Hinged Wiper Connection Structure for Tight, Dirt-Protected Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing windshield wiper connection structures are not tight enough, leading to safety hazards and exposure to dirt, which can damage the wiper and wiper blade.
Innovation Solution
A wiper connection structure featuring a connection body with a containing chamber and an upper cover that provides high assembly tightness and protection, with limiting parts to prevent the wiper head from falling off.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a detachable connection structure is used between wiper and wiper blade, then ease of assembly and disassembly is improved, but connection tightness deteriorates causing safety hazards
Solution Approach 1:
The connection structure is divided into a connection body and a separate cover component. The connection body contains the mounting mechanism while the cover provides protective enclosure. This segmentation allows the wiper to be easily attached and detached while maintaining secure connection through the structured interface between components.
Solution Approach 2:
The wiper blade is inserted into and nested within the connection body's containing chamber. The cover then encloses this nested structure, creating a hierarchical arrangement where the wiper is contained within the connection body which is itself protected by the cover. This nesting provides both secure attachment and protection.
2Ease of operation
If the connection structure is exposed for easy access, then ease of operation is improved, but protection from dirt deteriorates
Solution Approach 1:
The cover provides localized protection specifically for the connection interface area where dirt accumulation would be most harmful. The rest of the wiper blade remains exposed for its cleaning function. This selective coverage protects critical components while maintaining operational functionality.
Solution Approach 2:
The cover adds a third dimensional layer of protection by enclosing the connection structure vertically, rather than trying to protect it through horizontal shielding. This vertical enclosure creates a protective chamber that shields the connection interface from directional dirt and debris while allowing lateral access.
3Object-affected harmful factors
If a covered connection structure is used, then protection from dirt is improved, but device complexity deteriorates
Solution Approach 1:
The cover is integrated with the connection body through hinge connection, merging two protective functions into a single assembled unit. The hinge mechanism allows the cover to be permanently attached yet movable, combining structural support and protection in one component system rather than separate elements.
Solution Approach 2:
The cover is designed as a separate extractable component that can be removed from the connection body when needed for wiper installation or maintenance. This extraction capability simplifies the assembly process by allowing components to be added or removed independently rather than requiring complete disassembly of a complex integrated structure.

AI summary
A wiper connection structure, comprising a connection body and an upper cover. The connection body is mounted on a wiper blade; an accommodating cavity is formed on the connection body; the accommodating cavity is opened on an upper surface and a side vertical surface of the connection body respectively to correspondingly form an upper opening and an inlet for the head of a wiper to insert into the accommodating cavity; the upper cover is hingedly connected to the upper opening, and the upper cover can sealably close and open the upper opening; in addition, at least one of the accommodating cavity and the upper cover is provided with a limiting member capable of stopping and limiting the head of the wiper, so as to ensure that the head of the wiper does not fall off from the accommodating cavity.
