Waterproof Electrical Connector for Removable Watercraft Electronics
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Watercraft electronics face challenges when exposed to harsh environments, as traditional waterproofing methods fail when components need to be removed or replaced, risking damage from fluids and debris.
Innovation Solution
A watercraft design featuring a waterproof electronics container mechanically coupled to a strut, with replaceable conductor elements and seals, allowing for safe disconnection and reconnection of electrical components in wet conditions without compromising the components or the watercraft.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If electrical equipment is sealed in watertight compartments, then waterproofing is improved, but accessibility for removal and replacement deteriorates
Solution Approach 1:
The electrical equipment is divided into modular components that can be independently removed and replaced. The connector is split into two separate parts (plug and receptacle) that can be disconnected without opening the watertight compartment, allowing battery replacement while maintaining the sealed enclosure.
Solution Approach 2:
A waterproof connector system acts as an intermediary between internal electrical components and external wiring. This connector includes sealing elements that maintain watertight integrity during connection and disconnection operations, enabling component replacement without compromising the waterproof barrier.
2Ease of repair
If electrical components are disconnected in wet environments, then replacement is enabled, but damage from fluids and debris worsens
Solution Approach 1:
The connector is designed with pre-positioned sealing elements and alignment features that ensure proper engagement before connection. The sealing surfaces are prepared in advance to prevent fluid ingress during the connection process, allowing safe disconnection and reconnection in wet environments.
Solution Approach 2:
The connector includes protective sealing elements that are already in place before disconnection occurs. These seals create a protective barrier that prevents fluids and debris from entering the connector interfaces during removal and reinstallation operations.
3Productivity
If connectors are made reusable, then productivity is improved, but wear and deterioration worsen
Solution Approach 1:
The connector is designed with replaceable wear components such as sealing elements and contact surfaces. When wear occurs, only the damaged components need to be replaced rather than the entire connector assembly, extending the overall system life while maintaining reusability for repeated connections.

AI summary
A watercraft and a waterproof electronics container are provided. The watercraft includes a flotation portion. A strut is removably affixed to a portion of the watercraft. A first connector portion is mounted to the upper end of the strut. A waterproof electronics container includes a second connector portion is disposed such that the second connector forms at least one electrically conductive pathway with the first connector portion when both are affixed to the watercraft. The waterproof electronics container is removably affixed to the said watercraft. In one aspect, the waterproof electronics container houses a power source capable of powering an electric motor that propels the watercraft.
