Magnetic Release Mechanism for Energy Harvesting Locks

The patent replaces the traditional mechanical force threshold release mechanism with a magnetic field-based release mechanism. The magnetic field interacts with a magnetic element in the handle to control the release, eliminating the need for high mechanical force and improving handle movement quality. This substitution of mechanical system with magnetic field system directly addresses the contradiction by reducing required force while maintaining operational smoothness.

The patent changes the release control parameter from mechanical force threshold to magnetic field strength. By controlling the magnetic field parameters (strength, distribution, and interaction with magnetic elements), the release mechanism achieves smooth handle movement without requiring high extra force. This parameter change allows for precise control of the release point and force requirements.

The patent replaces mechanical energy harvesting components (such as springs, levers, and contact-based generators) with a magnetic field-based energy harvesting system. The magnetic field interacts with magnetic elements during handle movement to generate electrical energy, eliminating mechanical contact and wear. This substitution directly reduces noise and wear while maintaining energy harvesting capability.

The patent introduces a magnetic field as an intermediary between the handle movement and energy generation. Instead of direct mechanical contact, the magnetic field serves as a mediator that converts mechanical motion into electrical energy through electromagnetic induction. This intermediary approach eliminates harmful mechanical interactions while preserving the energy harvesting function.
