Universal Wiper Connector for Multi-Arm Compatibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wiper devices require multiple designs to accommodate various drive arm sizes and shapes, limiting design freedom and increasing production costs due to the need for exclusive wiper devices for each type of drive arm.
Innovation Solution
A wiper device with an adaptable assembly that includes a blade with rail springs, a seating plate, and a connector with interchangeable coupling mechanisms for different drive arm types, such as 'U'-shaped, bayonet, pin, and top lock, allowing for standardized production across various drive arm configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If wiper devices are designed exclusively for each type of drive arm, then compatibility with specific drive arms is improved, but device complexity and production costs increase
Solution Approach 1:
The connector is designed with a universal structure that can accommodate multiple drive arm types ('U'-shaped, bayonet, pin, top lock) through a single standardized interface, eliminating the need for separate wiper device designs for each drive arm variant
Solution Approach 2:
The wiper device is divided into separable components (blade assembly, connector, adaptor) that can be independently configured, allowing the same blade assembly to work with different drive arm types through connector variations
2Adaptability or versatility
If multiple exclusive wiper device designs are produced for various drive arms, then compatibility with specific drive arms is improved, but manufacturing costs increase
Solution Approach 1:
A single standardized connector design serves multiple drive arm types, enabling mass production of unified components and reducing manufacturing complexity and costs
Solution Approach 2:
The adaptor component can be discarded or replaced independently when changing drive arm types, while the main blade assembly and connector remain reusable, reducing waste and production costs
3Adaptability or versatility
If multiple exclusive wiper device designs are produced for various drive arms, then compatibility with specific drive arms is improved, but design freedom is reduced
Solution Approach 1:
The standardized connector provides a flexible platform that maintains design freedom while achieving universal compatibility, allowing designers to create one blade assembly that works across multiple drive arm configurations
