Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If no test apparatus is provided for the vehicle on-board controller, electromagnet controller, and electromagnet, then the system complexity is reduced, but the reliability of the magnetic levitation train cannot be ensured due to inability to perform effective testing

Engineering Contradiction:
Improvereliability of magnetic levitation trainVSAvoidcomplexity of test apparatus
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The test apparatus is divided into multiple independent test beds: vehicle on-board controller test bed, electromagnet controller test bed, and electromagnet test bed. Each test bed can independently test specific components, allowing modular testing without requiring a completely integrated complex system. This segmentation enables reliable testing of individual components while maintaining manageable system complexity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The test apparatus is designed with multi-functional capabilities where each test bed can perform multiple testing functions. For example, the electromagnet controller test bed can test different electromagnet controllers under various simulated conditions. This universality allows a single test bed to replace multiple specialized devices, improving reliability through comprehensive testing while controlling overall device complexity.

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

2Reliability

If a comprehensive test apparatus is constructed to test all components, then the reliability improves through effective testing, but the device complexity and cost increase significantly

Engineering Contradiction:
Improvefunctional verification capabilityVSAvoidcomplexity of integrated test system
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The comprehensive testing capability is achieved through segmented test beds rather than a single monolithic system. Each test bed focuses on specific components (vehicle controller, electromagnet controller, electromagnet) and can be independently configured and maintained. This approach provides functional verification of all components while keeping individual test bed complexities manageable and allowing parallel operation of multiple simpler test beds.

Inventive Principle:
Principle #1Segmentation

3Reliability

If components are tested separately without joint testing, then the testing process is simpler, but the failure rate increases due to lack of integrated system verification

Engineering Contradiction:
Improvefailure rate reductionVSAvoidcomplexity of joint testing system
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The testing system is segmented into independent but complementary test beds that can operate separately for component-level testing or be integrated for joint system testing. This allows the system to provide both simple individual component verification and complex integrated system verification, reducing failure rates through comprehensive testing while maintaining flexibility in testing complexity based on requirements.

Inventive Principle:
Principle #1Segmentation

AI summary

A magnetic levitation test system and an electromagnet test method. A vehicle-mounted controller (1024), an electromagnet controller, and an electromagnet are subjected to joint test by means of the magnetic levitation test system integrated with a vehicle-mounted controller test bed (102), an electromagnet controller test bed (104), and an electromagnet test bed (106). The running condition of a train can be simulated, and the vehicle-mounted controller (1024), the electromagnet controller, and the electromagnet are subjected to joint test under the simulated running condition of the train. Therefore, the vehicle-mounted controller (1024), the electromagnet controller, and the electromagnet are subjected to function verification, thereby reducing the fault rate when the vehicle-mounted controller (1024), the electromagnet controller, and the electromagnet are used at the same time.
