, he claims that
the app will change the daily life of blind people, thanks to remote assistance.

Edible Water Packaging

This invention from the UK is made from seaweed extract and wins over plastic bottles in terms
of environmental friendliness. Ooho can be safely discarded in nature because the material is
easily decomposed and processed by the soil. Moreover, it can even be eaten without harm to
health. However, the product has no taste.
For hygienic reasons, it is produced in two layers – the outer shell is discarded before using the
inner one. Ooho developers claim that the production of such packaging is cheaper than plastic
bottles, but does not threaten the environment and does not complicate disposal. Such
technologies that simplify life will make nature better.

Hand-operated Dishwasher

Circo is a dishwasher designed by Israeli designer Chen Levin. This is a self-contained
household appliance that does not consume electricity but is operated manually. The user only
needs to rotate the handle of the device – this movement creates a jet of water, which is heated
using a sodium acetate tablet. The dishwasher saves not only time and electricity but also water.
