Mechanical engineering is one of the widely recognized fields of engineering. During the four-year course, every student has to submit at least one project related to the mechanical engineering field. However, most of the time, it is hard to come across ideas, especially when there is a short time left. Seeing the problem, this article will discuss the top 10 best mechanical engineering project ideas.

Notably, mechanical engineering deals with producing and developing mechanical devices like refrigerators, generators, elevators, cars, airplanes, air conditioners, and many more. In every field, from space technology to the healthcare industry, mechanical engineering has helped develop many valuable assets. Let’s dive into discussing the top 10 best mechanical engineering project ideas without wasting another second.

1. Automated Potato Peeling Machines

The first one among the top ten best mechanical engineering project ideas would be automated potato peeling machines. Potatoes are one of the most widely used vegetables on the Earth. One of the most loved fast foods, French Fries, is also made from them. Imagine how many workers would be needed just for peeling potatoes. This problem could be solved by creating an automatic potato peeling machine.

A single-phase ac motor is used to drive the peeler wheel filled with 5 kilograms of potatoes. It also contains a water tank of five liters that sends water to the potato chamber to wet them for easy peeling. The ac motor is attached to the peeler rotor through a pulley belt arrangement.

2. Hydraulic Flood Protection System

Flood-prone areas get widely affected during the monsoon season. People living in those houses have to face a lot of uneasy circumstances. However, the problem could be solved by building a hydraulic flood protection system.

It is a futuristic project based on the hydraulic lifting concept, i.e., whenever the flood strikes, houses can be hydraulically lifted to avoid the flood water entering inside the house.

Three metal rods would be buried 3 meters above and below the ground during the house construction. These rods would avoid the danger caused by strong winds and storms. Four hydraulic cylinders that uplift the house during the flood will be attached to the steel platform mounted on the four sides of the house. The hydraulics function using a high torque, and the motor are two-sided for driving fluid in and out.

3. Solar SeaWater Desalination Machine

This machine goes through three stages to desalinate seawater. In the first stage, a user has to pour saline water via an inlet. Large particles like stones, weeds, and plastic granules get separated here. The water is then sent to a purification chamber with three levels of purifiers for filtering out harmful particles.

Now, the output will be particle-free water, but it will still contain the salt-like taste, which can be removed by sending the water to the second filtration chamber, which uses the reverse osmosis process. The second filtration uses three membranes to remove the saltiness of the water. The removed salt gets collected in membrane filters.

4. Mini Solar Water Heater

Solar water heaters are known to heat cold water faster than any traditional electrical water heater. In this system, water passes through a steel pipe. When the solar energy falls on the steel pipe, it gets heated. The excess solar energy which passes between the pipes falls on a black-colored metal plate attached to the steel pipes. Two additional sheets are added to reflect and gather energy. This whole system collects enough solar energy to heat the water passing through the steel pipe.

5. Frictionless Electromagnetic Braking System

The fifth idea among the top 10 best mechanical engineering project ideas is a frictionless electromagnetic braking system. The old braking system converts kinetic energy to heat energy, which has some disadvantages. A new no-friction electromagnetic braking system has been proposed, which works on the eddy current concept. Eddy current gets generated when there is motion between a conducting metal and a magnet, producing a magnetic field. The created magnetic field decelerates the motion of the object. These kinds of electromagnetic brakes are frictionless, so there would be no worry about their maintenance.

6. Five Layer Indoor Farming Hydroponic Plant Grow Tent

Due to the increasing global warming and deforestation, it is essential to find new and sustainable ways to grow plants and produce foods from the pace of our homes. Five layers of indoor farming hydroponic plant grow tent allow people to grow 25 plants collectively.

In the absence of sunlight, the inside lights of the tent help plants carry out the process of photosynthesis. The presence of sensors helps determine the drop in water level and temperature change. The irregulated temperature can get regulated with the help of four fans. The best of this system is that it runs on solar energy for charging its batteries.

7. Wind and Solar Laptop/Mobile Charging Station

Every now and then, when the electricity goes off, or there is no way to charge your laptop or phone when you are out, then wind and solar charging can prove to be the panacea. In this system, a battery is connected to the solar or wind panel to collect the energy. This battery is connected to an inverter for usage. It gives out only two types of outputs. One output is for mobile charging, and another is for laptop charging. The attached wheel allows the station to be portable and used near bus stops, stations, parks, etc.

8. Automated Waste Segregation System

The disposal of waste and garbage has become a significant concern on the Earth. Especially in rural areas where there is no waste segregation system, it has become essential to introduce a technique that can effectively segregate waste. Automated waste segregation is one such system that segregates waste products effectively and is also easy to operate.

This system contains a pipe which, when filled with waste, the IR sensor attached to it senses the garbage based on its category it belongs like dry, wet, or metallic. When the machine feels the waste is dry, wet, or metallic, it throws it into the related dustbin.

9. Voice-Controlled Robotic Vehicle

The voice-controlled robotic vehicle is used to control robotic vehicles through voice send via the android application. The android system gives a good GUI, enabling the user to manage the robotic vehicle effectively. Inside the motorized vehicle, the connected Bluetooth devices and control unit capture and read the voice sent through the android application.

10. Firefighter Robot With A Night Vision Camera

The last one among the top 10 best mechanical engineering project ideas is the firefighter robot with a night vision camera. This system is equipped with a fire-extinguishing gun and a water tank. The robot can be used to extinguish a fire after receiving commands from the receiver circuit in the form of RF signals via the RF-based remote.

The receiver circuit decodes the sent command and then forwards that to the microcontroller installed inside the robot. After receiving the information, this microcontroller instructs the motors to go in the ordered direction. Through the firefighter robot, a user can effortlessly extinguish the fire by standing in a safe place.
