I choose car. At the beginning of the 19th century, the French ‌ Trivico tried to use high pressure steam engine to drive a car, which can be seen as the prototype of the car. Then, in the mid-19th century, the German ‌ Otto invented ‌ gas engine, which laid the foundation for the development of automobiles. In 1885, ‌ Carl Benz built the world's first ‌ three-wheeled automobile, using a gasoline internal combustion engine. The following year, four-wheel cars began to be officially sold, marking the birth of the modern automobile. Entering the 20th century, the automobile industry ushered in a period of rapid development. In 1908, ‌ Ford Model T, with its low price and reliable performance, won the love of consumers and became a milestone in the history of automobiles. In order to improve production efficiency, Ford also invented the ‌ automobile assembly line, which greatly promoted the development of the automobile industry. At the same time, ‌ the Michelin brothers invented ‌ rubber pneumatic tire, which improved the driving performance and safety of cars.

The invention of the automobile was mainly inspired by the wheel and ‌ the internal combustion engine. ‌ The basic structure of the automobile, including the wheel and the internal combustion engine, is the basis of its invention.

‌ inspiration of wheel ‌ : the inspiration of the wheel design of the car comes from the ancient wheel car, this design makes the car can run on all kinds of roads, improve the transportation efficiency.

‌ Inspiration of the internal combustion engine ‌ : The invention and application of the internal combustion engine is the key to the development of automobiles. The early steam engine and later the internal combustion engine provided a source of power for cars, allowing them to drive autonomously

The engine generates power, which is passed through the drivetrain to the drive wheels, which ultimately propel the car forward.

engine ‌ : The engine is the power source of the automobile. It burns fuel to produce heat energy, which is then converted into mechanical energy. The working principle of the engine is mainly divided into four strokes: intake stroke, compression stroke, work stroke and exhaust stroke. This four-stroke cycle ensures that the engine is able to provide continuous power.

‌ driveline ‌ : The driveline is responsible for transferring the power generated by the engine to the drive wheels. The transmission system includes the clutch, transmission, drive shaft, main reducer and differential. The clutch connects the engine to the transmission, which adjusts the gear ratio as needed, and the drive shaft transfers power to the differential, which redistributes it to the wheels on both sides.

‌ chassis ‌ : The chassis supports and mounts the various components of the vehicle, including the drive train, travel train, steering train, and brake train. The drive train transmits power, the travel train supports the body and provides movement, the steering system controls the direction of the car, and the brake system ensures the safe stopping of the car.

‌ body ‌ : The body provides space for the driver and passengers, but also plays a protective role. Modern car body design focuses on aerodynamics to improve fuel efficiency and driving comfort.

‌ Electrical equipment ‌ : Electrical equipment includes power supplies (such as batteries and generators) and electrical equipment (such as starting systems, lighting systems, and ignition systems), which together ensure the proper functioning of the vehicle's electrical system.

Speaker is a kind of equipment that can play a piece of sound according to the electronic signal which send by the Simulated audio source or the digital source. The different signal form different quantity of input current to the speaker, and conduct to the carbon particles on the metal slice of the speaker. As the result, the carbon particles and metal slice vibrate in different frequency and amplitude, and send out the sound in different frequency, which is the timbre and pitch, and different loudness.

Speaker was first invented by Johann Philipp Reis ( 7 January 1834 – 14 January 1874) ， who was a self-taught German scientist and inventor. In 1861, he constructed the first make-and-break telephone, today called the Reis telephone. It was the first device to transmit a voice via electronic signals and for that the first modern telephone. Inspired by his physics lessons, he attacked the problem, in order to make his previous research about "the electricity could be propagated through space, as light can, without the aid of a material conductor", which he had proved by experiments and sent the result to Professor Poggendorff to insert the result to the well-known periodical, Annalen der Physik, but he had been laught at because of his unknown degree, could attract more attention from the public.

