Window Wire Regulator Eaves Structure for Rainwater Bypass
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Rainwater entering the window glass of a vehicle can cause rusting and operation failures in the wire regulator due to freezing and adherence, despite existing rain gutters that fail to prevent water from bypassing and reaching critical components.
Innovation Solution
A wire regulator design featuring first and second rainwater guide parts with overlapping eaves that redirect water away from critical components, preventing entry into the ascending and descending wire end housing parts and gutters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single layer of eaves is provided to guide rainwater, then the structure is simple, but rainwater can bypass from the lower surface due to surface tension and enter critical components
Solution Approach 1:
The rainwater guide part is divided into multiple layers (first eaves and second eaves) arranged in the vertical direction. This segmentation creates multiple barriers against rainwater, preventing bypass through surface tension while maintaining effective protection of critical components.
Solution Approach 2:
The solution transitions from a single-layer (2D) eaves structure to a multi-layer (3D vertical arrangement) structure. By adding the vertical dimension with overlapping first and second eaves, the system effectively blocks rainwater pathways that would bypass a single layer.
2Reliability
If rainwater enters the wire end housing part or adheres to wires and guide rails, then freezing or rusting occurs causing operation failure, but adding protective structures increases device complexity
Solution Approach 1:
The rainwater guide part is segmented into multiple functional layers (first eaves for initial deflection, second eaves for secondary protection) that work together to prevent water entry. This segmented approach provides comprehensive protection while keeping each individual component relatively simple.
Solution Approach 2:
The multi-layer eaves structure acts as an intermediary barrier between rainwater and critical components (wire end housing part, wires, guide rails). This intermediary structure redirects water away before it can cause freezing or rusting, protecting the underlying components.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Prevents water from entering and adhering to the wire and guide rail, thereby avoiding freezing and rusting, ensuring the regulator's operational reliability.
Implementation Method 1
part of rain water having hit an upper surface of the eaves goes around to a lower surface of the eaves from an end of the eaves due to a surface tension

AI summary
A task is to provide a wire regulator that can prevent a wire and a guide rail from rusting and prevent an operation failure of the wire regulator. A first rain water guide part 170 that prevents rain water from entering an ascending wire end housing part 157, a descending wire end housing part 163 and a gutter part 161 is provided at a part above a lower end of the ascending wire end housing part 157 of a slider 103, and the first rain water guide part 170 includes first eaves 171, and second eaves 173 that overlap the first eaves 171 on a lower side of the first eaves 171 and in a drop direction R of the rain water.
