Socket Stabilization in LCD Shield Case Offset
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The frequent attachment and detachment of power supply plugs in liquid crystal displays often cause the socket to move, detach, or break, leading to potential damage to the circuit board.
Innovation Solution
A fastening element with protruding and raised portions is integrated into the metal shield case's offset portion to secure the socket, constraining its horizontal and vertical movements, ensuring it remains in position during assembly and disassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the socket is left without fastening structure, then the device structure remains simple, but the socket moves, detaches, or breaks during frequent power supply plug attachment and detachment
Solution Approach 1:
The fastening element is integrated directly into the offset portion of the shield case, merging the fastening function with the existing structural component. This eliminates the need for separate fastening parts while providing stable socket fixation through protruding and raised portions that constrain socket movement.
Solution Approach 2:
The fastening element is designed to automatically secure the socket in position without requiring additional fastening operations or external mechanisms. The protruding and raised portions inherently constrain the socket's movement, providing self-contained stabilization during power supply plug attachment and detachment.
2Strength
If the socket is secured with fastening element, then the circuit board is protected from damage, but the manufacturing process becomes more complex
Solution Approach 1:
The fastening element is combined with the offset portion of the shield case, allowing both the shielding function and socket fastening to be achieved in a single component. This integration simplifies the overall assembly process while providing robust protection for the circuit board against socket movement and detachment.

AI summary
A liquid crystal display device includes a liquid crystal display module, a circuit board, and a shield case. The circuit board is mounted on the liquid crystal display module and has a socket for receiving a power supply plug. The shield case includes an offset portion on a rear part to contain the circuit board. An opening formed with holding members for securing the socket is provided at the offset portion.
