Movable Abutment Element in Wiper Blade Adapter
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current windscreen wiper adapter systems do not effectively utilize the abutment element during operation, as it is primarily designed for mounting assistance and not for limiting angular displacement during windshield wiping.
Innovation Solution
The adapter features a movable abutment element connected by a hinge, allowing it to switch between a functional and non-functional position, which can be retracted inside the adapter, enabling it to move from its abutment position to a non-functional position, facilitating operation by preventing interference with the wiper arm's movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the stop element is fixed in the adapter, then it can assist mounting by limiting angular deflection, but it interferes with the wiper arm's movement during operation
Solution Approach 1:
The stop element is made movable rather than fixed, allowing it to change position dynamically. During mounting, the stop element projects outward to limit angular deflection and guide proper alignment. During operation, the stop element can be displaced inward by the wiper arm, eliminating interference while maintaining mounting benefits
Solution Approach 2:
The stop element is separated from the main adapter body through a hinge connection, creating an independent movable component. This segmentation allows the stop element to perform its mounting function independently while being disengageable during operation, resolving the conflict between mounting assistance and operational interference
2Object-generated harmful factors
If the stop element is made movable to avoid interference, then operational smoothness is improved, but the mounting assistance function may be reduced
Solution Approach 1:
The stop element's movability is designed to be state-dependent: during mounting, gravity and manual positioning keep the stop element in its outward projecting position to provide assistance; during operation, the wiper arm's movement automatically displaces the stop element inward, maintaining both functions without compromise
Solution Approach 2:
The hinge acts as an intermediary mechanism between the stop element and adapter body, enabling the stop element to transition between providing mounting assistance and being displaced during operation. This intermediary connection allows the stop element to fulfill both roles sequentially

Function Achieved in This Case
This design enhances the operational flexibility and effectiveness of the windscreen wiper adapter by allowing the abutment element to be out of the way during blade operation, improving the wiper's ability to follow windshield curvature and maintain efficient water removal.
