Inventions are a most crucial part of human life because it gives birth to development. Nowadays, human technology has gained fast speed.
Inventors constantly work on new technologies and try to find better ways of life. Many inventions have been made to provide an easy and comfortable way of human life in this technological era.
This blog will make aware you of some of the best inventions by engineering students, with the help of which human life can become more accessible and faster.
Mechanical engineers are being offered new subjects and updated and improved versions of their earlier subjects, focusing on the modern period in technology. Several developing technologies lie primarily under the purview of mechanical engineers.
In addition, modern mechanical engineers are adept at navigating virtual designs and adapting to new technology.
Some of the most critical trends for Mechanical Engineering students have been identified to learn about the most recent developments in this discipline.
Let us have a look at these inventions;
Passive solar waterfall
Sahashranshu Maurya and Somrup Chakraborty, two students from IIT Kharagpur, have developed an alternative that It might use to replace energy-guzzling air conditioners.
Their innovative cooling method, called Passive Solar Water Wall, focuses around a rectangular water tank installed into a wall — its large surface area permits maximum interaction between the air and the tank sides, allowing it to cool quickly.
The heat absorbed is continuously dissipated from the system through the use of water in everyday household activities.
Smart cane
India has the world's largest population of visually impaired persons, and many of them rely on the traditional white cane to go around. This cane, however, can only assist them in detecting impediments on the ground and at a range of half to one meter.
As a result, blind persons frequently collide with potentially dangerous overhanging branches, jutting air conditioners, signboards, and parked vehicles. Aside from causing injuries, these unintentional encounters are uncomfortable or frightening, making individuals apprehensive and substantially limiting their independence.
SmartCane was created by a group of dedicated technologists, an IIT professor, and a social entrepreneur to solve this obstacle.
The lightweight, foldable From a distance of 3 meters, this sturdy cane aids its user in diagnosing any above-the-knee impediment. Moreover, this product only costs INR 3,000 thanks to frugality and resourcefulness.
Water for plastic machine
Anurag Meena and Satyendra Meena, two former IIT-Bombay students, have teamed with Trestor (a Chandigarh-based startup) to create a 'Swachch Machine' that allows you to dispose of your plastic garbage while also providing clean drinking water! This breakthrough comes at a time when Indian towns are facing a big rubbish problem as well as a drought-like environment.
The concept is simple: for every recyclable waste item (such as used cans and bottles) that is inserted into the machine, the user will be rewarded with a digital value token (dubbed "trest") that It can exchange for 300 mL of clean drinking water. It was designed and constructed in just 95 days and can offer both room temperature and cold water.
Dirt detector
IIT-Kharagpur researchers have accomplished another feat by inventing a low-cost dirt detector that will soon allow public facilities to be kept clean and sanitary at all times.
Their technology can be used in areas where hygiene must be maintained regularly.
With the use of sensors, the smart hygiene monitor (SHM) can record the level of ammonia, sulfur dioxide, carbon monoxide carbon dioxide, volatile organic compounds, and particulate matter.
Solar power cold storage
As there is a lack of sufficient infrastructure and storage facilities, Indian farmers lose about thirty percent of their yield each year. However, farmers may now prolong the shelf life of their products and operate in a wider market thanks to a solution devised by Devendra Gupta, Prateek Singhal, and Vivek Pandey (all IIT Kharagpur alumni).
Ecofrost, their product, is a solar-powered cold-storage unit for farmers that can be used to preserve fruit that spoils quickly, such as spinach, tomatoes, or capsicum. These goods can now be kept in the refrigerator for up to 21 days!
Farmers may use their phones to adjust the temperature by selecting the commodity they want to keep. In addition, the storage facility is outfitted with chemical batteries that can maintain temperatures for up to 30 hours when there is no sun.
Intelligent streets lights
Chennai consumes 331.32 megawatts of power and spends Rs 52.08 crores on street lighting each year. However, around 30% to 40% of this is thrown away.
To combat this issue of energy waste, a group of students from IIT-Madras created an intelligent lighting system that ensures that streetlights are only turned on when there is vehicular traffic.
Due to sensors and a cloud network, the lights drop by roughly 30% when the roads become vacant. The concept has been tested in numerous locations on the IIT-Madras campus, with positive results. The system has a 15-year lifespan.
Zero Energy house
Consider a completely working home that uses no power and, in turn, stores energy for later use. It was created by a group of roughly 70 engineering and architecture students from the Indian Institute of Technology (IIT) Bombay.
