Solution Overview
Problem
Existing display devices face challenges in maintaining surface quality and flexibility during transitions between inserting and spreading states, leading to potential sagging and degradation of the display surface.
Innovation Solution
Incorporation of an extending module with a fixing pin and elastic body to manage the movement of display assembly regions, ensuring equal or differential distances in transitioning between states, and a coupling part to maintain a flat surface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If the display assembly is extended from inserting state to spreading state, then the display area is increased, but the display surface may sag and surface quality degrades
Solution Approach 1:
The extending module is divided into multiple parts (first part, second part, third part) that can move independently relative to each other. This segmentation allows each part to be controlled separately to maintain surface flatness while achieving overall area expansion. The fixing pin mechanism divides the movement control into discrete segments that can be managed independently.
Solution Approach 2:
The elastic body changes its physical state (compression/expansion) in response to movement, providing dynamic parameter adjustment. The elastic force generated by the compressed elastic body adapts to different extension states, maintaining surface stability across the full range of motion from inserting to spreading state.
2Adaptability or versatility
If the display assembly transitions between states, then flexibility and portability are improved, but surface quality and flatness may be compromised
Solution Approach 1:
The elastic body is positioned in advance to provide cushioning force during state transitions. By pre-positioning the elastic body between the first and second parts, the system prepares the necessary restoring force before actual movement occurs, ensuring surface quality is maintained throughout the transition process.
Solution Approach 2:
The elastic body acts as an intermediary element between the moving parts and the display assembly. It mediates the force transmission during state transitions, absorbing shocks and preventing direct mechanical stress on the display surface, thereby preserving surface quality while enabling flexible movement.
3Stability of the object's composition
If the extending module allows differential movement of parts, then surface flatness is maintained, but the device complexity increases
Solution Approach 1:
The fixing pin is extracted as a separate, simple component that can be independently positioned and removed. This extraction simplifies the overall mechanism by using a basic pin-and-hole connection rather than a complex joint, allowing differential movement while maintaining surface flatness through straightforward mechanical means.
Solution Approach 2:
The elastic body provides self-regulating force without requiring external control mechanisms. It automatically compresses and expands based on the relative positions of the first and second parts, maintaining surface flatness through passive elastic recovery rather than active control systems, thereby reducing overall device complexity.

AI summary
A display device includes a display assembly including a first region and a second region, and an extending module under the first region. The second region is under the first region in an inserting state, and a portion thereof is on a same plane as the first region in a spreading state. The extending module includes a first part coupled to an end of the second region, a second part at a side of the first part, a fixing pin including a body part passing through the first part or the second part, and a head part at an end of the body part, and an elastic body interposed between the first part or the second part, and the head part. A moving distance of the first part is substantially equal to a moving distance of the second part when changing from the inserting state to the spreading state.
