Hinged Wiper Connection Structure for Tight, Protected Assembly

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

VSEngineering 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 assembly tightness deteriorates causing safety hazards

Engineering Contradiction:

Improveease of assembly and disassemblyVSAvoidassembly tightness

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The wiper head is inserted into a containing chamber formed in the connection body, creating a nested structure where the wiper head is housed within the connection body. The upper cover then encloses the containing chamber, forming multiple nested layers that secure the connection while maintaining easy attachment and detachment capabilities.

Inventive Principle:

Principle #7Nested doll (Nesting)

Solution Approach 2:

The upper cover is hinged to the upper opening, allowing it to rotate between an open position for assembly/disassembly and a closed position for secure enclosure. This dynamic mechanism enables the structure to transition between accessible and tightly secured states without requiring complex fastening operations.

Inventive Principle:

Principle #15Dynamics

2Ease of operation

If a detachable connection structure is used between wiper and wiper blade, then ease of assembly and disassembly is improved, but protection against dirt deteriorates

Engineering Contradiction:

Improveease of assembly and disassemblyVSAvoidexposure to dirt

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The wiper head is inserted into a containing chamber formed in the connection body, creating a nested structure where the wiper head is housed within the connection body. The upper cover then encloses the containing chamber, forming multiple nested layers that secure the connection while maintaining easy attachment and detachment capabilities.

Inventive Principle:

Principle #7Nested doll (Nesting)

Solution Approach 2:

The upper cover acts as a flexible enclosure that can be opened for assembly/disassembly and closed for protection. This shell structure provides a barrier against dirt and contaminants while allowing easy access when needed, balancing protection requirements with operational ease.

Inventive Principle:

Principle #30Flexible shells and thin films

3Device complexity

If the wiper and wiper blade are exposed without proper covering, then assembly simplicity is improved, but susceptibility to damage deteriorates

Engineering Contradiction:

Improveassembly simplicityVSAvoidsusceptibility to damage

Core Design Contradiction:

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.
