Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing transmission structures for long louver canopies suffer from distortions and functional failures due to the driving mechanism being mounted on one side, leading to incomplete closure and asynchronous motion of louver boards.
Innovation Solution
A stable transmission structure with a driving mechanism mounted on the middle beam, utilizing a transmission rod to synchronize the motion of louver boards, comprising a rotating part, transmission part, and linkage bars, with a rectangular and irregularly shaped cross-sections for balanced power transfer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the driving mechanism is mounted on one side of the louver canopy, then the structure is simpler, but the louver boards experience distortion and fail to close completely
Solution Approach 1:
The patent divides the transmission system into multiple independent transmission rods (first transmission rod and second transmission rod) that extend along the louver boards. This segmentation allows the driving force to be distributed evenly across multiple points, preventing distortion while maintaining structural simplicity.
Solution Approach 2:
The patent transitions from a single-point driving mechanism to a distributed linear transmission system. The transmission rods extend along the length of the louver boards, adding a dimensional aspect to the force distribution that ensures uniform motion and complete closure without distortion.
2Length of stationary object
If the transmission rod length increases to cover long louver canopies, then the coverage area increases, but the pipe distorts and functional failures occur
Solution Approach 1:
Instead of using a single long transmission rod, the patent employs multiple transmission rods distributed along the louver boards. Each rod maintains optimal length and stability, while collectively covering the entire canopy span without experiencing distortion.
Solution Approach 2:
The patent applies transmission rods at specific locations along the louver boards rather than using one continuous long rod. This local quality approach ensures that each transmission rod operates within stable dimensional limits while achieving overall system coverage.
3Device complexity
If the driving mechanism drives one end of the louver boards, then the mechanism structure is simpler, but the other end fails to close completely
Solution Approach 1:
The patent uses multiple transmission rods connected to the louver boards at different positions. This segmentation ensures that the driving force is applied uniformly across all louver boards, achieving precise synchronous closure without increasing the complexity of the driving mechanism itself.
Solution Approach 2:
The patent combines multiple transmission rods into a coordinated system that works together to drive the louver boards. This merging of transmission elements ensures synchronous motion and complete closure while maintaining a relatively simple driving mechanism configuration.

AI summary
The utility model pertains to the field of outdoor supplies and specifically relates to a stable transmission structure for a long louver canopy. The stable transmission structure for a long louver canopy comprises a tent frame, a driving mechanism is mounted in the middle part of the upper end of the tent frame in a fit manner, two ends of the driving mechanism are in transmission fit with a transmission rod, the transmission rod is in transmission fit with a louver transmission mechanism, and the louver transmission mechanism is used for driving ends of louver boards to flip, thereby achieving opening and closing of the louver boards. The driving mechanism in the present utility model is mounted on the middle beam and drives the louver transmission mechanism on the two sides by means of the transmission rod to open and close the louver boards. As the driving mechanism is on the middle beam, the errors and torsions after conduction to the two sides are similar, thereby achieving synchronous motions on the two sides and avoiding distortion of the louver boards.
