VEHICLE WINDSHIELD WIPER BLADE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18158617 titled 'VEHICLE WINDSHIELD WIPER BLADE
Simplified Explanation
The abstract describes a vehicle windshield wiper blade with a specific design and material properties.
- The wiper blade has a blade support portion and a lip portion.
- The lip portion has a tapered portion with a gradually decreasing width.
- The tip surface and first and second tapered surfaces make up the tapered portion.
- In a specific observation region, the elastic modulus is measured at a 0.1 μm pitch.
- The average value of the elastic modulus in this region is 15-470 MPa.
- The coefficient of variation of the elastic modulus is at most 17.6%.
Potential Applications:
- Automotive industry - windshield wiper blades for vehicles.
Problems Solved:
- Improved performance of windshield wiper blades.
- Enhanced wiping efficiency and effectiveness.
- Reduction of streaks and smears on the windshield.
Benefits:
- Better contact with the windshield surface.
- Improved durability and longevity.
- Enhanced performance in various weather conditions.
- Reduced noise and vibration during operation.
Original Abstract Submitted
A vehicle windshield wiper blade comprising: a blade support portion; and a lip portion, wherein the lip portion has a tapered portion having a cross section that is taken along a direction perpendicular to the longitudinal direction of the wiper blade and that has a width that gradually decreases from a side closer to the blade support portion towards a direction farthest away from the blade support portion, the lip portion has a tip surface and first and second tapered surfaces constituting the tapered portion, and, in a specific observation region of the first and second tapered surfaces, the average value of the elastic modulus measured at a 0.1 μm pitch is 15-470 MPa and the coefficient of variation of the elastic modulus is at most 17.6%.
