Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In sliding window systems with two-sided supporting frames, existing sealing structures using high-density materials like mohair or elastic gaskets face issues with excessive frictional resistance and adhesion, leading to difficult manual operation and potential detachment of gasket fixing ends due to glass panel thickness changes or deformation over time.
Innovation Solution
An installation structure featuring a glass supporting insulation bracket with a rotating groove and an aluminum rotation fastener, combined with a rubber elastic gasket and a plastic sliding cap, which reduces adhesion and maintains the gasket's fixing end position through the rotating fastener's rigidity and shape uniformity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If high-density mohair is used for sealing between the window frame and moving window, then sealing performance is improved, but frictional resistance increases making manual operation difficult
Solution Approach 1:
The patent uses a composite sealing structure combining mohair (for sealing) with an elastic gasket and plastic sliding cap (for reducing friction). This composite approach maintains the sealing effectiveness of high-density mohair while adding components that reduce frictional resistance during operation.
Solution Approach 2:
The plastic sliding cap acts as an intermediary between the elastic gasket and the aluminum window frame surface. It mediates the contact interface, reducing direct adhesion between rubber and aluminum, thereby lowering frictional resistance while allowing the mohair to maintain sealing contact.
2Reliability
If elastic gasket is used for sealing between glass supporting insulation bracket and window frame, then sealing function is achieved, but strong adhesion causes large resistance to sliding operation
Solution Approach 1:
The plastic sliding cap serves as an intermediary component between the elastic gasket (rubber material) and the aluminum window frame surface. It reduces the strong adhesion that occurs directly between rubber and aluminum, thereby minimizing sliding resistance while preserving the sealing function of the elastic gasket.
Solution Approach 2:
The patent changes the material parameter at the contact interface by introducing a plastic sliding cap. This alters the friction and adhesion characteristics between the sealing components and the window frame, reducing the resistance to sliding operation while maintaining sealing effectiveness.
3Ease of manufacture
If elastic gasket fixing end is fitted directly to glass supporting insulation bracket, then installation is simple, but gasket may detach due to glass panel thickness changes or deformation over time
Solution Approach 1:
The rotation fastener acts as an intermediary component between the glass supporting insulation bracket and the elastic gasket fixing end. It provides a stable mounting interface that compensates for variations in glass panel thickness and deformation, preventing gasket detachment while maintaining installation feasibility.
Solution Approach 2:
The rotation fastener structure anticipates and compensates for future deformation and thickness variations of the glass panel. By providing a rigid, stable fitting groove from the beginning, it cushions against the effects of deformation over time, preventing gasket detachment.
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
This configuration minimizes sliding resistance, ensures reliable sealing, and prevents gasket detachment due to glass panel thickness changes or deformation, enhancing the product's weather resistance and longevity.
Implementation Method 1
due to strong interfacial adhesion in an interfacing surface between the outer elastic end of the rubber elastic gasket 2s2 and the upper surface of the aluminum window frame 1, an inconvenience of large resistance to the sliding opening and closing operation of the movable window could not be eliminated
Implementation Method 2
an elastic gasket 2s2 provided so that a fixing end of the elastic gasket is fitted to the side part of the glass supporting insulation bracket 2b

AI summary
The present invention relates to an installation structure of an elastic gasket attached and installed as a sealing member to a moving window glass supporting insulation bracket in a sliding window having a two-sided supporting frame window chassis, and more specifically, it relates to an installation structure of a sealing member (e.g. an elastic gasket) that is installed to provide a sealing function between a glass supporting insulation bracket that directly supports a glass panel of the moving window from the top or bottom and a window frame provided with a sliding rail, when opening and closing the sliding window having only two-sided supporting frame that support both sides of the glass window constituting the sliding window.
