Solution Overview

Problem

Conventional train windows have a single function for observation and cannot accommodate additional facilities, resulting in wasted space and limited passenger comfort.

Innovation Solution

A train window structure incorporating a hollow design with a light-emitting panel, preferably an OLED panel, integrated into the window frame, allowing for information display and enhanced functionality while maintaining transparency in the absence of signals.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a conventional train window is used for observation only, then the window structure is simple, but the window area is wasted and additional facilities cannot be arranged

Engineering Contradiction:

Improvewindow functionalityVSAvoidwindow structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The train window is transformed from a single-function observation structure to a multi-functional system that simultaneously provides observation, information display, and advertising capabilities. The display screen is integrated into the window glass, allowing the window to serve multiple purposes without occupying additional space, thereby resolving the contradiction between versatility and complexity.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The display screen and advertising module are merged with the window glass structure itself, rather than being separate components. This integration allows the window to function as both an observation portal and an information display medium, combining multiple functions into a unified structure that reduces overall system complexity while enhancing adaptability.

Inventive Principle:

Principle #5Merging (Combining)

2Loss of information

If a display is added to the train window, then information can be provided to passengers, but the window structure becomes more complex

Engineering Contradiction:

Improveinformation deliveryVSAvoidwindow structure

Core Design Contradiction:

Loss of informationVSDevice complexity

Solution Approach 1:

The display screen is merged directly with the window glass, eliminating the need for separate display housings and mounting structures. This integration reduces structural complexity while effectively delivering information to passengers, as the display becomes an inherent part of the window rather than an add-on component.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The window structure is designed to universally serve both observation and information display functions through the integrated screen. This multi-functionality approach allows a single structure to fulfill multiple roles, reducing the need for additional components and simplifying the overall system while improving information delivery capability.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Productivity

If facilities are arranged at the window, then space utilization is improved, but the window area is reduced

Engineering Contradiction:

Improvespace utilizationVSAvoidwindow area

Core Design Contradiction:

ProductivityVSArea of stationary object

Solution Approach 1:

The display and advertising facilities are merged with the window glass itself, allowing these functional elements to occupy the same space as the observation area rather than encroaching on it. This integration maintains the full window area for viewing while simultaneously providing information display and advertising functions, thus improving space utilization without reducing visible area.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The window is designed as a multi-functional element that simultaneously serves as an observation portal, information display, and advertising medium. By making the window itself capable of multiple functions, the design maximizes space utilization without sacrificing window area, as all functions are embodied within the same structural footprint.

Inventive Principle:

Principle #6Universality (Multi-functionality)
