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

VSEngineering 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

Engineering Contradiction:
Improvetouch control functionalityVSAvoidinstallation complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

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.

Inventive Principle:
Principle #1Segmentation

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.

Inventive Principle:
Principle #30Flexible shells and thin films

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

Engineering Contradiction:
Improveimage qualityVSAvoidfilm protection
Core Design Contradiction:
Manufacturing precisionVSReliability

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.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

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).
