Solution Overview
Problem
Magnetic devices with strong magnets often attach undesirably to ferrous structures due to magnetic attraction, making precise placement challenging, especially on naval vessels where the desired position is above the waterline.
Innovation Solution
A magnetic device emplacement tool featuring a friction fit head and rotating members that securely hold the device, allowing for controlled attachment and positioning on ferrous surfaces, including telescopic and adjustable features for precise placement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a magnetic device with strong magnets is used to attach to ferrous structures, then the attachment strength is improved, but the precision of placement deteriorates due to undesired magnetic attraction
Solution Approach 1:
The magnetic device is segmented into two functional parts: strong magnets for attachment strength and separate electromechanical actuators for precise positioning. This segmentation allows the attachment function and positioning function to operate independently, resolving the contradiction between strong magnetic attraction and precise placement control.
Solution Approach 2:
An intermediary positioning mechanism is introduced between the magnetic attachment point and the final device position. The electromechanical actuators serve as intermediaries that take over the positioning task after magnetic attachment, eliminating the direct conflict between magnetic force and positioning precision.
2Productivity
If the magnetic device is positioned above the waterline for effective operation, then the operational effectiveness is improved, but the difficulty of attachment increases due to the vessel's draft when laden
Solution Approach 1:
The magnetic attachment is performed preliminarily at an accessible location on the hull, establishing a secure base before the electromechanical positioning system raises the device to the final operational position above the waterline. This preliminary attachment simplifies the overall operation by separating the attachment phase from the positioning phase.
Solution Approach 2:
The system transitions from a static magnetic attachment to a dynamic electromechanical positioning system. The actuators enable the device to move from the initial attachment point to the optimal operational position above the waterline, adapting to the varying draft conditions when the vessel is laden.
