Movable Sensor for Underwater Vehicle Position Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems fail to stably and continuously detect the position of underwater vehicles and their mother ships due to limited detection ranges and environmental changes, making it difficult to monitor their movements and relationships within exclusive economic zones or important harbors.
Innovation Solution
A vehicle position notification apparatus with a movable detection unit that adheres to and tracks underwater vehicles and mother ships using sensors, thrusters, and communication units, transmitting position information periodically or intermittently, and includes a mobility inhibition mechanism to deter movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a fixed sensor is installed on a warship or helicopter to detect underwater vehicles, then the detection capability is provided, but the detection range is limited and stable continuous detection cannot be achieved
Solution Approach 1:
The sensor is mounted on a floating object that moves with water currents rather than being fixed on a warship or helicopter. This dynamic positioning allows the sensor to cover a larger detection area while maintaining stable detection capabilities, as the floating object naturally drifts within the detection range.
Solution Approach 2:
A floating object serves as an intermediary carrier for the sensor, separating the sensor from direct mounting on warships or helicopters. This intermediary approach enables the sensor to be positioned optimally in the water column while being passively transported by currents, expanding detection coverage without requiring active pursuit mechanisms.
2Duration of action of stationary object
If multiple sensors are used to detect moving underwater vehicles, then continuous detection can be achieved, but the system complexity and cost increase
Solution Approach 1:
Instead of deploying multiple fixed sensors that require complex coordination, a single sensor mounted on a floating object naturally achieves continuous detection by drifting with water currents. The dynamic movement of the floating object provides temporal coverage that would otherwise require multiple spatially distributed sensors.
Solution Approach 2:
The floating object utilizes natural water currents for its own movement and positioning, eliminating the need for active propulsion systems or complex control mechanisms. This self-service approach allows continuous detection without requiring multiple sensors or complex multi-sensor coordination systems.
3Measurement precision
If sensors are used to detect underwater vehicles, then position information can be obtained, but the ability to inhibit movement of detected targets is lost
Solution Approach 1:
The floating object acts as an intermediary that can physically interact with detected underwater vehicles. When a target is detected, the floating object can be directed to approach and make contact with the target, providing a passive but effective means to inhibit target movement without requiring active pursuit by warships.
