Solution Overview

Problem

Handheld touch screen devices face challenges with imprecise physical interaction and limited viewing capacity due to their small size, and the rigid nature of standard displays hinders portability and efficient energy utilization, necessitating a foldable design that can adjust size and harness mechanical energy for power generation.

Innovation Solution

A foldable touch screen display device with flexible or tiled segments that can fold from a compact to an expanded state, incorporating a power generation system that converts hinge force into electrical energy to recharge batteries, featuring a central hinge mechanism with integrated power generators, ratchets, and flywheels to optimize energy translation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of moving object

If the display size is increased to improve viewing capacity and interaction precision, then the device becomes less portable and more rigid

Engineering Contradiction:
Improvedisplay areaVSAvoidportability
Core Design Contradiction:
Area of moving objectVSEase of operation

Solution Approach 1:

The display device employs a flexible form factor that allows it to dynamically change between folded and unfolded states. When folded, the device achieves compact portability; when unfolded, it provides a larger display area for improved viewing and interaction. This dynamic transformation resolves the contradiction between display size and portability.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The display is segmented into multiple flexible segments that can be folded relative to each other. This segmentation allows the device to be folded into a compact form for portability while maintaining a large total display area when unfolded, effectively resolving the contradiction between size and portability.

Inventive Principle:
Principle #1Segmentation

2Ease of operation

If a hinge mechanism is added to enable folding, then portability is improved, but mechanical energy is consumed without utilization

Engineering Contradiction:
ImproveportabilityVSAvoidmechanical energy
Core Design Contradiction:
Ease of operationVSLoss of energy

Solution Approach 1:

The hinge mechanism's mechanical energy, which would otherwise be lost during folding operations, is converted into a beneficial resource by integrating a power generation system. The mechanical motion of folding and unfolding the device generates electrical energy that charges the battery, transforming energy loss into energy gain.

Inventive Principle:
Principle #22Blessing in disguise (Convert harm into benefit)

Solution Approach 2:

The device charges its own battery through the mechanical action of folding and unfolding. The power generation system integrated into the hinge mechanism converts the user's natural folding motion into electrical energy, allowing the device to self-charge without requiring external power sources.

Inventive Principle:
Principle #25Self-service

3Stability of the object's composition

If the display is made rigid for structural stability, then manufacturing is simplified, but portability and flexibility are reduced

Engineering Contradiction:
Improvestructural stabilityVSAvoidflexibility
Core Design Contradiction:
Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The display employs flexible display technology that maintains structural integrity while enabling folding. The flexible display segments can be bent and folded without compromising their structural stability, allowing the device to adapt between compact and expanded states while maintaining display quality and structural soundness.

Inventive Principle:
Principle #30Flexible shells and thin films

AI summary

A foldable touch screen display device made up of flexible or tiled display segments that can be folded from a compact state to an expanded state which also includes a power generation system. The form factor of the compact state is roughly the size of a typical handheld phone or smaller. The form factor of the expanded state is roughly the size of a larger phone or tablet computer, which may also include the mechanical functionality of a laptop. The device form factor may also be a flip phone configuration. Both folded states may include an integrated speaker and microphone. The power generation system utilizes the force applied to the hinge of the device to ultimately recharge the batteries embedded within the device. The device may further include sensors to indicate the position of each display segment. In one embodiment, a module attached to, situated within, or otherwise associated with at least one segment of the flexible display or rigid display may contain all or substantially all processing and memory, along with a communications system, which may be used in any folded state.
