Signal Box Interconnect for Tiled Display Cabling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Tiled display systems require numerous cumbersome and difficult-to-maintain cables for power, control, and video signals, making assembly and troubleshooting complex, especially with bulky DVI cables that hinder alignment and diagnostic operations.
Innovation Solution
A signal box (sbox) provides both power and data packets to a display device via a single interconnect, using shielded category-6 cables that can transmit data and power bi-directionally, simplifying cabling and enabling easier maintenance and diagnostics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If dedicated power cables, control cables, and video cables are used for each display module, then each display module can receive power and signals, but the number of cables increases making assembly and maintenance cumbersome
Solution Approach 1:
The patent combines power delivery, control signals, and video signals into a single integrated cable connection. The first cable delivers both power and data packets to the display module, eliminating the need for separate dedicated cables for each function and reducing overall cabling complexity
Solution Approach 2:
The cable connection is designed to perform multiple functions simultaneously - it serves as both a power delivery conduit and a data transmission channel. This multi-functional approach allows a single cable to replace what would traditionally require three separate cables
2Reliability
If bulky DVI cables are used for video signals, then digital video transmission is achieved, but the cables have high bending radius making assembly and maintenance difficult
Solution Approach 1:
The patent changes the physical parameters of the cable by using flexible category-6 cables instead of rigid DVI cables. This parameter change allows the cable to be routed more easily around display modules with smaller bending radii while still maintaining digital video transmission capability
Solution Approach 2:
The patent replaces the mechanical connection requirements of rigid DVI cables with the flexibility of category-6 cables. This substitution allows for easier routing and connection while maintaining the electrical functionality for video signal transmission
3Adaptability or versatility
If additional cables are coupled to each display device for alignment and diagnostic operations, then alignment and diagnostics can be performed, but the complexity of cabling increases when already installed
Solution Approach 1:
The single cable connection is designed to carry multiple types of data packets including alignment commands and diagnostic information. This universal data channel allows alignment and diagnostic operations to be performed through the existing cable without requiring additional dedicated cables
Solution Approach 2:
The system uses the existing cable infrastructure to perform self-diagnosis and self-alignment functions. The display module can receive diagnostic and alignment data packets through the same cable used for normal operation, eliminating the need for separate diagnostic cables
