Insulating glazing unit with projection and input means
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing insulation glazing units in display windows, particularly in colder climates, face challenges in incorporating touch control mechanisms due to their thickness and the bulkiness required for installing LCD panels, making it difficult to provide touch-controlled displays effectively.
Innovation Solution
An insulation glazing unit with an interactive film and a projection film attached to opposing surfaces of two or more panes, forming an intermediate space, allowing touch control through one pane and optimizing the distance between the films for improved image quality and functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If an LCD panel is installed behind a thick insulation glazing unit for touch control, then touch control functionality is achieved, but the installation becomes bulky and complex
Solution Approach 1:
The display system is segmented into two separate films (interactive film and projection film) that can be independently attached to different panes of the insulation glazing unit. This segmentation allows each film to be installed separately through the glass panes without requiring bulky installation equipment, as each thin film can be maneuvered through the glazing thickness independently.
Solution Approach 2:
The patent replaces the rigid LCD panel with flexible thin films (interactive film and projection film) that can be easily maneuvered through the insulation glazing unit. These thin films eliminate the bulkiness associated with traditional LCD panels while maintaining touch control functionality, as they can be attached to the inner surfaces of the glass panes from the outside.
2Manufacturing precision
If the distance between interactive film and projection film is reduced for better image quality, then image quality improves, but the films become more vulnerable to damage
Solution Approach 1:
The patent positions the interactive film and projection film on opposite sides of the insulation glazing unit, utilizing the thickness dimension of the glazing as a protective barrier. This spatial arrangement in three-dimensional space allows the films to be close enough for good image quality while the glass panes provide physical protection against environmental damage and handling issues.

AI summary
A window element (1) for controlling information reflected or projected to a surface of the window element by means of an interactive film (5) attached to the window element comprises at least two panes (6, 7, 13) forming an intermediate space between the at least two panes (6, 7, 13). The interactive film (5) is disposed in the intermediate space (15) and attached to a first pane (6) of the at least two panes, and the controlling is implementable by touch through the first pane (6). The window element further comprises a projection film (11) for displaying the information reflected or projected thereon, which projection film (11) is disposed in the intermediate space (15) between the at least two panes (6, 7, 13).
