Glazing Insert Stopper for Consistent Gasket Filling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing manufacturing process for glazing with profiled joint portions and inserts having hollows faces instability due to difficulties in filling the hollows with gasket material, leading to inconsistent filling, adherence issues, and unreliable positioning, resulting in a lack of repeatability and mechanical strength in the glazing assembly.
Innovation Solution
Incorporating a stopper at the ends of the insert to prevent gasket material from penetrating into the hollows, ensuring consistent filling and a smooth surface, while using an adhesive coating for secure positioning, and employing various stopper designs such as caps or integral parts to effectively block the ends.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the hollow of the insert is filled with gasket material during injection, then the mechanical strength of the glazing assembly is improved, but the manufacturing process stability deteriorates due to difficult-to-control filling parameters
Solution Approach 1:
The invention extracts the harmful hollow cavity from the insert structure by filling it with a stopper material before the glazing manufacturing process. This eliminates the filling control problems while maintaining the structural integrity and strength benefits that would otherwise require gasket material filling.
Solution Approach 2:
The hollow of the insert is pre-filled with stopper material before the injection molding process begins. This preliminary action prevents the gasket material from entering the hollow cavity during injection, ensuring consistent filling parameters and manufacturing stability while still allowing the gasket material to provide mechanical strength at the critical joint interface.
2Strength
If the hollow of the insert is filled with gasket material, then adhesion between materials is improved, but the surface quality of the profiled joint portion deteriorates with wrinkles and bubbles
Solution Approach 1:
The invention removes the hollow cavity that causes surface defects by filling it with stopper material. This prevents gasket material from being trapped in the hollow during injection, eliminating wrinkles and bubbles on the profiled joint portion surface while maintaining adequate adhesion at the critical bonding interfaces.
3Reliability
If holes are provided in the insert for positioning, then the positioning reliability is improved, but the positioning accuracy deteriorates when gasket material enters the hollow and modifies insert position
Solution Approach 1:
The invention extracts the problematic hollow space that allows gasket material to enter and displace the insert. By pre-filling the hollow with stopper material, the insert maintains its positioned accuracy throughout the injection process, while the positioning holes remain functional for initial insert placement in the mold.
