Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wiper systems face challenges in providing a simple and reliable maintenance process, particularly in replacing worn wiper blades without damaging the connecting device or risking unintentional adapter release during system use.
Innovation Solution
An adapter with U-shaped front and rear parts hinged together, featuring a rotation mechanism and actuating means, allows for secure attachment to the drive arm, enabling easy assembly and preventing unintentional release, while ensuring a robust connection between the wiper blade and drive arm.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an adapter is designed to securely connect to the drive arm, then connection reliability is improved, but the complexity of the adapter structure increases
Solution Approach 1:
The adapter is divided into two separate U-shaped parts that can be assembled together, allowing each part to be simpler in structure while achieving reliable connection when combined. This segmentation enables the adapter to maintain reliability without requiring a single complex monolithic structure.
Solution Approach 2:
The adapter incorporates a pivoting mechanism that allows dynamic adjustment and secure engagement with the drive arm. The U-shaped parts can pivot relative to each other, providing adaptability to different drive arm configurations while maintaining a reliable connection through the dynamic engagement mechanism.
2Ease of operation
If the adapter allows simple and rapid maintenance operations, then ease of operation is improved, but the connection strength may be compromised
Solution Approach 1:
The separable U-shaped parts can be quickly assembled and disassembled for maintenance, enabling rapid blade replacement. The segmented design allows the adapter to be easily taken apart for maintenance operations while maintaining sufficient connection strength through the engineered engagement features of each segment.
Solution Approach 2:
The adapter is pre-configured with engagement features and pivoting capability that enable quick connection and disconnection during maintenance. The preliminary design of the U-shaped parts with complementary geometries allows users to perform maintenance operations rapidly without compromising the strength of the connection when properly assembled.
3Reliability
If the adapter prevents unintentional release during use, then reliability is improved, but the device complexity increases
Solution Approach 1:
The pivoting mechanism provides dynamic locking capability that prevents unintentional release during wiper operation. The U-shaped parts can pivot into a locked position that secures the connection, and this dynamic feature is achieved through the inherent geometry of the pivoting joint rather than additional complex locking mechanisms.
Solution Approach 2:
The adapter combines the pivoting mechanism and connection function into a single integrated structure. The U-shaped parts serve both as the connection interface and as the pivoting joint, merging multiple functions into one component to prevent release without significantly increasing overall complexity.
