"Life - race in the Rainstorm": Your Wiper is Staging a Real - life Version of Lychees of Chang'an
In the movie Lychees of Chang'an, the minor official Li Shande received the arduous task of transporting fresh lychees from Lingnan to Chang'an. Despite the difficulties of the lychees being perishable and the long journey, with wisdom and perseverance, he continuously explored and improved, and finally created a miracle and completed an impossible task.
And today, your wiper is accomplishing the same arduous mission —— keeping a clear vision for you in the rainstorm and safeguarding every journey.
Li Shande had to overcome three major challenges of time, distance, and preservation when transporting lychees. The working challenges of the wiper are equally thrilling:
Time Challenge; In a rainstorm, it needs to swipe 1 - 2 times per second to ensure the view isn't blurred by rain.
Distance Challenge; Each time the rubber strip swipes, it covers the entire windshield, equivalent to “running” dozens of kilometers every day.
Preservation Challenge; Rubber aging and oil film accumulation can make the wiper “fail”, just like the irreversibledeterioration of lychees.
Small as it is, the wiper is the "lifeline" for driving in rainy weather
Last week, during a heavy rain in Beijing, car owner Mr. Li experienced a terrifying moment. While driving at high speed, the wiper suddenly made a harsh noise and then left large water marks on the windshield, almost causing a rear - end collision. After the incident, an inspection revealed that the seemingly intact wiper rubber strip had severely aged, with tiny cracks all over its surface that were barely visible to the naked eye. And such news is not an isolated case.
Three Fatal Risks of Wiper Failure
1. Blurred Vision, Skyrocketing Accident Rates
In heavy rain, wiper failure will delay drivers' reaction time and pose a risk of driving blindly. Most rainy - day accidents are related to wiper malfunctions or improper use.
2. Return Spring Failure, Wiper "Strike"
The return spring is the "homing commander" of the wiper. Once aged or broken, the wiper may stop in the middle of the windshield, blocking the view and even causing the glass to fog up. Long - term neglect may lead to the deformation of the linkage rod and double the repair cost.
3. Inferior Rubber Strip "Scratches More and More Blurry"
Inferior rubber strips will leave water marks on the glass, causing glare at night and seriously affecting the view. When swinging at high speed, aged wipers may jump, reducing the effective view by 40%.
How Long Can Your Wiper Last?
Check: Are there cracks or gaps in the rubber strip?
Listen: Is there any abnormal noise when wiping?
Test: Are there still water marks after spraying glass water?
⚠️If any problem occurs, replace it immediately.
