Redundancy Board for Display Power Supply Flexibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current display systems face challenges in achieving high uptime and flexibility due to proprietary power supply redundancy requirements, which limit design modifications and increase costs, as they often necessitate proprietary built-in redundancy solutions from specific manufacturers.
Innovation Solution
A power-supply redundancy system that uses generic power supplies without built-in redundancy, utilizing a redundancy board to connect multiple primary and redundant power sources to display components, allowing for flexible power routing and detection of failures, thereby eliminating the need for proprietary solutions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If proprietary built-in redundancy architecture from power supply manufacturers is used, then power supply redundancy is achieved, but design flexibility is limited and costs increase
Solution Approach 1:
The power supply system is segmented into separate functional components: primary power supplies, redundant power supplies, and a power distribution unit. This segmentation allows each component to be independently selected and configured, enabling design flexibility while maintaining redundancy capabilities without requiring proprietary built-in solutions
Solution Approach 2:
The power distribution unit serves multiple functions: it receives power from primary power supplies, monitors their status, switches to redundant power supplies when failures are detected, and distributes power to display components. This multi-functional approach eliminates the need for proprietary redundant power supplies while achieving the same reliability goals
2Reliability
If proprietary built-in redundancy architecture from power supply manufacturers is used, then power supply redundancy is achieved, but system costs increase
Solution Approach 1:
The system uses standard, off-the-shelf power supply units rather than expensive proprietary redundant power supplies. The power distribution unit implements redundancy management logic that allows the use of conventional power supplies in a redundant configuration, significantly reducing component costs while maintaining reliability
Solution Approach 2:
The power distribution unit acts as an intermediary between primary/redundant power supplies and display components. It implements the redundancy management functionality that would otherwise require proprietary power supplies, thereby reducing system cost while maintaining power supply redundancy
3Reliability
If proprietary power supply solutions are used, then power supply requirements are met, but design modifications are limited
Solution Approach 1:
By separating the power distribution function from the power supply units themselves, the system allows independent modification of each component. The power distribution unit can be redesigned to accommodate different power supply types or configurations without changing the power supply units, and vice versa, enabling design flexibility while maintaining power continuity

AI summary
A system comprises a redundancy circuit board including a plurality of primary input connectors each connectible to a primary power supply that supplies primary electrical energy, a redundancy power input connector connectible to a redundant power supply that supplies redundant electrical energy, a plurality of output connectors connectible to a display component powerable by the primary or redundant electrical energy, and a plurality of electrical pathways including primary pathways each connecting a primary input connector to a corresponding output connector, redundant pathways each connecting the redundancy input connector to a corresponding output connector. The system also includes one or more electrical devices that detect whether primary electrical energy has been interrupted along a first primary pathway, activate the redundant power supply to supply redundant electrical energy to the redundancy input connector, and direct redundant electrical energy along a first redundant pathway to the first output connector.
