One-Piece Sunshade Blade Structure for Solar Opacity and Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional sunshade devices with fixed blades face manufacturing complexities and aesthetic issues due to the need for multiple parts and high accuracy in angular positioning, which complicates the production of disjointed elongated surfaces oriented perpendicular to the sun, affecting opacity and transparency.
Innovation Solution
The design of a single-piece blade with solid, elongated, and parallel slats, discontinuous recesses, and connecting braces facilitates industrialization, allowing for easier manufacturing and assembly, with configurations such as accordion or staircase shapes that ensure opacity to solar radiation while allowing vision through recesses, using a planar ribbon that can be molded or stamped.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If blades are made with multiple disjointed surfaces to achieve opacity perpendicular to sun direction, then solar protection performance is improved, but manufacturing complexity increases due to multiplication of parts and high accuracy requirements
Solution Approach 1:
The patent merges multiple disjointed surfaces into a single continuous blade element with a wavy profile. Instead of assembling multiple separate slats to achieve opacity, the invention creates one monolithic blade with undulating surfaces that provide the same solar blocking function, thereby eliminating assembly operations and reducing manufacturing complexity while maintaining optical performance
2Object-affected harmful factors
If multiple parts are assembled to form blades with disjointed surfaces, then opacity in perpendicular direction is improved, but manufacturing precision requirements increase due to need for accurate angular positioning
Solution Approach 1:
The invention combines multiple surfaces into a single molded blade element, eliminating the need for precise angular positioning of separate parts. The wavy profile is created as an integral feature during molding, ensuring consistent orientation and spacing of opaque surfaces without requiring post-assembly alignment operations
3Ease of manufacture
If openwork metal sheets are extended to form blades, then manufacturing simplicity is improved, but aesthetic quality and vision through blade deteriorate due to inability to obtain large elongated slats
Solution Approach 1:
The invention changes the geometric parameters of the blade by introducing a wavy profile with specific amplitude and wavelength characteristics. This transforms a simple extended sheet into an aesthetically pleasing structure with controlled light transmission, maintaining manufacturing simplicity through single-step molding while achieving both visual appeal and functional performance
