Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a lack of display devices that can effectively reduce the size of organic light-emitting diode (OLED) displays by rolling them up, limiting their compactness and portability.
Innovation Solution
An OLED display device design featuring a support member with a central frame and slidably connected left and right frames, each with a sawtooth structure, allowing the frames to slide and roll the display support member and OLED display into the frames for compact storage, utilizing sliding rails and rolled springs for efficient rolling mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the OLED display is made foldable or rollable, then the display size can be reduced for compact storage, but the structural complexity increases due to additional frames and sliding mechanisms
Solution Approach 1:
The device is divided into multiple functional segments: a central frame, a display support member, and two separate sliding frames (left and right) with sawtooth structures. This segmentation allows each component to perform its specific function independently while contributing to the overall rolling capability, resolving the contradiction by organizing complexity into manageable modular units.
Solution Approach 2:
The sliding frames with sawtooth structures are designed to nest around the display support member during the rolling process. The left and right frames can be positioned inside or around the central frame when not in use, creating a compact nested configuration that reduces overall device volume while maintaining the rolling function when needed.
2Ease of operation
If the display support member is made flexible for rolling, then portability is enhanced, but the reliability of the OLED display may deteriorate due to potential damage from rolling and unrolling
Solution Approach 1:
The sawtooth structures on the sliding frames are designed to engage with corresponding features on the display support member before the rolling process begins. This pre-engagement provides protective guidance and cushioning during the rolling action, preventing sudden movements or improper folding that could damage the OLED display, thus maintaining reliability while enabling portability.
Solution Approach 2:
The sliding frames act as intermediary protective structures between the user's rolling action and the OLED display itself. These frames with sawtooth structures guide the rolling process and provide a mechanical interface that protects the fragile OLED display from direct stress or improper handling, ensuring durability while enabling flexible operation.
3Volume of moving object
If the left and right frames are made slidable for expansion and contraction, then the display can be compacted for carrying, but the ease of operation may worsen due to the complexity of the sliding mechanism
Solution Approach 1:
The left and right frames are designed with sliding capabilities that allow dynamic transformation between expanded and contracted states. The sawtooth structures enable controlled movement along the display support member, allowing the device to adapt its configuration from a compact carried state to an expanded display state through simple sliding motions, maintaining operational simplicity despite the dynamic functionality.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution enables the reduction of display size, enhancing convenience in carrying and maintaining a flat, expanded display state while ensuring the OLED display is protected from direct pulling.
Implementation Method 1
the interior of the left frame further includes a left rolled spring, the left rolled spring is connected to the left side of the display support member, when the left frame slides toward the central frame, a part of the display support member and a part of the OLED display are rolled into the interior of the left frame

AI summary
The present disclosure provides an organic light emitting diode (OLED) display device, including a support member, a central frame disposed on the display support member. A left frame slidably connected to the central frame. A right frame slidably connected to the central frame. The OLED display is rolled up or stretched by sliding the left frame and the right frame. Therefore, space of large display is reduced, and convenience of carrying is enhanced.
