What is the difference between conventional and beam wiper blades?
2 Answers
The differences between conventional and beam wiper blades are: 1. Different principles: Conventional wiper blades press the wiper rubber against the glass through multiple support points on the frame; beam wiper blades apply force directly to the steel strip. 2. Different force distribution methods: Beam wiper blades distribute force across the entire rubber strip; conventional wiper blades transfer pressure through layered pressure strips. Wiper maintenance precautions include: 1. When using wipers to remove dust from the windshield on sunny days, always spray windshield washer fluid and avoid dry wiping; 2. Manually remove any stubborn or hard contaminants on the glass; 3. When lifting the wiper blade, hold it by the spine and gently place it back; 4. In winter, use an ice scraper to remove ice from the windshield surface first; 5. Repair any wiper malfunctions promptly.
Traditional wiper blades have a metal frame in the middle, divided into several sections like fish bones. My old car uses this type. It relies on several connection points to press the blade against the windshield. Over time, the middle part tends to lose pressure, especially on windshields with a large curvature, leading to incomplete wiping and water streaks. I experienced this danger during heavy rain on the highway last time—blurred vision was particularly hazardous. In contrast, frameless wiper blades have a steel strip embedded entirely in rubber, distributing pressure evenly. After switching to them on my new car, the wiping performance improved significantly. The downside is the higher cost, and they may not fit well on windshields with very flat curvature.
