Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If magnetic switch magnets are connected by wire to receive power, then the ladder can be fixed to the hull, but the wire arrangement makes winding and storage inconvenient and may hinder climbing
Solution Approach 1:
The patent replaces the wire-based power transmission system with a wireless power transmission system using electromagnetic fields. The magnetic switch magnets are powered wirelessly through electromagnetic induction, eliminating the mechanical wire connections that hindered winding and climbing operations while maintaining the reliability of the fixed state through controlled magnetic activation.
Solution Approach 2:
The patent extracts and removes the wire component from the system entirely. By eliminating the wire that connected power sources to magnetic switch magnets, the invention resolves the conflict between maintaining fixed reliability and ensuring ease of operation during winding and climbing.
2Ease of operation
If wire is used to supply power to magnetic attachments, then the ladder can be controlled, but wire damage or malfunction causes immediate release and safety accidents
Solution Approach 1:
The patent substitutes the vulnerable wire-based control system with a wireless electromagnetic control system. This replacement eliminates the single point of failure represented by the wire, maintaining ease of control through wireless signal transmission while dramatically improving reliability and safety by removing the risk of wire damage causing immediate ladder release.
Solution Approach 2:
The patent implements prior cushioning by providing backup power and control mechanisms that are independent of the primary wireless system. This ensures that even if the wireless control fails, the ladder maintains its fixed state through redundant magnetic attachments, preventing safety accidents during climbing operations.
3Length of moving object
If the ladder is made long (10-20m) for harbor entry, then pilots can embark/disembark, but the ladder swings seriously causing safety accidents
Solution Approach 1:
The patent applies dynamics by making the magnetic attachment system adjustable and responsive. The magnetic switch magnets can be activated or deactivated based on the ladder's position and movement, allowing the system to adapt to dynamic conditions during harbor entry. This dynamic control reduces unnecessary swinging while maintaining the required length for pilot embarkation and disembarkation.
Solution Approach 2:
The patent changes the magnetic field parameters dynamically along the ladder's length. By adjusting the strength and distribution of magnetic fields at different segments of the 10-20m ladder, the system maintains stability during movement while preserving the full operational length needed for safe pilot transfer between ship and harbor.

AI summary
The purpose of the present invention is to provide a pilot ladder having a remote attachment/detachment function that can safely fix, by using magnetic force, a ladder for a pilot who safely guides a ship to an inner harbor. The present invention relates to a pilot ladder having a remote attachment/detachment function, which comprises a rope (1) and multiple steps (2) and is installed on the outer place of a hull so as to be used when a pilot embarks and disembarks, the pilot ladder comprising: a compartment (100) formed on the bottom surface of each of the steps (2); a magnetic switch magnet module (200) installed in the compartment (100) and provided to be attached to the outer plate (S) of the hull; and a wireless controller (300) provided to control the on/off operations of the magnetic switch manet module (200). In case of using the pilot ladder having a remote attachment/detachment function, a magnetic switch magnet has an improved structure in which the magnetic switch magnet is integrated with a step and the on/off operations thereof are controlled by the wireless controller, and thus an existing wire configuration for magnet control is omitted, so that management required for ladder winding storage is easy, and malfunction of the magnetic switch magnet due to damage to a wire can be prevented.
