Solution Overview

Problem

Containerized power supply systems with multiple generators face challenges in fitting multiple drive units and associated components within a limited ISO container footprint, particularly in terms of access and efficient operation.

Innovation Solution

A staggered or offset arrangement of drive units and exhaust systems within the container, combined with modular components and ventilation/cooling systems, allows for efficient power generation and maintenance access within a compact footprint.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Power

If multiple drive units and generators are packed into a standard ISO container to achieve higher power operation, then power output capability is improved, but access to drive units for checking, servicing and repair becomes difficult

Engineering Contradiction:
Improvepower output capabilityVSAvoidaccess to drive units
Core Design Contradiction:
PowerVSEase of repair

Solution Approach 1:

The patent applies dimensional arrangement by positioning drive units at different longitudinal positions within the container (staggered arrangement along the length of the container). This spatial distribution in one dimension (longitudinal axis) allows maintenance personnel to access drive units from the ends of the container, resolving the contradiction between packing density and accessibility.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Volume of moving object

If multiple drive units are arranged in a compact configuration within the container, then space utilization is improved, but assembly and maintenance complexity increases

Engineering Contradiction:
Improvespace utilizationVSAvoidassembly and maintenance complexity
Core Design Contradiction:
Volume of moving objectVSDevice complexity

Solution Approach 1:

The patent segments the container into distinct longitudinal zones, each housing a drive unit and its associated generator. This segmentation allows each subsystem to be independently accessed, assembled, and maintained, reducing overall complexity despite the multi-unit configuration.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

By arranging drive units along the longitudinal dimension of the container rather than stacking them in a compact block, the patent reduces assembly and maintenance complexity while still achieving efficient space utilization within the container volume.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Productivity

If drive units are positioned to maximize power generation capacity, then productivity is improved, but operational access and serviceability deteriorates

Engineering Contradiction:
Improvepower generation capacityVSAvoidoperational access
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

The patent positions drive units at different longitudinal positions within the container, creating a staggered arrangement that maximizes power generation capacity while maintaining operational access. This dimensional distribution allows operators to reach each drive unit from the container ends without disrupting other components.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)
