Display Connection Module With Rotating Latch for Fast Panel Replacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display systems require complex and time-consuming processes for connecting and maintaining display devices, especially when a single device in the center needs repair, necessitating the removal of non-damaged devices in the same column or row.
Innovation Solution
A display device with a rotatable knob, restriction unit, and sliding connectors that allow easy assembly and disassembly, enabling individual device replacement without affecting adjacent units, using magnets, screws, and buckling portions for secure attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If latches or bolts are used to connect display devices, then the connection between devices is secure, but the assembly and disassembly process becomes time-consuming and complex
Solution Approach 1:
The latch structure is designed to be dynamic rather than static. The button can be pressed to release the latch, transforming the connection from a permanently fixed state to a easily reversible state. This allows secure connection during operation while enabling quick disassembly when needed, resolving the contradiction between connection security and assembly time.
Solution Approach 2:
The latch mechanism is designed to be self-locking without requiring additional fastening actions. Once the display devices are pushed together, the latch automatically engages to secure the connection. Conversely, pressing the button automatically releases the latch. This self-service mechanism eliminates the need for complex manual operations, reducing assembly and disassembly time while maintaining secure connection.
2Stability of the object's composition
If latches or bolts are used to connect display devices, then the connection is stable, but the maintenance process becomes complex requiring removal of multiple devices
Solution Approach 1:
The connection mechanism is segmented into independent latch units, with each display device having its own latch controlled by a button. This segmentation allows individual devices to be detached independently without affecting the connection status of adjacent devices. During maintenance, only the damaged device needs to be accessed and its own latch released, eliminating the need to remove entire rows or columns of devices.
Solution Approach 2:
Each display device is equipped with its own button-controlled latch that can be independently activated. This self-service design enables any single device in the matrix to be quickly released and removed for maintenance without requiring intervention with or removal of other devices. The independent control of each latch simplifies the maintenance process significantly while maintaining stable connections during normal operation.
3Area of stationary object
If multiple display devices are arranged in a matrix and connected with latches or bolts, then the display system can show huge images, but the mounting and maintenance costs increase
Solution Approach 1:
The display system is segmented into modular display devices that can be independently connected and disconnected. Each device has its own button-controlled latch mechanism, allowing individual access and removal. This modular segmentation enables the construction of large-area display walls while keeping each unit independently maintainable, reducing overall system complexity for mounting and maintenance compared to integrated systems.
Solution Approach 2:
The connection system uses dynamic button-controlled latches instead of static permanent fastenings. This allows the display system to transition between a stable, integrated state during operation and an easily reconfigurable state during maintenance or reconfiguration. The dynamic nature of the connection mechanism reduces long-term operational complexity while maintaining the ability to create large display areas.

AI summary
A display device is provided. The display device includes a device housing, a knob, a restriction unit and a screen panel. The knob is rotatably connected to the device housing, wherein the knob comprises a latch and a plurality of teeth, the knob is adapted to be rotated between a first knob location and a second knob location, and when the knob is in the first knob location, the latch protrudes from the device housing, and when the knob is in the second knob location, the latch is received in the device housing. The restriction unit is disposed in the device housing, wherein the restriction unit is adapted to be connected to one of the teeth to restrict the knob. The screen panel is detachably connected to the device housing. The display device can be easily detached from a display system.
