Locking Device Self-Powering Generator Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic locking devices face issues with unnatural handling and the requirement of an actuating element for electricity generation, limiting their energy self-sufficiency and compatibility with purely electronic authentication.
Innovation Solution
The locking device incorporates an electrical generator with its movable part arranged in the cylinder core or handle, allowing for energy generation independent of rotational position, using a generator drive member that interacts with the movable part to produce electricity for authentication and clutch operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If a flywheel generator is used to generate electrical energy, then energy self-sufficiency is improved, but handling becomes unnatural and requires initial idle rotation
Solution Approach 1:
The generator is divided into two independent parts: a flywheel for energy storage and a separate drive mechanism for energy generation. The drive mechanism includes a key that can be inserted into a keyway and rotated independently to generate electrical energy, separating the energy storage function from the energy generation function and allowing for more intuitive operation.
Solution Approach 2:
The system performs preliminary action by storing electrical energy in the flywheel during idle rotation or previous operations. When the key is inserted and rotated to generate energy, the stored energy in the flywheel immediately becomes available to power the authentication device and coupling, eliminating the need for initial idle rotation and providing immediate functionality.
2Use of energy by moving object
If a key is required to generate power, then energy generation is achieved, but compatibility with purely electronic authentication is limited
Solution Approach 1:
The key serves multiple functions simultaneously: it acts as both a mechanical key for traditional locking mechanisms and as an energy generation actuator for the flywheel generator. The key can be inserted into the keyway to generate electrical energy, and the same key can be used for purely electronic authentication without requiring separate actuating elements, thereby achieving multi-functionality and enhancing compatibility with various authentication methods.
