Rotatable Wiper Blade Adapter for Compact Vehicle Window Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wiper blade and arm configurations result in a relatively large distance from the vehicle window and are not adaptable to varying bonnet and window geometries, limiting their space-saving and variable arrangement.
Innovation Solution
The wiper blade adapter features two sections at an oblique angle, allowing for a more compact and adjustable arrangement with the wiper arm, and includes a washing liquid supply system integrated into the adapter elements, with a flexible hose and locking mechanism for secure mounting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the wiper arm is arranged above the wiper blade in alignment with the wiper blade longitudinal axis, then the wiper blade can be easily mounted and operated, but the distance from the vehicle window becomes relatively large and the arrangement becomes less space-saving
Solution Approach 1:
The patent applies dynamics by making the adapter element rotatable about an axis, allowing the wiper blade to be adjusted to different angular positions relative to the wiper arm. This enables the wiper blade to be oriented at an optimal angle to reduce the distance from the vehicle window while maintaining ease of mounting through the rotatable connection mechanism.
2Ease of manufacture
If the wiper blade and wiper arm are arranged in a fixed geometric configuration, then the mounting is simplified, but the adaptability to different bonnet and window geometries is limited
Solution Approach 1:
The rotatable adapter element provides dynamic adjustability, allowing the wiper blade assembly to adapt to different bonnet and window geometries by changing its angular orientation while maintaining a simple fixed mounting structure. The rotation capability enables versatility without complicating the mounting process.
Solution Approach 2:
The adapter element is segmented into a rotatable connection interface between the wiper blade and wiper arm, allowing independent adjustment of the blade orientation while keeping the wiper arm mounting fixed. This segmentation enables adaptability to different geometries without requiring complex adjustable mounting mechanisms.
3Device complexity
If the adapter element is made as a single integrated component, then the device complexity is reduced and production costs are lowered, but the adjustability and adaptability are limited
Solution Approach 1:
The single integrated adapter element incorporates a rotatable connection mechanism that provides adjustability within the unified structure. This dynamic feature allows the adapter to adapt to different orientations and geometries while maintaining low device complexity and avoiding the need for multiple separate adjustable components.
