Solution Overview

Problem

Existing electronic devices, particularly wearable devices, have displays with a single structure and small size, making them inconvenient for users to operate or watch.

Innovation Solution

An electronic device with a first display and at least two second displays that can move between first and second positions, driven by a transmission assembly, to increase the display size and flexibility.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of moving object

If a single structure display is used in wearable devices, then the device maintains a compact appearance, but the display size is small making it inconvenient for users to operate or watch

Engineering Contradiction:
Improvedisplay sizeVSAvoiddisplay structure
Core Design Contradiction:
Area of moving objectVSDevice complexity

Solution Approach 1:

The display is divided into multiple independent display units (first display and second displays) that can be separately controlled and positioned. This segmentation allows the display area to be expanded by adding more display units without increasing the complexity of a single integrated display structure.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent transitions from a two-dimensional single-display layout to a three-dimensional multi-display configuration where second displays can be positioned at different spatial locations relative to the first display. This dimensional expansion enables larger display area while maintaining compact form factor.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Ease of operation

If multiple second displays are added to increase display area, then the display size is enlarged for better usability, but the device structure becomes more complex

Engineering Contradiction:
ImproveusabilityVSAvoiddisplay structure
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The transmission assembly serves multiple functions: it drives the movement of second displays between different positions, enables the displays to be arranged in various configurations (stacked, side-by-side, or surrounding), and adapts to different display scenarios. This multi-functionality reduces the need for additional separate mechanisms.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The display structure is made dynamic rather than static, with second displays capable of moving between different positions and configurations. This dynamic arrangement allows the display to adapt to different usage scenarios and maintain compact appearance when not in use, reducing perceived structural complexity.

Inventive Principle:
Principle #15Dynamics

3Area of moving object

If second displays are positioned to enclose the first display, then a larger display area is formed, but the transmission mechanism becomes more complex

Engineering Contradiction:
Improvedisplay areaVSAvoidtransmission mechanism
Core Design Contradiction:
Area of moving objectVSDevice complexity

Solution Approach 1:

Multiple transmission assemblies are integrated into a unified system that coordinates the movement of all second displays simultaneously. The control mechanism merges the individual driving functions to achieve coordinated movement, reducing the overall complexity compared to separate independent mechanisms for each display.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

Disclosed is an electronic device, including a first display (10), a transmission assembly (30), and at least two second displays (20). The first display (10) includes a first surface and a second surface opposite to the first surface. The at least two second displays (20) are connected to the transmission assembly (30). The transmission assembly (30) drives the at least two second displays (20) to move between first positions and second positions. When the at least two second displays (20) are located at the first positions, the at least part of each of the least two second displays (20) is covered by an orthographic projection of the first display (10) along a perpendicular direction of the second surface. When the at least two second displays (20) are located at the second positions, the at least two second displays (20) are located on a periphery of the first display (10) and abut against an outer peripheral wall of the first display (10).
