Louver Canopy Guide Groove Rainwater Drainage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing canopies face issues with water leakage due to wear and deterioration of sealing rings and accumulation of objects on the canopy during rain, which complicates maintenance and increases manufacturing costs.
Innovation Solution
The louver canopy design features a frame with obliquely extending rafters and louvers that rotate to form guide grooves for rainwater and object drainage, eliminating the need for sealing rings and facilitating easy object removal through gravity and water flow, while maintaining ventilation and light adjustment capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If sealing rings are used to prevent water leakage, then water sealing performance is improved, but the sealing rings wear and deteriorate after multiple opening and closing operations, causing water leakage
Solution Approach 1:
The patent removes the sealing rings from the louver structure entirely. Instead of using separate sealing components that wear over time, the flashing itself is designed with an integrated L-shaped cross-section that provides both structural support and water sealing functionality. This eliminates the sealing rings and their associated wear and replacement issues.
Solution Approach 2:
The patent combines the structural support function and water sealing function into a single integrated component - the flashing. The L-shaped cross-section of the flashing integrates the vertical web (for structural support) and the horizontal flange (for water sealing) into one piece, eliminating the need for separate sealing rings and reducing the number of components that can wear or fail.
2Ease of operation
If flushing or blowing devices are added to clean objects from the canopy, then cleaning effectiveness is improved, but manufacturing costs and structural complexity increase
Solution Approach 1:
The patent designs the louver system to clean itself using the existing rainwater flow. The inclined top surface and the guide grooves work together to channel water and dislodged objects directly into the gutters without requiring any additional cleaning devices. The system uses the natural rainwater flow to perform the cleaning function that would otherwise require complex flushing or blowing devices.
Solution Approach 2:
The patent converts the potentially harmful effect of rainwater (which can cause water leakage and object accumulation) into a beneficial cleaning force. By designing inclined surfaces and guide grooves, the rainwater flow is directed to automatically flush objects off the louver surfaces and into the drainage system, turning a problem into a self-cleaning mechanism.
3Ease of operation
If objects accumulate on the canopy during rain, then cleaning difficulty increases, but adding lifting devices to facilitate cleaning increases manufacturing costs
Solution Approach 1:
The patent designs the louver top surface with a uniform incline that creates a consistent gravitational force component acting on objects. This inclined surface ensures that objects naturally slide downward under gravity without requiring additional lifting or mechanical assistance, making the system inherently easy to clean and reducing manufacturing costs.

Function Achieved in This Case
This design prevents water leakage and object accumulation, simplifies maintenance by allowing rainwater to drain and objects to slide off, reducing maintenance complexity and manufacturing costs, and enhances ventilation and light penetration.
Implementation Method 1
the guide groove has two outlets respectively disposed at two ends of the guide groove... rainwater to drain and objects to slide off

AI summary
A louver canopy comprises a frame with a top disposed with parallel rafters; a plurality of louvers rotationally connected between the rafters and sequentially arranged along a length direction of the rafters, the louvers are disposed at intervals and parallel to each other, each of the louvers includes an elongated flashing; a baffle connected to a first long side of the flashing; an elongated first guide groove formed between the baffle and the flashing; When the louvers rotate to a closed state, an opening of the first guide groove faces upward, and a second long side of the flashing passes over a top of the baffle of an adjacent louver of the louvers and positions above the first guide groove of the adjacent louver.