However, although the Reis telephone(speaker) is a prototye, but it did truely affact Bill to invent the improved version of the telephone, and develope to the one of the greatest invention in the modern period, and also the speaker has developed to a better quality of sound.

Dynamic Island is a new interactive UI design introduced by Apple on the iPhone 14 Pro series. It uses a combination of software and hardware to transform the hole area at the top of the phone into an interactive area that can change size and shape.

The idea and development of Dynamic Island was brought by Apple.

In an interview, Craig Federighi mentioned that Dynamic Island could be the first major operational change since the iPhone X came out five years ago. He highlighted how the new feature changed the look of the iPhone, among other things. Alan Dye noted that Dynamic Island further blurs the line between where hardware ends and software begins on the iPhone, calling it an example of "Apple-like development."

The inspiration for Dynamic Island comes from the constant exploration and improvement of the user experience within Apple. Dye mentioned that because the TrueDepth camera system is small, the team thought about what could be done with the extra space on top of the display. Their goal is to make users forget that static physical hardware exists, and make users think that the entire Smart Island is dynamic software like a fluid. This design allows users to receive notifications of incoming calls, text messages, etc., more intuitively, and to perform more complex operations in this area, such as switching songs, when using certain apps, such as music playback.

In addition, Craig Federighi also noted that at the iPhone 14 Pro event at the Steve Jobs Theater at Apple Park, people showed palpable surprise when the Dynamic Island was first revealed, and he said he had a similar reaction when he first saw it inside. He said the design gave the iPhone a new strong personality and vitality.

The invention I chose is the projector.

The Han Chinese Philosopher Mozi and the Greek Philosopher Euclid first described the phenomenon of light passing through a small aperture and projecting an upside-down image on the other side, which was known as the Camera Obscura.

The first projector was made by Edison and debut in 1890. This projector could project images up to 8 inches wide. Nine years later, William Kennedy Dickson introduced the first cinema projector. His projector has been used to display films at theatre and vaudeville shows. In 1928, RCA (Radio Corporation of America) bought Dickson’s Patent and created the RCA Photophone Corporation.

Up to now, projector has been used in a lot of different places. For example you can see a projector in school, theater, cinema or even for watching movie at home.

The inspiration for the invention of bicycles can be traced back to the end of the 18th century. In 1790, the Frenchman Comte de Sivrac had the idea of improving transportation after an unpleasant experience of being splashed in mud by a waggon. He designed and manufactured a simple wooden device with two wheels, called the "Tron horse wheel". Although this device has no transmission and steering device, and can only rely on the rider's pedalling, its appearance marked the birth of the bicycle.

In 1817, Karl Drais, a German baron, invented a two-wheeled bicycle called draisienne, a wooden frame bicycle with a steering device but also without pedals. The invention of Deles allowed cyclists to slide by pushing their feet, which aroused great interest at the time and quickly became popular on the streets of Paris.

In the following decades, the design of the bicycle has undergone many major improvements. In 1839, Scottish blacksmith Kirkpatrick Macmillan invented a bicycle with a foot pedal and crank connecting rod structure, allowing cyclists to take their feet off the ground and drive the rear wheels forward through the pedals. This improvement has greatly improved the speed and efficiency of bicycles.

In 1867, Pierre Michaux and Ernest Michaux of France further improved the design of the bicycle. They installed a rotating pedal on the front wheel, which was exhibited at the Paris Fair and caused a sensation.

In 1885, British engineer John Kemp Starley designed a bicycle called Rover Safety Cycle. This bicycle adopts a chain transmission system, with the same size of the front and rear wheels and a diamond-shaped frame, which greatly improves the safety of riding. Sex and comfort. Staley's design basically laid the foundation for modern bicycles.

In 1888, Irish veterinarian John Boyd Dunlop invented pneumatic tires, which greatly improved the riding performance of bicycles, reduced vibration, increased speed, and laid the foundation for the popularisation and development of bicycles.

