Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If external power source charging is implemented, then charging rate is improved, but energy management complexity increases
Solution Approach 1:
The patent introduces a virtual network as an intermediary communication layer that coordinates between the external power source, low voltage battery system, and high voltage battery system. This virtual network manages the complex energy flow relationships without requiring direct complex wiring or control connections between all components, thereby enabling high charging rates while managing system complexity.
Solution Approach 2:
The patent segments the battery system into two distinct voltage levels (low voltage and high voltage batteries) with separate control and monitoring. The external power source charges the low voltage battery, which then transfers energy to the high voltage battery through controlled energy transfer. This segmentation allows independent optimization of each subsystem while managing overall charging complexity.
2Reliability
If energy is supplied to all control modules during charging, then operational reliability is improved, but energy consumption increases
Solution Approach 1:
The patent implements dynamic energy distribution where control modules receive power selectively based on their operational status and charging phase. During external charging, the system dynamically adjusts which modules remain active versus entering low-power mode, ensuring critical functions maintain reliability while non-critical functions consume minimal energy. This dynamic adaptation resolves the contradiction between maintaining reliability and reducing energy consumption.
