Rotatable Wiper Adapter Head for Universal Yoke Engagement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing windscreen wiper systems face challenges in designing a universal adapter that can easily and reliably connect wiper blades to various types of drive arm yokes and connectors, requiring an ergonomic and long-lasting solution for easy assembly and separation.
Innovation Solution
The adapter features a head and body with a means of connection in rotation to the wiper blade connector, including a housing for the drive arm yoke's upper wall and a rib, with a tooth and hook mechanism for secure engagement, allowing for easy assembly and disassembly by pivoting the head relative to the body.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a universal adapter is designed to connect wiper blades to various types of drive arm yokes, then adaptability is improved, but device complexity increases
Solution Approach 1:
The adapter body is designed with a standardized interface that can accommodate multiple types of drive arm yokes through a single universal connection mechanism, allowing one adapter to serve multiple functions across different wiper blade configurations
Solution Approach 2:
The adapter is divided into distinct functional segments: a standardized body for universal compatibility, a rotatable head for connection adjustment, and engagement means for securing to different yoke types, allowing each segment to be optimized independently
2Reliability
If a secure connection mechanism is implemented between wiper blade and drive arm, then reliability is improved, but ease of operation deteriorates
Solution Approach 1:
The head of the adapter is designed to rotate relative to the body, enabling dynamic adjustment and easy engagement/disengagement of the connection mechanism without requiring complex tools or procedures
Solution Approach 2:
The rotatable head acts as an intermediary element between the standardized adapter body and the connector, providing a simple rotational interface that secures the connection reliably while allowing easy operation for assembly and disassembly
3Ease of operation
If a rotatable head mechanism is added to the adapter, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The rotatable head is integrated with the adapter body as a unified structure where the head forms an extension of the body, reducing the need for separate fastening components and simplifying the overall assembly
