Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Duration of action of moving object

If traditional combustion-based UPS systems are used to provide backup power, then the system can operate for extended durations by adding fuel, but the system cannot respond to massive power fluctuations occurring in tenths of hundredths of a second

Engineering Contradiction:

Improveoperation timeVSAvoidresponse time

Core Design Contradiction:

Duration of action of moving objectVSSpeed

Solution Approach 1:

The system divides the power supply function into two separate modules: a combustion-based generator for long-duration power supply and a battery-based ESS for rapid response to power fluctuations. This segmentation allows each module to optimize for its specific function without compromise.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent combines two different power generation technologies (combustion generator and battery ESS) into a single integrated system that can leverage the strengths of both: extended operation duration from the generator and rapid response capability from the battery system.

Inventive Principle:

Principle #5Merging (Combining)

2Power

If traditional motor/engine-based UPS systems are deployed in areas without proper load balancing, then the system can provide power supply, but noise occurs in power generation for 3-phase AC motors and load balancing cannot be maintained

Engineering Contradiction:

Improvepower supply capabilityVSAvoidelectrical noise and load imbalance

Core Design Contradiction:

PowerVSObject-affected harmful factors

Solution Approach 1:

The battery-based ESS acts as an intermediary between the combustion generator and the electrical loads. It buffers and conditions the power, filtering out noise and maintaining load balance before delivering power to the 3-phase AC motors and other sensitive equipment.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The system replaces the mechanical motor/engine-based power generation with an electronic battery-based ESS that can provide precise electrical control and conditioning, eliminating the mechanical noise and load balancing issues inherent in traditional systems.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Power

If traditional UPS systems are used, then they can provide backup power, but they cannot separate power production device from energy storage device

Engineering Contradiction:

Improvepower generation capabilityVSAvoidsystem configuration flexibility

Core Design Contradiction:

PowerVSAdaptability or versatility

Solution Approach 1:

The system separates power production (combustion generator) from energy storage (battery ESS), allowing each component to be independently sized, configured, and optimized for its specific function while maintaining overall system flexibility.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The modular architecture allows the system configuration to dynamically adapt to different power and energy storage requirements by adjusting the relative sizes and capacities of the generator and battery components based on specific application needs.
