Rocker-Type Wiper Assembly Device Anti-Detachment Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wiper assembly devices tend to detach easily due to transverse mobility of the swing arm, leading to accidental disengagement and detachment during use.
Innovation Solution
A rocker-type assembly device featuring a wiper fastening base with a shaft and buckling portion, a connection base with a shaft groove for rocker-like movement, and a control member with a buckling body that engages and disengages with the buckling portion, utilizing restraining slots to limit the swing arm's movement and prevent detachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the swing arm is made transversely movable for normal operation, then the wiper can function properly, but the swing arm becomes prone to accidental detachment when the positioning member breaks or malfunctions
Solution Approach 1:
The connection base is designed to swing in a rocker-like manner about the shaft as a pivot, transforming the static connection into a dynamic one that requires active movement for assembly and disassembly. This dynamic mechanism ensures the wiper remains securely fastened during normal operation while allowing controlled detachment when needed.
Solution Approach 2:
The control member changes the positional parameter of the buckling body relative to the buckling portion through rocker-like swinging movement. By changing the position parameter from engaged to disengaged state, the system achieves secure fastening during operation and controlled detachment when the control member is actuated.
2Ease of manufacture
If a simple longitudinal assembly and transverse positioning mechanism is used, then the assembly process is simple, but the wiper tends to become detached during use
Solution Approach 1:
The connection base swings in a rocker-like manner about the shaft as a pivot relative to the wiper fastening base. This dynamic rocking mechanism provides inherent stability during operation while allowing controlled assembly and disassembly, resolving the contradiction between simple assembly and reliable connection.
Solution Approach 2:
The control member and connection base are combined as an integrated assembly that moves together in rocker-like motion. This merging of components ensures that the control member effectively drives the buckling body to engage or disengage from the buckling portion, providing both simple operation and reliable connection.
3Reliability
If the control member is moved with respect to the connection base to block the swing arm in another direction, then accidental detachment is prevented, but the device complexity increases
Solution Approach 1:
The control member is integrated with the connection base and swings together with it in a rocker-like manner. This dynamic integration allows the control member to effectively block the swing arm in the direction opposite to the first direction, preventing accidental detachment while maintaining relatively simple device structure through the unified rocking motion.
