Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a secondary memory device that is inexpensive and has a small volume, capable of providing continuous power supply when the primary power source is suddenly stopped, while also being compact and reliable.
Innovation Solution
A secondary memory device comprising a substrate with non-volatile memory, a control device, and a secondary battery that can supply power when the external power source is abnormal, along with a sensing device to detect power failures and a discharge switch to activate the secondary battery, all housed in separate but detachable components for safety and efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a super capacity is used for power supply when main power is stopped, then data continuity is ensured, but device volume and cost increase
Solution Approach 1:
The patent extracts the power supply function from the main device body and places it in a separate, removable battery module. This allows the battery to be removed and replaced independently, reducing the permanent volume required in the device while maintaining the backup power capability for data continuity.
Solution Approach 2:
The power supply system is segmented into a main power supply unit and a separate battery backup unit. The battery module is designed as an independent component that can be detached from the main device, allowing the device to function with minimal internal volume while still providing backup power capability when needed.
2Reliability
If a secondary battery is added for backup power, then power supply reliability is improved, but device complexity increases
Solution Approach 1:
The battery management functions are extracted into a separate control unit that operates independently from the main device logic. This dedicated control unit handles battery charging, discharging, and status monitoring, simplifying the overall system architecture by isolating battery-related complexity from the main device.
Solution Approach 2:
A control unit acts as an intermediary between the battery module and the main device. This intermediary manages the electrical connection and communication protocols, abstracting the complexity of battery integration from the main device while ensuring reliable power supply when needed.
3Object-affected harmful factors
If battery and substrate are in separate housings, then safety is improved, but device assembly complexity increases
Solution Approach 1:
The device is segmented into distinct housing compartments: one for the battery module and another for the substrate and main components. This physical separation prevents harmful effects from the battery (such as swelling or thermal issues) from affecting the electronic components, while standardized connection interfaces simplify the assembly process despite the separation.
Solution Approach 2:
While the battery and substrate are in separate housings, the design merges the power supply function into an integrated module that attaches to the main device body. The battery module combines the battery cell, protection circuitry, and connection interfaces into a single unit, simplifying assembly compared to separate component mounting.
