The bomber is a nightmare for drone players.
However, it is also a nightmare for the consumer drone industry.
When the player's drone blows up, falls, and loses, he loses only one drone, but the drone industry loses not the player's drone, but may be the future of the industry.
However, the development of human civilization for thousands of years can not stop the fire; the development of consumer-grade drones has only been around for 10 years, and it is even more impossible to stop the bomber.
Everything in the world
How does the "fried machine" become a nightmare for the consumer drone industry?
Inquiries to several of China's largest drone companies, Dajiang and Yuxiang respectively said that they did not respond to the issue of the ratio of bombers, and Yao Benchao, the brand director of Zero Drone, said that they knew the rate of drone repair. , accounting for 30% of its sales.
This is not a small amount - according to the news, the domestic mobile phone repair rate is about 3%, while the quality of domestic mobile phones is relatively mixed, it is also about 6%, and the brand that is even worse is 20%. In contrast, the drone repair rate of 30% is really not low.
The high number of repairs is because the quality of the drone is not good? no.
Although the drone repair rate is not low, the manufacturer said that most of the time it is made by human factors. Zero indicates that among their 30% repair rate, more than 80% are human error, and 70% of these 80% are blown up on the first flight (see the above figure).
Although Dajiang did not respond to the bombing rate, they said that 85% of the bombing accidents they knew were artificially mishandled.
We do not rule out the possibility of vendors pushing responsibility to users. As we all know, consumer electronics are inherently prone to problems. I used to have four different brands of drones, but each drone had been bombed.
One of them was in the air of 10 meters in front of me, and fell off without any reason. Another trip in Yangshuo, in the sky above 260 meters, 80 meters, without birds, no antennas, no strange winds And suddenly fell (below).
In fact, the drone's tolerance for failure is extremely low. Electronic equipment may be overheated due to prolonged exposure. This is a solution for a mobile phone that can be solved with a fan blow, but the drone will fall directly in the air; the electronic compass will occasionally be disturbed by metal or electric waves. For mobile phones, it is only a positioning error, but the drone may directly hit the wall because of self-stabilization errors.
Whether it is a human factor or a mechanical factor; another pain point of the drone is that each accident will cause a lot of damage.
Unless the battery explodes or catches fire, it will rarely be reimbursed for the whole time; but if the drone falls from the air of ten meters, the precision pan/tilt will be destroyed; if the drone is out of control or the operation is wrong, it is likely to fly directly, the whole set. Reimbursement.
Pain in the user, hurt in the manufacturer
Consumer-grade drones are still not a cheap thing, but due to the above-mentioned pain points of drones, each bomber will also cause a lot of financial losses.
Even modern consumer-grade drones have flight records to determine who is responsible, but many players don't know much about drone technology, and it's easier to have a dispute over who is responsible.
The most famous one is the sb-dji.com stationmaster who set up this "anti-Dajiang website" (above) because of a flight accident, specifically posting a bomber accident about the DJI drone, due to the DJI The brand has brought a lot of influence, and it has even caused Dajiang to resort to litigation.
However, the stationmaster also said in an interview with the media:
"Consumer-level drone accidents look much more, calm down, all manufacturers of drone products will have various types of accidents, hardware defects, but also software, more is improper operation and product understanding, accidents The quantity is directly related to market share."
In the consumer drone sector, the technical level of Dajiang is close to the insurmountable level of the industry, but when the Phantom of Dajiang will also bomb, many players will have a kind of "even the big Xinjiang will be fried, there are That drone will not blow up. It is true that if the brand of DJI is hard, it will inevitably be affected, and other brands will be more difficult to escape.
Therefore, many large-scale drone companies have adopted a more conservative strategy when they encounter a bombing accident. According to relevant sources of Xiangxiang, 20% of the drones they returned to the factory for repair were confirmed to be caused by user manipulation, while the remaining 80% were difficult to judge who is responsible. Since the user experience is the main consideration, they would rather be promoted. To bear.
Zero degree Yao Benchao also said that some users are obviously human error, and they will insist on the phrase "I don't care, you pay for me". They must also coordinate according to individual circumstances, such as reducing or even exempting maintenance costs. They will also provide after-sales service by defaulting to “manufacturer responsibility†if they cannot determine who is responsible.
The above-mentioned bomber accidents and their after-sales problems have brought a lot of pressure on drone manufacturers. According to industry sources, when drone manufacturers sell a drone, their cost is 1.7 drones - an extra 0.7 drones, which may be the cost of repairs in the future.
Yuhai piezo materials include : hard piezo material, soft piezo material and lead free piezo material
Soft piezo material exhibits: larger piezoelectric constants, higher permittivity, larger dielectric constants, higher dielectric losses, larger electromechanical coupling factors, low mechanical quality factors, a lower coercive field, poor linearity, and is easier to depolarize. The ideal application of soft piezo materials is sensing needs. Yuhai soft pizeo materials are PZT-5, PZT-5H, PSnN-5 and PLiS-51.
Hard piezo material exhibits: smaller piezoelectric constants, lower permittivity, smaller dielectric constants, lower dielectric losses, smaller electromechanical coupling factors, high mechanical quality factors, a higher coercive field, better linearity, and is harder to depolarize. The ideal application of hard piezo materials is high power transducer needs. Yuhai hard pizeo materials are PZT-4, PZT-8, PCrN-4 and PBaS-4.
Yuhai company developped lead free piezo material BaTiO3 and apply for the Chinese Patent in 2011, to meet the needs of environmental protection in today's society.
