Problem

Existing dimming glasses lack the ability to conveniently adjust light transmittance and integrate display functionality, limiting their applicability and user experience.

Innovation Solution

An intelligent glass system incorporating a touch display assembly and glass assembly, where the touch display assembly sends dimming instructions to adjust the glass assembly's light transmittance, featuring a transparent touch display and electroluminescent devices for display and touch functionality, with controllers communicating via a CAN bus or RS485 module to manage light transmittance adjustments.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If traditional dimming glass is used, then light transmittance control is achieved, but display functionality and user interaction capability are lacking

Engineering Contradiction:

Improvefunctionality integrationVSAvoidsystem structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent combines the dimming glass function with a transparent touch display into a single integrated unit. The touch display assembly is positioned between the liquid crystal layer and the outer glass substrate, allowing the glass to simultaneously serve as both a dimming element and a display interface, thereby improving versatility without proportionally increasing complexity

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The intelligent glass is designed to perform multiple functions: light transmittance control through liquid crystal switching, visual information display through the transparent OLED screen, and touch input reception through the transparent touch panel. This multi-functional design allows a single component to replace what would traditionally require separate systems

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Ease of operation

If a touch display assembly is integrated into the glass, then user interaction and display capability are improved, but manufacturing complexity increases

Engineering Contradiction:

Improveuser interactionVSAvoidassembly process

Core Design Contradiction:

Ease of operationVSEase of manufacture

Solution Approach 1:

The touch display assembly is divided into distinct functional layers: transparent OLED display layer, transparent touch-sensitive layer, and connection interface layer. Each layer can be manufactured and tested independently before final assembly with the dimming glass, simplifying the overall manufacturing process while maintaining ease of operation

Inventive Principle:

Principle #1Segmentation

3Adaptability or versatility

If multiple functional layers are stacked in the glass, then versatility is enhanced, but manufacturing precision requirements increase

Engineering Contradiction:

Improvefunctional integrationVSAvoidlayer alignment

Core Design Contradiction:

Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The transparent touch display and control assembly are nested within the sandwich structure of the intelligent glass, positioned between the liquid crystal layer and the outer glass substrate. This nested configuration allows multiple functional layers to be integrated while maintaining the structural integrity of the glass and reducing the precision requirements for layer alignment compared to surface-mounted configurations

Inventive Principle:

Principle #7Nested doll (Nesting)
