Windshield Wiper Assembly With Rotating Segmented Cleaning Implements
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional windshield wiper assemblies have high configurational complexities and poor cleaning efficacy due to the use of a single wiper blade for various visibility-limiting matters, leading to reduced blade life and ineffective cleaning.
Innovation Solution
A windshield wiper assembly with a rotating mechanism and a plurality of detachable cleaning implements, such as a rain water blade, ice scraper, snow brush, and bug scrubber, coupled to a cuboidal wiper shaft, allowing selective contact with the windshield during oscillation for efficient cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single wiper blade is used for cleaning various visibility limiting matters, then the device complexity is reduced, but the cleaning efficacy and blade life deteriorate
Solution Approach 1:
The wiper blade is segmented into multiple cleaning implements (wiping element, scrubbing element, brushing element) that can be selectively positioned along the wiper arm. Each implement is optimized for specific cleaning tasks, allowing the system to handle various visibility-limiting matters effectively while maintaining manageable complexity through modular design
Solution Approach 2:
The wiper assembly is designed with multi-functional cleaning implements that can address different cleaning needs (wiping, scrubbing, brushing) within a single device. The adjustable positioning mechanism allows any implement to be placed at any location along the wiper arm, providing universal adaptability for various cleaning scenarios
2Device complexity
If a single wiper blade is used for various visibility limiting matters, then the device structure is simplified, but the blade life decreases
Solution Approach 1:
The wiper blade consists of multiple separate cleaning implements (wiping, scrubbing, brushing elements) that can independently wear and be replaced. This segmentation allows selective replacement of only the worn implement rather than the entire blade assembly, extending overall system life while maintaining simple device structure
Solution Approach 2:
The modular cleaning implements are designed to be replaceable when worn. Users can discard the worn implement and replace it with a fresh one, recovering the value of the remaining functional implements in the assembly and extending the overall service life of the wiper system
3Reliability
If multiple cleaning implements are added to the wiper assembly, then the cleaning efficacy is improved, but the configurational complexity increases
Solution Approach 1:
The wiper blade is divided into distinct functional segments (wiping, scrubbing, brushing elements) that operate independently. This segmentation improves cleaning efficacy for different types of contaminants while maintaining simple overall configuration through modular, replaceable components rather than integrated complex mechanisms
Solution Approach 2:
The wiper assembly includes an adjustable positioning mechanism that allows dynamic repositioning of cleaning implements along the wiper arm. This dynamic adaptability enables optimal placement of different implements for various cleaning tasks without requiring complex fixed configurations, improving cleaning efficacy while keeping the system relatively simple

AI summary
Disclosed is a windshield wiper assembly capable of being mounted on an oscillating wiper mechanism of a vehicle. The windshield wiper assembly comprises a cleaning unit and a rotating mechanism. The cleaning unit comprises a wiper shaft and a plurality of cleaning implements detachably coupled to a peripheral surface of the wiper shaft. The rotating mechanism is coupled to the cleaning unit. The rotating mechanism is capable of rotating the cleaning unit in a manner such that a cleaning implement from the plurality of cleaning implements is selectively brought into contact with a windshield of the vehicle and configured to clean the windshield upon oscillating the cleaning unit over the windshield.
