Modular LED Sign System with Quick-Disconnect Waterproof Cabling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current LED sign systems take weeks to assemble, install, and deploy, requiring skilled tradesmen and exposing power and data cables to environmental damage, making them susceptible to failure and costly to install.
Innovation Solution
A rapidly-deployable, configurable modular LED sign system using interlocking sections with alignment pins and quick-disconnect waterproof cabling, allowing non-tradesmen to assemble and install the system quickly, with integrated power and data management, and protection from environmental factors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional LED sign systems are assembled using welders and electricians, then structural integrity and electrical connections are ensured, but installation time increases to over 10 weeks and labor costs increase significantly
Solution Approach 1:
The LED sign system is divided into modular cabinet sections that can be pre-assembled and tested separately, then quickly interconnected on-site using mechanical attachment mechanisms rather than requiring complete on-site fabrication
Solution Approach 2:
The modular sections include self-contained electrical systems with pre-installed connectors and wiring, allowing the sections to be interconnected without requiring external electricians to perform complex wiring tasks during installation
2Stability of the object's composition
If LED sign sections are securely fastened to prevent movement, then structural stability is improved, but accessibility for troubleshooting and maintenance decreases
Solution Approach 1:
The attachment mechanism transitions from a permanently fixed state to a dynamically adjustable state, allowing the same connection to provide both secure structural attachment during operation and easy accessibility during maintenance through simple tool-based release mechanisms
3Ease of operation
If power and data cables are exposed for easy connection, then ease of installation is improved, but susceptibility to environmental damage increases
Solution Approach 1:
The power and data connection functions are merged into a single integrated connector assembly that is housed within the protected cabinet structure, allowing both electrical connections to be made simultaneously while both cables remain protected from environmental exposure
4Productivity
If modular sections are designed for quick assembly, then installation speed is improved, but structural rigidity may decrease
Solution Approach 1:
The structural reinforcement elements are pre-positioned and pre-configured within each modular section during manufacturing, so that when sections are assembled on-site, the structural integrity is automatically provided without requiring additional time-consuming field operations

AI summary
A rapidly-deployable, configurable, modular light emitting diode sign system comprising a modular rigid cabinet with a cavity therein receiving system components where each cabinet has a front opening with releasable fasteners, a lock, and cable channels. A light emitting diode panel covering the front opening and receiving communication from the controller regarding messages to be displayed. A shipping package system having a box and shock absorbers sized to receive a display to snugly fit inside the box protecting the display from damage during shipment whereby each cabinet with needed components are shipped in the same box so that an installer desiring to create a sign of a specified size by mulling together a number of cabinets, receives the needed number of boxed cabinets, assembles them using the shipped equipment, with minimal tools or additional parts, and without the need to modify the displays onsite to mull them together.
