Battery Suspension Mechanism for Mobile Device Shutdown Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users often remove batteries from mobile devices without properly shutting down the device and its applications, leading to potential data loss and corruption.
Innovation Solution
A method utilizing a suspension mechanism that determines if the mobile device is shut down and releases the power supply based on the time necessary for proper shutdown, using mechanisms like solenoids, clamps, or dynamic alloys to prevent improper battery removal, and includes a mechanical back-up release system for solenoid failure cases.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a suspension mechanism is used to prevent improper battery removal, then data loss and corruption are prevented, but device complexity increases
Solution Approach 1:
The patent replaces complex mechanical suspension mechanisms with an electronic/software-based solution. The system uses a shutdown indicator flag and timeout mechanism to control battery removal, eliminating the need for physical suspension hardware while achieving the same reliability goal of preventing data loss during improper removal.
Solution Approach 2:
The system automatically monitors shutdown status and controls battery removal eligibility without requiring user intervention. The shutdown indicator flag and timeout mechanism autonomously determine when it is safe to remove the battery, making the system self-regulating and reducing overall complexity.
2Reliability
If the system waits for complete shutdown before allowing battery removal, then data corruption is prevented, but loss of time occurs
Solution Approach 1:
The system performs preliminary shutdown of critical processes and sets the shutdown indicator flag before the user attempts battery removal. This preliminary action ensures that essential data protection measures are in place before removal occurs, reducing the required wait time while maintaining data integrity.
Solution Approach 2:
The system implements a timeout mechanism that allows battery removal after a predetermined time period regardless of complete shutdown status. This partial action approach balances data protection with user convenience, preventing most data loss scenarios while avoiding excessive delays in battery removal.
