Textile Blind Slat Structure Without Edge Slits
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Venetian blind slats made of traditional hard materials face issues such as high production costs, environmental impact, limited customization, poor waterproofing, and sunlight penetration due to slits, and rapid aging when exposed to sunlight, while soft materials like textiles lack the necessary hardness, waterproofing, and UV resistance.
Innovation Solution
A textile blind slat is developed by weaving an elongated textile strip with double-layered longitudinal edges to form inner chambers, which are hardened with a mixture of rigid polyacrylate latex, thermoplastic polyurethane emulsion, and flame retardant agents, and reinforced with elastic poles, eliminating the need for edge slits and allowing for customizable width and improved durability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If hard materials (aluminum alloy, wood, bamboo) are used for blind slats, then the slats have sufficient hardness and structural integrity, but the production cost increases and environmental impact worsens
Solution Approach 1:
The patent uses composite materials by combining textile (providing flexibility and comfort) with hardening agents and elastic poles (providing structural integrity and hardness). This composite approach allows the blind slat to achieve the required hardness without using expensive or environmentally harmful hard materials like aluminum alloy, wood, or bamboo, thereby reducing production cost and environmental impact while maintaining functional performance.
2Strength
If hard materials are used for blind slats, then the slats maintain predetermined standard widths, but adaptability to non-standard window sizes is lost
Solution Approach 1:
The patent applies dynamics by making the blind slat width adjustable rather than fixed. The textile material allows the slat width to be modified according to customer requirements and window sizes, while the elastic poles and hardening agents ensure the slat maintains sufficient structural integrity during use. This dynamic adaptability resolves the contradiction between structural integrity and adaptability to non-standard window sizes.
3Ease of operation
If slits are opened at edge portions for rope passage, then the blind slats can be connected, but sunlight penetration occurs affecting shading effect
Solution Approach 1:
The patent extracts or eliminates the harmful feature (slits for rope passage) by using alternative connection methods. Instead of opening slits that compromise shading, the invention uses edge portions with double layered structure that can be connected through other means (such as surface-mounted connectors or integrated rope systems) that do not require penetrating openings. This removes the source of sunlight penetration while preserving the connection function.
4Ease of manufacture
If plastic or resin is used for blind slats, then production cost is reduced, but the slats age quickly when exposed to sunlight
Solution Approach 1:
The patent uses composite materials by combining textile (providing UV resistance and durability) with hardening agents (providing structural stability). This composite structure maintains the cost advantages of textile materials while significantly improving resistance to sunlight aging and environmental degradation, resolving the contradiction between production cost and reliability.
5Ease of manufacture
If textile is used for blind slat, then the material is flexible and cost-effective, but the textile lacks hardness and waterproof properties
Solution Approach 1:
The patent applies parameter changes by treating the textile with hardening agents that chemically or physically modify the textile properties. This process transforms the textile from a soft, flexible material into a hardened material with sufficient structural integrity and improved resistance to moisture and environmental factors, while maintaining the cost-effectiveness and flexibility advantages of textile materials.
