Hybrid Windshield Wiper Blade Segmentation Dynamics
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing windshield wiper blades face challenges in providing consistent wiping performance across various wiper arm types due to differences in arm design and curvature of windshields, leading to inadequate contact and pressure distribution.
Innovation Solution
A windshield wiper blade design featuring a primary part with an elongated main body and secondary parts hingedly connected to accommodate changing windshield curvatures, incorporating a wiping element support track, elastic elements, and an adapter system for secure attachment to wiper arms, ensuring consistent pressure distribution and adaptability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional single-piece wiper blade design is used, then the structure is simple and easy to manufacture, but the wiping performance is inconsistent across different wiper arm types and windshield curvatures
Solution Approach 1:
The wiper blade is divided into a primary part and multiple secondary parts that can independently pivot relative to each other. Each secondary part can adjust its angle to accommodate different windshield curvatures and pressure distributions, allowing the blade to maintain consistent wiping performance across various wiper arm types and windshield shapes.
2Adaptability or versatility
If rigid connection between blade parts is used, then structural strength is maintained, but adaptability to changing windshield curvature is reduced
Solution Approach 1:
The connection between primary and secondary parts uses pivot joints that allow dynamic adjustment of angles. This enables the blade to adapt its shape in real-time based on applied pressure and windshield curvature, while the pivot joints maintain sufficient structural strength to transmit wiping forces effectively.
3Stress or pressure
If pressure is concentrated at specific points, then wiping force is strong at those points, but overall pressure distribution becomes uneven
Solution Approach 1:
Each secondary part can independently pivot to optimize local pressure distribution. The elastic elements provide localized compliance that allows pressure to be distributed more evenly across the entire blade length, ensuring all portions of the blade maintain effective contact with the windshield for consistent wiping efficiency.

AI summary
A windshield wiper blade including a primary part having an elongated main body and an interior space formed in the main body, and at least two secondary parts is provided. Each secondary part has a first end and a second end, the first end being received into the interior space of the main body, and the second end being exposed, wherein the secondary parts are hingedly connected to the primary part to swivel relative to the primary part to accommodate a changing curvature of a surface of a windshield based on pressure applied thereto against the windshield.
