Solution Overview
Problem
Current marine vessel hull manufacturing lacks a reliable method for embedding identification and tracking information within the hull structure, making it difficult to uniquely identify and monitor vessels during production and ownership transfer, and there is a need for real-time monitoring of exothermic foam setting processes to prevent damage during manufacturing.
Innovation Solution
Incorporating a wireless identification device between the outer hull layer and the inner liner of a marine vessel, which stores and transmits vessel identifiers, manufacturing information, and ownership details, and utilizing temperature sensors connected to these devices to monitor the foam setting process, ensuring safe handling and assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If thermocouples are used to monitor foam setting temperature, then the exothermic process can be tracked, but the complexity of the manufacturing process increases
Solution Approach 1:
The patent combines the wireless identification device with temperature monitoring capabilities into a single integrated unit. The wireless ID device includes a temperature sensor and memory that stores temperature data from the exothermic foam setting process, eliminating the need for separate thermocouple systems and reducing overall device complexity while maintaining reliable monitoring.
Solution Approach 2:
The wireless identification device serves multiple functions: it provides vessel identification, stores manufacturing information, and monitors temperature during foam setting. This multi-functional approach replaces multiple separate devices (identification tags, thermocouples, data loggers) with a single universal device, reducing complexity while improving reliability.
2Reliability
If wireless identification devices are embedded in the hull cavity, then vessel tracking information is securely stored, but the manufacturing process becomes more complex
Solution Approach 1:
The wireless identification device is placed in the hull cavity before the inner liner is permanently attached to the outer hull layer. This preliminary placement allows the device to be positioned and secured easily during assembly, avoiding the need for complex post-assembly installation procedures and reducing overall manufacturing complexity.
3Reliability
If temperature monitoring is implemented during foam setting, then damage prevention is improved, but the manufacturing time increases
Solution Approach 1:
The wireless identification device continuously monitors temperature during the exothermic foam setting process and stores this data in its memory. This feedback mechanism allows manufacturers to track the curing process in real-time, determine when the foam has adequately set based on temperature criteria, and proceed with handling without unnecessary waiting time, thus preventing damage while optimizing manufacturing time.
