Remote Notification Device for Ship Situational Awareness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display devices for ships require users to constantly monitor the device to grasp the surrounding situation, making it difficult to move around while maintaining situational awareness, as they need to frequently switch between visual confirmation and the device for information, especially when the user is not in front of the device.
Innovation Solution
An information remote notification device equipped with an orientation sensor, communicator, and notifier that allows users to visually confirm the situation while simultaneously receiving and understanding sensor information from an external terminal device, reducing user load and enabling situational awareness without constant device monitoring.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the display device is fixed at the steering position (bridge, command room), then the user can access the device, but the user must stay in front of the device to grasp the situation, making it difficult to move around
Solution Approach 1:
The system segments the information display function from the fixed display device by providing multiple portable terminal devices (smartphones, tablets) that can be carried by the user. Each terminal receives and displays sensor information independently, allowing the user to move freely while maintaining access to situational data.
Solution Approach 2:
The fixed display device acts as an intermediary that collects sensor data and distributes it to multiple portable terminals. This mediator approach allows the central system to remain stationary while enabling mobile access to information through the intermediary distribution network.
2Loss of information
If the user frequently switches between visual confirmation and the display device, then the user can gather information, but the confirmation process becomes inefficient and cumbersome
Solution Approach 1:
The system creates copies of the situational awareness information by transmitting sensor data to multiple portable terminals. Instead of the user returning to the original display device to check information, identical copies are available on mobile devices, eliminating the need to switch between locations and reducing confirmation time.
3Loss of information
If the display device displays all sensor information, then the user can grasp detailed information, but the device complexity and information processing load increase
Solution Approach 1:
The portable terminals serve multiple functions: they display sensor information, provide navigation guidance, and offer detailed information about detected objects. By making the terminals universal devices that handle multiple tasks, the system reduces the need for specialized equipment and simplifies the overall system architecture.

Function Achieved in This Case
The device allows users to intuitively grasp sensor information and situational details at a distance from the terminal device, reducing the need for constant attention and improving user-friendliness by providing timely and relevant information through vibration, sound, and light notifications.

AI summary
An information remote notification device is provided. The information remote notification device includes an orientation sensor configured to detect an oriented direction of the information remote notification device, a communicator configured to acquire sensor information from an external terminal device, and a notifier configured to notify the sensor information corresponding to the oriented direction detected by the orientation sensor. The sensor information is obtained by transmitting and receiving a detection signal and includes at least information obtained from a direction corresponding to the oriented direction detected by the orientation sensor.
