Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing computer devices and servers face challenges in maintaining functionality during power failures without the need for large, expensive batteries, which are burdensome for maintenance and occupy unnecessary space, especially when only partial system recovery is required upon power restoration.
Innovation Solution
A computer device with a power supply unit that includes an instantaneous power failure resistance capacitor to convert AC to DC and a main body with a non-volatile storage unit, where a power failure detection unit instructs the processor to convert volatile data into reusable data and transfer it to a non-volatile storage area, eliminating the need for additional power supply devices like batteries.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a battery is used to maintain device function during power failure, then the device can continue operating during power failure, but the device becomes large, expensive, and heavy
Solution Approach 1:
The patent extracts the power supply function during power failure from a battery and implements it using an existing capacitor component already present in the power supply unit. The capacitor 115, which is part of the AC power supply circuit, is utilized to provide power during instantaneous power failures, eliminating the need for a separate battery component.
Solution Approach 2:
The capacitor 115 in the power supply unit is given a dual function: it serves both as a power supply smoothing component during normal operation and as a power source during instantaneous power failures. This multi-functionality eliminates the need for dedicated battery components while maintaining power failure continuity.
2Reliability
If a battery is used to maintain device function during power failure, then the device can continue operating during power failure, but the device becomes expensive
Solution Approach 1:
The capacitor 115 is designed to perform multiple functions including power smoothing during normal operation and power supply during power failures. This eliminates the need for additional battery components, reducing manufacturing costs while maintaining reliability.
Solution Approach 2:
The power failure protection function is merged with the existing power supply circuit by utilizing the capacitor 115 that is already part of the AC power supply unit. This integration eliminates the need for separate battery components and their associated costs.
3Reliability
If a battery is used to maintain device function during power failure, then the device can continue operating during power failure, but the device requires maintenance and replacement
Solution Approach 1:
The patent removes the battery component from the system and replaces its function with an existing capacitor. Since capacitors have no moving parts and longer operational life compared to batteries, this eliminates maintenance and replacement requirements.
Solution Approach 2:
The capacitor 115, being a solid-state component with no chemical degradation like batteries, provides a maintenance-free solution. While capacitors do have limited lifespans, they generally outlast batteries and require no maintenance during their operational life.
4Reliability
If a battery is used to maintain device function during power failure, then the device can continue operating during power failure, but the device occupies unnecessary space
Solution Approach 1:
The patent extracts the power failure protection function from a separate battery component and implements it within the existing power supply unit using capacitor 115. This eliminates the need for additional space-dedicated battery compartments.
Solution Approach 2:
The power failure protection function is merged into the existing power supply unit structure, utilizing the space already occupied by the power supply circuit components. This integration eliminates the need for additional space while maintaining the power failure continuity function.
