Innovation Solution
The device determines storage processing based on battery temperature and level, switching to high-speed storage when power is low to ensure data safety and continuity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If battery level monitoring is implemented with alarm signals, then power status awareness is improved, but data loss occurs when battery power becomes insufficient
Solution Approach 1:
The system performs preliminary actions by storing diagnostic data in the high-speed storage unit before power failure occurs. When battery level drops below a threshold, the system automatically saves ongoing diagnostic data to the high-speed storage unit, ensuring data safety without requiring user intervention or waiting for shutdown completion.
Solution Approach 2:
The invention provides beforehand cushioning by implementing a high-speed storage unit that acts as a safety buffer. This storage unit receives and preserves diagnostic data even when the main battery power becomes insufficient, cushioning against the harmful effect of data loss during power failure scenarios.
2Productivity
If conventional storage processing is used, then device complexity is reduced, but processing interruptions occur when battery power is insufficient
Solution Approach 1:
The storage system is segmented into two distinct parts: a conventional storage unit for normal operation and a high-speed storage unit for critical data preservation. This segmentation allows the system to maintain simple conventional storage during normal operation while adding high-speed storage capacity only when needed during power failure, thus managing complexity effectively.
Solution Approach 2:
The high-speed storage unit acts as an intermediary between the main battery power system and the diagnostic data. It receives data from the conventional storage processing and preserves it independently when power becomes insufficient, mediating the transition and ensuring processing continuity without requiring complete system redesign.
3Productivity
If data transfer is performed continuously, then productivity is improved, but data loss increases when battery power becomes insufficient
Solution Approach 1:
The system performs preliminary data storage actions in the high-speed storage unit before power failure interrupts data transfer. When battery level drops below the threshold, the system automatically saves ongoing transfer data to the high-speed storage unit, ensuring data safety without interrupting the overall data transfer workflow or requiring user intervention.

AI summary
A mobile ultrasonic diagnostic device comprising: a battery (30); a storage processing unit (38) that performs storage processing of data used by the mobile ultrasonic diagnostic device; a high-speed storage unit (80) that performs storage processing faster than the storage processing unit (38); and a storage processing determination unit (36) that determines the storage processing on the basis of the temperature or remaining power of the battery (30). Data can be safely used without loss even when there is the possibility that power cannot be supplied from the battery, as a result of the storage processing unit (38) and the high-speed storage unit (80) performing storage processing on the basis of the storage processing determined by the storage processing determination unit (36).
