Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing anti-glare devices are complex to produce, aesthetically unappealing, and do not efficiently reduce glare while maintaining light intensity, as they either rely on intricate grilles or materials that attenuate light in all directions.
Innovation Solution
An anti-glare device comprising a textile material with specific web and opening dimensions, attached to a frame, which effectively reduces lateral light radiation by creating a network structure that scatters light and maintains aesthetic appeal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a grille with louvres and side walls is used to reduce lateral radiation, then glare protection is improved, but device complexity increases
Solution Approach 1:
The patent replaces the complex rigid grille structure with a flexible textile material that has a three-dimensional loop pattern. This textile screen achieves the same glare protection function through its geometric structure rather than through complex mechanical components, thereby simplifying the device while maintaining effectiveness.
Solution Approach 2:
The textile material functions as a porous structure with interconnected loops and openings. This porous geometry allows light to pass through while the three-dimensional loop pattern scatters and blocks lateral radiation, achieving glare protection without requiring solid opaque materials or complex mechanical assemblies.
2Object-affected harmful factors
If a translucent material is stretched in front of a light source to shield it, then glare protection is improved, but light intensity in all directions is reduced
Solution Approach 1:
The textile screen has varying properties at different locations and orientations. The three-dimensional loops are arranged to provide different levels of light transmission and scattering in different directions, allowing optimal glare protection while maintaining high light intensity in the forward direction where illumination is needed.
Solution Approach 2:
The patent transitions from a two-dimensional flat screen to a three-dimensional loop structure. This additional dimension allows the material to scatter light laterally for glare protection while maintaining open pathways for forward light transmission, thereby protecting against glare without significantly reducing overall light intensity.
3Object-affected harmful factors
If a slat arrangement is used to prevent direct view of light sources, then glare protection is improved, but aesthetic appeal deteriorates
Solution Approach 1:
The flexible textile material with its three-dimensional loop pattern creates a visually appealing fabric-like appearance rather than the harsh, industrial look of rigid slat arrangements. The textile can be manufactured in various colors and patterns, enhancing aesthetic appeal while maintaining glare protection functionality.
4Object-affected harmful factors
If multiple tubes are used in a slat arrangement, then glare protection is improved, but manufacturing cost increases
Solution Approach 1:
The patent combines multiple functions into a single textile screen component. The three-dimensional loop pattern simultaneously provides glare protection, light diffusion, and structural support, eliminating the need for multiple separate tubes, slats, or mechanical components that would increase manufacturing complexity and cost.
Solution Approach 2:
The patent changes the fundamental parameter of the anti-glare structure from rigid mechanical components to a flexible textile material with specific geometric parameters. This material can be manufactured using textile manufacturing processes which are generally more cost-effective and scalable than precision mechanical fabrication, thereby reducing manufacturing costs.
