LED Display Module Connector Layout for Impact-Resistant Contact Hold
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing LED display screens suffer from instant black screens when impacted by objects due to disengagement of the board-to-board connector contacts, leading to unreliable connections and frequent replacements.
Innovation Solution
An LED display screen design featuring a frame with modules and a power box, where the control board is divided into a main and sub-control board connected via a board-to-board connector, with an elastic mechanism between the sub-control board and the power box, allowing synchronous movement away from the display surface upon impact while maintaining contact positions, preventing disengagement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a board-to-board connector is soldered to the LED light board to connect the control board and module, then the connection structure is simple and convenient for quick disassembly, but when the LED light board is impacted by objects at high speed, the connector moves backward causing contact detachment and instant black screen
Solution Approach 1:
The control board is divided into a main control board and at least one sub-control board, with the sub-control board positioned closer to the LED light board. This segmentation allows the sub-control board to absorb impact forces independently through the elastic mechanism, protecting the main control board and ensuring continuous operational reliability.
Solution Approach 2:
An elastic mechanism is introduced between the sub-control board and the power box to provide beforehand cushioning. This elastic mechanism allows the sub-control board to move backward synchronously with the LED light board during impact while maintaining contact reliability, preventing the instant black screen problem that occurs with rigid connections.
2Reliability
If a cable socket is provided on the LED module and connected to the control board by a cable, then the connection is robust, but the structure becomes complex and expensive requiring waterproof covers and rubber joints
Solution Approach 1:
The board-to-board connector integrates the connection function that previously required separate cable, socket, and waterproof cover components. By merging these elements into a single integrated connector, the design achieves robust electrical connection while eliminating the complex waterproof structure required by cable-based solutions.
Solution Approach 2:
The cable and external waterproof covering components are extracted from the system by using an integrated board-to-board connector. This extraction simplifies the overall structure while maintaining connection reliability, as the connector is designed to function without external waterproof protections.
3Stability of the object's composition
If the LED light board is made rigid to maintain display stability, then the display structure is stable, but impact forces cause the board-to-board connector to detach and create instant black screens
Solution Approach 1:
The sub-control board is designed with dynamic movement capability through the elastic mechanism, allowing it to move backward synchronously with the LED light board during impact. This dynamic design maintains connector contact reliability under impact conditions while the LED light board itself maintains its rigid structure for display stability.
Solution Approach 2:
The elastic mechanism acts as an intermediary between the rigid LED light board and the sub-control board. It mediates the impact forces by allowing controlled movement, preventing direct transmission of shock that would cause connector detachment, while maintaining overall structural stability.
