Wiper Blade Connector With Offset Rotary Platform for Multi-Arm Fit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Automotive vehicles require different adapters for various types of wiper arms, leading to increased manufacturing complexity and user confusion in selecting the right adapter for wiper blade installation.
Innovation Solution
A connection module with a pivotable base and a rotary platform, where the pivot and rotation axes are parallel but longitudinally offset, allowing the rotary platform to adapt to different wiper arm types while maintaining optimal bulk and aerodynamic design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a base wide enough to retract the rotary platform is used, then the rotary platform can be retracted into the base, but the base occupies more space and increases the overall bulk of the connection device
Solution Approach 1:
The patent positions the rotation axis offset from the base center, enabling the rotary platform to rotate out of the base's longitudinal dimension. This dimensional repositioning allows the platform to achieve its retraction function without requiring the base to be wider, thus reducing the base's volume while maintaining adaptability.
2Adaptability or versatility
If a base long enough to offset the rotation pin is used, then the rotation pin can be offset, but the base occupies more space and increases the overall bulk of the connection device
Solution Approach 1:
The patent offsets the rotation axis from the base center along the longitudinal dimension, allowing the rotary platform to achieve its rotational function with a more compact base. This strategic positioning in another dimension enables the rotation pin offset capability while minimizing the base's volume.
3Reliability
If multiple different adapters are designed for different wiper arm types, then each adapter can be optimized for its specific wiper arm type, but manufacturing complexity increases and users face difficulty in selecting the correct adapter
Solution Approach 1:
The patent designs a universal connection device with a base and rotary platform that can accommodate multiple wiper arm types through a single adapter. The rotary platform's ability to rotate and the offset rotation axis enable this universal adapter to adapt to different wiper arm profiles and dimensions, eliminating the need for multiple specialized adapters and simplifying user selection.

AI summary
The present invention is a connection device for connecting a wiper blade extending in a longitudinal direction to an arm of a wiping system, the connection device including a connector configured to carry the wiper blade and a connection module adapted to be mounted on the connector and connected to the arm. The connection module including at least one base mounted pivotably about a pivot axis on the connector and a rotary platform mounted rotatably about a rotation axis on the base. The pivot axis and the rotation axis extending parallel to and separately from one another, the rotation axis being offset longitudinally relative to the pivot axis.
