Solution Overview

Problem

Electronic devices face damage and data loss due to sudden power off events, as existing technologies cannot perform power-off sequences when power is suddenly interrupted, leading to potential component damage and data loss.

Innovation Solution

An electronic device design that includes a substrate with connectors and wires, storage devices, and a battery module configured to supply auxiliary power to storage devices through a shared register, allowing components to independently manage sudden power off events by interacting through a backplane, ensuring data integrity and component protection.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If power is suddenly turned off due to power failure or abnormal operation, then power supply is interrupted, but components may be damaged and data may be lost

Engineering Contradiction:

Improvecomponent safetyVSAvoidsudden power off damage

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The battery is pre-charged during normal operation and automatically activates to provide auxiliary power when a sudden power off event is detected, enabling the storage device to complete its power-off sequence without damage. This preliminary preparation of power supply capability resolves the contradiction by ensuring component safety during unexpected power interruptions.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The battery serves as a cushioning power supply that absorbs the shock of sudden power interruption. By providing backup power capacity in advance, it protects the storage device and other components from the harmful effects of abrupt power loss, preventing damage while maintaining system reliability.

Inventive Principle:

Principle #11Beforehand cushioning (Prior cushioning)

2Productivity

If power off sequence is not performed due to sudden power interruption, then power can be immediately restored, but data may be lost and components damaged

Engineering Contradiction:

Improvepower restoration speedVSAvoiddata loss

Core Design Contradiction:

ProductivityVSLoss of information

Solution Approach 1:

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The battery maintains continuous power supply to the storage device during the transition from normal power to power loss condition. This continuity allows the power-off sequence to complete uninterrupted, preserving data integrity while enabling quick restoration of full power operation without data loss or component damage.

Inventive Principle:

Principle #20Continuity of useful action

3Reliability

If battery supplies auxiliary power to all components, then all components are protected, but power management complexity increases

Engineering Contradiction:

Improvesystem protectionVSAvoidpower management complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The battery is configured to provide auxiliary power specifically to storage devices that require it during sudden power off events, rather than uniformly to all components. This selective power distribution reduces power management complexity while maintaining protection for critical components that need it most.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

Storage devices are equipped with the capability to independently detect sudden power off events and request auxiliary power from the battery through interaction via backplane. This self-service approach allows each component to manage its own power protection needs, reducing overall system complexity while maintaining comprehensive protection.

Inventive Principle:

Principle #25Self-service
