Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical systems in small watercraft and recreational vehicles face challenges such as limited space, difficulty in controlling electrical components without disrupting the water-tight integrity of the vessel, and inefficient power distribution, especially when remote control is desired.
Innovation Solution
A digital switching system with a solid state relay switch bank and microcontroller unit (MCU) reduces the control panel footprint by using a single communication cable, allowing for remote control via Bluetooth or WiFi, and incorporates water-tight receptacles for power outlets.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional electrical distribution systems are installed in small watercraft, then electrical functionality is provided, but space is consumed and wiring complexity increases
Solution Approach 1:
The patent combines multiple electrical functions (power distribution, control, communication) into a single integrated control panel unit. The digital switching device integrates multiple relay switches and control circuits into one compact module, reducing the overall space required for electrical systems in the watercraft.
Solution Approach 2:
The control panel is designed as a universal unit that can handle multiple electrical functions simultaneously - power distribution to various outlets, remote control operations, and communication with the vessel's systems. This multi-functional approach eliminates the need for separate dedicated systems for each function, optimizing space utilization.
2Volume of moving object
If control panels are made compact to save space, then space is conserved, but control accessibility and operation become difficult
Solution Approach 1:
The patent introduces wireless remote control capability that operates in the spatial dimension outside the physical control panel. The remote control device transmits signals wirelessly to the digital switching device, allowing the operator to control electrical functions from any position within the vessel without needing to physically access the compact control panel.
Solution Approach 2:
The wireless communication system acts as an intermediary between the operator and the control panel. The remote control device and digital switching device communicate through wireless signals, mediating the control function and eliminating the need for direct physical interaction with the compact control panel interface.
3Adaptability or versatility
If wires are run through the vessel interior for power distribution, then electrical connectivity is achieved, but the vessel's water-tight integrity is compromised
Solution Approach 1:
The patent extracts the electrical control functions from the vessel's structural interior by mounting the control panel and digital switching device on the interior surface of the hull. This positioning allows the electrical system to operate independently without penetrating the hull structure, thereby maintaining water-tight integrity while achieving full electrical connectivity through the hollow interior space.
4Use of energy by moving object
If multiple batteries are carried to extend power supply, then power capacity increases, but weight and space increase
Solution Approach 1:
The digital switching device dynamically manages power distribution to various electrical outlets based on operational needs. The system can selectively activate or deactivate power to different circuits, allowing the existing battery to be used more efficiently. This dynamic power management extends the effective power capacity without requiring additional battery weight.

AI summary
An electrical distribution system for personal water craft. The primary components include a digital switching device; a series of power lines; and one or more remote controls, a control panel, or both. The digital switching device is preferably a bank of solid state relay switches controlled by an MCU. The control panel also has an MCU. The control panel MCU communicates with the digital switching device MCU. This allows signals from the control panel to travel on a single communication cable to the digital switching device, significantly reducing the control panel footprint compared to prior art control panels. When a radio frequency (RF) receiver is provided, the electrical distribution system may receive signals from a remote control. The remote control may be utilized in addition to or in lieu of the control panel. Power lines run from the digital switching device to wherever power is desired in the vessel.
