Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for creating heat-shielding clothing are complex, require multiple dye baths, and vary in quality, with lightly-colored fabrics offering poor heat shielding and deeply-colored fabrics being more effective, while also lacking in antibacterial and deodorizing properties.
Innovation Solution
A cool-feeling fiber fabric is developed using ultrafine titanium oxide particles for UV reflection and fine titanium oxide particles for IR reflection, combined with silver zeolite and a binder resin, applied uniformly across various fiber types, providing efficient diffuse reflection and antibacterial/deodorizing properties.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If dye is used to provide heat shielding effect, then heat shielding property is improved, but manufacturing complexity increases and quality variation occurs
Solution Approach 1:
The patent introduces inorganic particles (titanium oxide, zinc oxide) as intermediary substances that provide heat shielding function without requiring complex dyeing processes. These particles are applied directly to the fabric surface through coating or impregnation methods, serving as a mediator between the fabric and sunlight to achieve heat rejection while simplifying manufacturing compared to multi-bath dyeing processes.
Solution Approach 2:
The patent changes the approach from chemical parameter modification (dye concentration, color depth) to physical parameter modification (particle size distribution, particle composition). By controlling particle size parameters (ultrafine particles 0.1-10 μm, fine particles 10-100 μm) and their composition ratios, the heat shielding effect is optimized without the quality variation issues associated with dye concentration control.
2Loss of energy
If high concentration dye is used for heat shielding, then heat shielding effect is improved, but manufacturing complexity and quality control difficulty increase
Solution Approach 1:
The patent transitions from controlling chemical parameters (dye concentration) to controlling physical parameters (particle size distribution, particle composition ratios). The use of ultrafine particles (0.1-10 μm) and fine particles (10-100 μm) with specific size ranges and composition ratios provides consistent heat shielding performance without the quality variation inherent in high-concentration dyeing processes.
Solution Approach 2:
The patent employs composite material structures combining different types of inorganic particles (titanium oxide, zinc oxide) with complementary properties. This composite approach ensures consistent heat shielding performance across batches, as the physical and chemical properties of inorganic particles are more stable and predictable compared to organic dyes, thereby improving manufacturing precision and quality consistency.
3Loss of energy
If conventional heat shielding methods are used, then heat shielding is provided, but antibacterial and deodorizing properties are lacking
Solution Approach 1:
The patent applies multi-functionality by selecting inorganic particles that simultaneously provide heat shielding and antibacterial properties. Titanium oxide and zinc oxide particles serve dual functions: they reflect and scatter infrared and ultraviolet radiation for heat shielding, while also exhibiting antibacterial activity and deodorizing properties. This eliminates the need for separate functional treatments and enhances the versatility of the fabric.
4Loss of energy
If fiber material and dye are selected according to fiber composition, then heat shielding is achieved, but process complexity increases with two bath or three bath dyeing
Solution Approach 1:
The patent replaces the complex intermediary process of multi-bath dyeing with a direct application method using inorganic particles. Instead of requiring sequential dyeing baths for different fiber types, the inorganic particles can be uniformly applied to mixed-fiber fabrics through coating or impregnation processes, significantly simplifying manufacturing while maintaining heat shielding effectiveness.
