Wiper Blade Adapter Latching Mechanism for Rapid Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wiper blade adapter systems lack a rapid and stable method for installing different wiper arm adapter systems, with existing solutions being cumbersome and not easily adaptable.
Innovation Solution
A wiper blade adapter device featuring a latching unit with a latching recess and element, where the latching element has a drop shape and is formed integrally with the basic adapter, allowing for a stable and rapid coupling between the basic and special adapters, and optionally welded for a secure connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a latching unit with latching element and recess is used to connect basic adapter and special adapter, then the installation speed and stability are improved, but the device complexity increases
Solution Approach 1:
The latching element is designed to automatically engage with the latching recess when the special adapter is inserted into the basic adapter, without requiring manual operation or additional actuation mechanisms. The spring-loaded latching element self-activates through the insertion motion itself, achieving rapid connection while maintaining simple structure.
Solution Approach 2:
The latching function is extracted as a separate, dedicated component (latching element) that can be independently designed and manufactured. This modular approach allows the latching mechanism to be integrated into the basic adapter without complicating the overall design, as the latching element is a simple spring-loaded pin that fits into a corresponding recess.
2Manufacturing precision
If the latching element is formed integrally with the basic adapter, then manufacturing precision and connection stability are improved, but the ease of manufacture decreases
Solution Approach 1:
The latching element is integrally formed with the basic adapter through injection molding, combining two components into one. This integral construction ensures precise alignment and stable connection between the latching element and the basic adapter, eliminating assembly errors while maintaining manufacturing efficiency through single-step production.
3Ease of operation
If the latching element has a drop shape, then the ease of operation is improved, but the manufacturing precision requirements increase
Solution Approach 1:
The latching element is designed with an asymmetric drop shape, featuring a rounded head and a tapered tail. This asymmetric geometry provides clear directional guidance during insertion, allowing the special adapter to be easily oriented and inserted into the basic adapter without complex alignment procedures, while the rounded head accommodates reasonable manufacturing tolerances.
4Strength
If welding is used to secure the connection between basic adapter and special adapter, then the connection strength is improved, but the ease of repair decreases
Solution Approach 1:
The connection system is segmented into two modes: a primary mechanical latching connection for normal operation that allows easy release and reconfiguration, and an optional secondary welding connection for permanent securing when required. This segmentation enables the system to provide both strong connection and ease of repair by simply removing the welding step.
