Wiper Connector with Rotatable Stopper for Secure Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wiper connectors face challenges in securely attaching the wiper arm while maintaining ease of assembly and disassembly, with some designs being overly secure and others lacking in detachment prevention.
Innovation Solution
A wiper connector featuring a connector body with a longitudinal groove and a stopper that is rotatably and detachably positioned, utilizing a pivot portion, shaft portions, snapping members, and elastic arms to securely attach and detach the wiper arm, ensuring stability and ease of operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the cover is arranged to be not easily detached or opened to securely prevent the wiper arm from being detached, then the reliability of preventing detachment is improved, but the ease of operation for users deteriorates
Solution Approach 1:
The cover transitions from a static fixed state to a dynamic state with defined movement trajectories. The guide grooves constrain the cover to move along specific paths during assembly and disassembly, enabling users to easily open and close the cover while maintaining secure retention of the wiper arm through controlled mechanical interaction
Solution Approach 2:
The guide grooves act as intermediary elements between the cover and the connector body. These grooves mediate the interaction by providing controlled movement paths that enable easy user operation while simultaneously ensuring proper positioning and secure engagement of the cover with the wiper arm assembly
2Ease of operation
If the cover is made easily detachable or openable to facilitate user operations, then the ease of operation is improved, but the reliability of preventing the wiper arm from being detached deteriorates
Solution Approach 1:
The cover is designed with dynamic characteristics that allow easy movement during assembly and disassembly through the guide grooves, while maintaining reliable retention functionality when in the closed position. The controlled mobility enabled by the grooves ensures that ease of operation does not compromise security
Solution Approach 2:
The guide grooves serve as intermediary structures that facilitate easy user operation by providing defined movement paths, while simultaneously ensuring that the cover maintains proper engagement with the wiper arm. This intermediary mechanism resolves the conflict between ease of access and secure retention by controlling the interaction between the cover and connector components
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution provides a secure retention of the wiper arm while allowing for easy detachment and assembly, enhancing user convenience and maintaining a consistent appearance.
Implementation Method 1
the guide surface abuts against the elastic arm so that the elastic arm is elastically deformed, thus enabling the abutment portion to detachably abut against sidewall of the retaining portion or the snapping portion, which is a groove

AI summary
A wiper connector and a wiper assembly thereof. The connector is detachably coupled between a wiper arm and a wiper, wherein the connector comprises a connector body and a stopper. The connector body has a longitudinal groove. One end of a stopper is detachably and rotatably disposed at one end of the longitudinal groove, and the other end of the stopper is detachably retained to the longitudinal groove so that the stopper movably shields a part of an opening of the longitudinal groove.
