Louver Blade Drainage With Flexible Baffle for Reduced Opening Drips
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Louvered shelters experience water dripping into the room when transitioning from a closed to an open state due to water remaining on the louver blades, which affects user experience.
Innovation Solution
A louver blade design featuring a drainage groove with a baffle plate that switches between natural and stressed states to direct water into the groove, and a waterproof edge to prevent water from dripping when the blades rotate, using materials like rubber or silicone for the baffle plate to ensure effective water management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the louver blade rotates to the open state, then the ventilation and lighting performance is improved, but water drips into the room along the tilted louver blade
Solution Approach 1:
A baffle plate is introduced as an intermediary component between the louver blade surface and the drainage groove. The baffle plate intercepts water flowing down the louver blade and redirects it into the drainage groove, preventing water from dripping into the room while maintaining the open state ventilation function
Solution Approach 2:
The drainage groove is designed to extend upward along the louver blade surface in the vertical dimension, creating a water collection path that follows the water flow direction. This vertical extension of the drainage groove, combined with the baffle plate, effectively captures water at multiple heights along the blade
2Reliability
If the baffle plate height is increased to improve water blocking, then the drip-proof effect is enhanced, but the closed state flat surface is compromised
Solution Approach 1:
The baffle plate is designed as a movable component that can dynamically change its position between two states: extended upward to block water during the open state, and flattened against the louver blade surface during the closed state. This dynamic adjustment allows the system to maintain both the drip-proof effect and the flat surface requirement at different operational stages
Solution Approach 2:
The height parameter of the baffle plate is made variable rather than fixed. The baffle plate can change its effective height from a low position (when flattened) to a high position (when extended), allowing the system to adapt the water blocking capability to the operational state of the louver blade
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
The design effectively reduces water dripping by guiding it into the drainage groove, protecting internal components and improving user experience by preventing water accumulation and immersion.
Implementation Method 1
the water remaining on the top surface of the louver blade can flow into the drainage groove under the blocking action of the baffle plate
Implementation Method 2
The elastic baffle plate can deform to reduce a height of its top end in a stressed state
Implementation Method 3
the water (which is mainly rainwater, but can also be water produced by washing the top surface of the louver blade) on the top surface of the louver blade will concentrate on flowing to a drainage groove with a lower position

AI summary
The embodiments of the present invention provide a louver blade, a louvered roof, and a viewing shelter, and relate to the field of roofs. A drainage groove is arranged on one side of the body of the louver blade (200); the drainage groove includes a groove wall (302) located on an outer side of the body (300); and a baffle plate (340) is further arranged on a top of the groove wall (302). When the body (300) is arranged horizontally, a top end of the groove wall is not higher than a top surface of the louver blade, and the baffle plate can switch between a natural state and a stressed state, wherein a top end of the baffle plate in the natural state is higher than the top end of the groove wall, and a height of the top end of the baffle plate can be reduced in the stressed state. The louvered roof includes a shelter frame (120) and a plurality of louver blades (300) above, wherein when the plurality of louver blades are in the closed state on the shelter frame, the other side of one of the louver blades relative to the drainage groove presses against the baffle plate (340) of the adjacent louver blade, so that the baffle plate switches to the stressed state; and when the louver blades rotate to an open state, the baffle plate of the louver blade switches to the natural state. The louver blade (300), louvered roof, and viewing shelter in the embodiments of the present invention can reduce dripping water from the louver blade when rotating to open, thereby improving the user experience.
