Docking Protection Circuit for Computing Terminal Power Delivery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional computing networks face disruptions and safety hazards due to short circuits, which require manual user intervention to resolve, causing power interruptions and potential fires or explosions.
Innovation Solution
A docking arrangement with a protection circuit that monitors current supply to computing terminals, automatically decouples and recouples them from the power source to prevent excessive power delivery, allowing continuous operation of other terminals without user intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If power delivery is terminated to all terminals when a short circuit is detected, then safety hazards (fire, explosion) are prevented, but operation of non-shortcircuited terminals is interrupted
Solution Approach 1:
The patent segments the power delivery system by implementing individual protection circuits for each terminal. When a short circuit is detected in one terminal, only that specific terminal is disconnected from power, while other terminals continue to receive power normally. This segmentation resolves the contradiction by preventing safety hazards at the affected terminal without interrupting operation of other terminals.
Solution Approach 2:
The patent applies local quality protection by providing dedicated protection circuits tailored to each terminal's specific characteristics. Each terminal has its own protection circuit that monitors and controls power delivery independently, allowing localized response to short circuits without affecting the entire system.
2Reliability
If power delivery is terminated to all terminals when a short circuit is detected, then excessive power delivery to the shorted terminal is prevented, but manual reset is required causing user intervention
Solution Approach 1:
The patent implements self-service through automatic protection circuit operation. When a short circuit is detected, the protection circuit automatically disconnects the affected terminal and can automatically reconnect it when the short circuit is resolved, eliminating the need for manual user intervention and resetting operations.
Solution Approach 2:
The protection circuits continuously monitor terminal conditions and provide feedback to control power delivery automatically. This feedback mechanism enables the system to detect short circuits, respond appropriately, and restore normal operation without requiring user intervention.
3Use of energy by moving object
If excessive power is delivered to a shorted terminal, then charging speed is maintained, but heat generation increases causing safety hazards
Solution Approach 1:
The patent converts the harmful effect of excessive current into a beneficial protective action. The protection circuit detects the excessive current (which would cause heat and safety hazards) and uses this information to disconnect the terminal, preventing the harmful thermal effects while maintaining normal charging operation for other terminals.

AI summary
Described is a method wherein a computer terminal is coupled to a power supply through a docking arrangement. The docking arrangement includes a protection circuit. A current supplied to the computing terminal is detected. When the current is greater than a predetermined value, the computer terminal is decoupled from the power supply. After the computer terminal is decoupled from the power supply, the computer terminal is recoupled to the power supply, and the method repeats beginning with detecting the current supplied to the computing terminal.
