Solution Overview

Problem

Mobile devices face unexpected power loss and data loss when a component cover is removed, as existing technologies do not adequately detect this event to initiate proper shutdown and data saving processes.

Innovation Solution

A warning and preparatory system for mobile devices, comprising a component cover with a detection portion, a sensor to detect the cover's removal, and a processor that pauses or closes power-consuming applications, saves critical data, and increases sampling rates to detect removable objects, allowing time for safe shutdown or data preservation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a component cover is removed from a mobile device, then access to battery or removable components is enabled, but unexpected power loss and data loss occur

Engineering Contradiction:
Improveaccess to batteryVSAvoidpower stability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The system performs preliminary detection of component cover removal and initiates shutdown procedures in advance before power loss occurs. The sensor detects cover removal, the processor identifies active applications, and data saving operations are launched proactively, transforming a reactive failure mode into a controlled preliminary action sequence.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system establishes a feedback loop where the sensor continuously monitors component cover status, provides real-time information to the processor, and triggers appropriate responses. This closed-loop feedback mechanism ensures that power loss scenarios are detected and addressed timely, preventing data loss by continuously observing system state changes.

Inventive Principle:
Principle #23Feedback

2Reliability

If the device is prepared for power loss by saving data, then data integrity is improved, but processing time and power consumption increase

Engineering Contradiction:
Improvedata integrityVSAvoidshutdown preparation time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The system performs data saving operations in advance upon detecting component cover removal, rather than waiting for power loss to occur. By initiating shutdown procedures preliminarily, the system ensures data is saved before the actual power failure, reducing the time loss associated with reactive shutdowns and ensuring data integrity.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system applies partial action by selectively saving only critical data and essential application states rather than all data. This partial approach to data saving reduces processing time and power consumption while still ensuring data integrity for the most important information, balancing reliability with time loss.

Inventive Principle:
Principle #16Partial or excessive action

3Use of energy by moving object

If applications are paused or closed to save power, then power consumption is reduced, but user experience and productivity are worsened

Engineering Contradiction:
Improvepower consumptionVSAvoidapplication execution
Core Design Contradiction:
Use of energy by moving objectVSProductivity

Solution Approach 1:

The system performs application management actions (pausing or closing) in advance upon detecting component cover removal, rather than waiting for power loss. This preliminary action allows the system to reduce power consumption proactively while giving users notice, thereby preserving productivity and user experience better than reactive measures.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system uses feedback from the sensor detection to trigger appropriate application management. By continuously monitoring component cover status and responding with appropriate application pauses or closures, the system balances power consumption reduction with productivity preservation, allowing users to understand and manage the impact on their applications.

Inventive Principle:
Principle #23Feedback
