Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional emergency light systems in marine vessels rely on cabled installations, which are time-consuming, prone to component wear, and complex, making them unreliable and costly for emergency situations.
Innovation Solution
A wireless mesh network-based emergency light control system that uses a communication interface for mesh networking, allowing emergency light modules to receive signals and operate autonomously during power outages, optimizing energy management and automation within the vessel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If cabled installation is used for emergency light control, then the system structure is stable, but the switching time increases and component wear occurs
Solution Approach 1:
The patent replaces the mechanical cabled installation with a wireless communication system. The emergency light control is achieved through wireless signals transmitted via antenna elements, eliminating physical cable connections. This substitution reduces switching time by removing mechanical relay operations and cable-based signal transmission delays, while maintaining system reliability through redundant wireless communication paths and error correction protocols.
2Reliability
If cabled installation is used for emergency light control, then the system is reliable, but device complexity and maintenance costs increase
Solution Approach 1:
The patent eliminates complex cabled installations by using wireless communication infrastructure. The control system comprises transmitting and receiving antennas, signal processors, and control units that communicate without physical cable connections. This reduces installation complexity significantly, as wireless systems require no cable routing through ship structures, no connection points, and no physical maintenance of cable joints and connectors.
3Ease of manufacture
If traditional emergency light system is used, then the system is established, but additional functions are complex and costly to add
Solution Approach 1:
The patent implements a universal wireless communication platform that can perform multiple functions. The same antenna elements and communication protocols used for emergency light control can also support navigation, safety monitoring, and other shipboard functions. The control units are programmed with flexible protocols that allow new functions to be added through software updates rather than hardware modifications, making the system highly adaptable and cost-effective for future expansions.
