1Power

If multiple portable generators are used together to supply higher demand loads, then power capacity is improved, but technical and safety problems increase

Engineering Contradiction:
Improvepower capacityVSAvoidtechnical and safety problems
Core Design Contradiction:
PowerVSReliability

Solution Approach 1:

The system divides the power generation function into separate modular units, each with its own generator set and battery bank. These modules can be independently deployed and scaled to meet power demands without the technical complications of paralleling multiple traditional generators.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

A central control system acts as an intermediary between multiple battery banks and the load, coordinating power distribution and managing battery charger sharing. This mediator enables reliable operation by centrally managing the complexity of multiple power sources.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If a single portable generator is used, then technical and safety problems are reduced, but power capacity is limited

Engineering Contradiction:

Solution Approach 1:

Multiple battery-powered generator modules are merged into a coordinated system that functions as a unified power source. The modules share battery chargers and operate under centralized control, combining their individual capacities to deliver high power while maintaining the simplicity and safety of battery-based operation.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

Each module is designed as a universal unit that can independently provide power generation and battery charging functions. The battery chargers can serve multiple battery banks, and the control system can manage various operational modes, making the system adaptable to different power capacity requirements.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Power

If multiple battery banks are used in separate modules, then power capacity and redundancy are improved, but system complexity increases

Engineering Contradiction:

Core Design Contradiction:
PowerVSDevice complexity

Solution Approach 1:

The battery chargers are designed as universal resources that can charge multiple battery banks interchangeably. This multi-functionality allows the system to manage multiple power storage units without proportionally increasing charging infrastructure complexity.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The central control system continuously monitors the state of charge and operational status of all battery banks and chargers, using feedback signals to dynamically allocate charging resources and coordinate power distribution, thereby simplifying the management of multiple energy storage units.

Inventive Principle:
Principle #23Feedback

4Productivity

If battery charger sharing is implemented between modules, then resource utilization is improved, but control complexity increases

Engineering Contradiction:
Improveresource utilizationVSAvoidcontrol complexity
Core Design Contradiction:

Solution Approach 1:

The central control system serves as an intermediary that manages battery charger sharing between modules. It receives requests from various modules and allocates charger resources optimally, handling the control complexity centrally while allowing individual modules to remain relatively simple.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The battery charger allocation is dynamically adjusted based on real-time system conditions, such as charge state of battery banks and power demands. The control system can flexibly reassign chargers between modules as needs change, optimizing resource utilization without requiring complex permanent interconnections.
