Solution Overview
Problem
Conventional display devices lack a robust mechanism to support and expand their display modules efficiently, limiting user experience in terms of portability and convenience.
Innovation Solution
A slidable display device design featuring a display module with a support plate and case configuration that allows for adjustable exposure of the display surface through a sliding operation, utilizing a support unit with rollers and link units to maintain stability and expand the display area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a flexible display module is made expandable and portable, then user convenience and portability are improved, but the structural stability and support for the display module deteriorate
Solution Approach 1:
The support structure is divided into multiple support bars (first support bar, second support bar, third support bar, fourth support bar) that can independently extend and retract. Each support bar is coupled to the case through separate support rollers, allowing differential movement and maintaining stability while enabling expansion of the display module.
Solution Approach 2:
The support bars are designed to be movable rather than fixed, with support rollers that can rotate and extend/retract along the case. This dynamic structure allows the support system to adapt to different display module positions and sizes, maintaining stability during expansion and retraction operations.
2Area of moving object
If the display module is expanded to increase display area, then visibility and functionality are improved, but the complexity of the support mechanism increases
Solution Approach 1:
The support rollers serve multiple functions: they support the display module weight, enable expansion and retraction of support bars, and provide a mechanism for controlling the display module position. This multi-functionality reduces the need for additional separate components, thereby limiting the increase in overall system complexity.
Solution Approach 2:
The support bars are nested within the case structure, with the first and second support bars positioned inside the case and the third and fourth support bars extending outward. The support rollers are nested within grooves in the case, allowing compact storage when not in use and easy deployment when needed, minimizing the space required for the support mechanism.
3Reliability
If support bars are added to support the display module, then the support function is improved, but the device complexity and number of components increases
Solution Approach 1:
Multiple support functions are merged into a single integrated support plate structure that holds the display module, with support bars that can be extended or retracted as needed. The support rollers are integrated into the case structure, combining the support function with the housing function, thereby reducing the total number of separate components.
