Wiper Blade Closure Element Integrates Spring Rail
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wiper blade devices face challenges in securely and easily installing spring rails, often requiring complex connection components and resulting in a bulky design that is not lightweight or cost-effective.
Innovation Solution
A wiper blade device with a receiving unit featuring a spring rail receiving area that includes a first movably mounted closure element, which is designed in one piece with the base element, allowing for easy and secure installation of the spring rail, and optionally integrating a wind deflector element for enhanced stability and reduced weight, using a two-component extrusion process to combine different materials.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If complex connection components are used to securely install the spring rail, then the reliability of installation is improved, but the device complexity and weight increase
Solution Approach 1:
The closure element is integrated directly into the receiving unit as a single component, eliminating the need for separate connection components. The receiving unit features a receiving area for the spring rail and a closure element that forms an integral part of the same component, thereby simplifying the overall structure while maintaining secure installation through the closure mechanism.
2Stability of the object's composition
If traditional wiper blade device design is used, then structural stability is maintained, but the weight and compactness are compromised
Solution Approach 1:
The receiving unit is designed as a separate modular component that can be independently manufactured and assembled. This segmentation allows for optimization of each component's weight and structure while maintaining overall structural stability through the integrated closure element that secures the spring rail in place.
3Ease of manufacture
If the closure element is integrated in one piece with the base element, then manufacturing cost and complexity are reduced, but the ease of assembly may be compromised
Solution Approach 1:
The closure element is designed with movable characteristics that allow it to transition between open and closed positions. This dynamic design enables the closure element to be integrated in one piece with the base element for cost-effective manufacturing, while still providing easy assembly through its ability to move into the closed position to secure the spring rail.

Implementation Method 1
a spring-elastic rail which has at least one extension, in a normal operating state, in particular a longitudinal extent, that is elastically changeable, and which in particular generates a counterforce which is dependent on a change in the extension and which counteracts the change

AI summary
The invention is based on a wiper blade device with a receiving unit (10a-10d) which has a spring-rail-receiving region (12a-12d) for receiving a spring rail (14a-14d). It is proposed that the receiving unit (10a-10d) has at least one first movably mounted closure element (16a-16d) which is provided for closing the spring-rail-receiving region (12a-12d) in at least one direction (18a-18d) when the spring rail (14a-14d) is installed.
