High definition screen materials

Solution Overview

Problem

Existing insect screens compromise visibility and airflow due to their woven construction, and there is a need for improved materials that effectively exclude small insects while minimizing impact on light transmission and optical clarity.

Innovation Solution

A screen material composed of polymer-coated threads with a denier of 420 or less, typically 250, and a diameter of 0.3 to 0.4 mm, woven in a mesh count ranging from 16×14 to 24×24, using polymers like PVC-coated polyester, which enhances light transmission and optical clarity.

1Object-affected harmful factors

If traditional woven insect screens are used, then insect exclusion is effective, but light transmission and optical clarity are compromised

Engineering Contradiction:

Improveinsect exclusionVSAvoidlight transmission

Core Design Contradiction:

Object-affected harmful factorsVSIllumination intensity

Solution Approach 1:

The patent applies parameter changes by reducing the denier of screen threads from traditional values (typically 420 or higher) to 420 or less, with specific embodiments using 360, 300, 250, or even 190 denier. This parameter reduction allows the screen to exclude insects while minimizing visual obstruction and maximizing light transmission, directly resolving the contradiction between insect exclusion effectiveness and light transmission.

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent employs composite materials by combining polymer-coated threads (such as PVC-coated polyester) with optimized denier specifications. The composite structure of coated polyester threads provides both the mechanical strength needed for insect exclusion and the optical properties for improved light transmission, resolving the contradiction between effective insect blocking and maintaining illumination.
