Vehicle Window Corner Piece Water Drainage Path
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Water often accumulates and drips inside vehicle doors during rainfall, potentially damaging electronics by infiltration and freezing.
Innovation Solution
A hydrophilic corner piece is attached to the vehicle window, angled and shaped to direct water along a specific drainage path, using a hydrophilic material or coating, and secured with adhesive, creating a funnel-like shape to channel water away from the door interior.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If water naturally flows around the window, then water management is simple, but water drips inside the vehicle door causing damage
Solution Approach 1:
The corner piece is divided into multiple functional surfaces: a first surface that receives water, a second surface that directs water, and a third surface that channels water away. This segmentation of the water management function into distinct surfaces allows effective water redirection while maintaining a relatively simple integrated component structure.
Solution Approach 2:
The corner piece acts as an intermediary component between the window and the door, intercepting water flow and redirecting it away from the door interior. This mediator component protects the door electronics from water damage without requiring modification of the window or door structures themselves.
2Reliability
If a corner piece is added to manage water flow, then water drainage is improved, but manufacturing complexity increases
Solution Approach 1:
The corner piece combines multiple water management functions into a single integrated component. By merging the water receiving, directing, and channeling functions into one piece, the design simplifies the overall manufacturing process compared to using multiple separate components, while still achieving effective water drainage.
Solution Approach 2:
The corner piece incorporates curved surfaces and rounded edges to facilitate smooth water flow transitions. The curved geometry naturally guides water along the desired path without requiring complex mechanical features or moving parts, simplifying manufacturing while improving drainage efficiency.
3Reliability
If the corner piece is angled to direct water, then water redirection is effective, but installation complexity increases
Solution Approach 1:
The corner piece features an asymmetric design with specific angles and orientations optimized for water redirection. The asymmetric geometry is designed to self-align during installation, with the angled surfaces naturally positioning themselves to receive and redirect water flow, reducing the need for complex alignment procedures.
Solution Approach 2:
The corner piece is pre-configured with the optimal angles and orientations for water redirection during manufacturing. This preliminary preparation of the correct geometry eliminates the need for field adjustments or complex alignment procedures during installation, simplifying the installation process while maintaining effective water flow direction.
