Marine Vessel Wake Network for Low-Power Device Activation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for controlling powered devices on marine vessels consume excessive power due to constant power consumption in low power or sleep states, especially with the integration of wireless authentication systems, which complicates control and increases power demand.
Innovation Solution
A low energy system utilizing a communication network with both CAN bus and 12 VDC signals for waking powered devices, allowing them to remain in a sleep state until authorized, thereby reducing power consumption and incorporating redundancy through separate wake mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If powered devices remain constantly powered on or in low power state, then system functionality is maintained, but power consumption increases
Solution Approach 1:
The system performs preliminary authentication through wireless key recognition before activating powered devices. The controller authenticates the wireless key in advance, and only after successful authentication does it send the wake-up signal to activate the powered device, ensuring both power savings and system reliability
Solution Approach 2:
The powered devices dynamically transition between sleep state and wake state based on authentication results. When no authentication is detected, devices remain in sleep state to conserve power; when authentication succeeds, devices wake up to perform functions, achieving adaptive power management
2Adaptability or versatility
If wireless authentication systems are integrated, then control capability is enhanced, but device complexity and power demand increase
Solution Approach 1:
The system introduces a wireless key as an intermediary authentication medium between the user and the powered device. The wireless key stores authentication information and communicates with the controller, providing enhanced control capability while keeping the overall system architecture relatively simple through this intermediary element
Solution Approach 2:
The controller performs multiple functions: it manages powered device activation, processes wireless key authentication, and sends wake-up signals. This multi-functionality reduces the need for separate dedicated components, thereby enhancing control capability without proportionally increasing system complexity
3Reliability
If multiple wake mechanisms are implemented, then system reliability is improved, but device complexity increases
Solution Approach 1:
The system implements preliminary authentication through wireless key recognition before activation. The controller checks the wireless key in advance, and only after successful authentication does it proceed to send the wake-up signal, ensuring reliable activation while maintaining a clear sequential control flow
Solution Approach 2:
The system uses feedback from the wireless key authentication process to determine whether to activate the powered device. The controller receives authentication feedback from the wireless key, and based on this feedback, it decides whether to send the wake-up signal, improving reliability through feedback-based control

AI summary
A low energy system for waking a powered device of a marine vessel from a sleep state to a wake state. The low energy system includes a communication network configured for communicating a signal for waking the powered device. The low energy system further includes a controller electrically coupled to the powered device, the controller having a sleep state and a wake state. The controller is configured to receive the signal within the communication network. The controller is configured to wake from the sleep state thereof and to wake the powered device from the sleep state thereof when the signal is received. The controller being in the sleep state thereof before the signal is received conserves power for the marine vessel.
