Wiper Blade Connector With Pivot Base for Smoother Load Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wiper systems face issues with load transmission between the wiper arm and wiper due to elastically deformable snap-fitting means, leading to movement bumps and requiring multiple adapters for different wiper arm types, complicating user installation and maintenance.
Innovation Solution
A connection device with a pivotably mounted connection module featuring load-reacting means transversely flanking the connector, offset to distribute and react transverse loads, allowing compatibility with various wiper arm types.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If elastically deformable snap-fitting means are used to enable detachable connection, then ease of wiper replacement is improved, but load transmission is worsened causing movement bumps
Solution Approach 1:
The connection device is divided into distinct functional segments: the adapter with mounting means for detachable connection, and the connection module with pivotable base and load-reacting means for stable load transmission. This segmentation allows each part to optimize its specific function without compromise.
Solution Approach 2:
The connection module acts as an intermediary element between the adapter and the wiper arm, mediating the transition from detachable connection to stable load-bearing connection. The pivotable base with load-reacting means serves as the mediator that eliminates movement bumps while maintaining replaceability.
2Adaptability or versatility
If multiple specific adapters are designed for different wiper arm types, then compatibility is improved, but device complexity is worsened
Solution Approach 1:
The connection module is designed as a universal component that can interface with multiple types of wiper arms through its pivotable base and load-reacting means. The standardized connector allows a single connection module design to serve multiple adapter types, eliminating the need for numerous specialized adapters.
