Automatic Power Control for Removable Components
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users often remove components from electronic devices without shutting them down, risking electrical damage during upgrades or servicing.
Innovation Solution
An automatic trigger or button coupled to a component power controller is used to detect changes in component positions, initiating a power shut-down of removable components when they become accessible, ensuring safe removal and installation without requiring a complete system shutdown.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the entire electronic device is shut down to prevent electrical damage during component removal, then component safety is improved, but device productivity and user convenience deteriorate
Solution Approach 1:
The power control system is segmented to allow independent power management of different component groups. The controller can shut down power to specific removable components (in the keyboard receptacle) while maintaining power to other essential components, enabling partial shutdown rather than complete system shutdown.
Solution Approach 2:
The system performs preliminary detection of component positions and automatically initiates power shut-down to removable components before the user attempts removal. This preliminary action prevents electrical damage without requiring the user to manually shut down the entire device first.
2Ease of operation
If power is continuously supplied to removable components for easy access, then ease of operation is improved, but risk of electrical damage increases
Solution Approach 1:
The system continuously monitors component positions through triggers or sensors and provides feedback to the power controller. When a component is detected to be in a removable position, the controller automatically adjusts power supply accordingly, creating a closed-loop safety mechanism.
Solution Approach 2:
The system automatically detects component positions and manages power supply without requiring user intervention. The triggers or sensors self-activate the power control sequence when components are moved to accessible positions, making the safety mechanism autonomous.
3Reliability
If automatic power detection and control systems are implemented, then component protection is improved, but device complexity increases
Solution Approach 1:
The patent extracts the power control function into a separate, dedicated controller that independently manages power to removable components. This modular approach contains the complexity within a specific component rather than distributing it throughout the entire system.
Solution Approach 2:
Triggers or sensors serve as intermediaries between the physical component position and the power control system. These simple detection elements translate mechanical positions into control signals, simplifying the interface between the user action and the complex power management logic.
