Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a connecting device is designed for a specific display type (flat-screen or curved-screen), then the connection stability is improved, but the product applicability deteriorates
Solution Approach 1:
The connecting device is designed with a chain structure comprising multiple locking structures that can rotate relative to each other, enabling the securing device to assume different orientations (parallel or folded). This multi-functional design allows a single connecting device to accommodate both flat-screen and curved-screen displays, resolving the contradiction between connection stability for specific types and overall product applicability.
Solution Approach 2:
The locking structures are designed to be rotatable relative to one another, transforming the rigid, fixed-orientation connecting device into a dynamic structure. This dynamic capability enables the securing device to adapt its orientation based on the display type, maintaining reliable connection while expanding versatility across different display configurations.
2Manufacturing precision
If different connecting devices are used for different display types, then the connection precision is improved, but the device complexity and assembly costs increase
Solution Approach 1:
Multiple locking structures are merged into a single chain structure where each locking structure can rotate relative to the others. This integration allows the system to provide precise connection for different display types without requiring separate connecting devices, thereby reducing device complexity and assembly complexity while maintaining connection precision.
3Reliability
If multiple connecting devices are maintained for different models, then the connection reliability for each model is improved, but the loss of substance increases
Solution Approach 1:
The connecting device with rotatable locking structures serves multiple display models and types with a single design. This universality eliminates the need to maintain separate connecting devices for different models, ensuring reliable connection for each while reducing inventory requirements and associated costs.
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
Enables flexible and stable connection of printed circuit boards to back plates across different display types, improving product applicability and reducing assembly complexity and costs by allowing for easy switching between connection modes.
Implementation Method 1
The movable assembly includes an electromagnet, an elastic piece, and a stopper piece. The electromagnet is arranged adjacent to the connecting plate of the first locking structure. When the electromagnet is powered off, the electromagnet repels the stopper piece, and the stopper piece is engaged with the rotating body in the second locking structure. When the electromagnet is energized, the electromagnet attracts the stopper piece, and the stopper piece is separated from the rotating body in the second locking structure.

AI summary
A connection mechanism and a display device are disclosed. The connection mechanism is used to connect a printed circuit board and a back plate. The connection mechanism includes a connecting device and a securing device. One side of the connecting device is connected to the back plate, and another side is connected to the securing device. The securing device is used to fix up the printed circuit board. The connecting device includes multiple locking structures connected end to end. The multiple locking structures are operative to rotate relative to each other thus driving the securing device to be oriented parallel to the back plate or be folded to a back of the back plate.
