Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If multiple lithium-ion batteries are combined to achieve higher power supply capacity, then the power capacity increases, but the device complexity and infrastructure requirements increase due to separate charging and discharging lines
Solution Approach 1:
The patent combines separate charging and discharging lines into a single integrated line that can perform both functions. The H-bridge converter enables bidirectional power flow through the same physical connection, allowing the system to charge and discharge batteries without requiring separate infrastructure for each operation.
Solution Approach 2:
The H-bridge converter serves multiple functions: it acts as a charging converter when power flows from the utility to the batteries, and as a discharging converter when power flows from the batteries to the medical device. This multi-functionality eliminates the need for separate charging and discharging infrastructure.
2Power
If multiple batteries are physically connected and disconnected to scale power supply, then the power capacity can be adjusted, but the process is time consuming and interrupts operation
Solution Approach 1:
The patent enables continuous power supply during battery replacement by maintaining active H-bridge converters that can immediately take over power delivery. When one battery is replaced, other batteries continue supplying power through the same H-bridge converter, ensuring uninterrupted operation and eliminating downtime.
Solution Approach 2:
The system pre-configures multiple battery slots with batteries already connected to the H-bridge converter infrastructure. When a battery needs replacement, a standby battery is already in position and can be activated immediately, eliminating the need for time-consuming physical connections during the replacement process.
3Ease of operation
If separate charging and discharging lines are used for batteries, then charging and discharging can occur independently, but the system requires complex electrical infrastructure
Solution Approach 1:
The patent merges separate charging and discharging lines into a single integrated line with bidirectional capability. The H-bridge converter controls power flow direction electronically, allowing independent charging and discharging operations through the same physical infrastructure, thereby reducing electrical complexity.
4Power
If lithium-ion batteries are used with maximum capacity under air freight regulations, then shipping compliance is maintained, but higher power requirements cannot be met
Solution Approach 1:
The patent combines multiple compliant batteries (each under 100Wh) into a unified power system where the H-bridge converter aggregates their output. This allows the system to achieve higher total power capacity while each individual battery remains within air freight regulation limits.
Solution Approach 2:
The power system is segmented into multiple independent battery units, each compliant with air freight regulations. These segmented batteries work together through the H-bridge converter to provide cumulative power capacity that exceeds what a single battery could deliver, while maintaining regulatory compliance.
