Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If a single power source charges multiple battery submodules simultaneously, then charging efficiency and system integration are improved, but it becomes difficult to provide battery-specific charging parameters and maintain uniform charge across all batteries

Engineering Contradiction:

Improvecharging efficiencyVSAvoidbattery-specific charging parameters

Core Design Contradiction:

ProductivityVSAdaptability or versatility

Solution Approach 1:

The system segments the charging process by providing each battery submodule with its own dedicated power converter that can be independently controlled. This allows the single power source to be divided into multiple independent charging channels, each capable of delivering battery-specific parameters while maintaining overall charging efficiency.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Each battery submodule receives customized charging parameters (voltage, current, temperature control) tailored to its specific state and requirements. The local quality principle enables different parts of the system (individual batteries) to have different charging characteristics rather than a uniform approach, solving the adaptability problem.

Inventive Principle:

Principle #3Local quality

2Device complexity

If multiple battery submodules are charged with equal power distribution, then system simplicity is maintained, but battery health and charge uniformity deteriorate due to varying optimal charging parameters

Engineering Contradiction:

Improvepower distribution systemVSAvoidbattery health

Core Design Contradiction:

Device complexityVSReliability

Solution Approach 1:

The power distribution system dynamically adjusts charging parameters for each battery submodule based on real-time monitoring of battery state (charge level, temperature, health status). This dynamic adaptation allows the system to maintain simplicity in structure while achieving optimal battery health through continuous parameter optimization.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system implements feedback control by monitoring battery metrics and using this information to adjust charging parameters in real-time. This closed-loop control ensures that each battery receives appropriate charging power to maintain health and charge uniformity, preventing the reliability deterioration that would occur with equal power distribution.

Inventive Principle:

Principle #23Feedback

3Reliability

If custom charging parameters are determined for each battery submodule, then battery health and recharging speed are optimized, but system complexity and control requirements increase

Engineering Contradiction:

Improvebattery healthVSAvoidcharger interface and control system

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The charger interface is designed as a universal control system that can manage multiple battery submodules with different parameters through a single integrated platform. This multi-functional design reduces overall system complexity by consolidating control functions rather than requiring separate control systems for each battery.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

Each battery submodule is equipped with monitoring capabilities that automatically report its state to the charger interface, reducing the burden on the control system. The batteries essentially self-report their needs, allowing the charger interface to automatically determine and apply appropriate charging parameters without complex manual intervention.

Inventive Principle:

Principle #25Self-service

AI summary

Embodiments of the invention are directed to methods and systems for providing electric power with individualized charging parameters to each battery in a multi-battery system. Electric power from the single power source can be distributed in a controlled and unequal manner. Custom charging parameters can be designed for each battery. The custom charging parameters can be determined based on battery metrics gathered for that battery, and can be designed to optimize for a number of suitable priorities, such as recharging speed and battery health. As a result, each battery can be recharged according to individual needs.
