Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing portable electronic devices with clamshell or slider configurations face bulkiness in the closed position due to multiple device housings, limiting the use of larger display surfaces.

Innovation Solution

A flexible display integrated into a blade assembly that slides around a single device housing, transitioning between extended, retracted, and peek positions, using a translation mechanism to maintain a flat upper portion and prevent crumpling, with actuators like spring or dual-shaft motors for smooth operation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of moving object

If multiple device housings are used (clamshell or slider configuration), then the display surface area can be larger, but the device becomes bulky when closed

Engineering Contradiction:

Improvedisplay surface areaVSAvoiddevice volume when closed

Core Design Contradiction:

Area of moving objectVSVolume of moving object

Solution Approach 1:

The display is segmented into multiple sections that can be independently positioned. The flexible display is divided into a first section and a second section that can be relative moved with respect to each other, allowing the display to extend beyond the device housing when needed while maintaining a compact form factor when retracted.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The display configuration is made dynamic rather than static. The flexible display can transition between multiple states (retracted, extended, partially extended) allowing the device to adapt its display surface area based on user needs while maintaining a consistent compact housing volume.

Inventive Principle:

Principle #15Dynamics

2Adaptability or versatility

If the flexible display slides during operation, then the display can transition between positions, but crumpling and pillowing occur

Engineering Contradiction:

Improvedisplay position flexibilityVSAvoiddisplay integrity

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

A blade assembly is introduced as an intermediary component between the flexible display and the device housing. This blade assembly includes a blade that receives the flexible display and guides its movement, preventing direct contact between the display and housing surfaces that would cause crumpling and pillowing.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The flexible display is encapsulated within a protective blade assembly structure that maintains its flatness during movement. The blade assembly provides a controlled environment for the flexible display to slide without external interference that would cause deformation.

Inventive Principle:

Principle #30Flexible shells and thin films

AI summary

An electronic device includes a flexible display and a device housing that defines a translation surface for the flexible display. A blade assembly is positioned between the flexible display and the translation surface. A rotor is positioned within a curvilinear section of the blade assembly and flexible display. A translation mechanism translates the blade assembly and flexible display between an extended position, a retracted position, and a peek position revealing an image capture device.
