Solution Overview

Problem

Existing electronic devices face challenges in balancing screen size for viewing experience and portability, as their dimensions are often dictated by the display screen, limiting flexibility and convenience.

Innovation Solution

A foldable electronic device design featuring a pivotally connected foldable display module and input module, allowing the device to open and close, with components that can move relative to each other, reducing overall size for portability while maintaining larger dimensions for use.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of stationary object

If the display screen dimensions are increased to enhance viewing experience, then the screen size is improved, but the device dimensions and portability deteriorate

Engineering Contradiction:
Improvedisplay screen areaVSAvoiddevice dimensions
Core Design Contradiction:
Area of stationary objectVSLength of moving object

Solution Approach 1:

The device is divided into multiple separable components including a display module, input module, and connector portions that can be detached and reattached. This segmentation allows the display screen area to be large when needed while the device can be disassembled into smaller portable segments when portability is required

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The connector includes movable portions that enable the display module and input module to dynamically change their relative positions and orientations. The connector can transition between connected and disconnected states, and allow rotational movement, enabling the device to adapt between large-screen configuration and compact portable configuration

Inventive Principle:
Principle #15Dynamics

2Length of moving object

If the device is made compact for portability, then device dimensions are reduced, but the display screen area and viewing experience deteriorate

Engineering Contradiction:
Improvedevice dimensionsVSAvoiddisplay screen area
Core Design Contradiction:
Length of moving objectVSArea of stationary object

Solution Approach 1:

The display module can be positioned to overlap with the input module when connected, creating a nested arrangement that reduces the overall device footprint. The flexible connector allows the display module to be folded back or positioned compactly while remaining functional, enabling portable carrying without permanently reducing display area

Inventive Principle:
Principle #7Nested doll (Nesting)

3Adaptability or versatility

If the device structure is made flexible and foldable, then portability is improved, but structural stability and reliability deteriorate

Engineering Contradiction:
Improvefoldable configurationVSAvoidstructural stability
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The connector includes cushioning elements and flexible portions that are pre-designed to absorb mechanical stress and protect the connection between display module and input module during folding and unfolding operations. This beforehand cushioning prevents damage to the structural integrity while enabling flexible configurations

Inventive Principle:
Principle #11Beforehand cushioning (Prior cushioning)

Solution Approach 2:

The connector incorporates flexible circuit boards, flexible cables, and elastomeric materials that maintain electrical and mechanical connections while accommodating folding and bending. These flexible components preserve structural reliability through repeated flexing cycles while enabling the adaptability of foldable configurations

Inventive Principle:
Principle #30Flexible shells and thin films
