Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices face challenges in preventing deformation of supporting bars, which can lead to instability and damage when the display module is extended or reduced.
Innovation Solution
The display device incorporates a supporting plate with guide grooves, a main case, a moving case, and elastic members. The elastic members are coupled to the supporting plate and guide grooves, applying elastic force to prevent deformation of the supporting bars as the display module changes mode.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the display module is extended or reduced, then the adaptability and versatility of the display device is improved, but the supporting bars may deform leading to instability
Solution Approach 1:
The elastic member is pre-installed between the supporting plate and the moving case to provide preliminary elastic force. This preliminary action prevents deformation of the supporting bars before it occurs during extension or reduction of the display module, ensuring stability is maintained across different display modes.
Solution Approach 2:
The elastic member changes its elastic force parameters dynamically as the moving case moves relative to the main case. When the overlapping area changes during extension/reduction, the elastic member adjusts the magnitude of elastic force applied to the supporting plate, maintaining optimal support conditions across different display configurations.
2Area of moving object
If the moving case moves to extend the display module, then the area of the display module is increased, but the elastic member becomes stretched and requires force management
Solution Approach 1:
The elastic member acts as a counterbalancing force mechanism. When the moving case moves to extend the display module area, the elastic member stretches and generates elastic force that counteracts the mechanical stresses on the supporting bars, balancing the forces during the extension process and preventing structural damage.
3Reliability
If the elastic member is stretched to apply elastic force, then the reliability of the supporting plate is improved, but the device complexity increases
Solution Approach 1:
The elastic member is a self-regulating component that automatically adjusts its elastic force based on its own deformation. As the moving case moves and the elastic member stretches or compresses, it self-adjusts the force applied to the supporting plate without requiring external control systems, sensors, or complex mechanisms, thereby maintaining reliability while minimizing added complexity.

AI summary
A display device includes a display module, a supporting plate disposed under the display module, and including a plate and a plurality of supporting bars arranged in a first direction along with the plate, and extending in a second direction crossing the first direction, a main case disposed under the supporting plate, a moving case which is disposed between the supporting plate and the main case, and which moves in the first direction with respect to the main case, and an elastic member disposed on an upper surface of the moving case, and coupled to the supporting plate. In a state in which the overlapping area of the moving case and the main case is at its minimum, the elastic member is stretched and applies elastic force to the supporting plate.
