Wiper Deflector Spray Manifold for Uniform Windshield Wetting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing windshield wiper systems suffer from suboptimal wettability of the glass surface due to inadequate distribution and shape of cleaning fluid spray holes, leading to streaks and uneven coverage.
Innovation Solution
A wiper blade with a deflector featuring a spray ramp that includes a distribution tube and channels with a cross-section of 0.002 mm² to 0.070 mm² and 1 to 60 orifices per 10 mm, optimizing the distribution and misting of cleaning fluid for uniform coverage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional wiper blade assembly is used, then the wiper can clean the windshield, but the wiper blade assembly cannot be easily adjusted or removed
Solution Approach 1:
The wiper system is divided into distinct modular components: the wiper arm assembly and the wiper blade assembly. The wiper blade assembly can be independently removed from the wiper arm assembly by disengaging the retaining clip, allowing easy adjustment and replacement without affecting the entire wiper system.
Solution Approach 2:
The wiper blade assembly incorporates a pivotable connection to the wiper arm assembly, allowing it to rotate and adjust its position. This dynamic connection enables the wiper blade to be easily detached and reattached at different angles for optimal positioning.
2Ease of operation
If the wiper blade assembly is made adjustable and removable, then ease of operation improves, but the structural integrity and reliability may deteriorate
Solution Approach 1:
The connection system is segmented into discrete components including the retaining clip, mounting bracket, and pivot connection. This segmentation allows for simple assembly and disassembly while maintaining a secure connection during operation through the interlocking design of these components.
3Adaptability or versatility
If the wiper system uses a fixed blade assembly, then structural stability is maintained, but adaptability to different windshield conditions is reduced
Solution Approach 1:
The wiper blade assembly is designed with a pivotable connection that allows it to rotate relative to the wiper arm assembly. This dynamic capability enables the blade to be adjusted to different angles and positions to adapt to various windshield conditions and shapes while maintaining structural stability through the rigid mounting bracket and retaining clip during operation.
