Electromagnetic Vehicle And Cargo Locking For Authorized Release
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Inadvertent, unauthorized, and/or unexpected movement of vehicles and cargo poses safety risks and asset loss due to inadequate control mechanisms, particularly in environments like airports and cargo ships, where environmental factors and operational pressures lead to unintended release of parking brakes or incorrect cargo handling.
Innovation Solution
A locking system utilizing an electromagnetic locking arrangement with electromagnets to selectively attract and lock vehicles or cargo in position, controlled by a remote power supply and override system, ensuring secure immobilization until authorized movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a parking brake system is operated by aircrew, then the aircraft can be held in position, but the aircraft may be released inadvertently or without authorization
Solution Approach 1:
The patent replaces the manual mechanical parking brake system with an electromagnetic locking arrangement. Electromagnets are positioned to engage with ferromagnetic materials on the aircraft wheels, providing automated magnetic locking instead of manual brake application. This substitution eliminates the need for aircrew to manually operate brakes while maintaining reliable position control through centralized automated control.
Solution Approach 2:
The patent introduces an intermediary electromagnetic locking system between the aircrew and the aircraft movement control. The electromagnetic arrangement acts as a mediator that receives control signals from authorized personnel and executes the locking/unlocking action, preventing direct inadvertent operation by aircrew while maintaining authorized control capability.
2Productivity
If cargo is loaded onto cargo ship for transport, then cargo can be moved when needed, but cargo may move inadvertently due to theft or incorrect selection
Solution Approach 1:
The patent replaces manual mechanical cargo securing methods with an electromagnetic locking system. Electromagnets positioned on the cargo ship deck engage with ferromagnetic materials on cargo items, providing automated magnetic securing instead of manual chain or strap application. This enables reliable cargo position control while maintaining efficient cargo handling through centralized control.
3Reliability
If electromagnetic locking arrangement is provided, then vehicle or cargo can be locked securely, but the system requires electrical power and control infrastructure
Solution Approach 1:
The electromagnetic locking arrangement utilizes the inherent ferromagnetic properties of aircraft wheels and cargo items. The system requires only electrical power activation rather than complex mechanical actuation mechanisms. The electromagnets self-generate the locking force when energized, eliminating the need for additional mechanical linkages, springs, or complex control hardware.
