Solution Overview
Problem
Conventional double-skin window systems increase construction costs and require complex maintenance due to the installation of window shades or blinds, which also lead to inefficient energy use when operated manually or out of season.
Innovation Solution
A window system with a slim structure that blocks solar radiation by using an outer glass with high absorption rates to convert light into heat, which is then blocked by an inner glass with high heat-insulating performance, eliminating the need for window shades or blinds and maintaining indoor illumination while reducing solar radiation heat gain by 30% or more.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a window shade or blind is installed in the hollow layer to control solar heat, then solar radiation protection is improved, but the thickness of the double-skin window increases and construction cost increases more than twice compared to single-skin window system
Solution Approach 1:
The invention extracts and eliminates the window shade or blind from the hollow layer, replacing it with a selective glass configuration. The outer glass layer with high solar absorption coefficient absorbs solar radiation, converting it to heat that is then blocked by the inner glass layer, achieving solar protection without the need for additional shading devices that would increase thickness.
Solution Approach 2:
The invention changes the optical parameters of the glass layers, specifically using an outer glass with high solar absorption coefficient and an inner glass with high heat insulating performance. This parameter change allows the system to block solar radiation heat while maintaining a slim structure without requiring thick shading components.
2Object-affected harmful factors
If a window shade or blind is installed in the hollow layer to control solar heat, then solar radiation protection is improved, but maintenance of the window shade or blind becomes difficult as it is installed inside the hollow layer
Solution Approach 1:
The invention removes the window shade or blind from the hollow layer entirely, eliminating the maintenance difficulty associated with accessing and servicing components installed inside the hollow layer. The solar protection function is transferred to the glass layers themselves, which are inherently maintenance-free.
3Object-affected harmful factors
If a separate apparatus with power-driven device is used to operate window shade or blind in accordance with season, then solar radiation control is improved, but device complexity and energy consumption increase
Solution Approach 1:
The invention extracts and eliminates the separate power-driven apparatus for operating window shades or blinds. The solar radiation control function is integrated into the glass layers themselves, which passively absorb and block heat without requiring any mechanical devices, power consumption, or complex control systems.
Solution Approach 2:
The glass layers perform the solar radiation control function autonomously without requiring external power or control systems. The outer glass automatically absorbs solar radiation and converts it to heat, and the inner glass automatically blocks this heat, providing self-service solar protection without complex apparatus.
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 solution provides effective solar radiation blocking without increasing the window system's thickness or construction costs, maintaining indoor illumination, and reducing the need for maintenance, thus improving energy efficiency and comfort.
Implementation Method 1
light is converted into heat by an outer glass having a high absorption rate
Implementation Method 2
the heat is blocked by an inner glass having a high heat insulating performance
Implementation Method 3
since the hollow layer has a structure able to be naturally ventilated, it is possible to discharge the heat of the hollow layer due to the solar radiation to the outside

AI summary
A window system according to an aspect of the invention includes: a window frame; an inner window installed at an indoor side of the window frame; an outer window fixed to the window frame and spaced apart from the inner window with a predetermined distance at an outdoor side to form a hollow layer between the outer window and the inner window; an air-flowing opening formed between the outer window and the window frame to form a flow path in which air in the hollow layer flows or circulates; and an opening and closing device provided at one side of the inner window to open and close the inner window from the window frame. The outer window may include a tinted glass or a glass having a high absorption rate and a bracket for fixing the tinted glass to the window frame.
