Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for shielding buildings and vehicles from sunlight alter aesthetics, are not adaptable to varying sun ray inclinations, and limit vision and field of view.
Innovation Solution
A sun visor with a laminated glass panel featuring alternating opaque and transparent zones, allowing for adjustable orientation to block direct sunlight while allowing diffuse radiation, thereby reducing the need for artificial lighting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If conventional sunshading techniques (shutters, curtains, opaque panels) are used, then direct sunlight is blocked effectively, but the overall aesthetics of the building or vehicle is altered and vision through the opening is limited
Solution Approach 1:
The panel is segmented into multiple transparent zones and opaque zones arranged in a specific pattern. The opaque zones block direct sunlight while the transparent zones allow vision and diffuse light transmission, resolving the contradiction between sunlight blocking and aesthetics/vision.
Solution Approach 2:
Different zones of the panel have different optical properties - some areas are opaque for sun blocking while others remain transparent for vision. This local differentiation allows the panel to simultaneously achieve sunlight protection and aesthetic/vision requirements that would be compromised by a uniformly opaque solution.
2Object-affected harmful factors
If conventional sunshading techniques are used, then sunlight protection is provided, but the solution is not adaptable to variations in sun ray inclination throughout the day and season
Solution Approach 1:
The panel is made rotatable about an axis to change its orientation angle dynamically. This allows the panel to adapt to varying sun ray inclinations throughout the day and across different seasons, maintaining effective sunlight blocking while allowing diffuse light transmission when the sun is at different positions.
3Object-affected harmful factors
If conventional sunshading techniques are used, then direct sunlight is blocked, but vision and field of view through the opening are limited or prevented
Solution Approach 1:
The panel is divided into transparent zones that allow vision through the opening and opaque zones that block direct sunlight. This segmentation enables users to maintain a clear field of view while still receiving protection from direct solar radiation.
Solution Approach 2:
The panel converts direct solar radiation (harmful for vision and heating) into beneficial diffuse radiation transmission. The opaque zones block direct beams while allowing diffuse light to pass through, providing both sun protection and maintained vision capability.
4Object-affected harmful factors
If opaque panels or shutters are used to block sunlight, then sun protection is achieved, but artificial lighting becomes necessary during the day increasing energy consumption
Solution Approach 1:
The panel transforms harmful direct solar radiation into beneficial diffuse light transmission. By blocking only direct beams while allowing diffuse radiation to pass through the transparent zones, the panel maintains natural lighting in the interior, reducing or eliminating the need for artificial lighting during daytime.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The sun visor effectively blocks direct sunlight without compromising aesthetics or vision, allowing for adaptable shading and reduced energy consumption by utilizing the sun's diffuse radiation.
Implementation Method 1
such a sun visor transmits diffuse radiation originating from solar radiation inside the building or the vehicle
Implementation Method 2
the first and second transparent zones are zones of the panel left bare... the first and second opaque zones are obtained by depositing a layer of an opaque material
