Rocker-Type Wiper Assembly Device Preventing Transverse Detachment
Solution Overview
Problem
Conventional wiper assembly devices tend to detach easily due to transverse movement of the swing arm, leading to accidental disengagement and detachment during use.
Innovation Solution
A rocker-type assembly device with a wiper fastening base, connection base, and control member that allows for a rocker-like swinging movement to secure and unsecure the assembly between the wiper body and swing arm, preventing accidental detachment by maintaining the wiper in a fixed position relative to a surface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a simple longitudinal assembly and transverse positioning method is used, then the assembly process is simple and quick, but the wiper tends to become detached during use
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 deliberate action to detach. The swing arm can still move transversely for assembly/disassembly but is locked in position during normal operation, resolving the contradiction between easy assembly and secure attachment.
Solution Approach 2:
The control member changes the engagement state between the buckling body and buckling portion through swinging movement. When swung to the engaged position, the buckling body engages with the buckling portion to lock the connection base, preventing accidental detachment while maintaining assembly simplicity.
2Ease of operation
If the swing arm is made transversely movable for easy assembly, then the assembly process is facilitated, but the swing arm can move transversely to detach when disengaged or loose
Solution Approach 1:
The control member acts as an intermediary between the connection base and the locking mechanism. It swings together with the connection base and drives the buckling body to engage with the buckling portion, providing a controlled transition between movable and locked states, thus preventing accidental detachment while maintaining assembly convenience.
Solution Approach 2:
The buckling body and buckling portion are designed to engage automatically when the control member is swung to the engaged position, creating a preliminary locking action that prevents the swing arm from moving transversely and detaching before any malfunction can occur.
3Manufacturing precision
If a positioning member for transverse positioning is added, then the wiper positioning is improved, but the device complexity increases and the positioning member can still break or malfunction
Solution Approach 1:
The positioning function is merged with the connection base and control member. The connection base swings in a rocker-like manner to provide both positioning and connection functions, while the control member integrates the locking mechanism into the same assembly process, eliminating the need for separate positioning members and reducing overall device complexity.
