Solution Overview

Problem

Conventional rear-view mirrors in vehicles can obstruct the driver's view of the front and are not flexible, leading to potential interference with the driving situation, and existing display devices do not efficiently manage power consumption or maintain balance during deformation and movement.

Innovation Solution

A display device with a flexible display that is guided by transparent guide plates, allowing it to deform and move while minimizing resistance and power consumption, and maintaining balance through a stable coupling with a flexible printed circuit board, enabling the display to switch between states to provide unobstructed viewing and display information.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a conventional rear-view mirror is installed at the upper portion of the windshield, then the driver can view the rear situation, but the driver's view of the front is obstructed

Engineering Contradiction:

Improverear situation visibilityVSAvoidfront view obstruction

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent applies a flexible display that can dynamically change its configuration between extended and retracted states. When extended, the display provides rear view information; when retracted, it minimizes obstruction to the front view. This dynamic transformation allows the system to adapt to different viewing needs without permanently blocking the windshield.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The flexible display is positioned in a space that utilizes the vertical and depth dimensions rather than purely horizontal placement. By extending downward and forward from the upper windshield area, the display occupies a three-dimensional space that provides rear view functionality without horizontally blocking the driver's forward视线.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

2Ease of operation

If a flexible display is used to enable deformation and movement, then the display can provide unobstructed viewing, but resistance and load increase during deformation

Engineering Contradiction:

Improveunobstructed viewing capabilityVSAvoidresistance during deformation

Core Design Contradiction:

Ease of operationVSForce

Solution Approach 1:

The patent employs a flexible display constructed with thin-film technology that can bend and deform without requiring significant force. The flexible substrate and thin-film transistor structure allow the display to be rolled or folded with minimal resistance, enabling smooth extension and retraction movements while maintaining image quality throughout the deformation process.

Inventive Principle:

Principle #30Flexible shells and thin films

3Adaptability or versatility

If the flexible display is moved and deformed frequently, then adaptability improves, but power consumption increases and component interference occurs

Engineering Contradiction:

Improvedisplay state switchingVSAvoidpower consumption during movement

Core Design Contradiction:

Adaptability or versatilityVSUse of energy by moving object

Solution Approach 1:

The flexible display operates in periodic cycles, extending only when rear view information is needed and retracting when not needed. This intermittent operation rather than continuous movement reduces cumulative power consumption and mechanical wear. The display switches between static states (extended or retracted) rather than remaining in constant motion.

Inventive Principle:

Principle #19Periodic action

4Adaptability or versatility

If the flexible display slides during movement, then positioning flexibility improves, but balance and coupling stability deteriorate

Engineering Contradiction:

Improvepositioning flexibilityVSAvoidcoupling stability with flexible printed circuit board

Core Design Contradiction:

Adaptability or versatilityVSStability of the object's composition

Solution Approach 1:

The connection between the flexible display and the flexible printed circuit board uses an asymmetric coupling design where the electrical contacts and mechanical attachment points are strategically positioned to maintain balance during movement. The asymmetric arrangement ensures that the center of mass and center of rotation are properly aligned, preventing unwanted sliding or detachment during extension and retraction cycles.

Inventive Principle:

Principle #4Asymmetry

AI summary

A display device for a vehicle includes a main body, a guide, and a flexible display. The flexible display is configured to be inserted between a pair of guide plates of the guide. The pair of guide plates are transparent, and an area of the flexible display positioned between the pair of guide plates is configured to vary. The display device allows a front area of the vehicle to be viewed through the transparent guide plates, and allows a rear area of the vehicle to be disposed on the flexible display. The flexible display is configured to be protected by the pair of guide plates and deformed along the pair of guide plates.
