Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If rechargeable batteries are used in cartridge batteries to enable multiple charges, then the number of times electric power can be supplied increases, but the reliability decreases due to performance degradation from repeated charging and discharging
Solution Approach 1:
The management device performs preliminary assessment of battery chargeability before allowing charging operations. By evaluating battery status in advance and determining optimal charging conditions, the system prevents charging when the battery is in a vulnerable state, thereby avoiding performance degradation while still enabling multiple charge cycles throughout the battery's lifespan.
2Ease of operation
If the cartridge battery structure is adopted to enable easy replacement, then the ease of operation increases, but the reliability decreases due to potential connection issues between the cartridge battery and electrically powered device
Solution Approach 1:
The management device continuously monitors the connection status between the cartridge battery and the electrically powered device. By providing real-time feedback on connection quality, the system can detect potential issues before they cause failures and prompt users to reseat or replace the battery, thereby maintaining reliable connections while preserving the ease of replacement inherent in the cartridge design.
3Productivity
If centralized management device is implemented to monitor and manage battery usage, then the productivity of battery system increases through optimized charging, but the device complexity increases
Solution Approach 1:
The battery pack includes an integrated controller that autonomously manages its own charging process by communicating with the management device. This self-service capability allows the battery to report its own status, receive charging instructions, and execute charging operations independently, thereby achieving centralized management benefits without requiring complex external monitoring systems for each battery parameter.
