Wiper Connector Cover Wing Surface Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wiper connectors with separate cover parts are prone to loss, leading to potential vehicle accidents when the wiper blade separates from the wiper arm, as the cover part only serves to cover the opening without secure integration.
Innovation Solution
A connector design that includes a pivotably connected cover part with a wing surface and fixing projections/grooves, which securely covers the opening and prevents foreign substances from entering, ensuring the wiper arm remains attached to the wiper blade.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the cover part is provided as a separate component, then the opening can be covered to prevent impurities and rainwater from entering, but the cover part is easily lost and the connection between wiper arm and wiper blade becomes unreliable
Solution Approach 1:
The cover part is integrated with the connector body to form a single unified component. The cover part includes a body portion that covers the opening and a support portion that extends to engage with the connector body, eliminating the need for separate fastening mechanisms and preventing loss during operation.
Solution Approach 2:
The cover part is positioned within the connector structure, with the body portion nested over the opening and the support portion extending inward to engage with internal features of the connector body, creating a nested configuration that ensures retention.
2Device complexity
If the cover part is simply designed to cover the opening, then the structure remains simple, but the wiper arm separates from the connector when the cover part is lost
Solution Approach 1:
The cover part combines the covering function and the fastening function into a single integrated component. The body portion provides coverage while the support portion provides structural engagement with the connector body, eliminating the need for separate fastening elements.
Solution Approach 2:
The cover part serves multiple functions simultaneously: it covers the opening to prevent contamination, provides structural support through its support portion, and secures the wiper arm connection through engagement with the connector body, replacing the need for multiple separate components.

AI summary
A connector for connecting a wiper arm to a wiper blade may be provided. The connector according to an embodiment of the present invention includes: an adaptor which includes an opening and to which the wiper arm is fastened; and a cover part which covers at least a portion of the opening and is pivotably connected to an end of the adaptor. The cover part includes: a top surface is formed in a longitudinal direction of the connector; and a wing surface which extends downward from the top surface. Accordingly, the cover part can be prevented from being separated and can be prevented from being pushed outward in a width direction of the connector, so that a U-hook of the wiper arm is prevented from being separated and the wiper arm is connected to the wiper blade with a sense of unity.
