Smart Air Conditioning Technology: Home Temperature Control Experts

Smart appliances are closely related to people's lives. Smart washing machines, smart refrigerators, and smart air conditioners have become indispensable helpers in people's daily lives. In particular, smart air-conditioning, which highlights the people's demand for smart home smart overall performance enhancement, is becoming a hot competition for home appliance companies. We take the Japanese Mitsubishi and Daikin Air Conditioning as examples to make in-depth analysis of the development trend of smart air-conditioning technology.

Mitsubishi Intelligent Air Conditioning Technology Patent Solution

After the disintegration of Japan’s Mitsubishi Corp., Mitsubishi, which we now refer to, is mainly composed of Mitsubishi Electric and Mitsubishi Heavy Industries. The history of Mitsubishi Heavy Industries can be traced back to the Meiji New Year, and Mitsubishi Electric was established in 1921. Its predecessor was the Mitsubishi Shipbuilding Kobe Shipyard's "Motor Manufacturing Plant."

Air conditioning is a representative product of Mitsubishi Electric. Mitsubishi began producing air conditioners in 1954. In 1968, it successfully developed the world's first split wall mounted air conditioner.

Currently Mitsubishi Electric is already the world's leading air-conditioning compressor manufacturer. From the perspective of Mitsubishi’s annual applications in the field of smart air-conditioning, Mitsubishi was involved in the research and development of smart air-conditioning in the early 1980s. There were few patent applications from 1980 to 1985, and it was in its infancy. The number of patent applications increased significantly from 1986 to 1988, and the number of patent applications continued to increase each year. Subsequent applications began to gradually decrease, and the changes are huge. After a breakthrough in 1993, the number of applications in 1994 quickly became zero. Until 1999, Mitsubishi smart air conditioner ushered in a longer period of growth, driven by the development of the Internet of Things and the growth of the smart home market, after 2002 the number of patent applications tends to be gentle, Mitsubishi's smart air-conditioning technology is basically To mature and stable. According to Mitsubishi’s data on the U.S. patent application target country/her zone, Mitsubishi focused on the target market in the field of smart air-conditioning in Japan. The development of overseas markets did not form a scale, and mainly focused on China, Europe, and United States and other countries.

Japan Daikin smart + air conditioning technology patent solution

Daikin Industries, Ltd. was established on October 25, 1924. Yamada Akira was founded in Osaka, Japan, under the name "Osaka Metal Industry Institute." Daikin was the first manufacturer of radiators for aircraft pipelines. Since 1933, it began researching fluorine-containing refrigerants. In 1935, it successfully developed fluorocarbons. Subsequently, it began to enter many refrigeration-related industries with its leading research in refrigerants. Especially in air-conditioning and refrigeration, Daikin's product range reaches as many as 5,000. Today, Daikin has become a specialized company integrating the research, development and production of air conditioners, refrigerants and compressors.

From Daikin's application data in the field of smart air-conditioning over the years, it is involved in the field of smart air conditioning slightly later than Mitsubishi, but the development momentum is strong. From 1985 to 1988, Daikin’s patent applications in the field of smart air-conditioning increased year after year. After a sharp decline from 1989 to 1991, there was a sudden increase from 1992 to 1993, after which it began a large-scale decline until 1999. It will only usher in a period of rapid development. Looking at the trend of Daikin's patent applications, the volatility is more obvious due to multiple layers of reasons.

According to Daikin’s application for global patent applications in the field of smart air-conditioning technology, Daikin also targets the target market in Japan, but compared with Mitsubishi, Daikin’s overseas patent applications have increased significantly. , Europe, the United States, Australia and South Korea, and the layout of Daikin's PCT applications as many as 29, indicating that Daikin has begun to pay attention to the patent layout of overseas markets.

Mitsubishi and Daikin's Smart Air-Conditioning Technology Patent Comparison

From the perspective of patent application data, Mitsubishi and Daikin have been involved in the field of smart air-conditioning for a similar amount of time, and the number of applications over the years has shown wave-like development. The development trend is very similar, but from the perspective of the overall number of applications, the total number of Mitsubishi patents is greater than the total number of applications. gold.

Looking at the layout of patents, both Mitsubishi and Daikin focused their smart air-conditioning patent applications on Japan, and the overseas patent layout was far less than the domestic patent layout. However, regarding the amount of overseas patent applications, Daikin is more concerned with overseas markets. Regardless of the number of patents or the country of patent applications, Daikin is higher than Mitsubishi, which is mainly related to the difference in the development strategy of the company.
