Solution Overview
Problem
Smartboards often require after-sales service due to component failure or damage, causing user inconvenience and the need for systems that can minimize this disruption and allow for remote detection and repair of defects.
Innovation Solution
A power and video redundancy system comprising a main and sub video board, a video switching board, first and second power boards, a power redundancy module, and a control board that monitors and switches signals, generates alarm signals, and transmits failure messages, enabling seamless operation and remote diagnosis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single video board and single power board are used, then the device complexity is low, but the reliability deteriorates when components fail or break
Solution Approach 1:
The system divides the video processing function into separate main video board and sub video board, and divides the power supply function into first power board and second power board. This segmentation allows independent operation of each component, so when one fails, the other can continue functioning, thereby improving reliability without requiring a complete system redesign.
Solution Approach 2:
The patent implements redundancy by providing backup components (sub video board, second power board) that are prepared in advance. When the main video board or first power board fails, the system can immediately switch to the backup components through the video switching board and power redundancy module, cushioning against the impact of component failure before it disrupts operation.
2Reliability
If redundancy components are added, then the reliability improves, but the device complexity increases
Solution Approach 1:
The video switching board serves multiple functions: it switches video signals between main and sub video boards, monitors the operational status of video boards, and controls the connection to the display panel. The power redundancy module similarly handles both power distribution and fault detection. This multi-functionality reduces the need for separate dedicated components for each function, thereby managing complexity while maintaining reliability.
Solution Approach 2:
The video switching board acts as an intermediary between the video boards and the display panel, managing signal routing and fault isolation. The power redundancy module serves as an intermediary in the power distribution system, monitoring and managing power from multiple sources. These intermediary components centralize control functions, making the redundancy system more manageable and less complex than having fully distributed control.
3Ease of repair
If real-time monitoring is implemented, then the ease of repair improves, but the device complexity increases
Solution Approach 1:
The control board continuously receives feedback signals from the video boards through monitoring signals sent to input/output ports. When abnormality detection signals are received indicating component failure, the control board automatically switches to backup components. This feedback mechanism enables automatic fault detection and response, improving ease of repair by providing real-time system status information without requiring complex manual monitoring systems.
