RV Power Distribution With Dual Junction Box Isolation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing recreational vehicles face challenges in efficiently managing power distribution and communication between different subsystems, leading to inefficiencies and safety risks, particularly when electrical issues arise with the RV power subsystem.
Innovation Solution
The implementation of a dual electrical junction box system, a central controller, and protocol translators to facilitate communication among various subsystems, allowing for independent operation of the RV power subsystem while maintaining functionality of the chassis power subsystem, and enabling communication across different protocols.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single electrical junction box is used for both chassis power subsystem and RV power subsystem, then device complexity is reduced, but reliability deteriorates when electrical issues arise in the RV power subsystem
Solution Approach 1:
The patent divides the electrical junction box into two separate units: a first electrical junction box for the chassis power subsystem and a second electrical junction box for the RV power subsystem. This segmentation allows independent operation and fault isolation, so that electrical issues in the RV power subsystem do not affect the chassis power subsystem, thereby resolving the reliability concern while maintaining manageable device complexity through modular design.
2Adaptability or versatility
If protocol translators are implemented for communication between subsystems, then adaptability improves across different communication protocols, but device complexity increases
Solution Approach 1:
The patent introduces protocol translators as intermediary devices that facilitate communication between different subsystems using different communication protocols. The first protocol translator enables communication between the chassis power subsystem and the central controller, while the second protocol translator enables communication between the RV power subsystem and the central controller. This intermediary approach allows the system to support multiple communication protocols without requiring direct integration between all components, thereby improving adaptability while managing device complexity through standardized intermediary interfaces.

AI summary
A recreational vehicle includes a power source, a first electrical junction box, a second electrical junction box, a chassis power subsystem, and a recreational vehicle (RV) power subsystem. The first electrical junction box is electrically coupled between the power source and the second electrical junction box, the first electrical junction box is electrically coupled between the power source and the chassis power subsystem, and the second electrical junction box is electrically coupled between the first electrical junction box and the RV power subsystem.
