Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If additional software is used for decryption, then secret visual information can be decrypted, but the decryption process becomes more complicated and inconvenient

Engineering Contradiction:

Improvedecryption capabilityVSAvoiddecryption process complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The display device performs decryption operations autonomously using its own display structure (alternating light emitting and transparent regions with reflection element) without requiring external software assistance. The device serves itself by utilizing its physical characteristics to automatically combine sharing images and reveal secret information directly on the display screen.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent replaces the software-based decryption system with a hardware-based optical system. The display device uses its physical structure (light emitting regions, transparent regions, and reflection element) to perform decryption through optical reflection and image combination, eliminating the need for software processing.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Reliability

If additional software is used for decryption, then secret visual information can be decrypted, but the decryption process becomes more inconvenient

Engineering Contradiction:

Improvedecryption capabilityVSAvoiddecryption operation convenience

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The display device autonomously performs decryption without user intervention in the software process. Users simply need to display sharing images on the device, and the system automatically combines them through its optical structure to reveal secret information, making the operation as convenient as displaying any other image.

Inventive Principle:

Principle #25Self-service

3Reliability

If sharing images are displayed separately, then security is maintained, but the secret information remains hidden and requires decryption

Engineering Contradiction:

Improveinformation securityVSAvoidaccessibility of secret information

Core Design Contradiction:

ReliabilityVSLoss of information

Solution Approach 1:

The secret information is divided into multiple sharing images that are displayed in different regions (light emitting and transparent regions) of the display device. Each sharing image alone appears meaningless or unclear, maintaining security, but when combined through the reflection element, the complete secret information is revealed.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The reflection element acts as an intermediary that facilitates the combination of sharing images from different regions. It reflects light from the transparent region to overlay the second sharing image with the first sharing image in the light emitting region, enabling secret information to be reconstructed without direct software intervention.

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

A display device having a plurality of light emitting regions and a plurality of transparent regions alternately disposed is provided. The display device includes a display module and a reflection element. The display module includes a front pixel and a rear pixel disposed opposite to the front pixel, the front pixel and the rear pixel are disposed in the plurality of light emitting regions, and the front pixel displays a first image in the plurality of light emitting regions. The reflection element is disposed at a side of the display module adjacent to the rear pixel, wherein the reflection element reflects a second image displayed by the rear pixel to form a third image. The first image in the plurality of light emitting regions and the third image in the plurality of transparent regions are combined to show a predetermined image.