The inventor of the earliest air fryer was a man named William L. Maxson who came up with a device to reheat frozen food for American troops who were deployed.

There was a lot of trial-and-error but he soon realized that if he could use extreme heat with some kind of motor that helps pass that heated air all around the food, then it would be something that could change the world.

However, the basic idea of air frying has existed for over 100 years, as can be seen in an article Technical World Magazine published in 1904. "An electric air-pressure cooker, which retains the most valuable food flavors and greatly lessens the shrinkage of meats in cooking, has been recently perfected," the article explained.

From there, the invention seemed to disappear until a William L. Maxson filed a patent for an electric oven in 1945, per Google Patents. Maxson was apparently one of those stereotypical inventors. New Air described how after growing an excessive amount of cauliflower in the '30s, Maxson decided to freeze some and cook it later. He was astounded that it still tasted fresh after reheating. According to New Air, this discovery excited him so much that he gave up on eating fresh food.

Maxson's obsession with frozen food led him to the airline industry. At the time, transatlantic flights relied on pre-made sandwiches because they kept better than a pre-made steak. Maxson figured that if you froze pre-made meals, you could have nicer food and a greater variety. So, he invented the Maxson Whirlwind Oven, which evenly circulated air that was heated by a motor. Unfortunately, Maxson died in 1947 and in the '60s, microwaves became the tool to reheat frozen food.

First of all, air fryers don't actually fry. Instead, the food goes into a perforated basket and the machine cooks the food by blowing hot air around it. The force of the air produces a convection effect that cooks and browns the exterior of the food in the basket. As long as the temperature of the air reaches more than around 320 F, breaded foods like frozen chicken tenders or unbreaded starchy items like french fries or tater tots, will in fact turn brown.

Introduction:

The air fryer has become a well-received kitchen appliance worldwide. The presence of the air fryer met the needs of people who want to cook without too much fat. Additionally, it provides an approachable way of food preparation for the people who can’t cook.

Inventor&Inspiration:

The air fryer was first invented in 2005 by David H. Mciadden in Turbochef Technologies and patented in 2006. But the application experience of this technology in the kitchen at home wasn’t expected. Then a Dutch engineer, Fred van der Weij, optimized it reson for the dissatisfaction of the low-fat fryer he bought on TV shopping. After that, he found Philips, a company which was trying to develop a cooking appliance that can make the frying process healthier, and authorized the invention to Philips. Eventually, in 2010, Philips launched out the air fryer at the IFA (International Consumer Electronics Show) in Berlin, Germany.

Principle:

The main principle of the air fryer published by Philips is the RUSH (Radiant and UpStream Heating) technology, also known as Rapid Air Technology. Inside the air fryer, the heating element above the food generates radiant heat, and the fan above the heating element rotates to produce a strong airflow. This circulate hot air at a high speed keep passing through the food, in order to cook food thoroughly.

calculator, machine for automatically performing arithmetical operations and certain mathematical functions. Modern calculators are descendants of a digital arithmetic machine devised by Blaise Pascal in 1642. Later in the 17th century, Gottfried Wilhelm Leibniz created a more-advanced machine, and, especially in the late 19th century, inventors produced calculating machines that were smaller and smaller and less and less laborious to use. In the early decades of the 20th century, desktop adding machines and other calculating devices were developed. Some were key-driven, others required a rotating drum to enter sums punched into a keyboard, and later the drum was spun by electric mentor

contact lens

The inventor of contact lenses was Otto Wetler. Wetler is a Czech scientist who invented soft contact lenses in 1963.

In the early 16th century, Leonardo da Vinci proposed the idea of wearing lenses in the eyes.In 1887, the German made the first pair of contact lenses.In 1963, Otto Wetler invented contact lenses made of soft materials.

