There are so many configurations that it is completely unnecessary.
In other words, it is designed for coolness, not for user needs, nor for engineering needs, nor for safety needs.
It is true that cool is also one of the needs of users, but if the appearance of this configuration reduces the user's sense of experience and produces potential safety hazards, this design must be eliminated from the perspective of rigorous engineering disciplines.
Since electrification, there are two configurations that are very unnecessary.
One is the panoramic canopy that makes everyone very miserable in summer, and the other is the hidden doorknob that everyone criticizes.
The appearance of the panoramic sunroof is purely to make the product configuration look more competitive, and the traditional iron sheet + beam structure is replaced by special glass.
Instead, there is better daylighting, but the problem is also very obvious.
Although all manufacturers are promoting glass UV protection, no problem, but the conduction of heat has always been infrared, and the ability of glass to isolate infrared rays is very weak, even if it is tinted glass, it is inevitable that there will be overheating in the car in summer.
This is a hard injury that can't be solved by turning on the air conditioner, and the most effective way is to wear a sunshade.
In addition, I have never believed that the safety of a panoramic canopy is the same as that of a normal car roof, and the roof of a traditional vehicle usually has at least three beams, and the reliability of the iron sheet after an impact is always safer than that of glass.
Whether it is post-maintenance or the convenience of daily use, the appearance of the panoramic canopy is just a "show-off", but it is a useless configuration.
The other is the problem of hidden door handles, which have been very hot recently.
The original intention of the birth of the hidden door handle is to the so-called "reduce wind resistance" and improve the battery life.
When it comes to keeping energy consumption low, that's right. But there are three problems with concealed doorknobs that can never be changed.
1. The hidden door handle has an additional motor pop-up system, and the cost will be higher.
2. As the most used configuration in daily life, it chooses more complex engineering logic, and the complexity of daily use increases.
3. There is no doubt that the uncertain factors that cannot be bounced off after the collision increase, even if it increases by 1%, it will increase the trouble for the rescue after the accident.
In view of the above three points, the hidden door handle in exchange for a negligible increase in battery life is obviously a "reverse Tiangang" approach.
Theoretically, the battery is fully charged and discharged for a full cycle, and the hidden door handle can run 1% more, but it is only in theory, and more power will be supplied to the motor, followed by air conditioning, audio, headlights, and screen systems.
Concealed door handles don't save even 1% of the electricity.
For a long time, a large number of consumers have been complaining about the impracticality and safety hazards of hidden door handles, and some companies have replaced semi-hidden door handles, but there are still some companies that still insist on using hidden door handles.
But we adhere to a principle, all configuration is for daily use, comfort, convenience, safety, more important.
