Solution Overview

Problem

Existing generator systems face challenges in efficiently adapting to varying electrical loads, as they often require all components to be housed together, limiting flexibility and efficiency in power distribution.

Innovation Solution

A hybrid generator with detachable power units, comprising a separable engine module and inverter module, allowing for modular configuration and operation in different modes (quiet, maximum power, no generator, and hybrid) with a controller that manages power distribution based on load and battery capacity, and can be integrated into a wall panel for remote operation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If all generator components are housed together in a single unit, then the generator structure is simple and easy to manufacture, but the generator cannot efficiently adapt to varying electrical loads

Engineering Contradiction:
Improveadaptability to varying loadsVSAvoidgenerator structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The generator system is divided into separate modules: an engine module and an inverter module that can be detached from each other. The inverter module can alternatively be mounted in an electrical panel. This segmentation allows each module to be optimized independently and enables flexible configuration to adapt to varying load requirements.

Inventive Principle:
Principle #1Segmentation

2Power

If the generator operates at maximum power capacity, then it can meet high electrical demands, but it consumes excessive energy and generates unnecessary noise during low-demand periods

Engineering Contradiction:
Improvepower outputVSAvoidnoise and energy consumption
Core Design Contradiction:
PowerVSObject-generated harmful factors

Solution Approach 1:

The controller dynamically switches between different operating modes (quiet mode, maximum power mode, no generator mode, and hybrid mode) based on real-time load conditions and battery capacity. This dynamic adaptation allows the system to optimize power output while minimizing noise and energy consumption during low-demand periods.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system changes operational parameters by switching between different modes of operation. The controller adjusts the engine operation, battery discharge/charge states, and inverter output based on load requirements, enabling the generator to operate efficiently across a wide range of power demands rather than running at fixed maximum capacity.

Inventive Principle:
Principle #35Parameter changes

3Adaptability or versatility

If the generator is designed as a portable unit, then it provides flexibility in placement, but it cannot be integrated into wall panels for remote operation

Engineering Contradiction:
Improveintegration capabilityVSAvoidportability
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The inverter module is designed with dual mounting capabilities: it can be attached to the engine module for portable operation or mounted in an electrical panel for fixed, remote operation. This universal design allows the same component to serve multiple functions and deployment scenarios, providing both portability and integration capability.

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