Contact lenses are placed on the surface of the cornea, tightly attached to the cornea, and filled with tears. It forms a unified refractive system with the eye's refractive system, allowing external light entering the eye to pass through the contact lens, tear layer, cornea, anterior chamber, lens, and vitreous body in sequence, and ultimately converge into a focal point at the macular center of the retina. The tear layer formed between contact lenses and the cornea functions as a tear lens, with different refractive powers of the anterior and posterior surfaces, resulting in different refractive powers of the tear lens. When the curvature of contact lenses is smaller than that of the cornea, there is a concave lens effect; On the contrary, there is a convex lens effect.‌

In 1945, Spencer discovered during experiments that the magnetron on the radar device melted chocolate in his pocket. This unexpected discovery led him to study the thermal effects of microwaves and ultimately invented the microwave oven.

The working principle of a microwave oven is based on electromagnetic wave heating. There is a microwave generator inside the microwave oven, usually a magnetron, which generates high-frequency electromagnetic waves. These microwaves are sent into the cooking chamber of the microwave oven through a waveguide system. There is a rotatable stirrer inside the cooking chamber, usually a fan shaped metal, used to reflect microwaves and ensure that microwave energy is evenly distributed inside the cooking chamber.

The specific process of microwave heating: When microwave radiation enters food, water molecules in the food begin to vibrate and rub, generating heat. Due to the fact that microwaves can penetrate the interior of food, all parts of the food can be heated simultaneously. This heating method allows food to be quickly and evenly heated.

In 1971, Intel（a success company in microchips and semi conductors，started in 1968） company invent the first CPU, but because of technology issues, its very slow.

Charles Babbage, a Briton who designed the difference engine and the Analytical Engine, was so advanced in his design that the concept of using cards to input programs and data was adopted in the invention of the CPU. 1834: He envisioned building a machine to store programs and data in memory (punched cards). In 1840, the number of operating digits was increased to 40, and the conceptual theory of the control center (CPU). this has inspired Intel to invent the first CPU.

Instruction fetch: The CPU fetches instructions from memory, usually using a program counter (PC) to determine the location of the next instruction.

Instruction decoding: The CPU decodes the obtained instruction to determine its specific meaning and operation type. Instruction execution: According to the decoding result, the CPU performs the corresponding operation, which may involve arithmetic operations, logical operations, data transmission, etc

Temperature sensors invent in 1821, by many people, it can’t be accurate by a person

Temperature sensors work by utilizing different principles. For example, thermocouples work based on the Seebeck effect, where a voltage is generated due to a temperature difference between two junctions of different metals. Resistance temperature detectors (RTDs) rely on the change in electrical resistance of a material with temperature. Thermistors have a highly nonlinear resistance-temperature relationship.

The reasons for inventing temperature sensors are manifold. In industrial settings, they are crucial for monitoring and controlling processes to ensure quality and safety. In scientific research, accurate temperature measurement is essential for experiments and data collection. In daily life, temperature sensors are used in thermostats to maintain comfortable indoor temperatures and in appliances like ovens and refrigerators to control their operations. They also play a vital role in weather forecasting and environmental monitoring to understand and predict changes in the atmosphere and climate.

On July 24, 1874 a Canadian patent was filed by a Toronto medical electrician named Henry Woodward and a colleague Mathew Evans. They built their lamps with different sizes and shapes of carbon rods held between electrodes in glass cylinders filled with nitrogen. Woodward and Evans attempted to commercialize their lamp, but were unsuccessful. They eventually sold their patent to Edison in 1879.

In 1878, Thomas Edison began serious research into developing a practical incandescent lamp and on October 14, 1878, Edison filed his first patent application for "Improvement In Electric Lights". However, he continued to test several types of material for metal filaments to improve upon his original design and by Nov 4, 1879, he filed another U.S. patent for an electric lamp using a carbon filament or strip coiled and connected to platina contact wires.

Although the patent described several ways of creating the carbon filament including using "cotton and linen thread, wood splints, papers coiled in various ways," it was not until several months after the patent was granted that Edison and his team discovered that a carbonized bamboo filament could last over 1200 hours.