Project Solarise is the brainchild of team shunya, which stands for 'Sustainable Habitat for an Urbanizing Nation by its Young Aspirants.' It is a 2,000-square-foot solar-powered villa with three well-furnished rooms and a well-lit and air-conditioned kitchen.
Solar panels on the roof provide the house's energy source, with the extra capability of routing excess energy generated on bright days to the power grid.
Just don't limit yourself. Even the appliances in this fully functional house (oven, cooker, etc.) are powered by solar energy.
Touch Responses T.B. material kit
Himanshu Seth, a former IIT Guwahati student, has developed a low-cost medical kit that not only provides T.B. medication but also teaches the patient. The plate-shaped device, dubbed Parichaya, has a touch-responsive audio and visual interface.
After being diagnosed with tuberculosis, a patient must visit a clinic roughly 50 times since they must take their prescription before an observer. Furthermore, patients must provide a 5-6 minute break between each dose to avoid unwanted effects.
Parichaya uses this five-to-six-minute window to interact with the patient, allowing them to listen to about 14 pieces of information, including why they need to take this specific prescription. In addition, each treatment session includes a new disc available at every treatment session.
Energy Efficient Fans
In the classic Indian summer, fans run nonstop, boosting electricity costs and using massive energy. Manoj Meena, Sibabrata Das, and Arindam, all IIT-Bombay alumni, have taken it upon themselves to develop a sustainable alternative, resulting in the Gorilla fan, an inventive device.
A Gorilla fan uses only 28 Watts at its fastest speed (one-third the electricity used by comparable ceiling fans!).
In addition, the fan has a 20-25 year life expectancy and operates in a wide voltage range of 110-285V.
In India, there are an estimated 246 million ceiling fans. But, according to the founders, Gorilla fans can save 2782 (GWH) units per year if they watch for 10 hours on average for 300 days.
So it should not only make ceiling fans more affordable for many Indian families, but it should also be enough to supply electricity to 200 million people.
Waste oil to biodiesel converter
Did you know that India produces the biggest amount of waste cooking oil globally, at 9.2 million tonnes per year?
And that the cooking oil we throw away every day can be transformed into biodiesel, solving 25% to 30% of India's energy shortage?
Through an environmentally friendly, efficient, and adaptable innovation, Abhishek Sharma, Harshit Agarwal, and Mohit Soni, three IIT Delhi students, have made it possible. It will allow small hotels, restaurants, and even households to convert their daily cooking oil waste into biodiesel in a matter of minutes.
The idea is a washing machine-sized appliance that converts waste cooking oil into biodiesel in an hour Biodiesel can also be made from oilseeds, algal oil, and jatropha oil. Furthermore, unlike wind or solar energy, the technology is simple and inexpensive.
i-Diya
In a single palm-sized device, it incorporates a lamp, USB port, and phone charger. After three years of research, Sachin Kumar of IIT-Bombay invented this solar energy system.
The desire for non-kerosene alternatives to electricity motivated his idea. He founded Illumind Solartek with three friends in 2015, and the company is already producing more of these devices.
It also sells like hotcakes; thanks to door-to-door sales, the first batch of 4500 units was gone in ten days. Its costs range between Rs 699 and Rs 999.
Ink
Four students from IIT-chemical Delhi's engineering labs devised a gadget that turns pollution from diesel generators into usable ink.
This idea was developed by Ishani, Prateek, Kushagra, and Arpit, and it was chosen for the Startup India scheme.
By connecting with the exhaust pipe, the device prevents polluting particles from diesel-powered generators from being released into the air. It then captures up to 70% of the soot from the smoke. Finally, it generates ink with this soot.
Breathalyzer Helmet
IIT Bhubaneshwar's Babely, Naman Singhal, and Shubham Jaiswal developed a helmet to catch three birds with one stone.
It is first necessary to put on the helmet and fasten the clasp. Otherwise, the rider would be unable to start the bike. After that, it checks for alcohol in the breath and, depending on the alcohol level, either starts or stops the bike.
Finally, the helmet contains a BlueTooth encryption system that can notify the owner if the bike is stolen. All of this is inexpensive and simple to incorporate into the bike. However, it's still a model that was created as a prototype in 2015.
True HB Hemometer
Ambar Srivastava of IIT-Delhi designed this cheap hemoglobin checker, a smartphone's size, and can save up to 1000 readings.
It was developed in 2014, and the All India Institute of Medical Science (AIIMS) has approved it as an effective technology that reads blood samples from a strip of paper and provides results in 45 seconds.
A CBC counter now costs healthcare facilities between Rs 1 lakh and Rs 2 lakhs, whereas our instrument costs only Rs 25,000. It also features rechargeable batteries that last for 300 tests after being charged and do not require a constant power supply.
