It is, power window switches
Let's start with a question:
Can the glass window switch in the picture above be triggered by pressing the same as the rear sunshade button in front, opening and closing?
Ask one more question:
Nowadays, no matter how advanced the car is, many buttons can be touched, why is the window lift button always the same?
Radical like Tesla, everything is integrated into the screen or the steering wheel knob, but it still doesn't move the switch
And it doesn't matter if they're electroplated, plastic, painted and laser, etc., if you remove them, they'll always look the same:
The most important function of this design is to prevent the window from being raised inadvertently and incorrectly
Moreover, the shape design of the button must be adopted together with the pit shape, and the highest point of the button must not be higher than the surface of the sinkhole, and the size of the sinker is strictly limited at the same time
Such a design, including the size of the opening of the pit,It's all for protection, except that your fingers can be inserted into the opening of the pit, and only the upward movement can raise the window.In addition, no matter which direction the body parts are moving, such as elbows, palms, cuffs of clothing, straps, etc., there is nothing common in the car that can cause the upward movement of this button to be triggered incorrectly.
Except for fingers, any other false triggers can only lead to the occurrence of window lowering behavior, and the maximum probability is to limit the occurrence of false window raising.
(Tips: We all know that the driver's side has the highest control of 4 windows, which is why some joint venture cars such as Cadillac will give you the "rear window one-key window lowering" function, but limiting the ability of the rear "one-key window lifting", of course, due to domestic pressure, thinking that this is a reduction, after the mid-term facelift, it seems to give, add a program thing... ）
Because these designs are all bought by countries at the cost of blood
Back then, when I first popularized this content, many people told me that the windows have an anti-pinch function, "theoretically correct", but many cars do not, and even if there is, the bevel angle of the rear window is like scissors, and it can easily cause fatal damage to the trachea of young children without much force, not to mention that the sensitivity of all sensors has declined over time......
Nowadays, I believe that you can trust us experts who combine "theory" with practice
A truly good design is like a zipper, even if the product has undergone several generations of technological changes, it is still easy to use and irreplaceable.
There are many contradictory points of requirements and safety in car design, and this is when the designer plays a key role
I hope you all remember the design of this window lift button, even though we don't know who inventor this design is, but we still thank him for his wisdom.
