Sliding Window Glass Fixing Bracket Insulation Structure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing installation structures for glass fixing gaskets and window glass panel fixing brackets in sliding window systems face challenges in providing both effective wind pressure resistance and maximum insulation performance, as EPDM synthetic rubber materials used for sealing and fixing functions result in high heat loss and dew condensation, while foam rubber materials offer improved insulation but compromise structural stability under strong wind pressure.
Innovation Solution
An installation structure featuring an insulating glass pedestal made of expanded plastic-based material with an outer glass fixing gasket and window glass panel fixing bracket made of expanded rubber and plastic-based materials, respectively, providing a sealing and insulation function while maintaining structural stability through a wedge method and reduced cross-section design for enhanced wind pressure resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If EPDM synthetic rubber is used for glass fixing gasket and window glass panel fixing bracket, then air tightness and structural fixing force strength are sufficiently provided, but heat loss is large and thermal insulation performance is limited
Solution Approach 1:
The patent divides the original single-material fixing system into two separate components: a glass fixing gasket made of EPDM synthetic rubber for sealing and fixing, and a window glass panel fixing bracket made of foam rubber material for insulation. This segmentation allows each component to specialize in its primary function while avoiding the energy loss associated with using EPDM for both sealing and structural support.
Solution Approach 2:
The foam rubber fixing bracket acts as an intermediary component between the EPDM gasket and the window frame. It provides thermal insulation while the EPDM gasket maintains the sealing function. The intermediary bracket reduces heat transfer from the window glass panel to the frame, thereby reducing overall heat loss.
2Loss of energy
If foam rubber material is used for glass fixing gasket, then energy efficiency is improved and condensation is prevented, but structural stability under strong wind pressure is compromised
Solution Approach 1:
The patent segments the functional responsibilities: the foam rubber material is used specifically for the fixing bracket that provides insulation, while the EPDM synthetic rubber is used for the gasket that provides sealing and wind pressure resistance. This segmentation allows foam rubber to provide insulation without compromising structural stability, as the EPDM gasket handles the structural loading.
Solution Approach 2:
Different materials are assigned to different locations based on their specific properties: EPDM synthetic rubber is placed at the sealing interface where elasticity and wind pressure resistance are needed, while foam rubber material is placed in the fixing bracket where thermal insulation is the primary requirement. This local quality assignment optimizes performance in each specific location.

AI summary
The present invention relates to an installation structure of a glass fixing gasket and a window glass panel fixing bracket, which fixes a window glass panel of a fixed window included in a sliding window system which comprises a segmented window frame and, more specifically, to an installation structure of a glass fixing gasket and a window glass panel fixing bracket, wherein the glass fixing gasket and the window glass panel fixing bracket are installed between a window frame portion which supports three sides (an upper surface, a lower surface, and one external side surface that is not a middle bar side surface) of a fixed window included in a sliding window and a window glass panel provided as a double-pane, in order to provide a sealing function for preventing ventilation and a function of stably fixing the window glass panel against high wind pressure (wind pressure resistance), and moreover, to ensure maximum heat insulation performance.
