Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The complexity in manufacturing insulating glass units with glued-in profiles due to non-parallelism of planes during assembly leads to issues like uneven gluing, pressure distribution challenges, and increased reject rates, especially for multi-chambered units with thin glass sheets.
Innovation Solution
An adaptive insulating glass unit design featuring an additional spacer element that presses the profile to the panes until polymerization, combined with an elastic adhesive sealant to secure the profile and prevent shifting, ensuring uniform pressure and stability, and using absorbent elements to manage moisture and sealants for enhanced fitting and sealing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If conventional insulating glass units with glued-in profiles are manufactured using press assembly technology, then the glass units can be assembled, but the non-parallelism of planes between outer panes causes complexity in positioning the profile and uneven gluing
Solution Approach 1:
The patent introduces a profile positioning system with mechanical guides and alignment features that act as intermediaries between the non-parallel panes and the profile to be glued. These positioning elements compensate for plane non-parallelism by providing reference surfaces and adjustment mechanisms, enabling accurate profile placement despite manufacturing tolerances in the glass panes themselves.
Solution Approach 2:
The invention employs adjustable positioning fixtures that can adapt to varying degrees of non-parallelism by changing their geometric parameters during the gluing process. The system allows for real-time adjustment of profile position and angle, transforming a rigid manufacturing process into a flexible one that can accommodate dimensional variations in the glass panes.
2Manufacturing precision
If uniform pressure is applied during profile gluing to ensure even bonding, then gluing quality improves, but the complexity of achieving and maintaining uniform pressure increases
Solution Approach 1:
The patent separates the pressure application function from the positioning function by using independent pressure distribution elements such as cushioning strips or distributed support points beneath the profile. This extraction allows uniform pressure to be applied through simple compressible elements rather than requiring a complex multi-degree-of-freedom pressure control system.
Solution Approach 2:
The invention uses compressible or porous pressure distribution materials (such as foam strips or cork) between the profiling tool and the glass profile during gluing. These materials automatically distribute applied pressure uniformly across the contact surface, achieving even bonding without requiring precision pressure control mechanisms.
3Productivity
If multi-chambered glass units with thin glass sheets are assembled on automatic lines in vertical position, then productivity increases, but the ability to insert and glue profiles accurately decreases
Solution Approach 1:
The patent incorporates profile positioning fixtures and alignment guides that are pre-installed on the automatic assembly line before the glass panes are positioned. These fixtures establish reference positions and maintain geometric relationships during the vertical assembly process, enabling accurate profile insertion and gluing to occur automatically as part of the high-speed production line rather than as a separate precision operation.

AI summary
The invention relates generally to the field of construction, and in particular to the use of a glass unit instead of the opening sashes of windows and doors, without using sash profiles into which conventional insulating glass units or insulating glass units with one protruding outer pane are usually fixed. The adaptive insulating glass unit is intended for use on windows and doors pre-installed in an opening or facade, as well as for use in the production of new windows and doors, which in turn are used for glazing door and window openings (fixed glazing or one with a sash opening inward, sideways, outward or upward off the frame) in residential buildings, in public and industrial buildings, display structures. The technical result of the invention is a quicker and more accurate assembly of multi-chambered insulating glass units with glued-in profiles, increased light transmission, thermal insulation and soundproofing properties of existing window and door systems without the need to reconfigure production processes, without the need to readjust and replace equipment used in the production of windows, as well as increased light transmission, thermal insulation and soundproofing properties of window and door systems pre-installed in the openings and facades of buildings without the need to reinstall them. The adaptive insulating glass unit designed to be used instead of the opening sashes of windows and doors, without the use of sash profiles into which conventional insulating glass units or insulating glass units with one protruding outer pane are usually fixed, offers new prospects for the design of new window and door systems. The adaptive insulating glass unit contains two outer panes and at least one inner pane, spaced from each other by spacer frames placed between the panes. Moreover, the outer panes are always larger than the inner ones, and between them there is a profile inserted all the way to all the inner panes and simultaneously to one of the outer panes and glued to said outer pane by means of hard glue with additional fixation of the glued profile to another outer pane through the aid of a spacer element, with the gap formed between the profile and the outer pane to which the profile is not glued by means of hard glue filled with elastic glue and sealant, with the outer part of the profile adapted to fixing fittings and seals, which adapt the adaptive insulating glass unit to specific window systems.
