Electrical Panel Water Barrier System with Weep Holes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electrical panels lack effective water barriers, leading to water intrusion and leakage due to improper installation and environmental exposure, which can damage electrical components and compromise safety.
Innovation Solution
The electrical panel incorporates flanges to divide it into front and rear portions, along with a water barrier system that includes weep holes, channels, and troughs to direct and prevent water migration, ensuring water does not enter the rear portion and is drained away from electrical components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the electrical panel is mounted in a semi-flush manner with flanges extending from the panel, then the panel can be securely coupled to the structure, but gaps are formed between the flanges and surrounding materials that allow water intrusion
Solution Approach 1:
The electrical panel is divided into a front portion and a rear portion by the flange structure. The barrier extends from the interior surface to divide the interior portion, creating separate zones for water management and electrical components.
Solution Approach 2:
A barrier is introduced as an intermediary element between the front and rear portions of the electrical panel. This barrier extends from the interior surface toward the flanges to block water migration while allowing the flanges to maintain their coupling function.
2Ease of manufacture
If gaps are formed between layers of material and the electrical panel during installation, then the panel can be installed through the wall structure, but water can penetrate through these gaps and reach electrical components
Solution Approach 1:
The barrier is pre-installed on the interior surface of the electrical panel before the panel is mounted to the structure. This preliminary action ensures water protection is in place before any gaps can form during the installation process.
Solution Approach 2:
The barrier divides the interior portion into a front portion and a rear portion, creating separate zones that isolate electrical components from water that may enter through installation gaps.
3Device complexity
If no water barrier is provided, then the electrical panel structure remains simple, but water can migrate from the front portion to the rear portion and damage electrical components
Solution Approach 1:
The interior portion is segmented by the barrier into distinct front and rear zones. This segmentation creates a water barrier that prevents migration while maintaining a relatively simple overall panel structure.
Solution Approach 2:
The barrier is extracted as a separate component that can be attached to the interior surface of the panel. This approach adds water protection functionality without requiring a complete redesign of the panel structure.

AI summary
A water barrier system for use in conjunction with an electrical panel to control water intrusion into and within the electrical panel is disclosed. In use, the water barrier system provides one or more barriers to prevent, or at least inhibit, water from entering the electrical panel, and/or to direct water, which has entered the electrical panel. The water barrier system may include one or more barriers extending from an interior surface of the electrical panel to block the migration of water, one or more weep holes in fluid communication with one or more channels to direct water that encounters or comes into contact with a top surface of the electrical panel, and/or one or more troughs to direct water that encounters or comes into contact with the top surface of the electrical panel.
