Boot Control for FDB Hard Disks in Low Temperatures
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional hard disks with Fluid Dynamic Bearing (FDB) technology fail to operate properly in low-temperature environments without a heating module, as the liquid film solidifies, leading to potential damage and boot failures in electronic devices, especially with removable hard disks where the user is unaware of the heating module's presence.
Innovation Solution
An electronic device with a boot determining method that includes detecting ambient temperature, determining the type of storage, and checking for a heating module, allowing safe booting by either preheating with a heating module or shutting down to prevent damage when the temperature is below zero degrees Celsius.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If FDB hard disk is used to improve shock resistance and service life, then reliability is improved, but in low temperature environment the liquid film solidifies causing abnormal operation and potential damage
Solution Approach 1:
The system performs preliminary detection of ambient temperature and heating module presence before booting the FDB hard disk. When temperature is below threshold and heating module is absent, the system prevents booting in advance, avoiding the harmful effect of solidified liquid film damage.
Solution Approach 2:
The patent introduces an intermediary detection and determination system that checks temperature and heating module status between the environment and the FDB hard disk. This intermediary layer provides warning information and controls booting based on the detected conditions, preventing direct exposure to harmful low-temperature effects.
2Ease of operation
If removable hard disk is allowed for user convenience, then ease of operation is improved, but user cannot know whether heating module is present leading to boot failures
Solution Approach 1:
The system provides feedback by detecting the presence of heating module and ambient temperature, then determining and communicating the bootability status. This feedback loop informs users or system about whether the removable FDB hard disk can be safely booted, compensating for the user's lack of knowledge about heating module presence.
Solution Approach 2:
The system performs self-service by automatically detecting temperature and heating module status, and making the booting determination without requiring user knowledge or action. The system serves itself by monitoring its own environmental conditions and storage device status.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Ensures safe booting of electronic devices in low-temperature environments by automatically determining the need for a heating module, preventing damage to FDB hard disks and ensuring normal operation of solid state disks, thus extending the service life and reliability of storage devices.
Implementation Method 1
The heating module may preheat the FDB hard disk to change the film of the FDB hard disk into a liquid phase before the FDB hard disk operates
Implementation Method 2
when the ambient temperature is below zero degrees Celsius, the liquid film of the FDB may be changed into a solid phase

AI summary
A boot determining method of an electronic device is used to determine whether to boot the electronic device having at least one storage. The boot determining method includes: receiving a start signal; detecting an ambient temperature; detecting whether the at least one storage has a heating module; comparing the ambient temperature with a temperature threshold; reading storage information; determining type(s) of the at least one storage according to the storage information; and determining whether to boot the electronic device after receiving the starting signal, according to a determining condition. The determining condition includes the type(s) of the at least one storage; whether the environment temperature is lower than the temperature threshold; and whether each of the at least one-storage has the heating module.
