Retractable LED Box Connector for Collision-Free Display Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The assembly of LED boxes is cumbersome due to the need for manual wiring, which can result in lamp beads being impacted during connection.
Innovation Solution
A connecting device with a first and second plugging portion, a fixed seat, a driving portion, and an elastic reset member, allowing for automatic extension and retraction of the second plugging portion to connect and disconnect LED boxes without protruding and preventing collisions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If connectors are fixed on side walls of LED boxes, then manual wiring is eliminated, but lamp beads are impacted due to collision between boxes
Solution Approach 1:
The connector is designed with a movable plugging portion that can extend and retract relative to the box body. During assembly, the plugging portion retracts to avoid collision with adjacent boxes, while during operation it extends to establish electrical connection, thus eliminating both the collision problem and manual wiring
Solution Approach 2:
The connector incorporates an elastic reset member that automatically drives the plugging portion to extend or retract based on the assembly state. When boxes are pushed together during assembly, the plugging portion automatically retracts; when assembled, it automatically extends to connect, eliminating the need for manual intervention
2Ease of manufacture
If rear housing is opened for wiring, then wires can be hidden for aesthetic and protection, but assembly steps become complex and cumbersome
Solution Approach 1:
The connector is extracted from the traditional fixed position on the rear housing and relocated to the side wall with movable capability. This allows wires to remain hidden while eliminating the need to open and close the rear housing, simplifying assembly steps
Solution Approach 2:
The side wall connector serves multiple functions: it provides electrical connection, enables automatic engagement during assembly, and maintains aesthetic appearance by keeping wires hidden, replacing the need for rear housing operations
