Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the OLED display device is designed with a fixed planar structure, then the manufacturing is simple, but the device cannot transition to a standing state, reducing versatility
Solution Approach 1:
The patent applies the dynamics principle by transforming the fixed planar structure into a dynamic structure that can transition between planar and standing states. The first and second shells are connected through rotatable first rods and sliding mechanisms (sliders and chutes), enabling the device to change its spatial configuration from a flat state to an upright standing state, thereby achieving state transition capability while maintaining reasonable structural complexity
Solution Approach 2:
The patent segments the device into distinct functional modules: first shell, second shell, support plate, first rods, sliders, and chutes. This segmentation allows each component to perform its specific function in the state transition mechanism, making the overall system more manageable and easier to manufacture despite the added versatility
2Ease of manufacture
If the device structure is simplified for easy manufacture, then the manufacturing cost is reduced, but the friction between moving parts increases, affecting smooth operation
Solution Approach 1:
The patent introduces pulleys as intermediary elements between the OLED panel and the first/second shells, and between the OLED panel and the support plate. These pulleys act as mediators that reduce friction during the state transition process, allowing the OLED panel to move smoothly relative to the shells and support plate without requiring complex high-precision manufacturing
Solution Approach 2:
The patent changes the friction parameter by introducing pulley mechanisms that transform the interaction between surfaces. Instead of direct contact between the OLED panel and shells, the pulleys create a rolling contact system that significantly reduces friction, enabling smooth operation while maintaining simple manufacturing requirements for the individual components
3Ease of operation
If the OLED panel is allowed to move freely during state transition, then the operation is smooth, but the panel may lose contact with the shells, reducing stability
Solution Approach 1:
The patent employs spiral springs as flexible elastic elements that continuously press the OLED panel against the first and second shells during state transition. This flexible contact mechanism allows the panel to move smoothly through the transition while maintaining stable contact, combining ease of operation with structural stability without requiring rigid constraints

Function Achieved in This Case
Enables smooth transition between planar and standing states while ensuring the OLED panel remains closely contacted with the shells and support plate, reducing friction and enhancing portability and usability.
Implementation Method 1
two spiral springs respectively disposed in the first shell and the second shell, and respectively connected to the two opposite sides of the OLED panel. The spiral springs are configured to make the OLED panel closely contact the first shell, the second shell, and the support plate
Implementation Method 2
two pulleys respectively disposed in the first shell and the second shell, which are used to reduce friction between the OLED panel and the first shell and friction between the OLED panel and the second shell
Implementation Method 3
two rotating shafts respectively disposed on two opposite sides of the support plate, which are used to reduce friction between the OLED panel and the support plate

AI summary
The present disclosure provides a standable OLED display device comprising a first shell, a second shell, a support plate, four first rods, and an OLED panel. The first shell and the second shell have sliders and chutes. Each slider partially slides in a corresponding chute. Two first rods are rotatably connected to the first shell and the support plate. Two other first rods are rotatably connected to the second shell and the support plate. The OLED panel is disposed on the support plate, the first shell, and the second shell, and two opposite sides thereof are respectively inserted in the first shell and the second shell. When the first shell and the second shell slide close to each other, the support plate rises in parallel with respect to the first shell and the second shell so that the device is changed from an initial planar state to a standing state.
