Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sun shading fabrics either fail to provide adequate shade or restrict air permeability, lacking a balance between blocking sunlight and allowing airflow.
Innovation Solution
A flexible sun shading fabric comprising multiple layers with consistently sized and equally spaced openings, arranged in offset rows to form a honeycomb-like structure, which minimizes sunlight penetration while allowing air to pass through, and optionally features a reflective or ultraviolet absorbent coating for added protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If sun shading fabric uses dense weaving or solid material to block sunlight, then shading effectiveness is improved, but air permeation is blocked
Solution Approach 1:
The fabric is segmented into multiple layers with regularly spaced openings in each layer. The openings are arranged in an offset pattern between layers, creating a multi-level filtering structure that blocks sunlight while maintaining air flow pathways through the segmented architecture.
Solution Approach 2:
The invention transitions from a two-dimensional flat fabric structure to a three-dimensional multi-layer configuration. By stacking layers with offset opening patterns, the fabric creates depth and spatial complexity that simultaneously achieves sunlight blocking and air permeation.
2Object-generated harmful factors
If sun shading fabric uses open mesh structure to allow air flow, then air permeation is improved, but sunlight blocking effectiveness deteriorates
Solution Approach 1:
The fabric combines multiple layers of material with specific opening patterns into a composite structure. Each layer contributes to the overall performance, creating a synergistic effect where the composite achieves both air permeability and sunlight blocking that single layers cannot achieve alone.
Solution Approach 2:
Multiple layers are nested together with each layer containing openings that are offset from adjacent layers. This nesting creates a hierarchical structure where smaller opening patterns in individual layers are nested within the larger multi-layer configuration, achieving cumulative shading effect while maintaining air flow.

AI summary
An air permeable sun shading fabric for provision of shade while allowing air to permeate the fabric includes a panel that is flexible and comprises a plurality of layers. The plurality of layers comprises an inner layer and an outer layer. Each of the layers has a plurality of openings. The openings are consistently sized and equally spaced, thus defining a band around each of the openings. The opening and a respective one of the bands define a unit. The openings of each of the layers are positioned in rows that are parallel. Each of the rows is offset by one half of the unit from adjacent rows. The layers are mutually coupled, such that each of the pluralities of openings is offset from the pluralities of openings positioned in adjacent layers.
