Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If manual coupling and decoupling of electrical connectors is used, then the charging device can be simple in structure, but the operation becomes difficult and time-consuming

Engineering Contradiction:
Improvecharging device structureVSAvoidcoupling and decoupling operation
Core Design Contradiction:
Device complexityVSEase of operation

Solution Approach 1:

The charging connection device automatically performs coupling and decoupling operations without requiring manual intervention. The device uses sensors to detect the presence and position of the vessel, then autonomously navigates and connects the electrical connector to the counterpart connector on the vessel, eliminating the need for operating personnel to manually couple and decouple connectors.

Inventive Principle:
Principle #25Self-service

2Device complexity

If fixed-position electrical connectors are used, then the device structure can be simple, but the charging device cannot adapt to harsh weather conditions with vessel movement

Engineering Contradiction:
Improveconnector positioning systemVSAvoidweather condition adaptability
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The charging connection device incorporates dynamic positioning capabilities with multiple degrees of freedom, allowing the electrical connector to move and adjust its position in real-time. The system includes actuators and joints that enable the connector to compensate for vessel movements caused by waves and changes in water level, maintaining proper alignment and connection despite harsh weather conditions.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The device uses sensors and detection means to continuously monitor the position of the vessel and the counterpart electrical connector. This feedback information is used by the control system to adjust the connector's position and orientation, ensuring accurate alignment and maintaining connection stability even when the vessel moves due to weather conditions.

Inventive Principle:
Principle #23Feedback

3Ease of operation

If automated coupling mechanisms are implemented, then ease of operation improves, but the device complexity and safety risks increase

Engineering Contradiction:
Improvecoupling operationVSAvoidautomated mechanism complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The charging connection device is divided into multiple independent functional modules, including separate detection means for locating the vessel, positioning systems for adjusting connector location, and control systems for coordinating operations. This modular segmentation allows each subsystem to be optimized independently and simplifies maintenance while maintaining automated operation capabilities.

Inventive Principle:
Principle #1Segmentation
