Solution Overview

Problem

Existing high voltage component test systems are cumbersome to transport and set up, particularly in confined spaces, due to their size and weight, limiting their flexibility and accessibility for testing high voltage components like power transformers.

Innovation Solution

A modular test system with standard connecting elements, where system components are housed in lightweight, easily transportable cuboid containers that can be connected on-site to form a functional test system, allowing for flexible configuration and reduced weight through modular design and insulation measures.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If test systems are integrated in freight containers, then protection during transport is improved, but the size and weight make them difficult to transport to test sites

Engineering Contradiction:
Improveprotection during transportVSAvoidweight of test system
Core Design Contradiction:
ReliabilityVSWeight of moving object

Solution Approach 1:

The test system is divided into multiple separate transport containers, each housing individual system components (inverter, HV filter, control units). This segmentation reduces the weight of each container to portable levels (100-200kg) while maintaining protection during transport. The containers can be separately transported and assembled on-site.

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If test systems are transported as loose components, then flexibility in assembly is improved, but the setup complexity increases

Engineering Contradiction:
Improveflexibility in assemblyVSAvoidsetup complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

System components are pre-mounted and pre-configured within standardized transport containers before arrival at the test site. Electrical connections and mechanical mounting positions are prepared in advance, reducing on-site assembly complexity while maintaining flexibility in configuration.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

Standardized transport containers serve multiple functions: they protect components during transport, provide mounting structures at the test site, and enable flexible reconfiguration. The same container structure is used for different system components, simplifying logistics and setup.

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

3Weight of moving object

If system components are made portable, then transportability is improved, but the weight limit restricts the voltage range

Engineering Contradiction:
Improveportability of containerVSAvoidvoltage range
Core Design Contradiction:
Weight of moving objectVSAdaptability or versatility

Solution Approach 1:

The test system for higher voltage ranges is segmented into multiple portable container modules that can be combined. Individual containers remain within portable weight limits, but the system as a whole can handle higher voltages through the coordinated operation of multiple modules.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Multiple portable container modules are combined on-site to create a test system capable of handling higher voltage ranges. The inverter modules and other components work together in parallel or series configurations to achieve the required voltage and power levels while maintaining portability.

Inventive Principle:
Principle #5Merging (Combining)
