Slim Double-Skin Window Structure with Integrated Awning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing double-skin windows and doors structures are bulky, complex, and expensive, with limitations in reducing the width of the air cavity layer, leading to increased damage and maintenance needs, especially in high-rise buildings and high wind pressures, where additional structural elements are required for safety.
Innovation Solution
A slim double-skin structure integrating a glass fixing frame and awning, with a case-type glass fixing frame that reduces the hollow layer width by fixing the outer glass and guiding the awning film, eliminating the need for separate rail structures and enhancing wind pressure resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of stationary object
If the width of the hollow layer is reduced to within 200 to 300 mm to lighten the structure, then the structure becomes lighter and more compact, but the awning in the hollow layer is subject to increased damage and maintenance needs when external wind pressure is high
Solution Approach 1:
The patent merges the glass fixing frame and awning into an integrated structure. The glass fixing frame includes a rail component that simultaneously serves to fix the glass and support the awning, eliminating the need for separate structural elements. This integration strengthens the awning's resistance to wind pressure while maintaining a compact hollow layer width of 200-300mm.
2Reliability
If the awning thickness is increased to secure structural safety in high wind pressure, then the awning becomes more durable, but the overall structure becomes thicker and more complex
Solution Approach 1:
The glass fixing frame is designed with multi-functionality, serving both to secure the glass and to provide structural support for the awning. The rail component within the glass fixing frame acts as both a fixing element and a support structure, allowing the awning to achieve sufficient structural safety without increasing its thickness.
3Stability of the object's composition
If a separate rail structure is added to fix the awning, then the awning stability is improved, but the device complexity and cost increase
Solution Approach 1:
The patent combines the glass fixing frame and awning support function into a single integrated structure. The glass fixing frame includes an integrated rail component that provides both glass fixation and awning support, eliminating the need for separate rail structures and reducing overall device complexity while maintaining awning stability.
