Differences Between Traditional Wiper Blades and Beam Blades

[LaMariana]

Traditional wiper blades operate by pressing the rubber blade against the windshield through multiple support points on a metal frame, ensuring even pressure distribution across these points. Beam blades, on the other hand, utilize a single tension band to evenly distribute pressure along the entire length of the blade, minimizing water streaks and scratches for superior wiping performance. The key differences between traditional and beam wiper blades are as follows: 1. Force Transmission Sequence: a) Traditional blades: Main arm → Primary pressure bar → Secondary pressure bar → Clamping bar → Blade. b) Beam blades: End clip → Bracket → Tension band → Blade. 2. Pressure Distribution Mechanism: a) Traditional blades feature multiple discrete pressure points. b) Beam blades employ a unified steel structure with more uniform pressure distribution. 3. Replacement Requirements: a) When replacing beam blades, the wiper arm remains unchanged. b) Traditional blade replacement requires changing both the blade and wiper arm assembly.

Oh, I've encountered this issue quite a few times. The traditional wiper blades refer to the older style with metal frames, which use a conventional skeleton support structure. They have several drawbacks, such as uneven pressure distribution, tendency for the middle of the wiper blade to lift off the windshield, leaving water streaks or making squeaky noises during operation, and being prone to freezing and getting stuck in winter. The frameless wiper blades are the newer type, featuring a single rubber blade that directly adheres to the windshield with even pressure distribution, providing a clean and ultra-quiet wiping performance—raindrops disappear with just a swipe. The main differences lie in the adhesion and noise control: the design of frameless wiper blades ensures they remain stable at any speed, unlike the older style that tends to lift at high speeds. I've also noticed that frameless wiper blades last longer, even though they're more expensive initially, saving the hassle of frequent replacements. For daily use, it's recommended to regularly check the wear condition of the wiper blades—don't wait until visibility is compromised during rain to take action; safety comes first. Overall, frameless wiper blades are more modern and better suited for new drivers or those who prioritize comfort.
