Woven Vertical Blind Structure for Light Control and Ventilation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional vertical blinds face challenges in air ventilation while blocking sunlight, with complex component structures and high fabrication costs, and aesthetic issues due to different materials for curtain bands and blinds.
Innovation Solution
A vertical blind system where fabric louvers with a constant width are woven into a mesh structure with a curtain section, allowing for adjustable lighting and improved ventilation, using low-melting fibers and flame retardant threads, and a panel-type slat for durability, with a rubber thread to prevent folds and enhance aesthetics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If traditional vertical blinds with separate curtain bands and blind components are used, then lighting control is achieved, but air ventilation is blocked and fabrication costs increase
Solution Approach 1:
The patent merges the curtain band and blind components into a single integrated woven structure. The curtain section and fabric louvers are woven together as one unified component, eliminating the need for separate curtain bands, multiple clips, and assembly steps. This integration maintains lighting control functionality while reducing fabrication complexity and costs.
Solution Approach 2:
The integrated woven structure serves multiple functions simultaneously: it provides lighting control through louver rotation, enables air ventilation through the mesh structure, and eliminates the need for separate connection components. This multi-functionality resolves the contradiction by achieving lighting control without the added cost and complexity of separate components.
2Illumination intensity
If traditional vertical blinds with separate curtain bands and blind components are used, then lighting control is achieved, but device complexity increases
Solution Approach 1:
The patent combines multiple separate components (curtain band, clips, louvers) into a single integrated woven structure. The curtain section and fabric louvers are woven together as one unified component, dramatically reducing the number of parts and simplifying the overall device structure while maintaining lighting control capability.
3Illumination intensity
If traditional vertical blinds with separate curtain bands and blind components are used, then lighting control is achieved, but aesthetic property deteriorates
Solution Approach 1:
The patent uses the same fabric material for both the curtain section and the fabric louvers, creating a homogeneous appearance. The integrated woven structure ensures consistent texture, color, and material throughout, eliminating the aesthetic discontinuity caused by different materials in traditional separate-component designs.
4Illumination intensity
If traditional vertical blinds are used to block sunlight, then lighting control is achieved, but air ventilation is hindered
Solution Approach 1:
The patent applies different structural characteristics to different parts of the same component: the fabric louvers provide light blocking capability while the mesh structure of the curtain section maintains air permeability. This local differentiation within the integrated structure allows simultaneous light control and ventilation.
Solution Approach 2:
The curtain section employs a mesh structure that is porous and permeable to air, allowing ventilation to proceed even when the fabric louvers are in the light-blocking position. The mesh structure enables air passage while the integrated design maintains overall functionality.
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
Facilitates smooth air ventilation and adjustable lighting while maintaining durability and safety, reducing component complexity and fabrication costs, and enhancing the aesthetic appeal by integrating the curtain and blind functions into a cohesive unit.
Implementation Method 1
a low-melting fiber is used as the woof for forming the curtain section and the fabric louver, and the blind sections are directed to pass through a tenter to melt the low-melting fiber so that the shape of the blind section can be maintained
Implementation Method 2
a rubber thread is interlaced with woofs of the curtain section and the united section to prevent folds from occurring in the blind section

AI summary
A vertical blind united by weaving and a method of fabricating the same are disclosed, wherein a plurality of fabric louvers 20 each having a constant width are arranged at a regular interval in one surface of a curtain section 10 having a predetermined area resulting from a mesh structure, the curtain section 10 is united with the fabric louvers 20 by weaving along longitudinal edges of the fabric louvers 20, and upper ends of the fabric louvers 20 are applied to a typical vertical blind structure, so that lighting is adjusted by rotation of the fabric louvers and air ventilation through the curtain section 10 is facilitated.
