Solution Overview

Problem

Existing transparent display apparatuses do not effectively utilize transparency to provide information in various environments, particularly in transportation settings, where users need to be aware of potential collision hazards while maintaining visibility of the background.

Innovation Solution

A transparent display apparatus equipped with a communication unit to receive surrounding situation information, a controller to determine danger elements, and a location detector to adjust the display of information based on the user's field of view, displaying critical information about hidden collision hazards on the transparent display.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Illumination intensity

If a transparent display apparatus is used to display information, then visibility of background is maintained, but information about hidden danger elements cannot be effectively provided

Engineering Contradiction:
ImprovetransparencyVSAvoidinformation about hidden danger elements
Core Design Contradiction:
Illumination intensityVSLoss of information

Solution Approach 1:

The system performs preliminary detection of surrounding objects using sensors before they become visible threats. The controller pre-identifies potential danger elements by analyzing sensor data, object positions, and movement trajectories, then displays warning information about these hidden dangers on the transparent display before the user would naturally detect them, thus preventing information loss while maintaining transparency.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The transparent display apparatus acts as an intermediary between the hidden danger elements (detected by sensors) and the user. The controller processes sensor data and generates visual representations of hidden dangers, which are then displayed on the transparent display panel. This intermediary function allows the system to convey information about invisible threats without compromising the transparency of the display.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Loss of information

If the transparent display displays information about danger elements, then user awareness of hidden hazards is improved, but the transparency and background visibility may be compromised

Engineering Contradiction:
Improveinformation about danger elementsVSAvoidtransparency
Core Design Contradiction:
Loss of informationVSIllumination intensity

Solution Approach 1:

The system applies local quality by displaying danger element information only in specific regions of the transparent display corresponding to the actual locations of detected objects. Rather than making the entire display opaque, the controller selectively activates display regions where danger elements are detected, maintaining transparency in all other areas. This allows localized information presentation while preserving overall background visibility.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The system uses color changes to encode different levels of danger and object types on the transparent display. Different colors represent different categories of hazards (e.g., red for high danger, yellow for medium danger), allowing the user to quickly comprehend the nature and urgency of hidden threats without requiring large or opaque display elements. This color-coding system conveys rich information while maintaining display transparency.

Inventive Principle:
Principle #32Color changes

3Reliability

If surrounding situation information is processed to identify danger elements, then collision prevention capability is improved, but device complexity increases

Engineering Contradiction:
Improvecollision prevention capabilityVSAvoidprocessing system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The controller performs multiple functions using a single integrated processing unit: it detects surrounding objects, tracks their movements, determines danger levels, calculates collision risks, and generates display information. This multi-functional approach consolidates what could be separate complex subsystems into one controller, improving reliability through comprehensive processing while managing complexity through functional integration rather than physical multiplication of components.

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

A transparent display apparatus which is used in a transportation apparatus includes: a communication unit which receives surrounding situation information, a controller which recognizes surrounding objects using the surrounding situation information, and determines a danger element that is likely to collide with the transportation apparatus using characteristics of the surrounding objects and a movement characteristic of the transportation apparatus, and a transparent display which displays information for informing a user of the danger element. Accordingly, a surrounding situation can be effectively presented.
