Linear Drive Louvered Roof with Aerodynamic Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional louvered roof systems face issues such as gaps between panels allowing rain or snow entry and water damage to motor components due to improper design and placement of motor assemblies within the gutter's water flow area.
Innovation Solution
The use of aerodynamically shaped louvers that overlap tightly to prevent rain and snow entry, combined with a direct coupling of a linear drive motor to the louver assembly, eliminating the need for external gear systems and ensuring smooth operation by attaching the motor directly to the louvers, thus avoiding water damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional parallel louvers are used in louvered roof systems, then the structure is simple to manufacture, but gaps between panels allow rain or snow to enter and wind damage occurs
Solution Approach 1:
The louver panels are designed with aerodynamic curved surfaces rather than flat parallel shapes. The curved configuration allows adjacent louvers to overlap and interlock effectively, creating a watertight seal that prevents rain and snow penetration while maintaining structural integrity against wind forces.
2Device complexity
If motor assemblies are placed within the gutter's water flow area, then the drive system is compact, but water damage and short circuits occur
Solution Approach 1:
The motor assembly is extracted from the vulnerable gutter water flow area and repositioned to a protected location. This separation removes the motor from direct exposure to water while maintaining the compact overall structure of the louvered roof system.
3Ease of manufacture
If external gear systems are used to move louvers, then the drive mechanism is simple to implement, but periodic maintenance and replacement are required
Solution Approach 1:
The traditional mechanical gear system is replaced with a linear drive motor system that directly actuates the louver panels. This substitution eliminates external gears, belts, and other mechanical transmission components that require periodic maintenance and replacement, resulting in a maintenance-free drive mechanism.

AI summary
A new louver, and a louvered roof assembly having a plurality of these louvers is provided wherein the plurality of louvers, are movable within a frame between an open condition and a closed condition. The louvers, each having first and second ends, are pivotally coupled to the frame for rotation about an axis. A linear drive motor is coupled to a moveable arm bar to which each louver is connected by a pin which pin is attached at the pin's opposite end to a member disposed within the center of each respective louver. Single set and dual sets of louvers may be operated by a single linear drive actuator.
