Solution Overview

Problem

Existing display devices in portable information processors are prone to breakage due to accidental forces and lack the ability to provide a seamless large screen display.

Innovation Solution

A bendable information processor with a bendable display unit and a bend position sensor that allows the display unit to be divided into regions based on bend position data, enabling seamless large screen display and power-saving functionality.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of stationary object

If a large screen display device is used to provide seamless large screen display, then the display area is increased, but the device becomes more prone to breakage due to accidental forces

Engineering Contradiction:
Improvedisplay areaVSAvoidbreakage resistance
Core Design Contradiction:
Area of stationary objectVSReliability

Solution Approach 1:

The display device is divided into multiple separate display units that can be arranged to form a large screen. Each display unit is individually protected and less susceptible to breakage from accidental forces compared to a single large screen. The segmentation allows the system to maintain large display area while improving reliability through distributed structure.

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If the display unit is bent to enable portability, then the device becomes more portable, but the display functionality is compromised

Engineering Contradiction:
ImproveportabilityVSAvoiddisplay functionality
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The display device incorporates flexible or bendable display units that can dynamically change their configuration. The display units can be bent or folded for portable storage and transport, then restored to their functional configuration for display operation. This dynamic adaptability allows the device to switch between portable and functional states without permanent damage.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The display units utilize flexible display technology that allows bending without breaking. The flexible display structure enables the device to be folded or bent for portability while maintaining display functionality. The flexible nature of the display units allows them to withstand bending stresses that would damage rigid displays.

Inventive Principle:
Principle #30Flexible shells and thin films

3Reliability

If the display unit is divided into regions at bend position to maintain functionality, then the display can adapt to bent configuration, but the seamless large screen display capability is reduced

Engineering Contradiction:
Improvedisplay functionality in bent stateVSAvoidseamless display area
Core Design Contradiction:
ReliabilityVSArea of stationary object

Solution Approach 1:

The display system dynamically adjusts its configuration based on whether the display units are bent or flat. When flat, the units form a seamless large screen. When bent, the units are divided into regions that maintain functionality in the bent configuration. This dynamic reconfiguration allows the system to optimize for either seamless display or portable functionality depending on the state.

Inventive Principle:
Principle #15Dynamics
