Rotating Locking Structure for Flexible PCB Connection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display technologies face challenges in switching the connection mode between the printed circuit board and the back plate across different types of display devices, leading to reduced product applicability and increased assembly complexity and costs.
Innovation Solution
A connection mechanism featuring a chain structure of locking structures with movable assemblies allows for the adjustment of the printed circuit board's connection to the back plate, enabling it to be either parallel or folded to the back plate, thus accommodating different display device types.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed connecting device is used for a specific display type, then the connection is stable and simple to manufacture, but the product applicability is reduced and assembly complexity increases when adapting to different display types
Solution Approach 1:
The connecting device incorporates movable assemblies with rotating locking structures that can dynamically adjust between different connection modes. The locking structures can rotate relative to each other to switch between a first connection mode (for flat-screen displays) and a second connection mode (for curved-screen displays), transforming a static device into a dynamic one that adapts to different display types.
Solution Approach 2:
The connecting device is designed with multiple locking structures and movable assemblies that enable it to perform multiple functions - connecting both flat-screen displays and curved-screen displays using a single device. The locking structures can be positioned in different configurations to accommodate different connection requirements, making the device universal rather than specialized for one display type.
2Reliability
If different connecting devices are used for different display types, then each connection is optimized for its specific display type, but the number of parts increases and assembly costs increase
Solution Approach 1:
A single connecting device is designed with multiple locking structures and movable assemblies that enable it to connect both flat-screen displays and curved-screen displays. The locking structures can be positioned in different configurations to accommodate different connection requirements, eliminating the need for multiple specialized connecting devices while maintaining connection stability for each display type.
Solution Approach 2:
The connecting device is divided into multiple independent locking structures connected by movable assemblies. Each locking structure can independently adjust its position and orientation, allowing the device to adapt to different display types while maintaining stable connections. This segmentation enables one device to replace multiple specialized devices.
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
This solution enhances product applicability by allowing a single connection mechanism to support various display devices, reducing assembly difficulties and costs while ensuring stable connections.
Implementation Method 1
the electromagnet is arranged adjacent to the magnetic locking piece. When the electromagnet is powered off, the fixing teeth engage with the locking engaging teeth. When the electromagnet is energized, the electromagnet attracts the locking piece, and the fixing teeth are disengaged from the locking engaging teeth.

AI summary
A connection mechanism for connecting a printed circuit board and a back plate, and a display device are disclosed. The connection mechanism includes a connecting device and a fixing device, the connecting device having one side connected to the back plate, and another side connected to the fixing device. The fixing device is used to fix up the printed circuit board. The connecting device includes multiple locking structures connected end to end. A movable assembly is disposed on a side of a first locking structure facing towards the back plate, and there is further disposed a movable assembly between every two adjacent locking structures, which are rotatably connected together through the respective movable assembly. The multiple locking structures are operative to rotate relative to each other, driving the fixing device to be oriented parallel to the back plate or folded to a back of the back plate.
