Innovation Solution

A distributed power control system using multiple versatile power distribution modules connected via a CAN network, allowing intelligent power routing and control of various loads, including ballast, trim tabs, and navigation lights, with modules positioned strategically across the boat to simplify wiring and enhance communication between helm, speed monitoring, and engine control modules.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a traditional power distribution system with extensive wiring is used, then all necessary loads can be powered, but the system becomes complex and difficult to maintain

Engineering Contradiction:

Improvesystem reliabilityVSAvoidwiring complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The power distribution system is divided into multiple intelligent power distribution modules (IPDMs) distributed throughout the watercraft. Each module independently manages power for specific loads, eliminating the need for extensive central wiring. This segmentation reduces wiring complexity while maintaining system reliability through distributed architecture.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent replaces the mechanical wiring system with a communication network (CAN bus) connecting the IPDMs. Instead of using extensive physical wiring to control loads, the system uses digital communication signals to transmit control commands, significantly reducing wiring complexity while improving reliability.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Adaptability or versatility

If the power distribution system is made more flexible and reconfigurable, then adaptability to customer demands improves, but system complexity increases

Engineering Contradiction:

Improvesystem adaptabilityVSAvoidcontrol system complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

Each IPDM is designed as a universal module capable of controlling multiple different types of loads (ballast pumps, trim tabs, navigation lights, etc.). The modules can be configured through software to perform different functions based on customer requirements, providing high adaptability without increasing physical system complexity.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The power distribution system employs dynamic reconfiguration capabilities where IPDMs can be programmatically assigned to control different loads based on operational modes or customer preferences. This dynamic adaptability allows the system to respond to varying demands without requiring physical reconfiguration or additional complex hardware.

Inventive Principle:

Principle #15Dynamics

3Adaptability or versatility

If extensive wiring is used to power all loads, then all functions can be implemented, but maintenance and troubleshooting become more difficult

Engineering Contradiction:

Improvefunctional capabilityVSAvoidtroubleshooting ease

Core Design Contradiction:

Adaptability or versatilityVSEase of repair

Solution Approach 1:

The IPDMs incorporate self-diagnostics and monitoring capabilities that automatically detect and report faults in the power distribution system. Each module can identify issues with connected loads and communicate problem locations through the CAN network, enabling rapid troubleshooting without requiring extensive manual inspection of wiring throughout the watercraft.

Inventive Principle:

Principle #25Self-service

4Ease of operation

If a centralized power control system is used, then control is simplified, but electrical noise and fire risks increase

Engineering Contradiction:

Improvecontrol simplicityVSAvoidelectrical noise and fire risks

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

By distributing power control functions across multiple IPDMs throughout the watercraft, the system reduces the concentration of electrical currents in a single location. This segmentation lowers fire risks by preventing overheating at centralized connection points and reduces electrical noise through distributed signal processing rather than centralized handling.

Inventive Principle:

Principle #1Segmentation
