Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solar shading systems are inefficient in preventing direct sunlight year-round, often requiring mechanical adjustments, wasting materials, and obscuring external views, while also being costly and difficult to maintain.
Innovation Solution
A solar shading panel comprising a frame and opaque panel with hollow cylinders that allow natural light and provide exterior views, with the upper part of the cylinder designed to protect against direct sunlight and the lower part to reflect indirect sunlight, optimized for specific latitudes and orientations to prevent direct light without mechanical adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If traditional horizontal or vertical shading panels are used to block direct sunlight, then direct radiation protection is improved, but external views are obscured and material waste increases due to overlapping requirements
Solution Approach 1:
The patent applies cylindrical forms instead of traditional flat panels. The curved surface of the cylinders allows sunlight to be reflected away from the building while maintaining transparency and viewability. The cylindrical geometry naturally directs light without requiring overlapping panels, thus reducing material waste while effectively blocking direct radiation.
Solution Approach 2:
The invention transitions from two-dimensional flat panels to three-dimensional cylindrical elements. This dimensional change enables the shading device to manipulate light through curvature and depth, allowing sunlight to be reflected at specific angles while maintaining visual transparency. The cylindrical form adds a spatial dimension that traditional flat panels cannot achieve.
2Loss of information
If opaque panels with holes or perforates are used to allow external views, then viewability is improved, but direct sunlight protection efficiency decreases
Solution Approach 1:
The cylindrical shape provides curved surfaces that reflect sunlight away from the building interior. The curvature allows the structure to maintain transparency and viewability while effectively blocking direct solar radiation through reflective geometry rather than opaque materials.
Solution Approach 2:
The patent utilizes reflective properties of the cylindrical surfaces to manipulate light behavior. The surfaces are designed to reflect specific angles of sunlight while allowing other light to pass through, creating a dynamic interaction between light, material, and geometry that maintains both viewability and protection efficiency.
3Object-affected harmful factors
If shading panels are angled to protect against direct sunlight, then radiation protection is improved, but device complexity and maintenance costs increase due to mechanical adjustment requirements
Solution Approach 1:
Instead of using adjustable panels that change angle to block sunlight, the invention inverts the approach by using fixed cylindrical elements whose curved geometry inherently directs sunlight away from the building. The passive geometric design eliminates the need for active mechanical adjustment mechanisms.
Solution Approach 2:
The cylindrical shading elements are designed to automatically perform their shading function through their fixed geometric form. The curvature of the cylinders naturally reflects sunlight at appropriate angles without requiring external control systems, mechanical adjustments, or energy input, making the system self-regulating and maintenance-free.
4Object-affected harmful factors
If electronics equipment is used to adjust shading device angles, then sun protection effectiveness is improved, but investment and maintenance costs increase
Solution Approach 1:
The cylindrical shading devices are designed as passive, fixed structures that automatically provide sun protection through their geometric form. No electronic controls, motors, or power systems are required, eliminating both initial investment costs and ongoing maintenance expenses associated with electronic adjustment mechanisms.
Solution Approach 2:
The invention employs simple, inexpensive cylindrical elements that can be manufactured at low cost using basic materials and construction methods. The fixed geometric design eliminates the need for expensive electronic components, making the system economically viable with minimal investment and maintenance requirements.

AI summary
A solar shading panel for use in north and south sides of a building is described, where the solar shading panel is effective in preventing against direct sunlight partially or throughout the year without angle adjusting equipment, while allowing building occupants to perceive external views at all times. The solar shading panel includes a frame and an opaque panel with spacing perforates attached to hollow cylinders. An upper portion of the hollow cylinders can be configured to protect against direct light and a lower portion of the hollow cylinders can be configured to receive and reflect natural light into the building.
