Solution Overview

Problem

Current standardized solutions for fast charging road and commuter ferries are inefficient due to time-consuming manual cable connections and limited high-amperage cable availability, which restricts energy transfer during brief turnaround periods.

Innovation Solution

Mechanical docking members with integrated electric connecting systems that automatically align and secure the vessel to the pier, allowing simultaneous mechanical and electric coupling, enabling rapid and stable high-current energy transfer.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If manual cable connections with plugs are used for shore power supply, then the connection can be made with standard flexible cables, but the connection procedure takes too much time and the power rating is limited

Engineering Contradiction:
Improveease of connectionVSAvoidconnection time
Core Design Contradiction:
Ease of manufactureVSLoss of time

Solution Approach 1:

The patent merges the mechanical docking function with the electrical connection function into a single integrated system. The electric connecting members are positioned on the vessel and pier such that they automatically align and connect during the mechanical docking process, eliminating the need for separate manual cable connection operations. This combination resolves the contradiction by achieving both ease of connection and reduced connection time.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The system enables self-service connection where the electrical contacts automatically engage with each other as the vessel docks mechanically. The alignment and connection of electric connecting members occur automatically during the docking process without requiring manual intervention, thus reducing connection time while maintaining ease of operation.

Inventive Principle:
Principle #25Self-service

2Power

If high amperage cables are used for fast charging, then the power transfer capability is increased, but the cables become large, heavy, and difficult to handle

Engineering Contradiction:
Improvepower ratingVSAvoidcable handling
Core Design Contradiction:
PowerVSEase of operation

Solution Approach 1:

The patent combines the mechanical docking structure with the electrical power transmission function. By integrating electric connecting members into the docking system, the patent achieves high power transfer capability through fixed, robust electrical contacts that are part of the docking infrastructure, eliminating the need for separate heavy-duty flexible cables that would be required to achieve the same power rating.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent replaces the flexible cable-based mechanical connection system with a fixed electrical contact system that is integrated into the docking structure. This substitution eliminates the need to manually handle heavy high-amperage cables while maintaining high power transfer capability through the fixed electrical connecting members.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Adaptability or versatility

If standardized flexible cable solutions are used, then the connection is simple and flexible, but the available high cross-section cables are limited and handling becomes complicated

Engineering Contradiction:
Improveconnection flexibilityVSAvoidcable handling complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent merges the docking mechanism with the electrical connection system, creating an integrated solution that provides both mechanical support and electrical power transfer. This integration eliminates the need for separate flexible cables while maintaining the adaptability of the docking system to handle various vessel types and power requirements.

Inventive Principle:
Principle #5Merging (Combining)
