Sun Protection Installation Single Drive Synchronization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sun protection installations face synchronization challenges when using two independent drive systems for deploying slats in opposite directions, leading to difficulties in maintaining consistent spacing and efficient sunlight distribution.
Innovation Solution
The implementation of a rail with a sliding strip and lateral guidance, along with carriage connecting elements that maintain a constant distance between slats, allows for simultaneous displacement and rotation of blades, using a gear system and low-friction materials to ensure smooth movement and prevent blockages.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If two independent drive systems are used to deploy blade subsets in opposite directions, then deployment flexibility is improved, but synchronization control becomes difficult
Solution Approach 1:
The patent merges the two independent drive systems into a single drive system that controls both blade subsets simultaneously. The single drive system operates a common belt that is coupled to both subsets, ensuring synchronized deployment while maintaining the flexibility to deploy blades in opposite directions. This resolves the synchronization control difficulty while preserving deployment flexibility.
2Illumination intensity
If blades are deployed in opposite directions from the center, then sunlight distribution is improved, but mechanical synchronization becomes tricky
Solution Approach 1:
The patent uses a single drive system with a common belt to mechanically link both blade subsets, ensuring they deploy symmetrically in opposite directions from the center. This mechanical coupling through the shared belt and single drive system guarantees reliable synchronization while achieving even sunlight distribution through the roof.
3Device complexity
If a single drive system is used to move blades in opposite directions, then device complexity is reduced, but achieving symmetric deployment becomes challenging
Solution Approach 1:
The patent employs an asymmetric belt configuration where the belt is coupled to blade subsets at different locations along its length. This asymmetric coupling arrangement, combined with the single drive system, naturally produces symmetric deployment of blades in opposite directions from the center, achieving manufacturing precision without increasing device complexity.
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
This solution enables even sunlight distribution by maintaining a constant gap between deployed slats while keeping others grouped, simplifying the deployment process and reducing the risk of mechanical issues, thus providing effective sun protection.
Implementation Method 1
the sliding pad is made of a material characterized by a coefficient of friction less than or equal to 0.34, and the sliding strip is made of a material characterized by a coefficient of friction less than or equal to 0.1