Netra
In 2013, five IIT-Bombay students (Ankit Mehta, Ashish Bhat, Rahul Singh, Vipul Joshi, and Amardeep Singh) founded the startup ideaForge, which developed the Netra Unmanned Aerial Vehicle (UAV).
The drone was developed in partnership with the Defence Research and Development Organization (DRDO) and was first used to locate missing individuals during the Uttarakhand floods.
It resembles a giant spider, weighing 1.5 kilograms or less, with a high-resolution zoom lens that functions at all times of the day and night. It has a four-kilometer range and a 40-minute run time before requiring recharging.
E-Scooter
Swapnil Jain and Tarun Mehta invented the S340 E scooter, which operates on "other energy" and was born in the IIT-Madras incubation cell.
After three years of research and development, the duo's startup, Ather Technologies, unveiled it in February 2016. Thanks to its Li-ion battery, it can recharge faster than your phone in less than an hour. The scooter, which can reach speeds of up to 72 km/h, is made in Bengaluru.
It also boasts a touchscreen dashboard with scooter profiles, riding modes, theft protection, and navigation options. According to the developers, it will cost less than Rs 1 lakh and only be offered online.
Safer Pendant
A necklace pendant that can inform loved ones when you're in danger by tapping the pendant twice. This invention is distinguished by Delhi-based firm Leaf's Paras Batra, Manik Mehta, Ayush Banka, Avinash Bansal, and Chiraag.
The necklace is connected to the wearer's phone via an app, which will notify the designated guardians and provide a real-time map of her location.
The software and pendant were introduced through crowdsourcing in 2015, just in time for the Raksha Bandhan celebration.
Smart Earphones
Developed by IIT-Rourkee students Parth Gaggar and Vijay Jain, these earphones filter out all background noise, providing a clear, distraction-free listening experience.
Furthermore, it works with a smartphone app to choose the sounds you wish to hear and change the level.
Deaf people, on the other hand, can benefit significantly from it since they can utilize it to channel what they want to hear. For this wearable technology, Gaggar and Jain won the Ericsson Innovation Awards in 2015.
Driverless bicycle
Thirteen students from IIT-Kharagpur from several disciplines collaborated to solve a single problem: disability transportation.
They converted an ordinary bicycle into a hybrid autonomous bicycle for those with physical limitations such as blindness or severed limbs that run partially on electricity.
It took a year to design and develop the bike. Live tracking and wireless networking are among their advantages. In addition, it costs less than Rs 30,000, as opposed to Rs 40,000 and over for regular e-bikes.
Foss Laptop
A laptop for Rs 6000 with preloaded software that allows you to watch movies, listen to music, and work on documents?
It's difficult to believe, but it's true.
The goal of this IIT-Bombay innovation is to expand I.T. knowledge at a low cost. It features two USB connections, an HDMI port, an 8 G.B. nano flash drive, and 1 GB RAM, and it has a plastic casing. It is based on FOSSEE (Free Opensource Software for Education), a Linux distribution.
It's ideal for studies and low-intensity app work.
SleepDoc
SleepDoc is one of the innovations that has just earned the students of IIT Kharagpur the prestigious Accenture Innovation Challenge Grand Prize. SleepDoc is a wireless device that can assist those who have trouble sleeping.
This wireless sleep assistant can remotely monitor sleep patterns and advise required changes to the user via its clever voice-interactive technology.
A human heart and breathing rate can also be tracked using SleepDoc's live data monitoring technology. This device can also send warnings to the nearest doctor in the area if there is an alarming symptom.
Jamun seed made water purifier.
Given the world's freshwater severe constraints, all we require is a less expensive water purification option. IIT Hyderabad students appear to have found the answer, as they have devised a procedure that is inventive, low-cost, and, most crucially, long-term.
The researchers produced an activated carbon made from Jamun seeds that reduces fluoride levels in drinking water to WHO-acceptable levels.
In addition, IIT Hyderabad students have created a green alternative for recycling polystyrene and Styrofoam using orange peels. It may be the cheapest technique to clean up an oil spill on a wide scale.
Compact Bio-inspired Robot
Consider a remedy that will alleviate the pain that manual scavengers endure daily. "Unlike previous robots, propulsion in a bio-inspired robot is due to flapping of fins rather than motor movement," a representative from IIT Madras was cited as saying.
This one-of-a-kind characteristic allows the robot to survive in highly hostile situations. This robot can do it all, from removing a clog in sewage lines to diagnosing wear and tear."
This robot is capable of inspecting septic and sewage systems as well as cleaning the pipes.
