Electronic Device Message Display with Hidden Text Frames

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing electronic devices expose important information transmitted via messages, such as SMS, LMS, and MMS, to external view without adequate protection.

Innovation Solution

Implementing a method and apparatus in electronic devices to generate and transmit messages with hidden text areas using a touch pen, and control display to hide and reveal message text based on user authentication and hiding frame settings.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the entire message text is displayed on the screen, then the user can easily read and check the message content, but the important information in the message is exposed to external view without adequate protection

Engineering Contradiction:

Improvemessage readabilityVSAvoidinformation exposure

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The message display area is segmented into multiple regions: a first message display area that shows hidden text and a second message display area that shows revealed text. This segmentation allows the system to control what information is visible at any given time, protecting sensitive content while maintaining readability when needed.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

A touch-sensitive overlay or cover is introduced as an intermediary element between the user and the message content. This intermediary can be manipulated (e.g., swiped, tapped) to reveal or hide message portions, providing controlled access to information while preventing accidental exposure.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Object-affected harmful factors

If hiding frames are added to the message display area, then the privacy protection is enhanced, but the device complexity increases

Engineering Contradiction:

Improveinformation exposureVSAvoiddisplay structure

Core Design Contradiction:

Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The display structure is designed to serve multiple functions: it displays message content, provides privacy protection through hiding frames, and enables user interaction for revealing content. By integrating these functions into a unified display system rather than adding separate components, the complexity increase is minimized.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The hiding frames and overlay elements are implemented as nested layers within the existing display architecture. The privacy protection layer is embedded within the message display area, allowing both functions to coexist without requiring entirely separate display systems.

Inventive Principle:

Principle #7Nested doll (Nesting)
