Solution Overview
Problem
Existing systems fail to accurately detect and respond to load loss from machines like haul trucks and ships, especially when loads are lost through intended openings or in environments where water displacement methods are unreliable, leading to inefficiencies and potential hazards.
Innovation Solution
An automated load response system that includes sensors to detect load loss using a detection beam and a controller to analyze signals, providing warnings and location information, and allowing for accurate determination of lost load quantity and geographical location, with the ability to alert operators and external systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If water displacement methods are used to detect cargo loss, then the system can detect cargo leaving a ruptured hull, but the determination is inaccurate because additional factors not accounted for may affect buoyancy
Solution Approach 1:
The patent replaces the mechanical buoyancy-based detection system with an optical sensing system that uses light detection and ranging (LIDAR) technology. The sensor emits laser pulses and detects the reflected light from lost cargo, providing accurate measurement independent of water displacement factors.
Solution Approach 2:
The patent introduces an optical intermediary (laser beam) between the detection system and the lost cargo. This intermediary allows for precise measurement of cargo location and quantity without being affected by water displacement or buoyancy changes.
2Productivity
If the system provides detailed location and quantity information of lost loads, then cleanup and salvage operations can be arranged efficiently, but the device complexity increases
Solution Approach 1:
The patent designs a multi-functional sensor system that simultaneously performs multiple tasks: detecting lost cargo, determining its location, calculating quantity, and providing real-time alerts. This universal system replaces multiple separate devices that would otherwise be needed for each function.
Solution Approach 2:
The system automatically processes raw sensor data through integrated algorithms that calculate cargo location and quantity without requiring external intervention. The controller self-manages the entire detection and analysis process, reducing operational complexity.
